Republican seeks to add Kalshi and Polymarket rules to congressional stock ban
The top Republican on the House Administration Committee is seeking to add restrictions on lawmakers using prediction market platforms to the panel's signature congressional stock-trading ban, according to sources familiar with the effort. The amendment would specifically cover platforms including Kalshi and Polymarket, extending existing prohibitions on trading individual equities to event contracts. The move, reported June 4, reflects growing scrutiny of elected officials participating in prediction markets alongside traditional securities. The House Administration Committee has advanced stock-trading restrictions as a priority in recent sessions, though comprehensive ethics reforms have faced procedural hurdles.
Kalshi and Polymarket face their first explicit congressional targeting through committee amendment language rather than regulator rulemaking. Any enacted ban would create a compliance template that state legislatures could replicate for their own elected officials, pressuring both platforms to build government-account exclusion tools.
