a16z: Stablecoins are evolving from trading tools to core financial infrastructure, with Q1 trading volume reaching $4.5 trillion

a16z released the latest research indicating that stablecoins are gradually evolving from their initial role as transaction settlement tools and stores of value into global financial infrastructure. Data shows that following the regulatory clarity driven by the U.S. GENIUS Act, the stablecoin market has accelerated its growth, with adjusted trading volumes reaching approximately $4.5 trillion.

The report shows that consumer-to-business (C2B) stablecoin transactions grew by 128% year-on-year, reaching 284.6 million transactions. The monthly collateral deposits for stablecoin card projects also increased from nearly zero at the end of 2024 to over $300 million by early 2026, reflecting the rapid expansion of stablecoin payment scenarios. Meanwhile, the velocity of stablecoins has increased from 2.6 times to 6 times since early 2024, indicating a shift from being "held" to being "frequently used." a16z believes that the focus of stablecoin applications is shifting from cross-border payments to local payment infrastructure, particularly evident in markets such as Asia and Brazil.
