CLARITY Act Update: Senate Eyes September 15 Vote as House Deadline Looms

The CLARITY Act has hit another pause as the U.S. House cancels two weeks of September sessions. With this, September 15 became the key vote day for the Senate to advance the CLARITY Act process. 

The move has raised concerns that the crypto market-structure bill could be pushed past the November midterm elections.

House Republicans Cut Eight Voting Days

House Republicans have canceled voting sessions for the weeks of September 21 and September 28, removing eight legislative days from the September calendar. Lawmakers are now expected to leave Washington on September 17, creating a tight window for the CLARITY Act.

The House did not say the schedule change was related to the bill. However, the timing could become important if the Senate makes changes to the legislation.

If the Senate passes an amended version, the bill would have to return to the House. Lawmakers would then need to approve the same version before it could reach President Donald Trump for his signature.

That makes the Senate’s September 15 vote especially important.

All Eyes on September 15

The September 15 vote is not the final vote on the CLARITY Act. The Senate is scheduled to vote on cloture for the motion to proceed to H.R. 3633. Supporters need 60 votes to clear this step.

With 53 Republicans, supporters would need at least seven additional Democratic or independent votes if all Republicans back the motion.

If the motion passes, the Senate can begin formally considering the bill, including debate and amendments. A separate 60-vote cloture vote would then be needed to end debate before final passage.

This leaves a narrow window for the CLARITY Act.

Could CLARITY Move to November?

The shortened House schedule has increased the possibility of a post-election vote. As, the House is not expected to return to regular legislative work until after the November 3 midterm elections.

If the bill is delayed until then, lawmakers would have to decide whether to take it up during a lame-duck session.

Prediction markets have already reacted to the latest news, with Polymarket traders putting the odds of the CLARITY Act becoming law in 2026 at around 17%, down from above 20% in late August.

Circle President Heath Tarbert says, “The CLARITY Act is the missing piece.”

He urges Congress to pass the bill, saying it would complete the US digital asset regulatory framework.
