A federal judge in Illinois handed prediction markets a significant win last Friday, ruling in favor of Kalshi, Coinbase and the Commodity Futures Trading Commission and blocking the state from imposing its sports gambling licensing regime on outcome-based sports event contracts.
The court found that Illinois cannot override federal authority by treating prediction markets as gambling operations subject to state oversight, since the CFTC is the ultimate regulator of swaps under federal law, according to the Daily Wire. The injunction remains in place in Illinois, but the legal question is far from settled nationwide.
A case in Wisconsin has already produced a ruling in the opposite direction, and that decision now sits before the Seventh Circuit Court of Appeals. Half a dozen similar disputes are stalled in courts across the country, setting up what could become the most consequential regulatory battle over financial innovation since the early days of cryptocurrency.
Who Actually Regulates Prediction Markets?
At the center of the fight is a deceptively simple question: when someone places a position on the next Oscar winner for Best Actor or the Super Bowl MVP, who sets the rules governing that contract?

Prediction markets — also called outcome markets — fall under the CFTC’s purview at the federal level, the same agency that oversees commodity futures and swaps markets. Several states, eager to capture tax revenue or shut the industry down entirely, have argued that their sports gambling statutes give them authority over these platforms. According to the Daily Wire’s analysis, that position misreads federal law.
CFTC Chair Mike Selig has been unambiguous on the matter. Speaking at a cryptocurrency conference in April, he said the CFTC holds “exclusive regulatory authority when it comes to commodity derivatives markets,” and characterized outcome markets as swaps that fall squarely within his agency’s jurisdiction.
Since then, the CFTC has filed nine lawsuits against states, aiming to reaffirm its exclusive authority over outcome markets and quash state-level attempts to regulate them — often with severe penalties attached. The most dramatic example came in March, when Arizona’s attorney general filed a criminal lawsuit against Kalshi, alleging the New York-based company was operating an “illegal gambling business in Arizona without a license.” A federal judge froze those criminal charges in April, with Selig warning that allowing states to use criminal statutes against federally regulated entities would set what he called a “dangerous precedent.”
Already Normalized, Already Everywhere
The stakes in this fight go well beyond who gets to collect licensing fees. Outcome markets have quietly become part of mainstream financial life.

Millions of consumers already use them as everyday tools for finance, investing and information-gathering. Nearly every major media outlet has partnered with prediction markets, which are used predominantly to track investor sentiment on political races and polling. The technology is embedded in mainstream finance applications, and financial news networks routinely cite these markets to gauge public opinion.
The concept actually originated in academia. The Iowa Electronic Markets predicted the winner of every major presidential race between 1988 and 2004, operating on the premise that participants with some “skin in the game” would prove more accurate than voters surveyed purely on sentiment. That track record helps explain why prediction markets are increasingly treated as genuine data points rather than curiosities.
The article notes that using whatever knowledge they have, users who trade on outcomes make transparent predictions about what they have reason to believe will happen — a signal that matches risk appetite with useful information. This distinguishes them meaningfully from sports gambling websites, despite the two being frequently lumped together.
States See a Payday
The revenue motive is not subtle. Illinois’s desire to tax prediction platforms to the tune of $880 million lays bare what’s really driving the state-level push, according to the Daily Wire.

Where the CFTC has shown flexibility in accommodating these novel questions, states have been happy to shoehorn outcome markets into their existing sports gambling frameworks — frameworks that promise excessive taxes, restrictive user rules and 50 different regulatory regimes for Americans trading on outcomes.
That said, the regulatory picture is genuinely unsettled. Questions about insider trading, age limits and how to address addiction remain open territory for courts and regulators alike. Both sides acknowledge that outcome markets represent a new kind of financial instrument that doesn’t fit neatly into existing categories.
What distinguishes the two approaches, the Daily Wire argues, is that the CFTC brings more relevant experience and authority to these questions, while states are largely applying gambling rules designed for a different industry to a federally regulated derivatives market.
Users and observers of these markets understand their utility, as do the CFTC and the Trump administration, per the article. States, meanwhile, see prediction markets as the next activity to tax, regulate and control — and they are counting on a payday.
Viewed through that lens, the Daily Wire concludes the CFTC has the better argument. But with a split between circuits already emerging and more cases waiting in the wings, the question of who ultimately polices prediction markets seems destined for the Supreme Court.
