Polymarket Suspects Kalshi of Bugging Its New York Office and Employees, Launches Investigation

NEW YORK, June 4 (New York Post) — Rapidly expanding prediction market platform Polymarket is probing what it claims is alleged corporate espionage by its rival Kalshi, according to a report from the New York Post. Polymarket allows users to bet on a wide range of events, from sports matches and weather forecasts to even the Iran war, per its offerings. Insiders told the outlet that the New York-based firm, led by 27-year-old CEO Shayne Coplan, has put together an internal "Copycat" dossier documenting around a dozen suspicious cases. These include instances where Kalshi rolled out new products nearly identical to Polymarket’s, with launch timelines that strike Polymarket as highly questionable. Matthew Modabber, Polymarket’s chief marketing officer, confirmed the investigation during a brief phone interview, stating: "These coincidences have popped up way too often. Their copying of our strategy is clearly malicious—they’ve been monitoring every move we make closely."
