$USDC Circle’s USDC stablecoin is making significant strides: it’s set to be accepted as collateral for U.S. futures trading in a landmark move by Coinbase Derivatives and Nodal Clear—pending CFTC approval and expected in 2026; Circle has also partnered with OpenPayd to introduce unified fiat and stablecoin infrastructure for enterprise use; plus, its parent, Circle Internet Group, saw shares jump roughly 6% following the Senate’s passage of the GENIUS Act—a bipartisan bill aimed at establishing a formal federal regulatory framework for stablecoins.
