Congress Moves to Ban Insider Trading on Prediction Markets After 1,200% Maduro Bet

A single trader’s $400,000 windfall on the capture of Venezuelan President Nicolás Maduro has triggered immediate legislative action in Washington. U.S. Rep. Ritchie Torres (D-N.Y.) is set to introduce the Public Integrity in Financial Prediction Markets Act of 2026, a bill designed to close the regulatory gap allowing federal officials to profit from non-public government intelligence on platforms like Polymarket.

The 1,200% Trade That Alerted Congress

Hours before President Trump announced the capture of Maduro by U.S. forces, a newly created Polymarket account identified as “Burdensome-Mix” aggressively bought “Yes” shares on the market for Maduro’s ouster. The account, less than a week old, deployed approximately $32,500 when the implied probability of the event was roughly 7% (7 cents per share).

Following the overnight raid in Caracas, the contract resolved to $1. The position netted over $400,000 in profit, a 1,200% return in under 24 hours. The timing and specificity of the wager, placed while the operation was likely underway but public knowledge was non-existent, sparked allegations of insider knowledge.

A newly created Polymarket account invested over $30,000 yesterday in Maduro’s exit. The US then took Maduro into custody overnight, and the trader profited $400,000 in less than 24 hours. Insider trading is not only allowed on prediction markets; it’s encouraged. Joe Pompliano (@JoePompliano)

Extending the STOCK Act

The proposed legislation extends the principles of the STOCK Act—which bans insider trading of equities by Congress members—to prediction markets. According to reports from The Block and Punchbowl News, the bill prohibits federal elected officials, appointees, and executive branch employees from trading contracts tied to government actions.

The urgency stems from the sector’s explosive growth. Prediction markets recorded over $44 billion in trading volume in 2025, moving from niche experiments to liquid venues capable of absorbing five-figure bets on geopolitical outcomes without slippage.

The Regulatory Gap

While U.S. regulated exchange Kalshi stated its rulebook already prohibits trading on material non-public information, offshore platforms like Polymarket operate in a gray area. They technically block U.S. users but remain accessible via VPNs, and their decentralized nature complicates enforcement.

The Torres bill targets the individuals rather than the platforms, aiming to criminalize the act of leveraging state secrets for betting profits regardless of the venue.
