Circle Internet Group, Inc.Circle's Arc mainnet launch with major institutional validators and native USDC gas drives adoption.
On September 16, Circle's Arc mainnet goes live with a validator cohort including BlackRock, DTCC, Mastercard, and Visa, even as the CLARITY Act faces a likely Senate cloture failure the day before. The Layer-1 blockchain features native USDC gas and sub-second finality, with BlackRock expected to deploy its $3.2 billion BUIDL fund and DTCC planning to tokenize assets from its $114 trillion custody portfolio starting in 2027. The CLARITY Act, which needs 60 votes but has only 53 Republican seats and expected defections, has Polymarket odds for 2026 passage at 15%, down from 90% in February. Institutions are instead aligning with the GENIUS Act's January 18, 2027 enforcement date and agency rules from the OCC and SEC, signaling a pivot to infrastructure-led compliance. This move reflects a capital-allocation decision by institutions that read NPRMs, not Polymarket.
