Stablecoin Market Capitalization Surges Past $310 Billion Amid GENIUS Act's First Year

The GENIUS Act, signed by President Donald Trump on July 18, 2025, has led to significant growth in the stablecoin market. The total stablecoin market capitalization is approximately $310 billion, with USDT holding around $184 billion and USDC holding about $73 billion. This represents a 50% increase since early 2025.

Kyle Sonlin, president and co-founder of Global Settlement Network, noted that his conversations with governments and institutions have shifted from explaining why stablecoins matter to accepting them as financial infrastructure. He attributes this change in attitude to the GENIUS Act's credibility and regulatory framework.

Visa has also been expanding its stablecoin settlement pilot, supporting nine blockchains by April and reaching a $7 billion annualized settlement run rate. In July, Visa introduced an enterprise platform providing access to stablecoin storage, redemption, minting, and burning through a single managed environment.
