Congress bill would bar lawmakers from political prediction market trading

Published Jun 22, 2026Updated 75d ago

A new bill introduced in Congress would prohibit lawmakers from trading on political and election outcomes in prediction markets. The legislation arrives as Congress increasingly treats political prediction markets as a serious enough domain to regulate, with the CFTC's existing posture toward event contracts forming part of the backdrop. The move follows a House panel advancing similar language just days earlier, reflecting bipartisan momentum to cordon off elected officials from the growing market for political event contracts. The CFTC has maintained a restrictive posture on election-related contracts dating back to its 2012 block of Nadex, formerly HedgeStreet, from offering such products, and continued that approach through 2024. Analysts have noted that mention markets could represent remaining gaps in CFTC prediction rules as the regulatory framework evolves.

Why this matters?

Kalshi and Polymarket would lose their highest-profile organic user segment if congressional accounts are forced to close. The dual-track House and Senate action accelerates the timeline for both platforms to build compliance systems before a final vote.
