Regulatory Showdown: Who Rules Prediction Markets?

The Regulatory Jump Ball Over Your Next Trade

For three decades, the CFTC has called the shots on event contracts. A 1992 ruling on the Iowa Electronic Markets set the precedent, and the commodities watchdog has been the lone sheriff in town ever since. But that era is ending. The explosive growth of prediction markets has triggered a quiet, high-stakes turf war in Washington. The question isn't just academic—it will define the rules, protections, and very future of this novel asset class.

The core issue? Jurisdiction. "The CFTC has come out saying that they have jurisdiction over the event contracts, but there's also some that seem like they're more in the SEC's realm," notes Joe Zales, a partner at King and Spalding. This isn't a hypothetical debate. Last month, the SEC and CFTC issued a joint request for public comment, explicitly putting definitions for swaps and "novel or emerging products" under the microscope. Translation: They're drawing the battle lines now.

Why the SEC Wants a Piece of the Action

For traders, the SEC’s potential entrance boils down to one law: Dodd-Frank. While the CFTC typically regulates swaps, the SEC gets jurisdiction over securities-based swaps—contracts tied to a single security. This is where it gets messy for your trades.

Think about a contract asking, "Will NVDA stock end the month up more than 5%?" That’s a direct link to a public security. Legal experts point to this as a clear-cut case for the SEC. But the law's language is a minefield. A securities-based swap is also defined as a contract that "directly affects" a company's financials. What does "directly affects" mean? Nobody is sure.

"That ambiguity is exactly what's being tested now in real time," says Sarah Razaq Sallis of Husch Blackwell. Consider a contract on when AAPL will release its next iPhone. It’s not directly tied to the share price, but the launch of a flagship product sure moves the stock. Which agency owns that trade? The answer will determine the SEC's role—and the regulatory burden on platforms.

Some firms aren't waiting. CBOE has already filed to operate under the SEC's umbrella for binary options on corporate KPIs. The race to pick a regulator is on.

A History of Rivalry, a Moment for Truce?

If you think this tension is new, think again. "These agencies have been at each other's throat jurisdictionally," says Jerome Tomas, a former SEC employee now at Baker McKenzie. We saw it play out publicly with crypto. The CFTC, younger and smaller, often clashes with the larger, more established SEC. Their rulebooks and philosophies are fundamentally different.

But right now, there's a unique window for detente. Both commissions are understaffed and dominated by Republicans. The SEC has only three seated commissioners (all GOP), and the CFTC has just one: Chairman Michael Selig. "I think this is the easiest time for these two agencies to get on the same page," observes Aaron Klein of the Brookings Institution.

In March, they signed a memorandum of understanding to coordinate definitions, oversight, and data sharing. The market is watching to see if this cooperation is real or just another temporary ceasefire in a decades-long cold war.

What This Means for Your Trading Account

For platforms like Kalshi and Polymarket, clarity is everything. A Polymarket spokesperson voiced a common industry fear: "duplicative or conflicting compliance requirements that could harm innovation." Navigating one regulator is hard enough; managing two is a compliance nightmare that could stifle the space.

But for Wall Street, SEC involvement could be the golden ticket. Institutional money craves certainty. "To the extent that the SEC actually chimes in... it expedites [institutional adoption] pretty substantially," says Troy Dixon of Tradeweb Markets, which partners with Kalshi. The big banks and funds are waiting on the sidelines for clear rules of the road.

Expect changes at the retail level, too. Joe Zales predicts the SEC's involvement could mean "tighter protections for traders," including a more cumbersome account opening process. Think more forms, more disclosures—the classic SEC playbook for investor protection.

The Path Forward: Clarity vs. Speed

So, what's the endgame? Most experts believe the CFTC will retain its primary role, with the SEC playing a supporting part for contracts clearly tied to securities. This "harmonization," if done right, could be a net positive, creating a more robust framework.

But there's a catch. Peter Chan, a former SEC attorney, warns against a rush to regulate. "I think what is required is not necessarily real time rule making, but I think it requires real-time learning," he argues. The agencies need to understand these markets before boxing them in with outdated definitions.
