Clarity Act odds: Polymarket Says 5% After the Senate Flop
Clarity Act odds sit at about 5% on Polymarket after the Senate cloture vote failed 49-50 on September 15. Regulators are moving ahead on their own rules anyway.

- Polymarket's "Clarity Act (H.R.3633) signed into law in 2026?" market showed 5% Yes on Monday, with about $23.5 million in total volume.
- On September 15, a Senate cloture vote on the motion to proceed failed 49–50, far short of the 60 votes needed.
- Regulators are moving anyway: the CFTC sent a rulemaking to the White House budget office on September 17, and SEC comments on its Regulation Crypto Assets proposal are due October 20.

Clarity Act odds are basically on life support. Polymarket's market on whether the crypto market-structure bill gets signed into law in 2026 sits at about 5% Yes, three weeks after the Senate failed to even start debate on it. Over the weekend the book woke up with a volume spike, but the price barely moved.
What actually happened
The House passed H.R.3633, the Clarity Act, on July 17, 2025, by 294 to 134. The bill is supposed to sort out which crypto assets the SEC oversees and which the CFTC oversees, plus a long list of details on disclosures and trading. Then it hit the Senate and stalled.
On September 15, the Senate voted on cloture on the motion to proceed. It failed 49 to 50, according to the Senate roll call and reports from crypto.news and law firm Orrick. Every yes vote came from a Republican. Four Republicans voted no: Susan Collins, Josh Hawley, Jerry Moran and Thom Tillis. Orrick notes Tillis's no vote let him enter a motion to reconsider, which keeps a procedural door open. Chris Coons did not vote.
The sticking points, per crypto.news and Orrick, are ethics provisions and the treatment of stablecoin yield. The ethics fight is about what rules should apply to public officials and their crypto dealings. The yield question is about whether stablecoin holders should be able to earn a return, a point where banks and crypto firms have very different interests. Neither one is a small drafting fix.
What Polymarket thinks
The market is Clarity Act signed into law in 2026 on Polymarket, asking "Clarity Act (H.R.3633) signed into law in 2026?" When we checked it on Monday, Yes was at 5%. Total volume was about $23.5 million, and the market has been open since January 11, 2026. It resolves around the start of 2027.
PolyWatch's October 4 radar flagged the market for a volume spike of about 692 times its normal level, on roughly $12,000 of trading. That sounds dramatic, but the dollar amount is small, and the price stayed pinned near 5%. Translation: someone was active, not that the outlook changed.
Clarity Act odds this low make sense when you do the vote math. Even with the best-case outcome for the bill, supporters are counting around 50 votes, and they need 60 to beat a filibuster. Unless several Democrats flip or the bill is rewritten, the clock runs out on 2026.
In the Senate, 50 is a mood. 60 is a law.
The midterm angle
Stand With Crypto, the industry advocacy group, endorsed three Senate candidates on September 30: Jon Husted in Ohio, Ashley Hinson in Iowa and Chris Pappas in New Hampshire. That is a bet on the next Senate, not this one. We broke down the broader fight in Senate 2026 Democrats and 2026 midterms balance.
The midterms create a strange dynamic for Clarity Act odds. Lawmakers rarely pass big, controversial bills right before an election, and a lame-duck session after November is possible but unpredictable. That uncertainty is exactly what a 5% price is trying to capture.
Regulators are not waiting
While Congress stalls, the agencies are writing rules. The CFTC sent a rulemaking, listed as RIN 3038-AF80, to the Office of Information and Regulatory Affairs on September 17. The SEC proposed Regulation Crypto Assets, with comments due October 20. Rules can do part of what the bill would have done, though they are easier to reverse later.

What to do as a reader
If you are tracking Clarity Act odds, watch three signals: any new cloture vote scheduled, a revised bill text that addresses ethics and stablecoin yield, and public statements from Democrats who have not committed. Any of those could move the market more than a weekend volume spike.
If you are a builder, the SEC comment deadline on October 20 is real and open to the public. Commenting is free, and it is one of the few direct ways to shape the rules.
This is not legal or investment advice. Prediction markets are speculative, rules differ by country and a 5% price is not a promise of anything. Read the resolution criteria on the market page before you treat the number as a forecast, and stay skeptical of anyone who says the bill is "definitely passing next week."
Not financial advice. DYOR, ser.
