CFTC Chairman Michael S. Selig isn’t backing down. The head of the US commodities regulator has made clear the agency will defend its exclusive authority over prediction markets if states try to challenge it in court.

The fight for jurisdiction

Selig first laid out his position in a February 17, 2026 Wall Street Journal op-ed, where he underscored the CFTC’s long history of overseeing event contracts, the technical term for prediction markets. He followed up with even more direct comments in April 2026, explicitly affirming the agency’s exclusive regulatory role.

The pushback is coming from several directions. States including Nevada, New York, Illinois, and Arizona have been asserting their own regulatory claims over prediction markets. Nearly 50 ongoing cases involving CFTC-registered platforms illustrate just how heated this jurisdictional battle has become.

In his WSJ op-ed, Selig referenced the filing of an amicus brief for Crypto.com, signaling the agency’s willingness to intervene in legal proceedings to protect its turf.

A regulator with a different disposition

Selig’s approach marks a notable departure from previous CFTC leadership. Since his appointment on December 22, 2025, the former corporate lawyer, who previously represented crypto firms and prediction market platforms, has steered the agency toward a more innovation-friendly posture.

The CFTC retracted earlier proposals that would have imposed tighter restrictions on event contracts and initiated new rulemaking aimed at establishing clearer standards.

The most concrete result so far came in late May 2026, when the CFTC approved Kalshi to offer Bitcoin perpetual contracts. Bitcoin perpetual futures, essentially contracts that let traders bet on Bitcoin’s price without an expiration date, have been enormously popular on offshore exchanges for years.

Why this matters for crypto investors

Polymarket, built on the Polygon blockchain, became a cultural phenomenon during the 2024 US presidential election. Kalshi has been aggressively expanding its product lineup. Together, these platforms represent a new asset class that blends elements of derivatives trading, sports betting, and information markets.

The $60 billion combined valuation of Kalshi and Polymarket already signals serious market confidence. But that number is contingent on regulatory clarity.

If regulated US platforms can offer the same products that previously only existed on offshore exchanges like Binance and Bybit, it could pull significant trading volume onshore.

Those nearly 50 active cases aren’t going away overnight. State regulators have their own incentives, including tax revenue and consumer protection mandates, to maintain oversight. Traders and investors should watch the Nevada and New York cases most closely, as those states have the most developed gaming and financial regulatory frameworks, respectively.
