PhonePe and Google Pay’s 79% UPI share tests 30% cap enforcement
PhonePe and Google Pay accounted for about 79% of UPI transactions in May, leaving NPCI’s 30% per-app market-share cap difficult to implement ahead of the December 31, 2026 deadline. Proposed MDR on merchant payments above ₹2,000 from October 15 could improve monetisation for smaller UPI apps.
The development
PhonePe and Google Pay retained around 79 per cent of UPI transactions in May 2026, complicating enforcement of the 30 per cent app market-share cap due December 31, 2026. MDR on merchant payments above ₹2,000 from October 15 could aid smaller apps.

Why it matters to operators and investors
Payments-focused deal teams should evaluate partnerships or acquisitions among smaller UPI apps, merchant acquirers and loyalty-payment platforms that could gain distribution if cap enforcement shifts transaction share from the incumbents.
What to watch next
- NPCI clarification on whether the 30% cap applies to transaction volume, value, new-user acquisition, or phased incremental share reductions.
- Any formal extension, exemption, transition schedule or enforcement mechanism announced before December 31, 2026.
- Confirmation of MDR applicability, rate structure, merchant category exclusions and treatment of transactions above ₹2,000 from October 15.
- Monthly UPI market-share data for PhonePe, Google Pay, Paytm, BHIM, bank apps and emerging PSPs.
- Merchant payment-success rates and decline codes by UPI app, bank and transaction-value band.
- Changes in cashback, retailer-funded incentives, default-app placement, bank partnerships and QR-acquiring offers from smaller players.
- Consumer migration signals such as app downloads, active-user growth, linked-bank-account additions and repeat-payment frequency outside the top two apps.
- Add and actively test at least three UPI payment rails, including a bank-led or smaller PSP option, rather than relying on PhonePe and Google Pay alone.
- Upgrade checkout orchestration to route UPI transactions by real-time success rate, bank availability, cost and app-level capacity constraints.
- Negotiate MDR and payment-acceptance terms for transactions above ₹2,000 before any October 15 pricing change; assess whether surcharging is permitted and commercially viable.
- Use targeted offers to encourage low-cost or high-success payment methods without creating checkout friction or violating UPI rules.
- Build contingency playbooks for QR-code replacement, PSP outages, payment-status reconciliation and customer-service handling if caps create transaction failures.
- Track whether smaller UPI apps offer merchant acquisition subsidies, faster settlement, loyalty tools or preferential MDR that can offset lower consumer familiarity.
The counter-case
The 79% combined share is not itself evidence that the 30% cap will fail: the cap applies per third-party app, not to the top two collectively, and both may be able to reduce share gradually through bank-app routing, incentives, partnerships, or user migration before December 2026. NPCI could also enforce compliance through transaction throttles, onboarding restrictions, or mandated interoperability changes. The proposed MDR may not materially help smaller apps if merchants resist fees, regulators dilute the proposal, or the largest apps retain superior distribution and user trust.
