The Digital Asset Market Clarity Act, known as the CLARITY Act, suffered a major setback in the U.S. Senate on Sept. 15 after falling short of the 60 votes required to advance. Senators voted 49–50 against invoking cloture on the motion to proceed to H.R. 3633, blocking the chamber from opening formal debate on the crypto market structure legislation. The failed vote follows more than a year of negotiations spanning digital asset oversight, ethics restrictions, stablecoin-related provisions and the scope of federal regulatory authority. While the bill remains procedurally alive, its near-term path in the Senate is now significantly more difficult. The cloture vote represented the first full Senate floor test for the measure. Backers not only missed the 60-vote threshold, they also failed to secure a simple majority, leaving Senate leaders without enough support to begin consideration. The House approved H.R. 3633 in July 2025 by a 294–134 margin, including support from 78 Democrats alongside Republicans. The Senate Banking Committee advanced its version in May 2026 on a 15–9 vote. Lawmakers then spent months working through more than 600 pages of legislative text before bringing the bill to the floor Tuesday afternoon. Several Democrats who participated in the negotiations ultimately voted against cloture. Reporter Eleanor Terrett said Kirsten Gillibrand, Mark Warner, Cory Booker, Raphael Warnock, Ruben Gallego, Angela Alsobrooks and Catherine Cortez Masto voted no. Terrett also reported an industry leader texted after the vote: "It died." Republican opposition also contributed. Susan Collins, Josh Hawley, Jerry Moran and Thom Tillis voted no, according to the reported tally. Mitch McConnell, back in the Senate this week, voted to advance the legislation. Even with most Republicans supporting the motion, GOP votes alone were not enough to meet the 60-vote requirement. After the vote, Ripple CEO Brad Garlinghouse said: "There is still reason for optimism for crypto in the United States. Now, the SEC, under Chair Atkins, and the CFTC, under Chair Selig, will continue to work hard to issue rules to fill the legislative gap and we will continue to be actively engaged in that rulemaking process." Negotiators made 126 changes to the latest draft as they sought a bipartisan breakthrough. The revised package addressed ethics rules for senior federal officials, state attorney general enforcement authority, protections for noncustodial developers, miners and validators, and provisions tied to stablecoin rewards. The ethics section remained the central sticking point. Democrats pushed for broader restrictions that would also apply to dependent children of federal officials. Republicans rejected a Democratic counterproposal ahead of the vote. Gallego later said Republican leaders ended negotiations while talks over the ethics language were still ongoing. Senator Cynthia Lummis issued a final appeal on the Senate floor, urging colleagues to support the motion and continue shaping the legislation. The push failed to move enough senators into the "yes" column. Senate leadership can file another cloture motion, meaning the CLARITY Act remains on the legislative calendar. Time is tight, with limited runway in the current session before the election recess and year-end deadlines. Any renewed effort would still require bipartisan backing to clear the same 60-vote hurdle. With the bill stalled, attention shifts back to regulators. The Securities and Exchange Commission and the Commodity Futures Trading Commission continue developing crypto policy under existing authority. The SEC has proposed Regulation Crypto Assets, while agencies are also working on securities tokenization and other digital asset initiatives. The CLARITY Act is designed to define how federal agencies oversee cryptocurrencies and blockchain projects and to grant the CFTC new authority over parts of the crypto spot market.
