Senate Republicans Drop Revised CLARITY Act Ahead of September 15 Cloture Vote

Senate Republicans released an updated version of the Digital Asset Market Clarity Act as a procedural vote that needs 60 senators approaches next week.

Key takeaways

• Senate Republicans released a revised CLARITY Act text ahead of a September 15 cloture vote on the motion to proceed, a 60-vote procedural hurdle the bill must clear before any floor debate begins.
• The current text includes self-custody wallet protections and a non-custodial software developer safe harbor, provisions that would place a statutory floor under rights the DOJ's Samourai prosecution tested in court.
• Passage odds are long: Polymarket puts 2026 passage at 17%, Galaxy Research has estimated it in the low double digits. A failed cloture vote does not produce stasis, it hands enforcement back to agencies operating without new statutory constraints.

Senate Republicans unveiled the text of the Digital Asset Market Clarity Act (H.R. 3633) ahead of a September 15 cloture vote, first reported by The Block. The move follows a 616-page merged text dropped July 22 by Sen. Tim Scott (R-SC), Sen. Cynthia Lummis (R-WY), and Sen. Thom Tillis (R-NC) combining the Senate Banking and Agriculture Committee versions of the bill.

The September 15 vote is a cloture vote on the motion to proceed, not final passage. At full Republican support (52 votes), the bill still needs 8 Democrats to clear the 60-vote threshold. The Senate returns from recess September 14.

What the Bill Actually Contains

The current text carries two provisions that matter most to Bitcoin holders and builders. First, self-custody wallet protections derived from Keep Your Coins Act language, which would give individuals a statutory right to use non-custodial wallets. Second, a safe harbor for non-custodial software developers against money-transmitter liability, the same legal theory the DOJ used to prosecute Samourai Wallet developers.

The ethics provisions targeting federal officials' crypto holdings sunset January 20, 2029, are not retroactive, and route enforcement exclusively through the Attorney General, not state AGs or private plaintiffs.

Three sticking points remain unresolved: the ethics rules (specifically whether they adequately address Trump's crypto income), the non-custodial developer liability provision, and a stablecoin yield clause. Seven Democratic senators, Alsobrooks, Booker, Cortez Masto, Gallego, Hickenlooper, Warner, and Warnock, said on July 22 the merged text fell short. Sen. Ruben Gallego called the ethics language "not a serious proposal." No confirmed signals of movement from any of them have emerged since the revision dropped.

The bill passed the House on July 17, 2025 by a 294-134 vote and cleared the Senate Banking Committee on May 14, 2026 by a 15-9 margin. White House crypto czar David Sacks has urged the Senate to pass the bill by end of September.

The Stakes on the Floor

The procedural framing around September 15 obscures what's actually at risk. If cloture passes, the bill moves to a full floor debate and amendment process, and that's where the developer safe harbor and self-custody protections become tradeable chips. Any Democratic amendment conditioning a yes vote on weakening the developer liability provision, or any Republican capitulation to banking-lobby pressure to tighten custody rules, erodes the bill's value to the people it most directly affects.

Polymarket's CLARITY Act passage odds have fallen from 82% in February to 17% as of September 10. Galaxy Research has pegged its estimate in the low double digits. The math is straightforward: 52 Republican votes plus 7 Democratic senators who publicly said no equals a bill that dies on the floor without a shift.

Those signals matter because they define the alternative: not a regulatory pause, but active agency rulemaking with no statutory floor under self-custody or developer liability.

A dead CLARITY Act does not produce a neutral outcome. The DOJ's Samourai prosecution, FinCEN's self-custody rulemaking ambitions, and whatever posture the SEC takes on unregistered digital assets all continue on their current trajectories, unrestrained by statute. The enforcement-first regime doesn't wait.

What to Watch

The operative question for September 15 is not whether the bill passes, it almost certainly won't clear the full process in one vote. The question is whether the self-custody and developer safe harbor provisions survive whatever floor amendments Democrats demand as the price of cloture. If those provisions get traded away in ethics horse-trading, the bill that emerges is a framework for surveilled participation. If they survive intact, it's a meaningful statutory protection regardless of the broader "crypto" packaging around it. The Senate floor schedule can shift; check Senate.gov the morning of September 15 for any timing changes.

Update, September 10, 2026

Lummis went on record detailing that the revised CLARITY Act text incorporates over 100 Democrat-driven changes, including 33 edits in Title I alone, 23 new illicit finance sections, and 30 additional CFTC provisions, framing the concessions as evidence that the holdouts are moving the goalposts.

Among the specific revisions: language specifying when DeFi protocols must register with the CFTC and limiting DeFi provisions to spot and cash transactions, added in direct response to concerns from Native American tribes over prediction markets.

On the market side, Polymarket's year-end passage contract ticked up modestly after the news broke, moving from 16% earlier in the day to 19% by mid-afternoon on September 10.

Even with roughly 100 changes absorbed into the draft, it remains unclear whether those compromises are enough to move the eight Democratic senators Republicans need.

The congressional session clock adds urgency beyond the September 15 procedural vote: because sessions run on a two-year cycle, a bill that dies this session must be reintroduced from scratch, a reset that, combined with the 2026 midterms and the 2028 presidential cycle, makes this window the most viable runway the bill is likely to see. Lummis is pushing to close a deal before year-end. The 100 changes are a sign of active negotiation, not finished business.

Update, September 14, 2026

Senate Republicans released what they are calling their "last, best and final" offer to Democrats late Sunday, a 635-page substitute that breaks the ethics logjam by bringing Trump on board. Trump agreed to about 80% of an ethics counterproposal from Senators Thom Tillis and Ruben Gallego, per a senior Republican aide who spoke to the Associated Press.

State attorneys general will be able to enforce the ethics rules, a concession the White House had previously rejected because it exposes the president to prosecutors he does not appoint.

Under the revised text, covered federal officials and their spouses would be required to divest what the sponsors described as "substantial" or "significant" crypto-related financial interests, or place them in a qualified blind trust. That state AG enforcement power is the sharper give: Lummis had previously said "absolutely not" to allowing state AGs to sue federal elected officials over digital-asset matters, making Sunday's reversal notable.

Lummis, Scott, and Boozman released the final text, saying it incorporates 126 substantive changes Democrats sought.

The text also contains changes to the sections on the Blockchain Regulatory Certainty Act, stablecoin yield, and the Agriculture title.

The Agriculture Committee provisions add guardrails on affiliate trading and conflicts of interest, clarify how state consumer protection laws apply, and protect software developers without altering derivatives regulation or existing CFTC authority. The text also gives the Treasury Secretary new authority to prevent deposit flight tied to payment stablecoins, which the sponsors describe as a circuit breaker protecting community banks.

The market reaction was immediate. Polymarket currently gives the CLARITY Act a 30% chance of becoming law in 2026, while Kalshi puts the probability at 37%, though both remain well below their February highs.

The current probability is up from roughly 12% in early September but remains well below the 82% recorded in February, before Trump's crypto-related disclosures intensified the ethics dispute. The arithmetic on the floor has not changed: Republicans hold 53 seats and need at least seven Democrats, and Gallego and Tillis, the senators who drove the ethics push, had not publicly confirmed the concessions are enough to flip their votes by late Sunday evening.

The calendar is compressing fast. Cloture would only begin debate, as amendments, final passage, and House action on the Senate substitute would still have to fit into a few remaining session weeks, with a state work period beginning October 5 and Election Day on November 3. House leaders also canceled the weeks of September 21 and 28, shrinking the window further.

The cloture vote is scheduled for 2:15 p.m. ET on September 15 and requires 60 votes; failure could delay the bill beyond the 2026 midterms. Stacked directly behind it on Wednesday is an FOMC meeting where Kalshi traders price a 79% probability of a 25-basis-point hike, meaning the policy and macro backdrop for Bitcoin land on back-to-back days. The developer safe harbor and self-custody protections remain in the text. Whether they survive the amendment process that follows a successful cloture vote is the next fight.

Update, September 15, 2026

The brief momentum from Sunday's "last, best and final" offer evaporated inside 24 hours. Polymarket's live contract showed an 18% chance at 8 p.m. EDT on September 14, carrying $17.19 million in cumulative volume, a single-session round trip from roughly 34% earlier that day and 82% in February. The driver of the collapse was the banking lobby. Eight banking trade groups wrote to Senate Majority Leader John Thune and Democratic Leader Charles Schumer on September 14 demanding tighter stablecoin restrictions, arguing the final language leaves open pathways for exchanges to offer interest-like rewards that could pull deposits from banks. The specific flashpoint was the deposit-flight circuit breaker that Treasury Secretary Scott Bessent championed as the administration's concession to community banks, and the trade groups rejected it, writing that a mechanism activating only after substantial outflows "is not a safeguard at all." The coalition letter includes the American Bankers Association, Bank Policy Institute, Independent Community Bankers of America, and National Bankers Association, among others.

The vote itself confirmed the arithmetic problem was never solved. The CLARITY Act's chances of clearing the key Senate hurdle faded Tuesday as Republicans rejected a counteroffer from Democrats, leaving the two sides far apart just hours before the procedural vote.

The bill failed to secure the 60 votes needed to advance, and Fox Business reporter Eleanor Terrett wrote that "one industry leader just texted me: 'It died.'" Negotiations ran to the final hours, with disagreements over ethics clauses driving the impasse, and Democrats insisting on further revisions until the bitter end.

Markets priced the outcome in real time. Bitcoin slipped back to $76,000 and crypto-related names like Circle, Bullish, and Coinbase added to earlier losses.

The failure essentially ends market structure legislative work in the Senate for 2026 and is a major blow to the crypto industry, which has invested years and hundreds of millions of dollars into trying to support its interests.

Polymarket bettors put the chance of the CLARITY Act becoming law in 2026 at just 14% Tuesday morning, down from around 30% after the Sunday substitute dropped.

The developer safe harbor and self-custody protections that matter most to Bitcoin builders were never what the banks were fighting over. They were collateral damage in a deposit-base turf war, and the circuit-breaker dispute became the live evidence of that dynamic heading into today's vote. A failed cloture vote does not produce stasis. It returns enforcement to agencies operating without new statutory constraints on self-custody or developer liability, and the banking groups' letter is now the template for the next redline. Because sessions run on a two-year cycle, the bill must be reintroduced from scratch in the next Congress, a reset that, combined with the 2026 midterms and the 2028 presidential cycle, makes this the most viable runway the bill was likely to see for years.
