Kalshi's Anti-Insider Trading Screen Fails to Stop Campaign Staffers From Betting on Their Own Races

Kalshi's May 2026 screening system, designed to block campaign staff from trading on their own candidates by cross-referencing FEC data against user accounts, has failed. NPR reported July 9 that at least one operative listed in FEC records successfully traded on a race they worked despite the new safeguards. Kalshi's head of enforcement said dozens attempted such trades and were blocked, but the confirmed miss exposes a structural gap in the FEC-matching approach.
