Core Event: High-Win Betting Patterns on Polymarket and Kalshi
Data-analysis firm Bubblemaps identified nine anonymous gambling accounts that have won more than $2.4 million across over 80 contracts linked to U.S. military actions. The accounts posted a 98 percent win rate on bets tied to the war with Iran—including predictions on the killing of Supreme Leader Ali Khamenei, the onset of bombardment, and the timing of a ceasefire—as well as on the capture of Venezuelan leader Nicolás Maduro.
Background & Context: Prediction Markets and Prior Controversies
Polymarket and Kalshi are online platforms that allow users to wager on real-world outcomes, from geopolitical events to commodity prices. In March 2024, the White House circulated an internal memo reminding staff that using nonpublic government information for such wagers constitutes a federal offense. Earlier incidents include an Army Master Sgt. Gannon Ken Van Dyke’s indictment for allegedly using a VPN to bet on Maduro’s capture, resulting in a $400,000 profit from a $34,000 stake.

Official Statements & Responses: Government and Platform Reactions
The White House memo warned that “misuse of nonpublic information … is a very serious offense and will not be tolerated.” Polymarket’s public statement affirmed that it “acts…including through referrals to law enforcement and cooperation with investigations” and that “insider trading is not welcome.” White House spokesperson Davis Ingle reiterated that “all federal employees are subject to government ethics guidelines” and called unsubstantiated claims “baseless and irresponsible reporting.”
Criticism & Opposition: Legal Experts and Investigators’ Concerns
Rob Schwartz, a former Polymarket employee now with Morgan Lewis, described the pattern as “a new kind of insider trading.” Bubblemaps investigator Deebs warned that “there are, consequently, a lot of potential insiders,” emphasizing the difficulty of tracing information leaks among personnel involved in planning military operations.
Conflicting Reports & Gaps: Unverified Links and Ongoing Investigations
While the indictment of Van Dyke confirms illegal betting on a specific event, no public evidence directly ties any current administration official to the nine high-win accounts. The involvement of Donald Trump Jr. is noted only through investment ties, without allegation of participation in the bets. Law-enforcement investigations remain ongoing, and the extent of any coordinated insider network is undetermined.
