Following the landmark indictment in United States v. Van Dyke, federal charges for insider trading in prediction markets now mirror traditional white-collar prosecutions, utilizing a combination of wire fraud, commodities fraud, and the "misappropriation theory" to penalize the use of nonpublic information.
Federal prosecutors and the Commodity Futures Trading Commission (CFTC) have signaled that “fraud is fraud,” regardless of whether the trade involves a stock or an event contract, effectively ending the era of legal ambiguity for traders on platforms like Polymarket and Kalshi.
Insider Trading on Prediction Markets
The Government has officially classified insider trading on prediction markets as a federal crime, treating these platforms as regulated commodity markets rather than mere betting sites. In the recent landmark case United States v. Van Dyke, federal prosecutors and the CFTC charged a U.S. Army soldier with commodities fraud and wire fraud for allegedly using classified information about a military operation to profit from event contracts on Polymarket.
This prosecution establishes that the "misappropriation theory"—long used in stock market cases—applies to prediction markets, signaling that anyone who trades on nonpublic information in breach of a duty faces the same severe penalties as traditional Wall Street insiders.
The Van Dyke Case: The First Criminal Prosecution and What It Tells Us
The Five Felony Counts
- Unlawful Use of Confidential Government Information for Personal Gain
This count utilizes a specific provision of the Commodity Exchange Act (CEA) often called the "Eddie Murphy Rule." It states that as a federal employee, Van Dyke used nonpublic government information (details of a military operation) to trade in "swaps" or commodity contracts for personal gain. This is significant because it explicitly treats prediction market contracts as regulated commodities.
- Theft of Nonpublic Government Information
While similar to the first count, this focuses on the misappropriation of the information itself. The government argues that the classified details belonged to the United States and that Van Dyke “stole” or converted that property for his own use. This establishes that government secrets have tangible value that can be the subject of a theft charge.
- Commodities Fraud
This is the core “insider trading” charge under the CEA. It alleges that Van Dyke engaged in a scheme to defraud other market participants by trading on material nonpublic information (MNPI) while under a duty of trust. By bringing this charge, the government is treating the “YES” shares on Polymarket identically to how they would treat oil futures or gold contracts.
The government charged Van Dyke with using electronic communications (i.e. the internet, crypto transfers, and prediction market interfaces) to execute a scheme to obtain money or property through deception. This count is powerful because it doesn't require the government to prove the trades were “commodities’’ only that he used the “wires” to carry out a fraud.
- Engaging in a Monetary Transaction in Property Derived from Specified Unlawful Activity
Commonly referred to as Money Laundering, this count specifically targets what happened after the trades. Because Van Dyke allegedly transferred more than $10,000 of “criminally derived property” (the $400,000 in profits) from his Polymarket account into a foreign crypto vault and then a brokerage account, he is charged with moving “dirty money” through the financial system.
Misappropriation Theory and the “Eddie Murphy Rule”
The Misappropriation Theory
This is the modern backbone of insider trading law. Under this theory, a person commits a crime when they steal or “misappropriate” confidential information to trade on it, thereby violating a duty of trust owed to the source of the information (like an employer or the government).
- In Practice: You don't have to be a “company insider” (like a CEO) to be charged. If you are a government employee, lawyer, or consultant and you use secret info you learned on the job to trade on a prediction market, you have effectively “stolen” that info for personal gain.
- The Van Dyke Application: Prosecutors argue Van Dyke owed a duty to the U.S. Army to keep military plans secret; by trading on those plans, he misappropriated that “property” for his own profit.
The “Eddie Murphy Rule”
Formally known as Section 4c(a) of the Commodity Exchange Act (CEA), this rule was inspired by the plot of the 1983 film Trading Places. It explicitly prohibits federal employees from using nonpublic information to trade in the commodities markets.
- The Origin: In the movie, characters use a stolen, secret government crop report to corner the market on orange juice futures. Before the 2010 Dodd-Frank Act, this wasn't clearly illegal; the “Eddie Murphy Rule” was created to close that loophole.
- Why it matters now: By invoking this rule, the government is legally defining prediction market “event contracts” as commodities. This allows the CFTC to go after government officials who use their “inside track” on policy, elections, or military actions to win big on platforms like Kalshi or Polymarket.
Who is Actually at Risk
The indictment of Gannon Van Dyke has shattered the "myth" that prediction markets are a legal grey zone. By treating event contracts as regulated commodities, the DOJ and CFTC have effectively expanded the pool of potential defendants far beyond traditional Wall Street.
- Government Employees and Military Personnel
Federal employees are at the highest risk due to the “Eddie Murphy Rule.” If you have access to classified briefings, upcoming policy shifts, or sensitive geopolitical data, using that knowledge to trade on platforms like Polymarket or Kalshi is now a direct path to a felony indictment.
- Corporate Insiders and Contractors
The “misappropriation theory” means that anyone with a duty of confidentiality to their employer is in the crosshairs. This includes:
- Tech employees who know about a product launch delay.
- Lawyers or consultants privy to unannounced M&A activity or regulatory rulings.
- Supply chain managers who see "boots on the ground" data before it hits the news.
The Standard: If the information you used to make a trade was not available to the public and you had a professional duty to keep it secret, you are at risk. Federal prosecutors no longer care if you bought “shares” or “stocks” they only care that you cheated the market.
Civil and Criminal Exposure
The legal consequences for prediction market insider trading are now bifurcated into two high-stakes tracks: criminal prosecution by the Department of Justice (DOJ) and civil enforcement by the Commodity Futures Trading Commission (CFTC).
Criminal Penalties (DOJ)
The DOJ targets the individual's liberty and seeks to punish the “intent to defraud.” In United States v. Van Dyke, the charges carry staggering maximum sentences:
- Wire Fraud: Up to 20 years in federal prison.
- Commodities Fraud: Up to 10 years per count.
- Money Laundering: Up to 10 years (for transactions over $10,000 using criminal proceeds).
- Fines: Criminal fines can reach $250,000 per count for individuals, or twice the gross gain/loss from the offense—potentially totaling millions.
Civil Penalties (CFTC)
While the CFTC cannot send you to prison, they can effectively end your financial life and career in the markets. Civil enforcement typically focuses on “restoring” the market and deterring others.
- Civil Monetary Penalties (CMPs): The CFTC has the authority to impose significant civil CMPs, which are adjusted annually for inflation.
- Disgorgement: You are required to pay back 100% of your profits plus interest.
- Trading Bans: Permanent injunctions that bar you from ever trading on regulated exchanges or prediction markets again.
- Restitution: In cases where other traders were harmed, you may be ordered to pay “victim restitution” to cover their losses.
The “Double Jeopardy” Reality
It is important to note that these are not “either/ or” scenarios. As seen in the Van Dyke case, the government will pursue parallel proceedings.
How These Cases Are Actually Defended
- Lack of “Materiality”
For information to be illegal to trade on, it must be material, meaning there is a substantial likelihood that a reasonable investor or trader would consider it important.
The Defense: A defense lawyer may argue that the “inside info” was actually common knowledge, rumored heavily on social media (e.g. X, Instagram, Facebook, etc.), or already “priced in” by sharp market participants. If the public was already betting 90% on a specific outcome, the defendant’s private knowledge might be deemed immaterial.
- The “Mosaic Theory”
This is a classic Wall Street defense. It argues that the trader didn't rely on a single “stolen” secret, but rather pieced together a conclusion from dozens of public, legal sources.
The Defense: A defendant might show they used public flight trackers, satellite imagery, and news snippets to build a "mosaic" of information. Even if they had access to private data, the defense argues the trade was the result of their own independent research and superior analysis, not a breach of duty.
- Absence of a “Duty of Trust”
The Misappropriation Theory only works if the trader owed a specific duty to keep the information secret.
The Defense: If an employee's contract or the company’s handbook is vague about "event contracts" or "prediction markets," the defense may argue there was no clear duty of confidentiality regarding that specific information. In Van Dyke, the government cited a signed NDA; without a clear document or policy, proving a “fiduciary duty” becomes much harder for the prosecution.
What to Do if the CFTC, SDNY, or a Prediction Market Platform Contacts You
The United States v. Van Dyke indictment signals that the Government is no longer treating prediction markets as a playground for “informed” betting. If you receive a subpoena from the CFTC, a knock from the SDNY, or a freeze notice from a platform like Kalshi or Polymarket, your immediate actions will determine your legal exposure.
- Maintain Absolute Silence
The most common mistake is attempting to explain away a trade to federal agents or platform compliance officers. Anything you say—including "I just saw it on Twitter"—can be used to build a "false statements" charge if investigators find contradictory evidence in your private messages or on-chain data. Politely decline to answer questions until you have consulted with counsel.
- Preserve All Records
The DOJ frequently adds Obstruction of Justice charges to insider trading cases when they discover deleted Signal messages or wiped hard drives. In the Van Dyke case, investigators relied heavily on recovering communications that the defendant thought were private. Do not delete accounts, clear browser histories, or move crypto assets once you are aware of an investigation; these actions are often viewed as “consciousness of guilt.”
- Do Not "Test" the Platform's Security
If a platform freezes your account, do not attempt to bypass the freeze using a VPN, a new "burner" account, or a friend’s wallet. Prediction market surveillance is now highly sophisticated, and attempting to circumvent a freeze provides the government with evidence of “sophisticated means” and intent, which can lead to a significant increase in your potential prison sentence under the Federal Sentencing Guidelines.
- Engage Experienced Counsel Immediately
Prediction market cases sit at the intersection of traditional commodities law and emerging crypto regulation. When the weight of the federal government is focused on your trades, your freedom depends on a team of experts who can navigate the complex intersection of digital assets and white-collar defense.
