CLARITY Act Cloture Filing Sets Up Senate Vote by Mid-September

Senate Majority Leader John Thune filed cloture on the motion to proceed to H.R. 3633, the Digital Asset Market Clarity Act, just before the chamber adjourned for its August recess. The filing puts the crypto market structure bill in position for a potential cloture vote soon after the Senate returns September 14.

Cloture is a procedural tool that ends debate and allows the Senate to begin formal consideration of a bill. It requires 60 votes in the 100-seat chamber. If the motion succeeds, senators can then debate amendments and eventually vote on final passage.

The central question is whether Thune can assemble 60 votes. The House passed its version 294-134 in July 2025. The Senate Banking Committee advanced its version 15-9 in May 2026. Senators continued negotiating after that markup. On July 22, Cynthia Lummis released updated text combining work from the Banking and Agriculture committees and said negotiations with Democrats were ongoing.

A committee vote is one thing. The full Senate floor is another. With 60 votes needed for cloture, Republican leadership will need Democratic support unless attendance or procedural circumstances change the arithmetic.

The legislation attempts to resolve a problem that has shaped U.S. crypto policy for years: determining when a digital asset falls under securities regulation and when trading belongs primarily under commodities law. The updated Senate text creates a federal framework giving the Commodity Futures Trading Commission direct authority over spot digital commodity markets conducted through registered entities, including digital commodity exchanges, brokers and dealers. The SEC retains responsibility for securities-related activity and the capital-raising side of digital asset projects. The two agencies would coordinate on overlapping jurisdictions through joint rules intended to prevent duplicative or conflicting requirements for firms registered with both regulators.

For crypto exchanges, brokers and custodians, the immediate significance is not that the rules would change in September. They would not. The importance is that a bill capable of defining the legal structure of the U.S. spot crypto market has moved closer to actual Senate consideration. Today, companies can face different legal interpretations depending on whether a token transaction is viewed as involving a security, commodity or another form of digital asset. The CLARITY Act would replace part of that case-by-case environment with registration categories and statutory rules.
