Senate Bans Senators from Prediction Market Trading
5/1/2026, 2:32:37 PM
Core Event
On April 30, 2026 the Senate unanimously approved an amendment that bars all senators, their staff, and officers from trading on prediction-market platforms Kalshi and Polymarket. The measure was introduced by Republican Senator Bernie Moreno of Ohio and calls on the House, executive branch, and judiciary to adopt similar bans.
Background & Context
The ban follows incidents that heightened concerns about insider trading on prediction markets. Master Sgt. Gannon Ken Van Dyke was arrested on April 23 for allegedly using classified information to bet on the U.S. operation that captured Venezuelan President Nicolás Maduro, winning $410,000. On April 22, Kalshi said it suspended and fined a Senate candidate and two House candidates for trading on their own campaigns. Congressional members urged the CFTC to issue rules preventing insider trading and corruption on prediction markets.
Timeline
- Mar 17, 2026 – Rep. Greg Casar and Sen. Chris Murphy promote the “Bets Off Act.”
- Apr 22, 2026 – Kalshi suspends and fines a Senate candidate and two House candidates.
- Apr 23, 2026 – Master Sgt. Gannon Ken Van Dyke indicted for alleged insider bets on the Maduro capture.
- Apr 30, 2026 – Senate unanimously adopts the prediction-market trading ban.
Official Statements & Responses
Senator Bernie Moreno called the ban a safeguard against speculative activity by officials. Senate Minority Leader Chuck Schumer praised the swift action and urged the House to follow. Kalshi CEO Tarek Mansour noted the platform already blocks congressional members and enforces insider-trading rules. Polymarket said its terms already forbid such conduct and codifying the ban benefits the industry. Democratic lawmakers have asked the CFTC to adopt broader regulations covering insider trading and event contracts.
Criticism & Opposition
Democrats contend that self-regulation is insufficient without a formal CFTC rule and note that the ban applies only to the Senate, leaving a regulatory gap until the House enacts a comparable measure.
Conflicting Reports & Gaps
Reports list the soldier’s profit as “nearly $410,000” and “over $400,000.” Kalshi’s notice does not reveal the exact fines for the three political candidates, and staff-compliance procedures under the new rule are not detailed.
