Corporate Case Study | June 2026
India’s Unified Payments Interface processed 21.63 billion transactions worth Rs 27.97 lakh crore in December 2025 alone, the highest monthly volume in the platform’s history. Three companies account for nearly 90% of every rupee that moves through it. PhonePe, backed by Walmart and General Atlantic, commands a 45% share with 600 million registered users. Google Pay, the platform that launched as Tez in 2017 and quietly became India’s second-largest payment app, holds 34 to 35% while reporting near-stagnant revenue of Rs 1,547 crore in FY25. Paytm, the company that built India’s first mass-market digital wallet, invented the QR code culture, survived a near-fatal RBI order on its banking arm in January 2024, and still processed 1.65 billion UPI transactions in December 2025, is clawing its way back. This is the story of how three very different companies came to own the most consequential payments infrastructure in the world, what each one earns from it, and who holds the stronger hand going into the next decade of digital India.

Part IThree Different Origin Stories, One Infrastructure
Paytm: The Wallet That Arrived Before UPI (2010)
Paytm was founded in August 2010 by Vijay Shekhar Sharma in Noida, under the parent entity One97 Communications, which Sharma had founded in December 2000. Paytm began as a prepaid mobile and DTH recharge platform. In 2014, it launched the Paytm Wallet, which became the defining product of India’s first digital payments era. The wallet was a closed-loop system: users loaded money into a Paytm-held balance and transacted within the Paytm ecosystem. It was not interoperable with other banks or payment systems. This was by design in the pre-UPI era, but it became the structural limitation that would cost Paytm its market leadership once UPI launched.
The demonetization of November 8, 2016 was Paytm’s single greatest business event. Overnight, 86% of India’s currency by value was invalidated. Paytm was the only digital payment option with mass-market awareness. The company’s user base grew from approximately 125 million to 200 million registered wallet users in the weeks and months following demonetization. Vijay Shekhar Sharma’s face appeared on newspaper front pages and magazine covers. The government, the media, and the public treated Paytm as synonymous with digital payments in India.
But the demonetization windfall also masked a structural problem. Paytm was slow to embrace UPI, which launched in August 2016, just months before demonetization. While PhonePe built its entire product on UPI from day one, Paytm prioritised its wallet. By the time UPI had reached mass scale, PhonePe and Google Pay had built habits on UPI that Paytm’s wallet-first approach struggled to displace. Paytm’s UPI market share, which was around 14% in July 2021 according to available data at the time of its IPO, has continued to decline since.
PhonePe: Built on UPI Before UPI Existed (2015)
PhonePe was incorporated in December 2015 by Sameer Nigam, Rahul Chari, and Burzin Engineer, three former Flipkart executives who had previously sold their startup Mime360 to Flipkart in 2011. They built PhonePe specifically to operate on UPI, which the National Payments Corporation of India (NPCI) was developing at the same time. Flipkart acquired PhonePe in April 2016, before the app had publicly launched, integrating it as Flipkart’s default payment method and giving it instant distribution to more than 100 million users.
PhonePe went live on UPI in August 2016, making it one of the first third-party apps on the new infrastructure. When demonetization struck in November 2016, PhonePe had a three-month head start on UPI habits versus Paytm’s wallet. It deployed QR codes aggressively at kirana stores, spent heavily on cashbacks to build habits, and leveraged Flipkart’s user base to build scale. By 2018, it had overtaken Paytm in UPI market share. It has not looked back since.
Google Tez / Google Pay: The Latecomer That Conquered Second Place (2017)
Google launched its India-specific payments app, Tez, on September 18, 2017, more than a year after UPI had launched and after both PhonePe and Paytm had established significant UPI user bases. Tez was rebranded to Google Pay on August 28, 2018, aligning it with Google’s global payments brand. Despite launching late, Google Pay grew with exceptional speed, leveraging the Google brand’s trust, the enormous installed base of Android devices in India, deep integration with Gmail and other Google services, and a clean, reliable user interface.
Google Pay’s growth strategy was different from both PhonePe and Paytm. It did not spend on the scale of cashbacks that PhonePe deployed. It did not build its own wallet or banking infrastructure. It rode the UPI rails as a pure third-party application provider, keeping its cost structure lean and using Google’s product quality and brand to acquire and retain users. By 2020, Google Pay had emerged as the clear second-largest UPI app, and the gap between it and PhonePe was smaller than it is today.
The defining structural difference: PhonePe is a standalone fintech company with its own P&L, its own investors, and its own growth ambitions. Google Pay is a product of one of the world’s largest technology corporations; its revenue in India is a rounding error for Alphabet’s global financials. Paytm is a publicly listed company with shareholders, quarterly earnings calls, and a stock price that has been on a challenging journey since its November 2021 IPO. These three ownership structures create fundamentally different incentive systems, risk tolerances, and competitive behaviours.
Part IIWhat UPI Is and Why It Changed Everything
The Unified Payments Interface was developed by the National Payments Corporation of India (NPCI) and launched in April 2016, with the first commercial transactions beginning in August 2016. UPI is a real-time interoperable payment system that allows any bank account holder in India to send money to any other bank account holder instantly, using a mobile application, without knowing the recipient’s bank account number. The transaction is settled through a UPI ID, a mobile number, or a QR code scan.
The critical design choice in UPI was interoperability. Any app can operate on UPI. Any UPI app can transact with any UPI app. A PhonePe user can pay a Google Pay merchant. A Paytm user can receive money from a BHIM user. This interoperability meant that no single company could own the UPI rails the way Visa and Mastercard own card payment rails. NPCI owns the infrastructure. The apps are commoditised distribution channels competing on product, trust, and convenience.
UPI’s growth trajectory has been extraordinary. Transactions grew from 1.207 billion in FY18 to 97.295 billion in FY24. In the full calendar year 2025, UPI processed 228.3 billion transactions with a total value of Rs 299.7 lakh crore, representing 29.3% growth in volume and 20.3% growth in value versus 2024. In December 2025 alone, UPI processed 21.63 billion transactions worth Rs 27.97 lakh crore, a new monthly record. As of early 2026, there are 685 banks live on UPI.

NPCI publishes monthly data on UPI transaction volumes by app. The table below covers verified NPCI data from January 2025 through December 2025, showing the stability of PhonePe’s lead, the consistency of Google Pay’s second place, and the story of Paytm’s partial recovery after the January 2024 crisis.
Two patterns stand out from the monthly NPCI data. First, PhonePe’s market share has declined modestly over the year, from 47.67% in January 2025 to 45.35% in December 2025. This decline is not due to a loss of PhonePe’s absolute volume, which continued to grow from 8.1 billion to 9.81 billion transactions. It reflects the broader market growing faster than PhonePe, with emerging players like Navi, Super.Money, and CRED gaining a combined share that rose from roughly 9% to over 12% through the year. Second, Paytm’s share has recovered incrementally, from 6.78% in January 2025 to 7.65% in December 2025, as it rebuilt its user base after gaining NPCI approval to onboard new UPI users in October 2024.
Part IVRevenue and Financials: Three Very Different Numbers
FY25 Revenue from Operations (Rs Crore) — All Three Players
PhonePe
Paytm
Google Pay
Sources: PhonePe consolidated RoC filings; One97 Communications (Paytm) annual results; Google India Digital Services Private Limited MCA filings via Tofler.
Why three companies with similar UPI market positions report such different revenues: Paytm is a diversified fintech that earns from payments, lending distribution, insurance, and financial services. Its FY25 revenue decline was driven by the RBI restrictions on Paytm Payments Bank (January 2024) which disrupted its wallet and banking revenue streams. PhonePe’s revenue is almost entirely payment services (88.5%), but at a scale and monetisation level that generates Rs 7,115 crore. Google Pay India operates under a narrow mandate from Google’s global structure and earns primarily from payment service fees; its stagnant revenue reflects that Google has not yet monetised its India UPI position aggressively and does not report lending or insurance revenue in the India entity.
| Metric | PhonePe | Paytm (One97) | Google Pay India |
|---|---|---|---|
| FY25 Revenue (Ops) | Rs 7,115 Cr | Rs 6,900 Cr | Rs 1,547 Cr |
| FY24 Revenue (Ops) | Rs 5,064 Cr | Rs 9,978 Cr | Rs 1,490 Cr |
| FY25 YoY Revenue Change | +40.5% | -30.8% | +3.8% (flat) |
| FY25 Net Profit / (Loss) | Rs -1,727 Cr (statutory) | Rs -659 Cr | Rs +50 Cr |
| Adjusted / Underlying PAT (FY25) | Rs +630 Cr (excl. ESOP) | Near breakeven excl. one-time | Rs +50 Cr (statutory) |
| FY25 UPI Mkt Share (vol, Dec) | 45.35% | 7.65% | 34.64% |
| Revenue per % UPI Share (FY25) | Rs 157 Cr per 1% | Rs 901 Cr per 1% | Rs 45 Cr per 1% |
| Ownership | Walmart 71.77% | Public (VSS 19.42%) | Google / Alphabet |
| IPO Status | DRHP filed Jan 2026 | Listed Nov 2021 | Not listed separately |
The “revenue per percentage of UPI share” metric is illuminating. Paytm generates Rs 901 crore per percentage point of UPI market share, far ahead of PhonePe at Rs 157 crore and Google Pay India at Rs 45 crore. This reflects Paytm’s diversified revenue model, where lending distribution, insurance, and financial services amplify the monetisation of each user. PhonePe’s lower revenue per share point reflects a business still heavily concentrated in payment services. Google Pay’s extremely low figure reflects a structurally narrow India revenue mandate.
Part VPhonePe Deep Dive: How It Built and Kept Its Lead
The Five Pillars of PhonePe’s Market Dominance
First-mover on UPI: PhonePe was among the first apps live on UPI in August 2016, three months before demonetization made digital payments urgent for every Indian. This gave it the advantage of being in millions of users’ hands as the payment habit formed under demonetization pressure. A habit formed in a crisis is unusually durable. Users who learned to pay with PhonePe during the November 2016 cash shortage continued using it after the crisis passed, because the habit had been established under genuine necessity rather than promotional incentive alone.
Flipkart distribution: Flipkart acquired PhonePe in April 2016, before the app launched, integrating it as the default payment method across its 100 million-plus user base. Every Flipkart customer who paid via PhonePe experienced UPI payments within an existing high-frequency commerce habit, then discovered that PhonePe also worked for rent payments, utility bills, and money transfers. The Flipkart integration created a cross-sell flywheel that no organic acquisition campaign could have replicated at that speed or scale. Even after the full separation from Flipkart in December 2022, the habits built through years of Flipkart integration remained.
Offline merchant penetration: PhonePe deployed QR codes at kirana stores, auto stands, roadside food vendors, and small retailers across India’s tier-2, tier-3, and rural markets well before competitors recognised the offline merchant opportunity. The result is a merchant acceptance network of over 40 million merchants as of April 2025. This ubiquity creates a dual network effect: consumers stay on PhonePe because it is accepted everywhere, and merchants display PhonePe’s QR because their customers use it. Sound boxes (announcing payment confirmations audibly) extended this merchant relationship into hardware, deepening the lock-in further.
Multilingual from day one: PhonePe launched supporting 11 Indian languages, a deliberate signal that it was building for all of India rather than the English-speaking urban consumer. This language accessibility was critical in tier-2, tier-3, and rural markets, where the majority of India’s population lives and where the next 200 million UPI users would come from. Competitors entered these markets later. PhonePe had already built habits and distribution networks there. The result is a user base that is significantly more geographically and economically diverse than any of its competitors.
Cashback spending that converted into habits: PhonePe spent over Rs 950 crore on cashbacks and incentives in FY19 to accelerate user adoption. This was not sustainable indefinitely, but it was rational as an investment in habit formation. By FY24, that cashback spend had declined to just over Rs 15 crore, a reduction of over 98%, while the user base and transaction volume continued to grow. The users acquired through cashbacks had converted into habitual users who continued transacting without incentive. This is the most critical validation of a consumer payments business model: that users stay after the rewards stop.
PhonePe’s Revenue Model and the Road to Adjusted Profitability
PhonePe reported Rs 7,115 crore in revenue from operations in FY25, up 40.5% from Rs 5,064 crore in FY24. Payment services (including transaction processing fees, platform fees, subscription fees from smart speakers and payment devices, and advertising) accounted for 88.55% of operating revenue at Rs 6,300 crore. Insurance and lending distribution grew 208% to Rs 557.6 crore in FY25. The company reported a statutory net loss of Rs 1,727 crore, driven largely by non-cash ESOP charges. Excluding ESOP costs, adjusted PAT was Rs 630 crore in FY25, up from Rs 197 crore in FY24. Adjusted EBITDA excluding ESOP costs reached Rs 1,477 crore in FY25.
The company has filed its updated DRHP with SEBI in January 2026 for an OFS-only IPO targeting approximately Rs 12,000 crore at a valuation of $14.5 to $15 billion. In October 2025, General Atlantic invested $600 million in PhonePe at a $14.5 billion valuation, its largest single-company bet in India.
Part VIGoogle Pay Deep Dive: The Profitable Underperformer
The Paradox of 35% Market Share and Rs 1,547 Crore Revenue
Google Pay India, which operates through the legal entity Google India Digital Services Private Limited, reported revenue from operations of Rs 1,547 crore in FY25, up marginally from Rs 1,490 crore in FY24. The company has reported broadly flat revenue for five consecutive financial years, hovering between Rs 1,400 crore and Rs 1,550 crore despite holding the second-largest UPI market share in India. Net profit in FY25 was Rs 50 crore, down from Rs 110 crore in FY24 but positive for the fifth consecutive year. Net worth stood at Rs 420 crore in FY25, up from Rs 100 crore in FY21. The company is debt-free with total assets of Rs 2,000 crore.
The paradox is sharp. Google Pay processes approximately 7 to 7.5 billion UPI transactions per month in India, worth trillions of rupees. Yet its India entity earns only Rs 1,547 crore in revenue. The explanation lies in how Google structures its India payments business. UPI P2P transfers generate zero revenue. The India entity earns payment service fees on bill payments, recharges, and in-app commercial transactions. Google’s India entity does not appear to earn the full economics of lending referral fees, insurance distribution, or financial services at the scale that PhonePe does, which are the categories generating PhonePe’s higher revenue per user.
Google Pay’s strategic constraint: Google Pay India is a product of Google’s global organisation, not a standalone fintech company. Its revenue mandate, investment decisions, and product roadmap are set within the context of Alphabet’s global priorities. This means Google Pay India does not operate with the same urgency around monetising its UPI position that PhonePe (which has investors, a pending IPO, and a standalone P&L) does. Google’s co-branded RuPay credit card with Axis Bank, launched in late 2024, is a signal that Google is beginning to take the revenue opportunity more seriously, but the structural constraint of being a large company’s India product rather than an independent fintech remains.
What Google Pay Has That Others Do Not
Despite its revenue underperformance, Google Pay has three structural advantages. First, the Google brand provides a level of trust that no Indian fintech has matched, particularly among the urban, educated, English-speaking user segment. Second, Google Pay’s integration into Gmail, Google Search, and Android creates persistent surface area that independent apps cannot match. A user getting a bill reminder in Gmail and paying it in the same interface is a retention mechanism that requires no active acquisition spend. Third, Google Pay is consistently profitable in India, unlike PhonePe (which has a statutory loss) and Paytm (which reported a Rs 659 crore loss in FY25). Google does not need to manage for quarterly profitability in India; it is already profitable and growing slowly.
Part VIIPaytm Deep Dive: The Comeback After the Crisis
The RBI Crisis: January 2024 to October 2024
On January 31, 2024, the Reserve Bank of India issued an order restricting Paytm Payments Bank Limited (PPBL) from accepting any new deposits, credit transactions, or top-ups in customer accounts, prepaid instruments, wallets, FASTags, or National Common Mobility Cards after February 29, 2024. The restrictions effectively shut down PPBL as an operating bank. The RBI cited persistent non-compliance and significant supervisory concerns, without specifying the exact nature of the violations publicly.
The impact on Paytm’s share price was immediate and severe. One97 Communications’ stock fell over 50% in the weeks following the announcement. The company’s UPI market share, which had been approximately 10% in early 2024, declined to 6.78% by January 2025, as the uncertainty around the banking arm discouraged new users and some existing users migrated to other apps.
The resolution was structured in phases. In February 2024, the RBI advised NPCI to facilitate Paytm’s migration of UPI users from the @paytm handle (operated by PPBL) to new handles at partner banks. In March 2024, NPCI approved Paytm to continue UPI transactions as a Third-Party Application Provider through four partner banks: State Bank of India, Axis Bank, HDFC Bank, and YES Bank. In October 2024, NPCI granted Paytm approval to onboard new UPI users, ending the nine-month restriction on new user acquisition. In November 2025, Paytm received its payment aggregator licence from the RBI, clearing the path for its online merchant payments business. In April 2026, the RBI formally cancelled PPBL’s banking licence, ending the entity’s existence but confirming that Paytm’s core payments business had successfully decoupled from its banking arm.
The financial cost of the PPBL crisis: Paytm’s revenue from operations fell 30.8% from Rs 9,978 crore in FY24 to Rs 6,900 crore in FY25, the most direct financial consequence of the RBI action. The company wrote off Rs 2,271 crore as impairment of its investment in PPBL. Its stock price has not recovered to its November 2021 IPO price of Rs 2,150 per share. However, Paytm’s losses also narrowed by over 50%, from Rs 1,422 crore in FY24 to Rs 659 crore in FY25, reflecting significant cost reduction and the company’s improving EBITDA trajectory before ESOP expenses.
Paytm’s Recovery Metrics
By December 2025, Paytm was processing 1.65 billion UPI transactions per month, up from 1.15 billion in January 2025, a 43.5% increase in just twelve months. This recovery was driven by the ability to onboard new users from October 2024 onward and the stabilisation of the merchant base, which had contracted by approximately one million merchants in the January to March 2024 period before recovering. The company guided for Q1 FY26 profitability at the PAT level, and founder Vijay Shekhar Sharma stated in his post-FY25 earnings call that he was confident of PAT profitability in the first quarter of FY26.
Paytm’s competitive advantage that survived the crisis was its merchant base and its Soundbox device network. Despite the banking restrictions, merchants did not abandon Paytm in large numbers because the QR code and Soundbox ecosystem remained functional. The Soundbox, which announces payment confirmations audibly, had been deployed at millions of kirana stores and small merchants across India. This physical presence at the point of sale is a distribution asset that neither PhonePe nor Google Pay has matched in device terms.

Part VIIIHead-to-Head Strategic Comparison
PhonePe
Core strength: Scale, merchant network, Flipkart/demonetization legacy habits, multilingual reach, Walmart capital depth.
Revenue moat: Insurance and lending distribution growing 208% YoY. Smart speaker hardware subscriptions. Growing non-payments revenue.
Key risk: NPCI 30% market cap (currently deferred to December 2026). 88.5% revenue concentration in payments. Statutory net losses from ESOP.
IPO signal: Filed DRHP January 2026 targeting $1.5 billion at $14.5 to $15 billion valuation. OFS-only; no fresh capital raised.
Google Pay
Core strength: Google brand trust, Android ecosystem integration, profitable without aggressive investment, zero debt.
Revenue moat: Payment service fees on bill payments and commercial transactions. RuPay co-branded credit card (Axis Bank, late 2024).
Key risk: Revenue near-stagnant at Rs 1,547 crore for five years. No independent P&L pressure to monetise aggressively. Falls furthest behind on lending and insurance distribution.
Strategic intent: Credit card launch and lending expansion signal Google beginning to take monetisation more seriously, but pace remains slow versus PhonePe.
Paytm
Core strength: Soundbox merchant hardware, lending distribution (Rs 4,315 crore merchant loans in Q4 FY25), payment aggregator licence, publicly listed with full financial disclosure.
Revenue moat: Financial services (lending, insurance) generate highest revenue per UPI share point. Merchant device ecosystem creates physical lock-in.
Key risk: Post-crisis user base below pre-2024 levels. Stock has not recovered to IPO price of Rs 2,150. Regulatory credibility requires sustained clean compliance record.
Recovery trajectory: Q4 FY25 EBITDA before ESOP positive at Rs 81 crore. PAT profitability targeted for Q1 FY26.
Part IXThe Regulatory Battlefield
In 2020, NPCI proposed a rule that would limit any single third-party UPI application to 30% of total UPI transaction volume. At the time, PhonePe had approximately 42 to 44% market share. Google Pay was close to 35%. Both companies were significantly above the proposed cap. NPCI deferred implementation repeatedly, with the latest deferral extending the deadline to December 2026.
If enforced at the current market structure, PhonePe would need to reduce its share by approximately 15 to 17 percentage points from its current 45%. This would require stopping new user acquisition and allowing competitors to grow until the cap is met. Google Pay, at approximately 35%, would also need to reduce its share by 5 percentage points. The primary beneficiaries would be Paytm and the emerging players.
The repeated deferrals suggest NPCI is uncomfortable with penalising market leadership achieved through product quality. However, the rule has not been withdrawn, and its enforcement risk is the single most significant regulatory overhang on PhonePe’s IPO.
The government’s Merchant Discount Rate policy mandates zero MDR for UPI transactions at most merchant categories. This means that when a consumer pays a kirana store via PhonePe, Google Pay, or Paytm, neither the app nor any bank earns a per-transaction fee from that payment. Basic person-to-person transfers are also free. The billions of daily UPI transactions generate no direct fee revenue for the apps processing them.
Revenue is earned only on value-added layers above the basic UPI transaction: bill payments, insurance distribution, lending referral fees, device subscription fees, and advertising. This is why PhonePe’s revenue, despite processing 45% of all UPI transactions, is concentrated in these service layers rather than in transaction volume.
The industry expectation, noted in Paytm’s Q4 FY25 earnings release, is that the government may eventually allow MDR for UPI transactions above Rs 2,000 at large merchants. If introduced, this would generate substantial incremental revenue for all three apps and would disproportionately benefit the market leader, PhonePe.
Approximately 10% of PhonePe’s FY24 revenues came from government subsidies and RBI incentives provided to support the digital payments sector. Paytm received Rs 288 crore in UPI incentives in FY24 and Rs 70 crore in FY25, significantly lower year-on-year. This decline in government incentives contributed to Paytm’s revenue compression in FY25. If the government reduces or eliminates these incentives as UPI matures, all three players face a revenue headwind. PhonePe, with the broadest diversification into insurance and lending, is best positioned to absorb such a reduction. Paytm, which named the decline in incentives as a contributing factor in its Q4 FY25 earnings commentary, is most exposed.
Part XThe Challengers: Navi, Super.Money, CRED, WhatsApp Pay
The combined market share of PhonePe, Google Pay, and Paytm declined from approximately 93% in early 2025 to roughly 87 to 88% by December 2025 as newer players gained ground. Four challengers deserve attention.
Navi processed 678 million UPI transactions in December 2025, giving it approximately 3.1% of total UPI volume. Navi’s differentiation is the integration of credit directly into the payment flow, allowing users to access credit lines for UPI transactions. This model targets the segment of consumers who want to pay via UPI but do not have the balance in their account at that moment, a large and underserved population.
Super.Money, backed by Flipkart (and therefore indirectly by Walmart, the same entity that owns PhonePe), processed 287 million transactions in December 2025. Super.Money has grown rapidly by deploying aggressive cashbacks, reflecting a strategy similar to PhonePe’s 2017 to 2019 playbook. Its rise is notable because it represents Walmart simultaneously competing against itself: one Walmart asset (PhonePe) competing with another (Super.Money).
CRED processed approximately 126 million UPI transactions in February 2025. CRED’s user base is narrower and higher-income, and its UPI product is an extension of a credit card management and lifestyle rewards platform rather than a mass-market payments app. It does not compete for the same users as PhonePe or Google Pay in tier-2 and tier-3 markets.
WhatsApp Pay had its user onboarding cap lifted by NPCI in December 2024, enabling it to scale beyond the previous 100 million user limit. WhatsApp Pay processed 61 million transactions in January 2025, more than double the 26 million it processed in January 2024. With WhatsApp’s 500 million-plus users in India, WhatsApp Pay has the potential to become a significant fourth player if Meta invests in it aggressively. The NPCI cap removal is the enabling condition; whether Meta monetises it aggressively or uses it purely as an engagement feature remains to be seen.
Part XIWho Owns the UPI Market and Who Will Win the Next Decade
PhonePe: Dominant but Capped
PhonePe owns the UPI market today. It has the users, the merchants, the habits, the infrastructure, and the capital backing to defend its position. Its path to the next decade runs through successful IPO execution, the 30% cap outcome, and whether it can shift from a payments-first to a financial-services-first revenue profile. If the cap is not enforced and if insurance and lending continue growing at 200%+ annually, PhonePe in 2030 could be a materially different, far more profitable business.
Google Pay: Undermonetised but Unbreakable
Google Pay will not lose its 35% market share through any realistic competitive scenario. The Google brand and Android integration are too deeply embedded. But it will not meaningfully grow its revenue share without a deliberate decision by Alphabet to invest in India fintech monetisation. The Axis Bank RuPay credit card is a start. If Google decides to take lending and insurance distribution seriously, it has a user base and brand that could generate revenue orders of magnitude higher than Rs 1,547 crore. If it does not, it remains a profitable but strategically passive player.
Paytm: Rebuilt, Not Recovered
Paytm has shown that it can survive an existential regulatory event and rebuild. Its merchant base, Soundbox hardware, and lending distribution are genuine competitive assets. The path back to its pre-crisis revenue of Rs 9,978 crore in FY24 requires time, sustained regulatory compliance, and successful execution on the PA licence opportunity. The stock market has not fully reflected the recovery. Whether Paytm can return to 10%+ UPI market share from 7.65% today is the test of whether the crisis was a temporary disruption or a permanent reset.
The Answer to Who Owns UPI
Nobody owns UPI. That is by design. NPCI built an infrastructure that no private company controls, and it has kept it that way through the zero MDR regime, the 30% market cap rule, and the demonstrated willingness to act against non-compliant players. The apps are tenants on a government-owned highway.
Within that constraint, PhonePe commands the largest share of traffic on that highway and earns the most revenue from the services it sells to people driving on it. Google Pay holds the second lane with extraordinary stability and minimal investment. Paytm had a near-accident, survived, rebuilt its engine, and is accelerating again.
The next decade’s winner will not be determined by who processes the most UPI transactions. Zero-MDR means transaction volume alone cannot be monetised. The winner will be determined by who converts those transactions most effectively into insurance premiums sold, loans distributed, investment accounts opened, and merchant services subscribed. By that metric, the race is genuinely open. PhonePe has the largest user base to cross-sell into. Google has the deepest brand trust. Paytm has the most proven financial services monetisation per user. All three are running toward the same destination from different starting positions.

Frequently Asked Questions
PhonePe held a 45.35% share of UPI transaction volume in December 2025, processing 9.81 billion transactions worth Rs 13.61 lakh crore in that month alone. In January 2025, its share was higher at 47.67% with 8.1 billion transactions. The modest decline in percentage share reflects the broader UPI market growing faster than PhonePe in absolute terms, with emerging players like Navi and Super.Money gaining share. PhonePe’s absolute transaction volumes have continued growing throughout this period. It remains the largest UPI application in India by a substantial margin, processing approximately 330 million transactions daily as of April 2025.
Google Pay India’s revenue of Rs 1,547 crore in FY25 reflects a narrow mandate from Google’s global organisation. The India entity earns payment service fees on commercial transactions (bill payments, recharges, commercial payments) but has not aggressively monetised lending distribution, insurance, or financial services at the scale that PhonePe has. Additionally, UPI P2P transfers are zero-MDR for all apps, meaning the billions of person-to-person transfers Google Pay processes generate no fee revenue. Google Pay India has been broadly flat in revenue for five years, between Rs 1,400 and Rs 1,550 crore, despite growing its transaction volumes. The launch of a co-branded RuPay credit card with Axis Bank in late 2024 suggests Google is beginning to take revenue generation from its payments position more seriously.
On January 31, 2024, the RBI issued an order restricting Paytm Payments Bank Limited from accepting new deposits, credit transactions, and providing UPI facilities after February 29, 2024, citing persistent non-compliance and supervisory concerns. The restrictions effectively closed PPBL as an operating bank. Paytm’s stock fell over 50% in the weeks following the announcement and its UPI market share declined from approximately 10% to 6.78% by January 2025. The recovery was structured in phases: NPCI approved Paytm to continue UPI services as a TPAP through four partner banks in March 2024, and cleared it to onboard new UPI users in October 2024. In November 2025, Paytm received its payment aggregator licence from the RBI. In April 2026, the RBI formally cancelled PPBL’s banking licence, with the regulator confirming sufficient liquidity for all depositors. Paytm’s core payments business continues operating independently of PPBL. By December 2025, Paytm was processing 1.65 billion UPI transactions per month, up from 1.15 billion in January 2025.
In 2020, NPCI proposed a rule capping any single third-party UPI application at 30% of total UPI transaction volume, to prevent over-concentration and systemic risk. Both PhonePe and Google Pay have consistently exceeded this threshold. NPCI has repeatedly deferred enforcement, most recently extending the deadline to December 2026. If enforced, PhonePe would need to reduce its share by approximately 15 to 17 percentage points from its current 45%, and Google Pay would need to reduce its share by approximately 5 percentage points. This would require stopping new user acquisition until the market share fell to 30%. The beneficiaries would be Paytm, Navi, Super.Money, and other emerging UPI apps. The rule has not been formally withdrawn, and its potential enforcement is one of the most significant regulatory risks facing PhonePe ahead of its IPO.
Basic UPI person-to-person transfers are zero-MDR and generate no fee revenue for any app. Revenue is earned through service layers above the basic UPI infrastructure. For PhonePe, this includes transaction processing fees on commercial transactions (bill payments, digital gold, travel bookings), platform fees, subscription fees from smart speaker devices, advertising fees, insurance distribution commissions (Rs 557.6 crore in FY25), and lending referral fees. For Paytm, revenue comes from payment processing on merchants, merchant device subscriptions (Soundbox), lending distribution (Rs 4,315 crore of merchant loans in Q4 FY25 alone), and insurance. For Google Pay India, revenue comes primarily from payment service fees on commercial transactions. All three also receive government incentives from the RBI for supporting digital payments, though this stream has been declining. Paytm received Rs 288 crore in UPI incentives in FY24 and only Rs 70 crore in FY25.
