Razorpay Launches Vulcan — India’s First AI Foundation Model for Payments

Razorpay has launched Vulcan, a transformer-based AI foundation model built specifically for payments processing — not an LLM, but a purpose-built architecture that treats each payment as an unordered set of fields, tokenising even missing values. Trained on roughly 3 trillion data points from 4 billion transactions and weighing about 3,000 signals per transaction, Vulcan collapses routing, fraud detection, risk scoring and checkout personalisation into a single model. Built with NVIDIA and AWS, the model is already in beta across 51,000 businesses. Early results: 8–10% better payment success rates, 8x more international card fraud blocked, and 5x more fraudulent transactions caught without additional false-positive alerts. The approach diverges from Nubank’s nuFormer and Revolut’s PRAGMA — both sequence models optimised for card-heavy markets — because India’s payment landscape (UPI, cards, netbanking, COD) needs a set-based approach rather than sequential ordering.

SEBI to Examine Whether NSE Can Trade Its Own Shares

SEBI is set to evaluate the Permitted-to-Trade (PTT) framework in the context of NSE’s proposal to allow its own shares to trade on its platform ahead of its blockbuster IPO. The issue size is estimated at up to ₹30,000 crore based on NSE’s unlisted market valuation of ~₹5 lakh crore. The complication: the Securities Contracts (Stock Exchanges and Clearing Corporations) Regulations, 2018 prohibit a stock exchange from listing on its own platform or on an exchange operated by its associates. NSE’s May 2026 circular argued that PTT admission — which allows a security to trade without formal listing — is distinct from self-listing. SEBI will reportedly assess liquidity concentration and the precedent this sets for market infrastructure institutions. The regulator granted a no-objection certificate for the IPO earlier this year; the board approved the listing proposal in February. Hindu Business Line

Government Weighs MDR Return vs. Phased Incentive Taper for UPI

The Department of Financial Services has told a parliamentary panel it is considering two routes to address UPI’s funding sustainability: (1) reintroducing Merchant Discount Rate (MDR) on person-to-merchant transactions above ₹2,000, or (2) a tiered incentive structure that gradually phases out government support. A Moneycontrol analysis breaks down who gets what under each scenario — banks, fintechs, and NPCI all have different exposure. Meanwhile, a Business Standard analysis argues that India’s data-protection rules are narrowing fintech’s regulatory arbitrage window, raising compliance costs while creating openings in regtech and cyber-risk. The zero-MDR era, it appears, is living on borrowed time. Moneycontrol · Business Standard
