US Lawmaker Targets Insider Trading in Prediction Markets After $400K Maduro Bet

The U.S. House of Representatives announced on Monday that Rep. Ritchie Torres (D-NY) plans to introduce the Public Integrity in Financial Prediction Markets Act of 2026. The bill would prohibit federal officials from trading prediction-market contracts based on insider information.

The proposal follows a recent case where a newly created account on Polymarket wagered $32,000 on the removal of Venezuelan President Nicolás Maduro. The trade settled within 24 hours, yielding a $400,000 profit after U.S. forces captured Maduro. The rapid and substantial gain raised concerns about potential abuse of nonpublic information.

Torres' legislation would mirror insider trading standards from traditional financial markets and extend them to prediction platforms. The bill also tasks regulators with determining which platforms qualify for oversight and how violations would be enforced.

Why Did This Happen?

The sudden profitability of the Maduro bet drew widespread attention due to its timing and the account's limited prior activity. The contract's settlement occurred hours before official confirmation of Maduro's capture was released to the public.

This event highlights a growing concern among lawmakers about the potential for abuse in real-time forecasting platforms. Prediction markets have expanded into political, economic, and military event forecasting, making them increasingly relevant to public policy and national security.

How Did Markets Respond?

The announcement of new regulatory scrutiny has already begun influencing the prediction market ecosystem. Kalshi, a regulated prediction market operator, stated in a public response that its rules prohibit trading based on material nonpublic information.

Meanwhile, Polymarket, which was at the center of the Maduro trade, confirmed that it identified and fixed a security vulnerability linked to third-party authentication tools. The company assured users that the issue affected only a small number of accounts and that affected parties would be contacted.

What Are Analysts Watching Next?

Industry experts remain divided on the potential impact of the proposed legislation. Some argue that the bill could curb abuse while preserving the utility of prediction markets for forecasting. Others caution that overly broad rules could stifle innovation and reduce market liquidity.

Marin Kazmierczak, co-founder of RedStone, emphasized the importance of trust and transparency in prediction markets. "The real differentiator will be whether platforms can earn credibility by allowing users to verify that outcomes are executed exactly as advertised," he said according to Decrypt.

In addition to regulatory developments, prediction market platforms are exploring new partnerships to expand their reach. Polymarket recently announced a collaboration with real estate data platform Parcl to launch a new category of real estate prediction markets.

With trading volumes exceeding $44 billion in 2025 and more than $6 billion in combined trade volume through December 2025, the prediction market sector is poised for continued growth. However, its future will depend on balancing innovation with accountability as new legal frameworks emerge.
