CLARITY bill: Senate vote on September 15, traders give a 14% probability of passage

On September 15, a procedural vote in the U.S. Senate will decide the fate of the cryptocurrency industry.

On September 15, the U.S. Senate will hold a procedural vote that will determine whether the cryptocurrency industry finally gets the regulatory framework it has been seeking for five years, or whether it will not be restarted until at least 2027.

The bill is called the Digital Asset Markets Clarity Act. The forecast market currently sees a 14% chance of becoming law this year, down from a peak of 82% in February. The huge gap between the importance of this bill and the market's confidence in it is the key to the problem. Here is the actual situation of the bill.

What did the Clarification Act do?

Politics aside, the bill answers a core question: Who regulates cryptocurrencies in the United States-the Securities and Exchange Commission (SEC) or the Commodity Futures Trading Commission (CFTC)?

The current answer is "manage both, but in an unpredictable manner and mainly through law enforcement action." The Clarification Act will replace this status quo with a clear division of labor. The CFTC will gain exclusive jurisdiction over digital goods, covering spot transactions in assets such as Bitcoin. The SEC retains jurisdiction over digital securities and issuers. The bill also sets out criteria for determining when an asset is decentralized enough to no longer be considered a security but should be considered a commodity.

The Senate version introduced a term more important than the literal meaning: "ancillary assets." It covers a type of network token whose value depends on the entrepreneurial or management efforts of the originator or related person. These assets will be subject to tailor-made SEC disclosure requirements rather than a complete securities regulatory regime. If you have ever wondered what category your favorite altcoin belongs to, then it is this definition that determines where it belongs.

Around the core, the following provisions will truly change day-to-day operations:

Intermediary registration: Exchanges, brokers and dealers will face registration requirements and operating standards, as well as consumer protection, anti-money laundering and information disclosure obligations.

Custody benefits: Customer assets held in custody are not counted in the assets or liabilities of the custodian, which makes cryptocurrency custody consistent with traditional custody processing.

Insider resale restrictions: directly targets early holders 'quietly selling to retail demand.

"DINO" bug fix: Senator Loomis has described a bug that allows platforms to claim to be decentralized while manipulating in the background. The revised bill brings exchanges, DeFi platforms and cryptocurrency ATMs under the jurisdiction of the Bank Secrecy Act and the sanctions framework.

Anti-fraud funding: Approximately US$150 million.

Why did the Clarity Act take so long?

The House passed the bill in July 2025 by a vote of 294 to 134. That was more than a year ago. Subsequently, the bill was shelved. The Senate Banking Committee finally passed the bill by a 15 - 9 vote on May 14, 2026, with all 13 Republicans and two Democrats voting in favor. But even the two Democrats who voted yes said a committee vote did not guarantee support in the plenary session.

The obstruction is not a technical issue, but stems from a clause: morality. Democrats want to strengthen safeguards on conflicts of interest and illicit finance, especially on how much government officials can profit from cryptocurrencies while in office. Elizabeth Warren has repeatedly argued that the draft is not enough given the Trump family's cryptocurrency holdings. Republicans want to build a bipartisan coalition that will bring market certainty with it. Neither side made enough concessions. President Trump convened regulators and exchange executives at the White House on August 19 to urge the Senate to take action. However, this did not break the deadlock in the negotiations.

What will happen on September 15th?

September 15 was not a vote on the bill, but a "end debate" vote on the "motion to proceed", which determines whether to allow debate on the bill to begin. It takes 60 votes to overcome a filibuster. Republicans have enough seats to move forward with the motion, but need the support of about ten Democratic senators. Thun filed a motion to close debate before the Senate adjourned, so the date has been locked. The Senate will resume on September 14.

If the motion to end debate fails, the bill will effectively die in 2026. If the motion passes, the Senate still needs to hold full debate, possible amendment procedures and a final vote on adoption. The Senate version then needs to be reconciled with the House version (likely through a conference committee) before it can be submitted to the president. There is also a scheduling issue. When lawmakers reconvened, there were only 14 working days before the October election recess, and a total of 22 working days by the end of the year. They must also provide funding to the government during this period.

Why does the forecast market only give a 14% probability?

Because 14% is not a bet on the September 15th vote. It is the compound probability of each step occurring one after another in the chain: termination of debate, unanimous approval, coordination with the House, approval of the conference report by both houses, and the president signing a bill that contains provisions restricting his own financial activities. Every step increases the risk. That's why a bill is likely to cross a certain hurdle but is still unlikely to become law in the end. The trajectory itself speaks for itself. The contract peaked at 82% in February, fell to 43% in July after reports of a breakthrough due to ethics issues, then to 32% and then to 16% after the recess came in August and no vote was held. Now, its trading volume has exceeded US$11 million, with a probability of 14%. Polymarket correctly predicted several procedural outcomes of the GENIUS bill weeks ahead of traditional analysts, so this is not a group with a poor track record in congressional scheduling. There is another factor behind this number. If Democrats win the House in November, they are expected to prioritize supervisory investigations over cryptocurrency legislation. This will close the window period rather than reopen it in 2027.

What does this mean for cryptocurrency prices?

The failure of the motion to close the debate on September 15 is unlikely to cause a market meltdown. At a 14% chance, failure is already the basic scenario, which means it has largely been absorbed by the market. Asymmetry is reflected in the other hand: passage will be an accident, and an accident will drive the market. The assets that are most affected by the results are those whose classification is truly ambiguous. Bitcoin is a commodity under any framework anyone proposes. The tokens that would benefit most from a clear definition of ancillary assets are large market cap altcoins that have long been in regulatory gray areas, as well as exchanges and custodians that ultimately gain a path to registration rather than face enforcement risks. Pay attention to the closing debate vote count on September 15, not the price. If ten Democrats defected, the probabilities of all subsequent events would be immediately readjusted.
