The Senate voted 49-50 against advancing H.R. 3633, the Digital Asset Market Clarity Act, falling 11 votes short of the 60 needed for cloture and a full floor debate. The vote on September 15, 2026, came after the House approved the bill 294-134 in July 2025 and the Senate Banking Committee endorsed it 15-9 in May 2026. Bitcoin social volume reached a 14-day high that day, surpassing discussion around the Federal Reserve's recent rate decision. Bitcoin, already down roughly 5% from a peak near $79,500, fell another 1.7% toward and below $76,000. Coinbase and Circle also posted sharp equity declines. The bill would have clarified whether digital assets fall under the CFTC (U.S. commodities regulator) or SEC (U.S. securities regulator), while creating a route for some tokens to shift from securities to commodities as networks matured and decentralized. Ethics provisions concerning government officials' digital-asset profits drove Democratic objections, while four Republicans, including Susan Collins and Josh Hawley, also opposed advancing it. Prediction markets put the legislation's chances of becoming law in 2026 into the single digits after the vote.
