Kalshi has been the victim of a flurry of insider trading headlines over the past few months. This is to be expected for a new platform in its infancy. Sports betting companies went through the same growing pains when they began spreading throughout the country in 2018.
Prediction markets have expanded rapidly, and they show no signs of slowing down. The one thing that could cannibalize the industry is insider trading, and Kalshi is leading the charge to make sure that doesn't happen.
Kalshi is Taking a Stand on Insider Trading
Deep in Kalshi's Manhattan office, a dozen young men patrol the world of insider trading on the exchange. Robert DeNault, the head of enforcement, leads the group as they do everything they can to maintain fairness on the platform.
According to DeNault, "the integrity of our markets" is what's at stake. He has made it clear that the number one priority for Kalshi is not growth, as you might expect, but rather eliminating insider trading.
Kalshi launched 200 investigations in 2025, and it has already surpassed that number in 2026. While insider trading is a major point of emphasis on traditional stock exchanges, it's much harder to track on Kalshi.
There are thousands of markets covering various topics, and it's difficult to connect insiders to specific trades. For example, if someone is betting on military operations and has a distant connection to the military, they can be hard to locate. DeNault's team is scanning everything they can find on suspicious users, and they're getting much smarter about how they approach this activity.
The Process to End Insider Trading
Kalshi has to do a lot to ensure that integrity is the standard on the app. DeNault revealed the process, stating that Kalshi examines social media, employment history, and any public information available to identify suspicious traders.
Political bets are where their technology shines. The team uses name-match recognition, cross-referencing campaign data lists for salaried staff who aren't allowed to participate on Kalshi. This triggers the alarm for suspicious user activity.
For politics specifically, they've prevented hundreds of insider trading cases. As the platforms grow, the number of cases will rise exponentially, which is why it's so important that their processes are airtight.
Just last month, American special forces soldier Gannon Van Dyke pleaded not guilty to wagering on Polymarket regarding the United States' raid of Venezuelan President Nicolás Maduro.
His case shows there is a demand for insiders to illegally trade on political activity, and it must be stopped before it spreads further. Kalshi is doing an excellent job handling these cases, and they're only going to get better at it.
The Trade Handle Prediction
The best way for prediction markets to grow, outside of their widespread availability, is to prevent insider trading. This has been the focus of Kalshi because of its importance to the industry's future.
Sports betting platforms cannot compete with prediction markets if exchanges get this right. Sports betting platforms aren't widespread like exchanges, and they don't include all the markets in politics, entertainment, crypto, and beyond.
Regulations in the prediction market space are coming in the future, so the best thing Kalshi and other exchanges can do in the meantime is to make sure they're on top of their game in keeping things fair on the platform. Based on the success of DeNault and his team, Kalshi has the tools to make that happen.
