Polymarket War Bets Raise Insider Trading Concerns After 98% Win Rate Claim

A new investigation into Polymarket war betting has raised sharper concerns about insider information in prediction markets, after data analysts identified nine connected accounts that allegedly made $2.4 million betting almost exclusively on U.S. military operations.

Bubblemaps co-founder and CEO Nicolas Vaiman told 60 Minutes that the linked Polymarket accounts placed more than 80 bets and recorded a 98% win rate. The accounts allegedly won on highly specific markets tied to pivotal moments in the Iran conflict, including the first U.S. strikes, the removal of Iran’s supreme leader, and the announcement of a ceasefire.

The pattern is not being treated as ordinary luck by investigators watching the market. Vaiman said many of the winning wagers were placed when the odds were still low, making the win rate especially difficult to explain through public information alone. Bubblemaps’ findings were shared first with 60 Minutes, which framed the activity as a possible example of insider trading in event contracts.

No named trader behind the nine accounts has been charged in connection with those specific wagers. That distinction matters because the current finding is an analytics-driven allegation based on wallet behavior, account links, timing, odds, and outcomes rather than a completed criminal case.

War Markets Expose Prediction Market Weakness

The case lands at a sensitive time for prediction markets. Platforms such as Polymarket turn real-world events into tradable contracts, with users buying and selling outcomes as prices move. That model can create useful public probability signals, but it also creates a direct financial incentive for anyone with nonpublic information to trade before the wider market catches up.

Military markets are especially vulnerable because the information edge can sit inside government, military, intelligence, contractor, diplomatic, logistics, or family networks. A market asking when a strike, raid, ceasefire, airspace closure, or leadership change will happen is not the same as a normal crypto price bet. It can be influenced by classified planning, operational schedules, restricted briefings, or sensitive diplomatic channels.

That risk has already moved beyond theory. A 60 Minutes transcript referenced the case of U.S. Army Master Sgt. Gannon Ken Van Dyke, who has pleaded not guilty after being charged over alleged wagers tied to a U.S. military operation involving Venezuelan President Nicolás Maduro. Prosecutors allege he used classified information to place bets and made more than $400,000.

Polymarket told 60 Minutes that when its systems identify suspicious activity, the company acts through referrals to law enforcement and cooperation with investigations. The company also said insider trading is not welcome on the platform and that those who attempt it will be identified.

Transparency Helps, But It Does Not Solve The Risk

Polymarket’s blockchain-based structure creates a strange market-integrity split. Trades can be publicly analyzed, which allows firms like Bubblemaps to cluster wallets, trace flows, and identify suspicious patterns. The traders behind those wallets can still remain difficult to identify without exchange records, KYC links, device data, subpoenas, or law-enforcement cooperation.

That gap is why prediction markets are becoming a larger regulatory and market-structure story. The CFTC previously ordered Polymarket to pay a $1.4 million civil penalty in 2022 and wind down noncompliant markets after finding that the platform offered event-based binary options without proper registration. The broader category has since grown far beyond niche crypto speculation, with prediction markets now covering politics, macro events, sports, crypto outcomes, legal rulings, and geopolitical risk.

The latest Bubblemaps findings also fit a wider profit concentration problem. Recent Polymarket profit data already showed how a small group of sophisticated traders can capture a large share of platform gains, leaving casual users exposed to faster, better-informed, and better-capitalized participants.

The military-betting allegations now put a sharper question in front of prediction markets: whether transparent onchain trading can still produce credible prices when some participants may be trading on restricted information. The next concrete test is whether wallet clustering, platform surveillance, exchange records, and law-enforcement referrals can connect suspicious accounts to real identities without turning event markets into a venue for monetizing classified or sensitive government information.
