Congress Moves Quickly to Regulate Prediction Markets After Insider Trading Scandals
Congress launched bipartisan efforts to regulate online prediction markets after a wave of insider trading scandals.
Why it matters: Legal and compliance teams must track emerging prediction market regulations that could reshape how financial and tech clients engage with these platforms. Proposed laws could limit or ban participation by officials and tighten compliance demands.
- Two bipartisan bills in Congress target insider trading and ban trading by elected officials on prediction platforms.
- Recent scandals include a U.S. Army sergeant allegedly profiting $409,000 on Polymarket using classified information.
- Kalshi fined and suspended individuals—including a MrBeast editor and congressional candidates—for insider betting.
- Industry leaders emphasize the need for trust and strong internal compliance to maintain platform integrity.
Congress took swift action following a string of high-profile insider trading cases tied to online prediction platforms such as Kalshi and Polymarket.
- On April 30, 2026, Senators Kirsten Gillibrand and Dave McCormick introduced the Prediction Market Act of 2026, aiming to ban elected officials from trading and develop a regulatory structure.
- Senators Todd Young and Elissa Slotkin also proposed bipartisan legislation—the Public Integrity in Financial Prediction Markets Act of 2026—which would prohibit federal officials from betting on market contracts using inside information.
Multiple enforcement actions sparked these moves:
- Army Master Sgt. Gannon Ken Van Dyke was charged in April for allegedly generating $409,000 on Polymarket with classified government information (details).
- Kalshi fined MrBeast’s editor Artem Kaptur $20,000 and suspended him for two years for insider trading on video-related bets (story).
- Three congressional candidates received five-year bans for betting on their own elections (AP report).
Senator Todd Young said, “Public service should never be a pathway to personal profit based on insider information.” Kalshi’s enforcement head, Robert DeNault, added, “If people don’t trust [our markets], they’re not going to use them.”
With legal rules being crafted in real time, organizations engaged in prediction markets should prioritize monitoring compliance best practices and watch for new federal restrictions that could impact employee and executive participation.
By the numbers:
- $409,000 — Alleged profit earned by Army Sgt. Gannon Ken Van Dyke through insider trading on Polymarket.
- $20,000 — Fine imposed on Artem Kaptur by Kalshi for insider trading.
- 5 years — Suspension length for congressional candidates caught betting on their own elections.
Yes, but: Details on the final regulatory measures and implementation timelines remain unclear.
What's next: Legal and compliance teams should anticipate additional guidance or legislative updates as Congress advances new prediction market regulations.
