The Republican nominee in a competitive House race in North Carolina was suspended from betting on the trading platform Kalshi on Monday after placing bets on her own contest.
Laurie Buckhout, an Army veteran, purchased less than $1,000 of contracts “related to her own candidacy,” a violation of Kalshi’s prohibition on users making trades with insider information or on future events they could influence. The platform said Ms. Buckhout had cooperated with its inquiry and received a three-year ban from the platform and a fine of nearly $2,600.
Ms. Buckhout, a retired colonel who served in combat in Iraq and worked briefly in the Trump administration last year as the acting assistant secretary of defense for cyber policy, is running in North Carolina’s highly competitive First Congressional District. She expressed remorse on Monday for her betting.
