Polymarket Investigates Suspected Insider Trading in Israeli Election Bets

According to blockchain records, over 600 digital wallets were created on election day with no prior transaction history, and at least 101 accounts were funded for the first time on that day. The bets rapidly increased in value immediately after television exit polls indicated a stronger performance for the Likud than pre-election polls had suggested. Several traders quickly closed their positions and cashed out over $100,000 in combined profits, while others hold significant unrealized gains. One account, which stands to make nearly $180,000, received a deposit of approximately $40,000 from Tron blockchain wallets previously flagged for malicious activity and sanctions.

Polymarket's internal investigation team is reviewing dozens of these newly created wallets to determine if users had access to non-public information before the exit polls were released. Blockchain analysis firms Polysights and Bubblemaps have also flagged the activity as suspicious and are conducting their own investigations. While the timing and coordination of the transactions have raised concerns about potential insider trading, Polymarket has not yet found definitive proof of insider information being used, noting that the activity could also be the result of fortunate betting or successful independent analysis.
