Suspicious Trades Flagged on Kalshi and Polymarket Before Poll Drop
Researchers spotted well-timed bets on two Senate races placed before a major Times/Siena poll was released, raising questions about possible inside information.
Researchers have identified suspicious trading activity on the prediction markets Kalshi and Polymarket that occurred shortly before the release of a New York Times/Siena College poll covering two U.S. Senate races, according to a report by The New York Times.
A single trader appears to have placed well-timed wagers on both platforms in the affected Senate contests. The timing of the bets drew scrutiny from researchers monitoring prediction market activity, who flagged the trades as potentially anomalous given how closely they preceded the poll's publication.
