Prediction markets have become one of the fastest growing sectors in finance, but this could end quickly if insider trading becomes an issue. There is tons of money being traded with political contracts, and insider trading amongst campaign staffers has been a problem.
Kalshi says it has increased its efforts to prevent campaign insiders from trading on races they may have inside knowledge of because of consistent issues. The company has introduced new monitoring systems designed to identify individuals connected to political campaigns before they place trades.
Kalshi is Cracking Down
According to Kalshi, dozens of campaign staffers have attempted to trade on elections tied to campaigns they worked on since May. The exchange says those trades were stopped before they could be executed.
The company's latest enforcement initiative relies on publicly available Federal Election Commission filings. Campaign payroll records and contribution reports are compared against Kalshi user information, allowing the platform to flag potential matches before a trade is completed.
"If we're able to identify a potential match, we have markets that are associated with each of the campaigns that are flagged, and those individuals would be prevented from placing trades on those markets," Kalshi Head of Enforcement and Legal Counsel Robert DeNault said.
The move comes as election prediction markets continue attracting attention from regulators and lawmakers ahead of the 2026 midterm elections. Political contracts have become some of the most actively traded markets on prediction exchanges behind sports, so it’s positive to see Kalshi emphasizing this across their brand.
While Kalshi says its screening process has already prevented numerous trades, the company also acknowledges that no compliance program is perfect. Federal campaign filings only capture certain employees, leaving volunteers, consultants, pollsters, legal advisors, subcontractors, and other individuals outside the scope of many public records.
That creates a challenge for every prediction market offering election contracts. Even with expanded monitoring, identifying every person with access to nonpublic campaign information remains difficult.
Nothing is Perfect for Kalshi…Yet
Kalshi says its enforcement efforts extend beyond automated screening. The company continues investigating suspicious activity after trades occur and plans to expand monitoring to additional races.
"You have to be ready to also follow up with investigations where you've detected people who've gotten around systems," DeNault said.
The company also shared broader enforcement statistics that illustrate how much emphasis it’s placing on market integrity. During the first quarter of 2026, Kalshi says it launched more than 150 insider trading investigations, blocked over 100 suspected insider trading attempts, and referred at least 20 cases to law enforcement.
Those numbers highlight how prediction market operators are increasingly acting as their own first line of defense. While the Commodity Futures Trading Commission oversees federally regulated prediction markets, exchanges have largely been responsible for creating and enforcing their own internal compliance standards.
Kalshi believes that responsibility ultimately falls on the platform itself.
"It’s up to us to make rules of the road for our platform, whether Congress does or not," DeNault said. "We've done that here in an expansive way in that we police all campaign individuals, whether they have insider information or not, from placing trades."
The Trade Handle Prediction Markets Take
The broader prediction market industry continues facing questions from lawmakers as participation grows. Congress has introduced multiple bills related to prediction markets this year, while House investigators are also reviewing how exchanges such as Kalshi and Polymarket detect and respond to potential insider trading.
For traders, confidence in market integrity is essential. Election markets are designed to reflect collective expectations, but that process only works if participants believe contracts are trading on public information rather than privileged access.
As prediction markets continue expanding, maintaining that trust will likely remain one of the industry's biggest challenges. Kalshi's latest enforcement efforts suggest the company is investing heavily in protecting that credibility.
