CFTC Director Issues Warning on Prediction Market Trading
David Miller, the enforcement director at the Commodity Futures Trading Commission, made his position clear this week. Speaking at a New York University panel, he said the agency is watching prediction markets closely for insider trading activity. “We are aware of the speculation about insider trading,” Miller stated. “We are watching.”
This isn’t just talk, I think. Miller, who took his position in March after serving as a federal prosecutor, said the CFTC will use its prosecutorial discretion. But he emphasized they won’t waste resources on trivial cases. “We will only be prosecuting cases against those who tip or trade with misappropriated information,” he told Bloomberg.
Event Contracts Are Swaps, Not Gaming
Here’s where it gets interesting. Miller clarified the CFTC’s legal position on prediction markets. “Our position is that event contracts are not gaming,” he said. “The event contracts at issue are swaps. Insider trading law applies.”
That distinction matters quite a bit. If these were considered gaming, different rules might apply. But as swaps, they fall under the CFTC’s regulatory umbrella. Miller said the Commission will focus on core enforcement areas including market abuse and violations of anti-money laundering laws.
Recent Trades Sparked Concerns
Prediction market insider trading became a hot topic recently. There were some well-timed trades ahead of major announcements by former President Donald Trump. Then there was that anonymous trader who bet on the capture of Venezuelan leader Nicolás Maduro and made over $400,000.
More recently, users placed suspicious trades related to Iran’s invasion and the death of Ayatollah Khamenei. These trades raised national security concerns, which perhaps explains why lawmakers are paying attention now.
Platforms and Lawmakers Respond
In response to all this attention, the two leading prediction market platforms, Kalshi and Polymarket, introduced new insider trading rules. They’re trying to self-regulate before regulators step in more forcefully.
Lawmakers aren’t waiting around either. In late March, bipartisan legislation was introduced—the Public Integrity in Financial Prediction Markets Act of 2026. That same week, another bill called the Preventing Real-time Exploitation and Deceptive Insider Congressional Trading Act (PREDICT Act) was proposed.
Democratic lawmakers have been pressing the CFTC too. They want the agency to warn federal employees not to use inside knowledge for prediction market trading. The monthly volume in these markets recently exceeded $20 billion, according to TRM Labs, so there’s real money at stake here.
It feels like we’re at a turning point for prediction markets. They’ve grown quickly, but now regulators and lawmakers are catching up. Miller’s comments suggest the CFTC is taking this seriously, but they’ll be selective about which cases to pursue. The platforms are trying to get ahead of regulation, but legislation is already moving through Congress.
What happens next? Probably more scrutiny, maybe some test cases from the CFTC. The industry’s credibility is on the line, and everyone seems to recognize that. Whether self-regulation will be enough, or whether we’ll see more formal rules—that’s the question now.
