Prediction market platform Kalshi has brought aboard former FBI official Tyler Neff to bolster its surveillance operations, responding to growing legislative pressure on prediction markets to address insider trading violations on their platforms.
Neff came on board with Kalshi in early May, based on his LinkedIn announcement. He will work under Robert DeNault, the company’s head of enforcement and legal counsel, as part of the team overseeing all monitoring activities, according to a company spokesperson.
Before joining Kalshi, Neff spent seven years as an intelligence analyst working on white-collar crime cases at the FBI’s New York field office. After his federal law enforcement career, he held positions at the New York Stock Exchange, Wedbush Securities, and Canaccord Genuity.
The company has expanded its surveillance staff throughout this year, bringing in several other executives from major Wall Street firms including Morgan Stanley and Nasdaq.
These personnel additions follow a wave of questionable trading activity across leading prediction market platforms in recent months. Kalshi has examined and reported more than 400 suspicious trades since January began, representing over double the number of trades the company investigated during the entire previous year, according to earlier Reuters reporting from May.
This week, federal prosecutors charged a software engineer at Google with leveraging inside information to manipulate bets related to Google’s most-searched terms on the Polymarket platform.
