The prediction market for comprehensive U.S. crypto market structure legislation saw a significant repricing on Tuesday, April 28, 2026, as traders lowered their expectations for the CLARITY Act becoming law. The implied probability of passage before 2027 dropped a sharp 16.0 percentage points, from 51% to 35%. This broad-based decline across multiple contract deadlines reflects growing pessimism driven by the Senate's failure to meet a key April deadline, a rapidly shrinking legislative calendar, and persistent policy disputes over stablecoins and ethics provisions.

The negative shift was widespread, with three of the five tracked outcomes declining on substantial volume. The "Before August" contract fell 8.0 percentage points to 26%, while the "Before July" contract dropped 11.0 percentage points to 9%. This move away from near- and medium-term passage suggests the market consensus is that the bill is stalled and at increasing risk of failing in the current Congress. The repricing aligns with external analyses that highlight the formidable procedural hurdles and limited time remaining before the 2026 midterm elections consume the legislative agenda [1, 7].

Distribution Analysis

The decline was most pronounced in the longer-dated contracts, indicating a loss of faith not just in a swift passage but in the bill's overall prospects for the year. A minor rise in the "Before June" contract was a low-volume outlier against the overwhelmingly bearish trend.

Outcome Current Prob Change Volume
Before May 1% ~0.0pp 3,532
Before June 2% +3.1pp 3,094
Before July 9% -11.0pp 2,312
Before August 26% -8.0pp 12,163
Before 2027 35% -16.0pp 3,200

Net: 3 of 5 contracts declined on over 17,600 in total volume, shifting the implied probability of passage before 2027 from 51% to 35%.

What's Driving the Shift

The market's repricing appears to be a direct reaction to recent developments that have significantly compressed the timeline for the CLARITY Act.

  • Missed April Deadline: A key catalyst for the drop was the Senate Banking Committee's failure to hold a planned markup hearing for the bill in April [5]. Senator Thom Tillis (R-NC) requested more time to present a compromise on stablecoin yield language to banking groups, pushing the target to mid-May at the earliest [7]. This missed deadline effectively eliminates the original spring timeline that bill supporters had targeted [5].

  • Shrinking Legislative Calendar: The delay intensifies pressure from a rapidly closing legislative window. Senator Bernie Moreno (R-Ohio) recently warned that the bill must pass by the end of May, after which the midterm election calendar will make advancing controversial legislation nearly impossible [8]. Analysis of the Senate schedule suggests as few as 9 or 10 working weeks remain to pass the bill through all its required steps [7].

  • Persistent Policy Hurdles: The long-standing disagreement over whether to permit yield on stablecoin balances remains the primary blocker [7]. This dispute has now been compounded by a new demand from Senator Tillis, who has threatened to vote against the bill unless it includes ethics restrictions limiting how White House and other federal officials can engage with digital assets [9]. This adds a new, complex negotiation to an already stalled process.

Market Context

This sharp downturn in the prediction market aligns with other indicators of the bill's waning momentum. Odds on the decentralized prediction platform Polymarket for the CLARITY Act becoming law in 2026 have fallen to around 44%, down from a high of over 80% earlier in the year [8].

The market's current 35% probability for passage before 2027 is now significantly more pessimistic than an April 22 analysis from Galaxy Digital, which placed the odds at "roughly 50-50, and possibly lower" [1]. The market appears to be pricing in the high probability that the combination of procedural delays and unresolved policy fights will prove insurmountable in the limited time remaining. The bill must still clear five major hurdles: a Senate Banking Committee markup, a 60-vote Senate floor passage, reconciliation with the Senate Agriculture Committee's version, reconciliation with the House-passed bill, and a presidential signature [1, 8].

What to Watch

The market's focus now shifts to May. The immediate event to watch is whether the Senate Banking Committee can schedule and hold a markup hearing. Senator Cynthia Lummis (R-WY) pledged on April 27 that a markup would occur in May, calling it the "last chance" to pass the legislation before 2030 [7]. The release of Senator Tillis's revised compromise text on stablecoin yield will also be a critical signal. Failure to make concrete progress on these fronts in the next two to three weeks could lead to a further decline in the bill's perceived chances of becoming law.
