• The DOJ charged Army Sgt. Van Dyke for using classified data to net over $400,000 on Polymarket.
• Stefan Muehlbauer notes that the case subjects decentralized platforms to the Commodity Exchange Act.
• A June 8, 2026, hearing will clarify legal standards for prediction market participants and operators.

An expert said recent indictments by the Department of Justice (DOJ) and the Commodity Futures Trading Commission (CFTC) signal an end to the “insider trading safe zone” in prediction markets. Stefan Muehlbauer, head of U.S. government affairs at Certik, argued the case establishes a precedent: Misappropriating nonpublic information — whether military or corporate — now carries the “same legal weight as traditional securities fraud.”

Muehlbauer’s comments came days after the U.S. granted bail to Gannon Ken Van Dyke, who made more than $400,000 in profit by betting on Polymarket that Venezuelan leader Nicolás Maduro would be ousted earlier this year. U.S. authorities assert Van Dyke opened the contract using privileged information in violation of the Commodity Exchange Act, which bars government employees from using nonpublic information in markets under CFTC jurisdiction.

As reported by Bitcoin.com News, Van Dyke’s lawyer has vowed to challenge the indictments. However, Muehlbauer, whose firm recently published a report on the growth of prediction markets, argues that subjecting decentralized platforms to the Commodity Exchange Act significantly boosts regulatory reach.

“By applying the Commodity Exchange Act and wire fraud statutes to these decentralized platforms, federal regulators have categorized event contracts as regulated swaps, effectively extending the fiduciary duty of confidentiality into the borderless crypto ecosystem,” Muehlbauer said.

The application of these laws suggests that prediction markets are being stripped of their “Wild West” reputation and subjected to stringent anti-manipulation rules. In other words, insider information in crypto now carries the same criminal liability as a Wall Street leak.

With the next court hearing in the case involving the Army sergeant set for June 8, operators and participants are watching closely to see how the outcome will impact the industry.

Meanwhile, Muehlbauer said the recent DOJ and Securities and Exchange Commission crackdown on market makers like Gotbit and ZM Quant proves that regulators view automated volume inflation as a criminal offense, regardless of a platform’s decentralized nature. To combat this, Muehlbauer urged market makers to follow standards for order book attribution and “proof of humanity,” ensuring that open interest reflects genuine human conviction rather than bot activity designed to simulate liquidity.

To mitigate cost-to-corrupt risks in the multi-billion-dollar prediction markets, the Certik executive called for a shift toward adversarial economic architectures where the cost of an attack is geometrically higher than the potential profit. For vulnerabilities like the oracle manipulation seen in the Mango Markets case, Muehlbauer said this entails replacing spot price oracles with multi-source, time-weighted averages that filter out wash trading and artificial spikes.

Addressing offline risks, such as the physical tampering of weather sensors, requires decentralized redundancy and cryptographic attestation. This ensures no single sensor or news desk can trigger a payout without consensus from independent, verified sources.
