Kalshi cracks down on insider trading as Trump family looks to increase prediction market presence

Washington, DC is a hub of information that can influence market movements. Government officials often have insight into upcoming announcements, policy changes, and which officials will attend significant events. Prediction markets are listing contracts based on political decisions and government activities, which makes this information directly tradable.

Kalshi, one of the largest platforms in the industry, has developed advanced surveillance systems to detect suspicious trading. The company has been actively referring suspected misconduct to federal authorities, as being federally regulated prohibits market manipulation and insider trading. Kalshi requires users to complete identity verification and monitors activity for potential violations.

Earlier this year, Kalshi flagged trades by former Congressman George Santos related to markets tied to the State of the Union address, investigating and referring the matter to the Commodity Futures Trading Commission. Similarly, Gabriel Perez, a former White House teleprompter operator, is under investigation for allegedly using advanced knowledge of Trump’s prepared remarks to trade on Kalshi markets.

A study by Columbia Law professor Joshua Mitts and University of Haifa professor of law Moran Ofir found that bets on prediction markets achieved a nearly 70% win rate, resulting in $143 million in profit. Despite the prohibition of insider trading, the Trump family is becoming involved in the prediction market business. President Donald Trump’s media company, Trump Media & Technology Group, is creating TruthPredict, a platform for trading contracts tied to major events and milestones.

They also launched Truth API, a premium service granting Wall Street rapid access to Trump’s posts on Truth Social, potentially allowing traders to react to market-moving information before it's publicly available. The combination of these developments creates an unusual financial ecosystem around the presidency, with Trump’s public statements potentially influencing markets.

Donald Trump Jr., who is a paid strategic advisor to Kalshi and has invested in rival prediction market Polymarket, is deeply connected to the prediction market industry while his father develops a competing platform. However, there is no evidence that Trump Jr. has used privileged government information to trade on these platforms.
