Kalshi CEO Tarek Mansour claims insider trading is easier to detect in prediction markets compared to the stock market due to the direct link between information and trades. He cited former Rep. George Santos's alleged insider trading on Kalshi as an example, noting the platform is implementing stricter measures to combat such activity. Lawmakers, including Minnesota Gov. Tim Walz, have criticized prediction markets and proposed bans or restrictions.

Kalshi, a U.S. prediction market platform, is in early-stage IPO discussions after annualized revenue surged to $2 billion, driven by increased trading volumes and a $1 billion Series F funding round at a $22 billion valuation. The company dominates 90% of the U.S. market and plans institutional expansion ahead of a potential 2027–2028 IPO.

Kalshi, a prediction market led by CEO Tarek Mansour, is implementing new measures to prevent insider trading, including employment verification for users. The company also introduced risk scoring for markets and enhanced whistleblower tools. These steps come amid scrutiny from lawmakers and a CFTC lawsuit against Minnesota's proposed ban on prediction markets.

Kalshi launched America’s first regulated Bitcoin perpetual futures, approved by the CFTC on May 29, 2026. The product features no expiration date and marks Kalshi’s expansion from prediction markets to derivatives. Offshore perpetual futures volume reached $92.9 trillion in 2025, prompting U.S. regulatory action to retain capital.

House Oversight and Government Reform Committee Chair James Comer has launched an investigation into prediction market platforms Kalshi and Polymarket regarding potential insider trading using nonpublic or classified information. Comer sent letters to both platforms' CEOs seeking details about their operations and user activities.

The Senate has passed legislation to prevent senators and their staff from betting on prediction markets, aiming to increase faith in the institution. The move was pushed by Senator Bernie Moreno and supported by companies like Polymarket and Kalshi. This change comes as lawmakers have tried to police themselves with bans on stock trading while in office.

Kalshi is implementing new tools to prevent minors from trading on its prediction market platform, including facial recognition technology and two-factor authentication. The company is resisting calls to block ages 18-20 from trading. Kalshi's efforts come amid growing concerns about young people engaging in harmful behavior on sportsbooks and prediction markets.

Kalshi CEO Tarek Mansour will speak at Bitcoin 2026 in Las Vegas, discussing prediction markets and Bitcoin's role in regulated financial infrastructure.
