Israeli authorities have initiated a formal investigation into suspicious betting activity on the US-based prediction market Polymarket, following a user’s highly accurate forecast of military action against Iran. The probe centers on an account under the name ‘Magamyman,’ which netted approximately $430,000 in gross profits by correctly predicting that the United States would conduct strikes on Iranian targets on February 28th.
According to reports from Israel’s Channel 12 news, this incident marks neither the first nor the most substantial successful wager placed by this particular user regarding events in Iran. The Polymarket platform, which permits betting on diverse outcomes ranging from sporting events to geopolitical conflicts and governmental stability, saw substantial market activity preceding recent hostilities. Israeli financial outlet Globes reported that approximately $529 million in total bets were placed concerning the initiation date of the conflict, with $90 million specifically wagered on February 28th.
The investigation seeks to determine whether the account holder possessed confidential insider information rather than extraordinary luck. This suspicion is amplified by the user’s previous accurate prediction of an Israeli attack on Iran scheduled for October 26, 2024—an operation that Israeli security sources confirm received governmental authorization shortly beforehand.
Concerns about potential insider exploitation of prediction markets extend beyond Israel. US Senator Chris Murphy (D-CT) publicly expressed outrage on social media platform X, declaring it ‘insane this is legal’ and announcing imminent legislation to prohibit such activities, alleging that ‘people around Trump are profiting off war and death.’ These allegations emerge despite the White House’s denial that anyone in former President Trump’s circle was involved in the profitable trades.
The scrutiny intensifies due to the Trump family’s documented connections to Polymarket. Donald Trump Jr. serves as an advisor to the platform, and his venture capital firm has invested millions of dollars into the company. Furthermore, the Trump administration previously terminated two investigations into Polymarket that had been initiated under the Biden administration.
This case echoes a separate February incident in which Israeli military personnel were arrested on suspicion of placing bets based on classified intelligence. The situation underscores growing international apprehension about prediction markets being manipulated by individuals with privileged access to sensitive political and military decisions.
