The Senate failed to advance the Digital Asset Market Clarity Act on September 15, 2026, after 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 received Senate Banking Committee approval on May 14, 2026, but negotiations stalled over ethics rules for public officials holding digital assets and whether stablecoins could pay yields. Its defeat leaves the Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC) contesting jurisdiction under existing rules, while a motion to reconsider technically remains pending. Patrick Witt said President Donald Trump had accepted unprecedented provisions barring federal officials from issuing or sponsoring digital assets and requiring officials to divest significant holdings or place them in a blind trust. Polymarket odds fell from about 82% in February 2026 to the mid-to-high 20s by the vote, although the older account cited a 6.2% 2026 enactment estimate.
