A Polymarket user placed a nearly $200,000 bet on Nebraska Senator Pete Ricketts’ re-election just one hour before The New York Times/Siena College released a poll showing him in the lead, according to Vanderbilt University researchers. The trader’s profit exceeded $77,000 following the poll release. The New York Times reported that it remains unclear whether the user possessed inside information, but noted similar large bets were placed on other prediction markets, including Kalshi. Brett Goldstein of Vanderbilt’s Institute of National Security stated the pattern is difficult to attribute to random coincidence and warrants further investigation. Polymarket confirmed it has identified the trades and is investigating, while Kalshi declined to comment.
