Polymarket probes suspicious trades around Israel election, Bloomberg News reports

OCTOBER 29, 2026 19:10Updated: OCTOBER 29, 2026 19:11 Prediction market operator Polymarket is investigating a string of well-timed and profitable trades on Israel's election this week, according to a Bloomberg News report on Thursday.Shortly before polls closed on Tuesday, hundreds of newly created accounts placed bets on Prime Minister Benjamin Netanyahu retaining his position and his Likud party winning the most seats, according to the report.The report said those trades quickly became profitable- and together some of the accounts already cashed out over $100,000 - after some exit polls showed that Netanyahu’s party had won more seats than early reports suggested.Many wallets have significant gains that have not yet been realized, the report said.Prediction markets face growing scrutiny over potential insider trading, with platforms such as Polymarket and Kalshi reporting a surge in suspicious activity amid a sharp increase in trading volumes. Reuters reported in May that Polymarket had seen a significant uptick in trades flagged as suspicious this year.People and political party activists gather near election campaign posters outside a polling station in the southern Israeli city of Ashkelon during Israel’s general elections, October 27, 2026.
