Polymarket suspects Kalshi of spying on its NYC offices and staff
Polymarket suspects rival prediction market platform Kalshi may be conducting corporate espionage targeting its New York City offices and employees, the New York Post reported June 3. The claim centers on what Polymarket considers suspicious activity around its headquarters, though the article does not specify what evidence Polymarket has gathered, what form the alleged spying took, or whether any legal action has been filed. The New York Post's article is paywalled beyond the lede. No specific evidence or legal proceedings are described in the available reporting. The suspicions mark an escalation in tensions between two of the most prominent prediction market platforms competing in the U.S. market.
Any proven espionage finding would expose Kalshi to criminal trade-secret charges and civil discovery that could freeze its product roadmap while Polymarket gains leverage in CFTC venue fights. The allegation alone signals that platform rivalry has moved beyond regulatory lobbying to physical security.
