The Senate failed to advance the Digital Asset Market Clarity Act on September 15, 2026, when a cloture motion received a 49-50 vote, below the 60 votes required to begin formal debate. The bill had passed the House 294-134 on July 17, 2025, and won Senate Banking Committee approval on May 14, 2026, but negotiations later stalled over ethics rules for public officials holding digital assets and whether stablecoins (crypto tokens designed to maintain stable value) could pay yields to holders. Polymarket, a decentralized prediction market (platform for trading event outcomes), put the bill's passage odds near 82% in February 2026 before they fell to roughly 32% by mid-July and the mid-to-high 20s by the vote. The market ultimately reflected the bill's likely failure but began from an overconfident baseline and adjusted slowly. Every Democratic senator opposed advancing the bill, joined by four Republicans, including Susan Collins and Josh Hawley. A motion to reconsider was filed, but the proximity of midterm elections and current Senate dynamics make revival before year-end extremely unlikely. The bill's defeat leaves the Securities and Exchange Commission and Commodity Futures Trading Commission contesting jurisdiction over digital assets, with enforcement actions continuing to shape market rules. It also leaves unresolved whether stablecoins can pay interest, a question that could affect competition with bank deposits and money market funds.
