Polymarket Probes Fresh Wallets That Traded Israel Election Before Polls Closed

Polymarket, the crypto-based prediction market, said its internal investigations team is reviewing dozens of newly created wallets that traded on Israel's 27 October 2026 election, according to a Bloomberg report published on 29 October.

Some of the traders reportedly cashed out more than $100,000, per Bloomberg's account as carried by The Jerusalem Post. Bloomberg said the findings are not conclusive. Neither Prime Minister Benjamin Netanyahu's bloc nor the opposition won a clear majority in the vote.

What Polymarket says it is reviewing

Polymarket's own figure is the smallest on the table: dozens of wallets, meaning blockchain addresses that hold and trade funds on the platform. The company's investigators are examining accounts created shortly before the vote that took positions on the outcome and, in some cases, closed them at a profit.

Israel National News reported that hundreds of new accounts bet on Netanyahu and his Likud party shortly before polls closed on Tuesday 27 October. Several accounts had already closed positions at a profit after the exit polls, according to Time News. Polymarket has not published its own account total, so the numbers below should be read by source, not added together.

The figures behind the flags

Outside analysts and newspapers have supplied most of the detail so far. Each number comes from a different party and measures something different.

Polysights, a tracker of Polymarket activity, flagged what it called fresh wallets buying YES on a Likud win, according to iGaming Future. Bloomberg's reporting does not say whether the $100,000 figure is per trader or combined, so it should not be read as a total.

Why the patterns are not proof

Bloomberg stressed that suspicious patterns are not evidence of insider trading. A profitable position taken shortly before a result can come from independent analysis, from reading polling and exit-poll expectations, or from luck. Newly funded wallets also appear on prediction markets around any high-profile event, because users often open accounts only when a market they care about is live.

The distinction matters for operators and regulators. Wallet-level data can show timing, funding and profit, but it cannot show what a trader knew. That gap is why platform investigations, and not blockchain analysis alone, usually decide whether a pattern becomes an integrity case.

Surveillance and the regulatory backdrop

On 27 October, the day of the vote, Polymarket's head of Global Intelligence & Investigations, Shana Bautista, told NPR the company had rolled out a new election surveillance system ahead of the US midterms. Reuters reported in May that Polymarket had seen a significant rise in trades flagged as suspicious this year.

The review lands in a week of heavy attention on the platform. Gamingo covered the Polymarket third-party breach and the resumption of trading on 30 October, a separate event from the election review. The platform is also in the middle of a US regulatory push: the CFTC signed a non-binding memorandum of understanding as the NBA picked Kalshi and Polymarket, and Ohio told gaming licensees to cut ties with prediction markets by 30 October or risk their licenses. The CFTC is the Commodity Futures Trading Commission, the US derivatives regulator.

Election-linked wagering has drawn scrutiny from licensed regulators before. In 2024 the UK Gambling Commission expanded its probe into election date bets, a reminder that timing-based betting on political events is treated as an integrity issue in regulated markets. Monitoring bodies also publish alert counts for sports; see the IBIA's report of 63 suspicious betting alerts in Q1 2025 for how that reporting looks in the licensed sector.

What operators and compliance teams should watch

• Polymarket's findings. The company has not said when its review will conclude or what action it could take against flagged wallets.
• Regulator and law-enforcement statements. No Israeli, CFTC or congressional response to the election trading has been reported so far.
• Surveillance design. Whether the new election system flags first-time wallets with large late positions will shape how platforms and licensed partners approach event-contract monitoring in the US midterms.
