Rain Secures $58M Series B to Scale Stablecoin Payments Amid Regulatory Greenlight

Rain, a stablecoin infrastructure provider, has closed a $58 million Series B funding round led by Sapphire Ventures, with participation from Galaxy Ventures, Samsung Next, and others. The fresh capital brings Rain's total funding to $88.5 million as it prepares to expand its Visa-backed payment infrastructure across 150+ countries.

The funding follows a 10x growth trajectory and comes as regulatory clarity emerges—including the CFTC's stance on stablecoins and frameworks like the GENIUS Act and MiCA. Enterprise demand is surging, with fintechs, banks, and marketplaces increasingly integrating stablecoins into their payment rails.

Rain's API expansion targets key fintech hubs in Europe, Asia, and Africa, positioning the company to tap into a potential 1.5 billion users. Transaction volume growth underscores the accelerating institutional adoption of stablecoins for cross-border payments.
