Coinbase Global (COIN), the top US crypto exchange, exploded 16.3% higher on Wednesday, while Circle Internet Group, owner of the USDC stablecoin, rallied 33.8%. Additionally, the new rules for stablecoins in the US are frightening investors in credit card issuers with the possibility that retailers will circumvent swipe fees.

Less than two weeks after its IPO, Circle Internet’s market capitalization has surpassed that of nearly half of the S&P 500’s companies.
