On September 15, local time, a procedural vote in the U.S. Senate to advance consideration of the Digital Asset Market Clarity Act (CLARITY Act) failed. The bill would define the supervisory roles of the U.S. Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC), as well as trading rules, in cryptoasset markets. According to the official roll call, the vote was 49 in favor, 50 against, and one not voting, short of the 60 votes required. This was not a vote on final passage of the bill. It was a vote on whether to end debate on the motion to proceed to the bill and move to the next stage. Some Republicans also voted no, but according to the Senate's record of proceedings, Thom Tillis cast his vote against it so that he could file a motion to reconsider. Immediately after the result was announced, Tillis filed a motion to reconsider the outcome of the procedural vote.
The Block reported that President Donald Trump's cryptoasset businesses and conflicts of interest involving public officials were key points of contention. According to The Block, Democratic Senator Mark Warner said he opposed advancing consideration of the bill because conflicts of interest surrounding the president's cryptoasset businesses remained unresolved. The outcome blocked further progress on the bill, but did not mean that it had been definitively rejected. The Block reported that another procedural vote could be held if Senate floor time became available.
