CFTC Warns: Insider Trading Laws Apply to Prediction Markets

• CFTC Enforcement Director David Miller has officially warned that insider trading laws apply to prediction markets, debunking the myth that these platforms are exempt from such regulations.
• The agency will prioritize cases involving the misappropriation of information or tipping, while avoiding "trivial" prosecutions through the use of prosecutorial discretion.
• The warning comes as prediction market volumes surge, recently exceeding $20 billion in monthly volume according to data from TRM Labs.

Regulatory Stance on Event Contracts

During a panel at New York University on Tuesday, David Miller, who was appointed as the CFTC's chief enforcement director on March 2, clarified the agency's legal interpretation of prediction markets. Miller, a former federal prosecutor, stated that the commission views event contracts not as gaming, but as swaps. This classification brings these instruments directly under the jurisdiction of insider trading laws.

Miller addressed widespread misconceptions circulating in mainstream and social media, asserting that the CFTC is actively monitoring the space. The commission intends to focus its enforcement resources on core areas such as market abuse, money laundering violations, and the illegal use of non-public information to gain an unfair advantage in the market.

Suspicious Activity and National Security

The surge in popularity of prediction markets has been accompanied by several instances of highly profitable, well-timed trades.

• One anonymous trader reportedly earned over $400,000 by betting on the capture of Venezuelan leader Nicolás Maduro.
• Other suspicious transactions occurred ahead of major announcements by Donald Trump.
• Recent trades related to the invasion of Iran and the death of Ayatollah Khamenei have raised significant national security concerns among officials.

Legislative and Industry Response

In response to growing scrutiny, leading platforms Kalshi and Polymarket have implemented new internal rules to combat insider trading. Simultaneously, US lawmakers are moving to codify stricter standards. In late March, the bipartisan Public Integrity in Financial Prediction Markets Act of 2026 was introduced to prevent government officials from trading on inside knowledge. This was joined by the Preventing Real-time Exploitation and Deceptive Insider Congressional Trading Act (PREDICT Act).

Democratic lawmakers have also increased pressure on the CFTC, demanding the agency issue explicit warnings to federal employees against utilizing confidential government information for profit on these platforms.
