Jason Cahill is in the news because Kalshi said it suspended and fined three political candidates for betting on their own races, calling it political insider trading. The company said it has since added safeguards to stop candidates from trading on their own elections. Earlier coverage also placed him among the candidates to watch in the 2026 U.S. House races, but the recent betting issue is the main development.
