Polymarket has investigated 'dozens' of election-related cases

Polymarket has investigated 'dozens' of election-related bets and referred at least two cases to the CFTC for potential insider trading and manipulation. The company's head of investigations, Shana Bautista, says a team of 16 and a new election surveillance system are actively monitoring bets ahead of the Nov. 3 midterms, receiving hundreds of alerts daily. Campaign staffers have been caught making 'thousands' betting on their own candidates using insider polling information, prompting Polymarket and rival Kalshi to implement detection systems and enforcement measures.
