After years of arguing over who should regulate crypto in the United States, the Senate is approaching a vote that could finally settle some of the industry's biggest legal questions.
The Digital Asset Market CLARITY Act faces a critical procedural vote on Tuesday, September 15, with lawmakers deciding whether the sweeping crypto market structure bill can advance toward final passage. The immediate hurdle is high: supporters need at least 60 votes to invoke cloture and move the legislation forward.
Republicans have spent the final days before the vote rewriting the bill in search of enough Democratic support. The latest version incorporates 126 substantive changes requested by Democrats, according to lawmakers involved in the negotiations, touching everything from political ethics to DeFi and stablecoins.
Yet its passage remains uncertain. The Senate has spent months negotiating the legislation, and several of the issues that delayed it earlier this year are still dividing lawmakers, banks and the crypto industry.

What the CLARITY Act Would Actually Change
At the center of the bill is a question crypto companies have been fighting over with Washington for years: when is a digital asset a security, and when is it a commodity?
The CLARITY Act would establish a federal market structure for digital assets and divide regulatory responsibilities between the Securities and Exchange Commission and Commodity Futures Trading Commission.
The legislation would give the CFTC broader authority over spot digital commodity markets while establishing rules for exchanges and other intermediaries. It also creates disclosure requirements for certain digital assets and requires the SEC and CFTC to coordinate on implementing parts of the framework.
For crypto companies, the significance goes beyond which regulator gets jurisdiction. A federal law would make it considerably harder for the rules governing assets, exchanges and token issuers to change every time a new administration appoints different regulators.
That has become particularly relevant even as Washington's regulatory posture toward crypto has shifted. SEC Chair Paul Atkins said this week that he supports congressional passage of market structure legislation, while making clear that the SEC will continue developing its crypto rules even if Congress fails to act.
The Senate Has Already Come Surprisingly Far
The bill arriving on the Senate floor is the product of more than a year of negotiations.
The House passed its version of the CLARITY Act in 2025. This year, the Senate Agriculture Committee advanced complementary market structure legislation designed to give the CFTC authority over digital commodity spot markets.
The Senate Banking Committee subsequently advanced the CLARITY Act in a 15-9 vote, giving the legislation something previous attempts at comprehensive crypto regulation struggled to achieve: bipartisan momentum.
A planned floor push before the August recess was eventually abandoned as lawmakers remained divided over several provisions. The delay pushed the fight into September and gave negotiators another month to rewrite the legislation.
Sen. Cynthia Lummis released updated text ahead of today's vote, adding new provisions covering DeFi protocols, credit unions and the treatment of digital commodity transactions.
DeFi Is Now Part of the Fight
One of the latest changes addresses a difficult question for lawmakers: when should a DeFi application be treated like a financial intermediary?
The revised legislation would require certain non-decentralized DeFi protocols to register with the CFTC and comply with Bank Secrecy Act requirements.
The distinction depends partly on how much control exists behind the protocol. Applications where a person or group can materially alter functionality, censor users or otherwise exercise control may not receive the same treatment as software operating autonomously through predetermined rules.
At the same time, lawmakers have attempted to protect genuinely decentralized software and developers who do not control customer assets.
That distinction could become one of the most consequential parts of the legislation. DeFi protocols collectively handle billions of dollars without necessarily operating through the corporate structures used by Coinbase, Kraken or traditional exchanges.

Stablecoin Yield Is Still Dividing Banks and Crypto
Another fight has little to do with whether Bitcoin is a commodity. Banks are concerned about what happens when stablecoins begin competing directly with deposits.
The GENIUS Act established federal rules for payment stablecoins in 2025, but the broader debate over rewards and yield has continued into the CLARITY negotiations. Banking groups worry that attractive stablecoin incentives could encourage consumers to move deposits out of banks, reducing the funding available for lending.
Crypto companies see the issue differently, arguing that restrictions could protect banks from competition while limiting how stablecoins develop as financial products.
Reuters reported that the latest CLARITY draft includes changes intended to address banking-sector concerns, but opposition has not disappeared.
That leaves lawmakers trying to create crypto market structure rules while simultaneously deciding how aggressively stablecoins should be allowed to compete with the traditional banking system.
Trump’s Crypto Business Became Another Major Obstacle
The politics became even more complicated because President Donald Trump and his family have substantial business interests in crypto.
Democrats have pushed for stronger restrictions preventing presidents, members of Congress and other public officials from profiting from digital assets while in office. The issue became one of the largest barriers to bipartisan support for the bill.
Republicans responded by adding new ethics provisions to the latest text. Reuters reported that the revised legislation incorporates most of a proposal negotiated by Sens. Thom Tillis and Ruben Gallego and includes restrictions involving public officials and crypto holdings.
The proposal also gives state attorneys general a role in enforcing certain conflict-of-interest rules.
Those concessions have not satisfied everyone. Senate Banking Committee Democrats have argued that the legislation still contains major loopholes, citing concerns around investor protection, illicit finance, financial stability and political conflicts of interest.
That disagreement may ultimately determine whether Republicans can reach the 60 votes they need.
Why September 15 Matters
Today's vote is not final passage of the CLARITY Act. It is a procedural vote determining whether the Senate can move forward with the legislation.
But politically, it may be just as important.
The legislative calendar is getting tighter, and failure to reach 60 votes would make another comprehensive crypto push increasingly difficult this year. Reuters reports that even after the latest compromises, it remains unclear whether supporters have enough Democratic votes to advance the bill.
Markets are reflecting that uncertainty. Prediction-market odds for passage have fallen sharply ahead of the vote, while Bitcoin traded around $77,000 Tuesday morning as investors waited for the outcome.
If the Senate does advance CLARITY, the legislation would still have additional steps before becoming law, including resolving differences with the House legislation.
The more important change would be political. After years in which comprehensive crypto legislation repeatedly stalled in Washington, Congress would have demonstrated that a permanent framework dividing authority between the SEC and CFTC is within reach.
If the vote fails, the industry's regulatory future will remain much more dependent on decisions made inside those agencies.
Either way, September 15 has become the biggest test yet of whether America's increasingly crypto-friendly regulatory environment can be turned into federal law.
