Prediction market odds on the CLARITY Act passing before 2027 collapsed from nearly 75% to 50% in a single week.
Traders are pricing in a compressed Senate calendar, unresolved yield-bearing stablecoin disputes, and the kind of banking lobby friction that has repeatedly stalled stablecoin regulation at the floor stage. The window for passage before August now sits at 37%-and before July, just 14%.

What the Prediction Market Data Actually Shows for The CLARITY Act
The Kalshi and Polymarket signals are telling different stories right now, and the divergence matters. Kalshi’s pre-2027 contract cratered to 50%; Polymarket’s 2026 passage contract is currently trading at 60%-up 16% over the prior month-suggesting retail prediction market participants are structurally more optimistic than the Kalshi positioning implies.
Galaxy Digital head of research Alex Thorn had already flagged this range, putting 2026 passage odds at roughly 50-50 in April and citing five sequential procedural hurdles: Banking Committee markup, a 60-vote Senate floor win, reconciliation with a Senate Agriculture companion, reconciliation with a House version, and a presidential signature.
The committee markup cleared on May 14th – Senate Banking passed the CLARITY Act 15 to 9, but that clears only one of five gates.
TD Cowen’s Jaret Seiberg is considerably more skeptical, telling clients he sees the bill’s chances at one-in-three for this Congress.
His argument: any serious fight over yield-bearing stablecoins and bank versus non-bank issuer parity could push final passage into the next administration entirely. That gap between Seiberg’s 33% and Galaxy’s 70-75% conditional estimate is where traders are currently trying to find equilibrium.
Senate Gridlock and the Yield-Bearing Stablecoin Fault Line
The core legislative friction driving this repricing is the yield-bearing stablecoin dispute, and it is not a peripheral issue.
The banking lobby is actively pushing for a blanket ban on stablecoin yield, framing it as a systemic risk to deposit-funded banking models.
JPMorgan Chase CFO Jeremy Barnum echoed that line publicly, emphasizing the risks of allowing stablecoins like USDC to generate yield for holders.
This is the same fault line that delayed the Senate Banking Committee markup by roughly four months, consideration was originally slated for January before senators needed more runway to negotiate the yield provisions.
That delay is now being read by traders as a structural signal: if yield language could slip the timeline by four months at committee, it can slip a floor vote past the August recess entirely.
Analysts tracking the Senate floor calendar note only 9 to 10 usable weeks remain in 2026 once August and pre-election breaks are excluded.
For crypto legislation as technically contested as the CLARITY Act, that is an extremely tight window – and it explains why the short-dated Kalshi contracts (before July, before August) have collapsed so sharply even as the longer-dated 2026 Polymarket contract holds above 60%.
Senator Cynthia Lummis, the bill’s sponsor, is pushing back on the pessimism. Her framing: “Wyoming didn’t wait for Washington to figure out digital assets.
We built the framework ourselves. I didn’t come to the U.S. Senate to slow that down, I came here to scale it-and that’s exactly what my bill, the Clarity Act, does.” Polymarket odds ticked up following her remarks, which suggests her floor advocacy is still moving retail contracts at the margin.
