Rain Must Compete on Software
Rain
Rain’s edge gets weaker as stablecoin settlement moves from startup workaround to network feature. Rain originally won by letting crypto native businesses spend self custodial USDC through cards, repay from wallets, and avoid repeated off ramps into bank accounts. Once Visa and Mastercard offer more native stablecoin settlement inside their own networks, that plumbing matters less on its own, and the buying decision shifts toward controls, reconciliation, approvals, and enterprise workflow software.

Rain already monetizes like a card software company, through interchange and subscription fees, not through some exclusive blockchain toll. That means if network level stablecoin settlement becomes widely available, pricing power on the payments layer is likely to narrow first, while the durable margin moves to software that finance teams use every day.

The product itself points in that direction. Large customers use Rain for reimbursements, accounting integration, mixed on chain and bank account payouts, and global spend management. Those are workflow products, not just payment rails. They are also the same areas where Brex and Ramp have trained buyers to expect tight controls and clean books, not novel settlement mechanics.

The networks are clearly moving downmarket into Rain’s territory. Visa launched USDC settlement for U.S. institutions in December 2025, and Mastercard expanded stablecoin settlement and card capabilities across its network in 2025 and 2026. At the same time, Rain partnered with Lithic in September 2025 to widen processing reach, which shows distribution and program tooling are becoming just as important as proprietary rail design.
Going forward, the winners in stablecoin cards will look less like specialty rail providers and more like modern finance software companies with stablecoin support built in. Rain is positioned to follow that path. Its best route is to turn its early rail advantage into the default operating layer for treasury, spend, payouts, and reporting across hybrid on chain and fiat businesses.
