Polymarket examines suspicious bets placed ahead of the Israeli election

what happened

Polymarket, the prediction market operator, is examining a cluster of timely and lucrative wagers placed on Israel's election this week, Bloomberg News reported on Thursday, with Reuters relaying the story. Hundreds of freshly opened accounts reportedly backed Benjamin Netanyahu staying in office and his Likud party taking the largest number of seats. Those positions turned profitable after exit polls suggested Netanyahu's bloc had outperformed early tallies, and some accounts have already withdrawn more than $100,000.

Polymarket's internal investigators are going through dozens of recently created wallets that traded on the vote. Analytics firms Polysights and Bubblemaps have raised the same concerns and are running their own checks. Neither firm immediately answered requests for comment, and Bubblemaps said its data was current but it has nothing new to add.

why it matters

Prediction markets have drawn growing attention over possible insider trading as volumes climb and platforms including Kalshi report more suspicious activity. The findings remain inconclusive, since separating insider bets from independent research or plain luck is hard. Earlier, in May, Reuters had flagged a sharp rise in suspicious trading on Polymarket.
