New Insider Trading Charges Target US Serviceman and KPMG Employee Over Polymarket Bets
TL;DR — US prosecutors charged a serviceman and KPMG employee with insider trading on Polymarket using military and earnings data. This expands cases against Van Dyke, Spagnuolo, and two Israeli officers. A report flagged 152 suspicious accounts; Polymarket referred nearly 100 to authorities amid CFTC jurisdictional disputes.
SCCG Take — These cases demonstrate effective individual enforcement but expose limits in holding offshore platforms accountable, pressing regulators to clarify CEA scope for prediction markets.
US authorities have leveled fresh criminal charges against a serviceman and a KPMG employee accused of trading on nonpublic information through prediction markets. The serviceman placed successful bets on Polymarket tied to military actions in Iran and Venezuela. The KPMG employee allegedly used access to private financial data to wager on whether a public company would exceed consensus earnings estimates.
These actions add to a series of prosecutions that include Gannon Ken Van Dyke, a US soldier, and Michele Spagnuolo, a Google engineer. Both face charges for using insider information to trade on Polymarket. Two Israeli military officers have also been arrested for similar activity related to Middle East conflict markets. One of the Israeli Air Force officers stated that wagering on prediction markets is rife among servicemen.
Mounting Evidence of Suspicious Activity on Military Markets
The Anti-Corruption Data Collective identified 152 accounts that generated substantial profits on military-related markets on Polymarket. The platform has referred nearly 100 accounts to authorities after surveillance flagged suspicious trading patterns. The Wall Street Journal reported that the CFTC and prosecutors in New York and Washington are pursuing the matters. Polymarket is banned in over 40 countries, yet it maintains war-related markets on its international platform.
Defense Challenges to CFTC Jurisdiction
Defense lawyers for Van Dyke and Spagnuolo argue that the CFTC has overstepped its authority. They contend the traded contracts do not qualify as swaps under the Commodity Exchange Act and that the agency lacks jurisdiction over a non-US citizen using a non-US platform. Spagnuolo allegedly profited $1.2 million from the trades. CFTC Chair Michael Selig said the agency has the ability to pursue cases involving offshore platforms in extreme circumstances. While individuals face prosecution, the CFTC has taken no apparent steps to restrict Polymarket from offering these markets. This leaves open the boundary between individual accountability and platform oversight in cross-border prediction trading.
