Clarity Act (H.R.3633) signed into law in 2026?

TL;DR

The forecast is 13.3% Probability of Yes and 86.7% Probability of No as of October 6, 2026. The central outcome is that H.R.3633 does not complete enactment by December 31, 2026, at 11:59 PM ET. The decisive obstacle is an unresolved Senate bargain on a short calendar, not the President’s willingness to sign an acceptable bill.

Context

The House has passed H.R.3633, but the Senate has not advanced it to consideration. Its September 15 procedural vote failed, and the bill remained pending on the October 5 calendar (Senate roll call; October 5 calendar). Negotiators still have a route back. They do not yet have a publicly verified agreement, sufficient coalition, or commitment to another vote.

The event is narrower than progress on cryptocurrency regulation. Under the forecast’s interpretation, H.R.3633 itself, potentially amended, must pass both chambers in identical form and receive the President’s signature before the deadline. Agency rules, enactment of selected provisions through another bill, or a signature in January do not satisfy that interpretation. The bill’s official tracker is the primary resolution source (Congress.gov).

Evidence

The historical backbone argues against both extremes: failed cloture is not terminal, but discretionary policy bills should not be treated like must-pass funding legislation. A historical review of House-passed bills and joint resolutions that later failed Senate motion-to-proceed cloture covered the 110th through 119th Congresses. It identified 39 episodes, including three pending cases. Among 36 resolved episodes, 15 became law under the same bill number in the same calendar year. Funding and deadline-driven bills dominated that result. A narrower discretionary-policy group contained 12 resolved episodes and only one same-year enactment (GovInfo bill-status records).

Those counts are context, not a precise base rate for CLARITY. The bills differ, the classification involves judgment, and action-text matching can miss failures involving companion measures. The useful lesson is that urgency changes the odds of a rescue. A bill without an unavoidable deadline faces a harder path than legislation needed to keep the government operating.

The strongest favorable analogy is the GENIUS Act. Its initial motion-to-proceed cloture attempt failed 48–49 on May 8, 2025. Renewed cloture succeeded 66–32 on May 19, Senate passage followed 68–30 on June 17, and signature came on July 18. That was 71 days from the initial defeat to enactment (initial proceedings and subsequent chronology; cloture history). This establishes that a crypto bill can recover from a failed opening vote. It does not establish that recovery is the default. GENIUS had more calendar remaining and a rapid, documented turnaround.

Other analogues show the downside. H.R.7024’s bipartisan tax package failed motion-to-proceed cloture 48–44 on August 1, 2024, illustrating a late-cycle economic-policy stall (Senate roll call). H.R.847, the Zadroga legislation, failed that procedural vote 57–42 on December 9, 2010, then became law on January 2, 2011. Its rescue still missed a December 31 signature deadline (Zadroga vote and chronology). For this market, eventual success and timely success are different outcomes.

CLARITY’s own progression contains real strengths. The House passed it 294–134 on July 17, 2025, with 216 Republicans and 78 Democrats voting yes. The Senate Banking Committee advanced it 15–9 on May 14, 2026 (House Clerk; committee announcement). These results show developed legislation and broad historical House support. They do not establish approval of a later Senate compromise.

The decisive floor test was weaker. On September 15, 2026, cloture on the motion to proceed failed 49–50, with one senator absent. All affirmative votes were Republican. Collins, Hawley, Moran and Tillis voted no; Coons did not vote (official roll call). Tillis’s nay enabled reconsideration, which he subsequently requested. That preserves a parliamentary option rather than signaling substantive opposition (Senate Press Gallery).

The potential Democratic bloc matters, but its limits matter too. Gillibrand, Alsobrooks, Booker, Cortez Masto, Gallego, Warner and Warnock reaffirmed their commitment to bipartisan passage on September 16. They did not endorse an agreed replacement or promise votes (joint statement). Restoring Tillis and adding all seven to the recorded affirmative side produces 57, not 60. This is arithmetic from the vote, not a whip count. It also assumes every existing supporter stays supportive.

The substantive bargain has several fronts. Republican sponsors published a proposed substitute on September 14 and described 126 substantive changes requested by Democrats. Their release expressly said the substitute would be offered if the Senate advanced the bill. A published draft was not an adopted Senate text or a joint negotiating agreement (sponsors’ release).

Ethics enforcement remained contested. The proposed state-attorney-general route sought relief against the U.S. Attorney General rather than directly against the official, and specified ethics-office opinions or notices could limit that route. Those are proposed legal mechanisms, not enacted law (substitute text). Warner’s explanation of his opposition identified inadequate presidential and senior-official ethics protections despite progress elsewhere (Warner statement). I read this as a dispute over enforceability, not simply the number of concessions.

Banking and enforcement concerns form a separate constraint. Collins called for more examination of potential deposit losses at community banks and credit unions. The banking lobby argued that the proposed Treasury circuit breaker would act only after substantial deposit flight. That is evidence of stakeholder opposition, not neutral proof of the economic effect (Collins statement; American Bankers Association account). Cornyn, despite voting to proceed, sought changes on stablecoin rewards, developer provisions and law-enforcement safeguards before final passage (Congressional Record). A bargain must gain opponents without shedding supporters.

Later reporting preserves hope without confirming a breakthrough. CoinDesk’s September 27 investigation described last-minute bargaining over allowing an ethics-amendment vote, with written details and leadership authorization disputed. That is not a completed enactment compact (CoinDesk investigation). Patrick McHenry’s October 2 commentary identified a lame-duck opportunity, but a former House chairman’s optimism does not reserve Senate floor time (McHenry interview).

The timing constraint is concrete. The October 1 return order schedules legislative business for November 9, with the first vote assigned to permitting. The tentative annual schedule, dated November 21, 2025, excludes October 5–November 6, November 11–13, November 23–27 and December 21–31. That leaves 22 potential weekdays between November 9 and December 18, not 22 guaranteed voting days (return order; tentative schedule). Funding through December 11 creates competing business within that window (funding law). An early compromise leaves time for Senate proceedings, House concurrence and signature. A late compromise leaves much less room for friction.

What's non-obvious

The key distinction is between willingness to negotiate and an executable agreement. Seven interested Democrats are not seven committed votes. Likewise, the affirmative procedural bloc is not an unconditional final-passage coalition. The straightforward rescue arithmetic hides a harder task: simultaneous agreement on ethics, stablecoin rewards and enforcement while retaining existing support.

Regulatory fallback also cuts both ways. Scott urged SEC and CFTC action until Congress legislates, and the CFTC announced an advance notice of proposed rulemaking on October 5. That was an early regulatory step, not final rules or enactment (Scott statement). Yet House chairmen continued to demand statutory certainty after the defeat (House chairmen’s statement). The inference is limited: agency action offers another route to some policy goals, but does not prove legislative abandonment.

Uncertainties

The largest gap is the state of private negotiations. No authenticated complete Democratic counterproposal, agreed redline, reliable current whip count or renewed floor commitment was established through the cutoff. Public silence does not prove that talks have stopped. Jointly endorsed text, named commitments sufficient for advancement and a dated leadership scheduling commitment would close the most important gaps.

The House’s response to a revised Senate package is also unknown. Its earlier majority supports a viable downstream route, but new ethics, banking or enforcement terms can change that coalition. A House leadership commitment to accept the revised text promptly would reduce this uncertainty.

Finally, schedules are amendable and late-session legislation can move quickly. That keeps a rescue possible. But compressed proceedings can also finish too late, use a different legislative vehicle, or leave unresolved bicameral differences. The saved forecast retains that rescue risk while placing most probability on failure to complete the exact qualifying event before the deadline.
