The Senate blocked the Digital Asset Market Clarity Act on September 15 when a cloture vote to proceed to debate on H.R. 3633 failed to reach the required 60-vote threshold. Opposition reached 41 votes, making passage mathematically impossible.
The cloture vote at approximately 2:15 p.m. ET was a procedural test to begin debate on the bill, not a vote on final passage. Once 41 senators voted against cloture, even unanimous support from the remaining senators could only reach 59 votes.
The legislation had undergone extensive compromise. Republican sponsors incorporated 126 changes requested by Democrats in their latest offer, including an ethics framework for federal officials, state attorney general enforcement provisions, protections for non-custodial developers and miners, and a Treasury "circuit breaker" mechanism for stablecoins.
Two Senate Democrats who had previously supported the bill in the Banking Committee changed their positions on the floor vote. Senators Ruben Gallego of Arizona and Angela Alsobrooks of Maryland voted against cloture after backing H.R. 3633 in the May committee vote.
Senator Mitch McConnell, the Kentucky Republican who returned to the Capitol this week after a three-month absence following a June fall and hospitalization, voted to advance the legislation.
The CLARITY Act had advanced further than typical crypto legislation. The House passed the bill 294-134 in July 2025, with 78 Democrats joining Republicans. The Senate Banking Committee approved it 15-9 in May 2026.
While the bill remains technically on the Senate calendar and leadership could attempt another cloture vote after the required intervening days, legislative options have narrowed. The shortened September session, upcoming October election recess, and House schedule changes have reduced the pathway for identical legislation to pass both chambers before the end of 2026.
