Circle launches hourly USDC Match auctions for Mint customers

Circle said it has introduced Circle Match, an hourly auction service for eligible Circle Mint customers that pairs USDC mint and redemption orders and changes the economics of those flows inside Mint. In the company’s Oct. 22, 2026 blog post, matched mints receive the auction fee as a rebate, while matched redemptions pay one uniform clearing fee at or below the Express rate. According to Circle’s announcement, Circle Match is designed for institutions that move USDC at volume and want to match offsetting demand inside Mint rather than through separate OTC desks or exchanges.
