CLARITY Act: The Senate Votes September 15, And Traders Give It A 14% Chance

On September 15, the US Senate holds a procedural vote that will decide whether the crypto industry gets the regulatory framework it has been chasing for five years, or whether the whole thing dies until at least 2027.

The bill is the Digital Asset Market Clarity Act. Prediction markets currently price its chance of becoming law this year at 14%, down from a peak of 82% in February. That gap between how important this bill is and how little the market believes in it is the story.

Here is what is actually on the table.

What Does The CLARITY Act Actually Do?

Strip away the politics and the bill answers one question: who regulates crypto in the United States, the SEC or the CFTC?

Right now the answer is "both, unpredictably, through enforcement actions." The CLARITY Act replaces that with a split. The CFTC gets exclusive authority over digital commodities, which covers spot trading of assets like Bitcoin. The SEC keeps authority over digital securities and over issuers. The bill also sets out criteria for when an asset is decentralized enough to stop being treated as a security and start being treated as a commodity.

The Senate version introduced a term that matters more than it sounds: the ancillary asset. That covers a network token whose value depends on the entrepreneurial or managerial efforts of an originator or a related person. Those assets get tailored SEC disclosure requirements rather than the full securities regime. If you have ever wondered which bucket your favourite altcoin lands in, this definition is where it gets decided.

Around that core sit the provisions that will actually change day-to-day operations:

• Registration for intermediaries. Exchanges, brokers and dealers face registration requirements and operational standards, plus consumer protection, AML and disclosure obligations.
• Custody treatment. Customer assets held in custody would not count as assets or liabilities of the custodian, which brings crypto custody in line with how traditional custody has always been treated.
• Insider resale restrictions, aimed squarely at the pattern where early holders quietly exit into retail demand.
• The DINO fix. Senator Lummis has described a loophole that let platforms claim decentralized status while running the show behind the interface. The revised bill pulls exchanges, DeFi platforms and crypto ATMs inside the Bank Secrecy Act and the sanctions framework.
• Roughly $150 million allocated to anti-fraud work.

Why Has The CLARITY Act Taken So Long?

The House passed this bill 294 to 134 in July 2025. That was more than a year ago.

It then sat. The Senate Banking Committee finally advanced it on May 14, 2026 by a vote of 15 to 9, with all 13 Republicans joined by two Democrats. Even those two signalled that a committee vote did not guarantee support on the floor.

The blockage has not been technical. It has been one provision: ethics. Democrats want stronger conflict-of-interest and illicit-finance safeguards, specifically around how much government officials can profit from crypto while in office. Elizabeth Warren has argued repeatedly that the draft falls short given the Trump family's crypto holdings. Republicans want a bipartisan coalition and the market certainty that comes with it. Neither side has moved far enough.

President Trump gathered regulators and exchange executives at the White House on August 19 and pressed the Senate to act. It did not unblock the negotiation.

What Happens On September 15?

September 15 is not a vote on the bill. It is a cloture vote on the motion to proceed, which is the vote on whether to allow debate on the bill to begin. It requires 60 votes to overcome a filibuster. Republicans hold enough seats to bring it forward but need roughly ten Democratic senators to cross over.

Thune filed the cloture motion before the Senate left for recess, which is why the date is locked in. The Senate returns on September 14.

If cloture fails, the bill is effectively dead for 2026. If it passes, the Senate still has to get through floor debate, a possible amendment process and a final passage vote. Then the Senate version has to be reconciled with the House version, most likely through a conference committee, before anything reaches the president.

And here is the calendar problem. When lawmakers reconvene, there are only 14 working days before an October election recess, and 22 in total through the end of the year. They also have to fund the government in that window.

Why Do Prediction Markets Give It Only 14%?

Because 14% is not a bet on the September 15 vote. It is the compound probability of every step in the chain happening in sequence: cloture, floor passage, reconciliation with the House, both chambers approving the conference report, and a presidential signature on a bill that contains restrictions on his own financial activities.

Each link multiplies the risk. That is how a bill can be genuinely likely to clear one hurdle and still be unlikely to become law.

The trajectory tells its own story. The contract peaked at 82% in February, sat at 43% after reports of an ethics breakthrough in July, fell to 32%, then to 16% once the August recess arrived without a vote. It now sits at 14% with more than $11 million traded. Polymarket called several procedural outcomes on the GENIUS Act correctly weeks ahead of traditional analysts, so this is not a crowd with a bad track record on congressional timing.

One more factor sits behind the number. If Democrats take the House in November, they are expected to prioritise oversight investigations over crypto legislation. That closes the window rather than reopening it in 2027.

What Does This Mean For Crypto Prices?

A failed cloture vote on September 15 is unlikely to crash the market on its own. At 14% odds, failure is already the base case, which means it is largely priced in. The asymmetry runs the other way. Passage would be the surprise, and surprises move markets.

The assets with the most riding on the outcome are the ones whose classification is genuinely ambiguous. $Bitcoin is a commodity under any framework anyone has proposed. The tokens that would benefit most from a clear ancillary-asset definition are the large-cap altcoins that have spent years in a regulatory grey zone, along with the exchanges and custodians that would finally get a registration path instead of an enforcement risk.

Watch September 15 for the cloture count, not for the price. If ten Democrats cross over, the odds on everything downstream reprice immediately.
