Kalshi bans Ben Midgley for betting on his own Maine governor race
Kalshi has banned Ben Midgley for three years after the Republican gubernatorial primary runner-up bet on his own Maine governor race on the platform. The penalty adds Midgley to Kalshi's growing list of politically connected traders expelled for self-trading, as debate persists over how to regulate prediction markets and police candidate participation. The platform's enforcement action came without waiting for regulator intervention.
Candidate self-trading now draws automatic platform-level consequences before regulators file. Midgley joins Laurie Buckhout as the second candidate Kalshi has expelled for betting on their own race in under two days. The three-year bar signals that intent and identity matter more than wager size in political market integrity rules.
Rivals Polymarket and ForecastEx must match this detection speed or risk becoming the soft venue regulators single out next. Each new expulsion raises the compliance cost for platforms without comparable surveillance. Kalshi gains enforcement scalps to present to Congress and state attorneys general who attack prediction markets as ungamed.
