Polymarket priced crypto market-structure law at 31% before CLARITY vote

Minutes before this article was published on September 14, 2026, the Yes price in a Polymarket contract on US crypto market-structure legislation becoming law in 2026 stood at 31%, according to the platform’s price history. The contract’s rules included the Digital Asset Market CLARITY Act as an example, but also allowed other qualifying legislation. The 31% figure was not a price for the CLARITY Act alone.

The price was a historical market quote, not an official forecast. The price history does not show why traders changed their positions, so it cannot establish that Senate revisions caused the move.

What Senate Republicans released

On September 10, Sen. Cynthia Lummis published updated CLARITY Act text. She said it incorporated more than 114 provisions requested by Democratic colleagues. Her release described provisions on when non-decentralized finance protocols would register with the Commodity Futures Trading Commission and clarified that the bill’s decentralized-finance provisions addressed spot and cash digital-commodity transactions. These are her account of the draft’s changes, not evidence that they drove the Polymarket price.

What happened in Congress

The House passed H.R. 3633 by 294 to 134 in July 2025. The Senate Banking Committee advanced it by 15 to 9 in May 2026. On September 15, after the market observation above, the Senate rejected a motion to proceed to the bill by 49 to 50. That was a failed procedural vote, not a final vote on the bill or a resolution of the broader Polymarket contract.

The contract covers enactment by December 31, 2026, of legislation that establishes a comprehensive digital-asset framework, divides federal oversight, and classifies digital assets. It is broader than any one bill. Its September 14 price should be read as a dated snapshot, not the current price or a measured probability of passage.
