CLARITY Act Jumps to 31% — Is the Market Now Too Optimistic?
Market probability: 31%
ProbGap forecast: 24%
Gap: −7 percentage points
Key event: Senate cloture vote — September 15, 2026
The market has sharply repriced the CLARITY Act higher.
Polymarket now gives the bill roughly a 31% chance of becoming law in 2026, up from around 17% last week following a wave of concessions and a revised Senate draft.
The move makes sense.
Republican negotiators have incorporated 126 substantive changes requested by Democrats, President Trump has accepted key ethics restrictions, and the legislation is heading into a critical Senate procedural vote today.
But ProbGap thinks the market may now have moved slightly too far in the optimistic direction.
The ProbGap view
Our forecast: 24% chance that the CLARITY Act becomes law in 2026.
Market: 31%
ProbGap: 24%
Gap: −7 pp
We still consider failure the clear favorite.
The latest concessions materially improve the bill's chances, but a 31% probability may be pricing in too much progress from a compromise that still has several difficult legislative hurdles ahead.
Why the market jumped
The political situation has changed meaningfully.
Senate Republicans released a revised version of the Digital Asset Market Clarity Act that incorporates 126 substantive Democratic requests, including tighter ethics provisions and expanded enforcement powers for state attorneys general.
President Trump also agreed to major elements of a bipartisan ethics framework, removing one of the largest obstacles to Democratic support.
That matters because Republicans need Democratic votes.
The Senate's cloture threshold is 60 votes. Republicans hold 53 seats, so even if every Republican votes yes, at least seven Democrats or independents must support advancing the bill.
The new concessions make that outcome more plausible than it was a week ago.
The market has reacted accordingly.
Why ProbGap remains below the market
A successful compromise does not mean the legislative path is clear.
First, today's vote is only procedural
A successful cloture vote would allow the Senate to move forward with debate.
It would not mean the CLARITY Act has passed.
The bill would still face amendments, final Senate passage, additional House action and presidential approval before year-end.
That is a substantial chain of events.
Second, opposition has not disappeared
Banking groups remain concerned about provisions involving stablecoin rewards and the possibility that crypto products could draw deposits away from traditional banks.
Some Democrats also remain dissatisfied despite the latest ethics concessions. Reuters reports that it is still unclear whether the revised bill has enough support to reach the required 60 votes.
The negotiations have improved the bill's position.
They have not eliminated the political risk.
Third, the calendar is tight
Even if today's vote succeeds, Congress has a limited legislative window before the midterm campaign period intensifies.
The House has also canceled session weeks later in September, further compressing the timetable.
For a prediction-market contract that requires the bill to become law before December 31, timing matters almost as much as political support.
What changed?
The most important change is that the legislation now looks more genuinely bipartisan than it did several days ago.
The latest text includes stronger ethics provisions, additional state enforcement powers and a series of changes designed specifically to address Democratic objections.
That is enough to justify a higher probability than the market assigned last week.
But the move from roughly 17% to 31% is significant.
A 31% probability implies the entire remaining legislative process succeeds roughly three times out of ten.
We think that is slightly too aggressive given the number of hurdles still remaining.
Why ProbGap is at 24%
Our estimate reflects three competing factors.
First, the concessions are real.
The 126 changes and Trump-backed ethics provisions materially improve the probability of Democratic support.
That is why our forecast is not at the market's previous 17–18% level.
Second, the 60-vote threshold remains a serious obstacle.
Republicans still need Democratic support today, and it remains uncertain whether enough senators are prepared to advance the legislation.
Third, clearing cloture would still leave a difficult legislative path.
Even a successful vote today would not resolve the market.
The Senate, House and president would still need to complete the process before year-end.
Putting those factors together gives us:
ProbGap forecast
CLARITY Act becomes law in 2026: 24%
Does not become law in 2026: 76%
Market probability: 31%
ProbGap: −7 pp
We are not saying the recent market move is unjustified.
We are saying the market may have priced the political breakthrough slightly too aggressively.
What to watch next
Today's Senate cloture vote is the immediate catalyst.
If the bill fails to reach 60 votes, both the market probability and our 24% estimate should fall sharply.
If the bill clears the threshold, the probability should move higher — but passage would still be far from guaranteed.
That makes today's vote particularly useful for ProbGap.
Within hours, we should receive a major new piece of information capable of testing both the market's 31% probability and our 24% forecast.
