The Senate rejected the Digital Asset Market Clarity Act, known as the CLARITY Act (H.R. 3633), by a 49-50 vote on September 15, 2026. The measure needed 60 votes to clear a cloture vote, which limits debate and allows legislation to proceed, leaving it 11 votes short of the required threshold. Every Democrat opposed advancing the bill, joined by four Republicans. Senator Cynthia Lummis, one of its lead champions, blamed Senate Democrats for prioritizing opposition to President Trump over consumer rights and said the vote delayed protections for digital-asset users and weakened US leadership in the sector. The legislation, led by Lummis alongside Senators John Boozman and Tim Scott, sought to establish a comprehensive regulatory framework and clarify the respective authority of the SEC and CFTC (U.S. derivatives regulator) over crypto markets. Democratic senators submitted more than 120 amendments during negotiations, expanding the bill from approximately 300 pages to more than 600. Bitcoin fell approximately 3% after the vote, while Coinbase and Circle shares dropped 8% and 10%, respectively. Lummis indicated the bill is effectively dead for the current Congress and unlikely to return until 2030, with federal agencies expected to continue shaping crypto regulation through guidance and enforcement in the meantime.
