The CLARITY Act faced its first real Senate floor test on Tuesday and fell short. Senators voted 49-50 against cloture on the motion to proceed to H.R. 3633, leaving the crypto market-structure bill 11 votes short of the 60 required to advance.
The cloture vote determined whether the Senate would begin debating the legislation, not whether it should become law. Without the required votes, senators never reached debate, amendments, or a final-passage vote. The House had previously passed its version 294-134 in July 2025, while the Senate Banking Committee advanced the bill 15-9 in May.
Bill Remains on Calendar
Losing cloture does not formally kill H.R. 3633. The legislation remains on Senate Calendar No. 423, allowing Senate Majority Leader John Thune to file another cloture motion if supporters secure additional votes. However, the political obstacles remain substantial.
Last-minute negotiations centered on ethics restrictions involving federal officials and crypto interests. Democrats argued the proposed safeguards were insufficient, while Republicans contended that significant concessions had already been made. All Senate Democrats voted against advancing the bill on Tuesday, joined by three Republicans: Susan Collins, Josh Hawley, and Jerry Moran.
Narrowing Window
With Congress heading toward its pre-election recess, time for floor debate has become scarce. Even a successful cloture attempt would only open the next procedural stage. Senators would still need to debate the motion to proceed, address the legislation itself, handle amendments, and clear another procedural hurdle before final passage.
A post-election lame-duck session offers a potential opportunity, but competing priorities including unfinished spending bills and other business would compete for floor time.
Legislative Reset Looms
If lawmakers do not complete the legislation before the 119th Congress ends, the process restarts in January 2027. Sponsors would need to reintroduce market-structure legislation, move it through committees again, and rebuild a Senate coalition.
Meanwhile, the SEC and CFTC continue operating under existing law and pursuing their own crypto rulemaking agendas. The previously enacted GENIUS Act remains in place.
