Kalshi has appointed Tyler Neff to its surveillance team as part of a concentrated effort to bolster oversight on the exchange. Neff, who joined the company earlier in May according to a LinkedIn post, will work under Robert DeNault, Kalshi's head of enforcement and legal counsel, and will be a member of the group responsible for the platform's surveillance operations, a company spokeswoman said.
Neff brings experience from both government and financial markets. He served for seven years as an intelligence analyst on a white-collar crime squad at the Federal Bureau of Investigation's New York field office. Following his time at the FBI, his career included roles at the New York Stock Exchange, Wedbush Securities, and Canaccord Genuity.
The hire is one of several moves Kalshi has made this year to beef up its surveillance staff. The company has recruited a number of executives from established Wall Street firms, including Morgan Stanley and Nasdaq, to join its monitoring unit. Those additions are intended to expand the exchange's capacity to detect and investigate irregular trading patterns.
The timing of the hiring push coincides with an uptick in questionable activity across major prediction market platforms. Since the beginning of the year, Kalshi has probed and flagged more than 400 suspicious trades - a total reported earlier in May that is more than double the number of investigations the platform carried out during the entirety of last year. The elevated volume of flagged trades has contributed to increased attention on how prediction markets police insider trading and other integrity risks.
Heightening the scrutiny on the sector, federal prosecutors this week charged a Google software engineer with allegedly using insider information to manipulate bets tied to Google’s most-searched list on another prediction market. That case underscores the legal and enforcement challenges facing exchanges that allow trading on event-based contracts.
Kalshi's expanded surveillance hiring and the appointment of a former FBI analyst signal a broader industry response to recent enforcement developments and a surge in suspicious trading activity. The company spokeswoman provided confirmation of Neff's role and reporting line but declined further comment on the specifics of ongoing investigations.
