Base and Visa Fuel Stablecoin Card Market Surge to $759M Per Month

The stablecoin card market has experienced rapid growth in recent months, reaching $759 million per month in July 2026. This surge is largely attributed to Base, a blockchain network operated by Coinbase, which now accounts for approximately 19% of all tracked crypto card spending volume.

Base's appeal lies in its low transaction fees, fast finality, and native USDC support from Circle. The tight relationship between Coinbase and Circle enables seamless minting, redemption, and settlement on Base, making it an attractive choice for card issuers.

However, Base isn't the only player in this space. Optimism currently leads with 29% market share, while Solana matches Base's 19%. Visa has expanded its stablecoin settlement pilot to include nine blockchains, giving card issuers flexibility but also hedging its bets on a single winner.
