The CFTC Just Charged Insider Trading on the Polymarket Platform It Doesn’t Regulate
The CFTC charged a Google engineer with insider trading on Polymarket’s offshore platform, asserting jurisdiction well beyond the exchange it licenses.
The Commodity Futures Trading Commission announced on May 27 that it has charged Michele Spagnuolo, a Google software engineer and Swiss resident, with insider trading on prediction market contracts tied to Google’s Year in Search list. According to the complaint, Spagnuolo used nonpublic information about the 2025 search rankings to buy “Yes” and “No” shares on at least 23 contracts, including markets on the most-searched person of the year, and generated roughly $1.2 million in profits. The US Attorney’s Office for the Southern District of New York unsealed a parallel criminal complaint the same day.
On its face, this is the CFTC showing the enforcement teeth it has been promising for months. Chairman Michael Selig has repeatedly said the agency will pursue insider trading regardless of the platform involved, and the agency has been under sustained pressure from Congress to prove it can police the prediction markets it has claimed jurisdiction over. This is a clean, well-documented case with a parallel criminal action attached.
There is a detail in the complaint, though, that complicates the clean narrative. The CFTC says Spagnuolo placed his trades on Polymarket.com. That is the offshore platform, not the US-regulated one.
There Are Two Polymarkets, and the CFTC Reached Into the Wrong One
Polymarket operates two distinct platforms. Polymarket.com is the original international exchange, built on the Polygon blockchain, which has historically not accepted US users and operates outside CFTC licensing. Polymarket US, accessed through a separate domain, is the CFTC-regulated entity that received its clearance to serve American customers. As we covered when Shayne Coplan defended insider trading as the platform’s core value, the distinction has become central to how the company operates, and it was the subject of a question House Oversight Chairman James Comer put to Coplan earlier this month: how does Polymarket keep US residents off the international platform?
The Spagnuolo complaint answers part of that question by accident. The CFTC is charging conduct that took place on Polymarket.com, a platform that it does not license. Spagnuolo is a Swiss resident, not a US one. The contracts were about a Google product. The only clear US hook is that Google is an American company and that the agency filed in the Southern District of New York.
There is no two ways about it that this is an aggressive assertion of jurisdiction. The CFTC is reaching beyond the regulated US exchange and into the offshore platform to charge a foreign national for trades in contracts based on a private company’s marketing list. The agency is entitled to make that reach under its anti-fraud and anti-manipulation authority, which is not strictly limited by where a platform is licensed. But it is a meaningful expansion of where the agency is willing to go, and it lands in exactly the gap between the two Polymarkets that regulators have been circling for months.
What This Jurisdictional Reach Says About the Future of the CFTC
The reason this is more than a technicality goes back to the structural tension Polymarket has been navigating, which we examined when Coplan made his case at Harvard. The company runs an international platform on the philosophy that insider trading is part of how prediction markets surface information, and a US platform that operates under the CFTC’s market-integrity rules. Coplan has continued to defend the former even as the latter became a regulated entity.
The Spagnuolo case suggests that the CFTC will not respect the boundary between the two. If the agency is willing to charge insider trading on Polymarket.com, then the philosophical position that the international platform operates under different rules becomes much harder to maintain. The “let insiders trade” argument was always going to collide with US enforcement once Polymarket held a US license. This case shows that the collision does not require the trades to have happened on the licensed platform at all.
It also signals something to every other prediction market operator. The CFTC is treating the entire prediction market space as within reach, not just the specific exchanges it has formally cleared. For an industry built partly on the idea that offshore and blockchain-based platforms exist outside traditional regulatory perimeters, that is a consequential message.
The Spagnuolo Case Itself Is Unusually Clean and Simple
The specifics of the Spagnuolo allegations also matter because they make this an easy case for the agency to win and a useful one for setting a precedent. Most of the insider trading concerns that have dogged prediction markets involve national security information, where the trades are difficult to trace to specific individuals and the underlying information is classified. The Army Special Forces soldier charged with trading on classified intelligence and the broader pattern of bets on US military operations fell into that category, and they are harder to prosecute cleanly.
The Spagnuolo case is quite the opposite from a legal standpoint. The information was a corporate marketing product, the Year in Search list. The trader was a named Google engineer who allegedly had direct access to the data. The trading pattern was, in the agency’s words, near-perfect across 23 separate contracts. The profits were specific and quantified at $1.2 million. There is even a colorful detail in the Polymarket handle that the complaint attributes to him, “AlphaRaccoon.”
This is the kind of case an enforcement division picks when it wants a clean win that establishes a principle. The principle here is that employment-based insider trading applies to prediction market contracts the same way it applies to securities. Spagnuolo allegedly owed Google a duty of confidentiality, breached it for personal gain, and did so in connection with event contracts. The CFTC is using a straightforward misappropriation theory in a novel venue.
What This Tells Us About the CFTC’s Posture
Taken together with the agency’s other recent activity, the Spagnuolo case fits a clear pattern. The CFTC is simultaneously defending prediction markets against state-level bans, as it did when it sued Minnesota over a law the state Senate passed alongside a sweepstakes ban, and aggressively policing insider trading on those same markets. The agency’s position is that prediction markets are legitimate, federally regulated financial products, and that their legitimacy depends on the agency being seen as enforcing integrity rules against bad actors.
The Spagnuolo charges are the enforcement half of that posture. The agency is telling Congress, which spent a recent hearing questioning whether the CFTC is capable of policing these markets, that it can and will bring cases. It is telling the prediction market industry that the regulated status comes with regulated obligations. And it is telling traders, including those on offshore platforms, that the agency’s reach extends beyond the boundaries of any single licensed exchange.
Whether the jurisdictional reach holds up is a question for the Southern District of New York. The agency clearly believes it can conduct a charge on Polymarket.com, and the parallel criminal action suggests federal prosecutors agree. If that theory survives, the practical distinction between the offshore Polymarket and the US one will matter a great deal less than Polymarket and Coplan have spent the past year arguing it should.
