After several appeals court losses, Kalshi has secured a win against state regulation in Illinois.

A federal district court judge ruled that Illinois cannot impose its state gambling legislation on prediction markets, namely Kalshi and Coinbase. They are, Judge Martha Pacold, beholden to federal regulators – namely, the Commodity Futures Trading Commission (CFTC).

Despite the loss for Illinois’ gambling industry, judgment was withheld on whether prediction markets should pay tax in the state. There is still the possibility that Kalshi and others may have to pay tax on profits in the future.

Prediction Markets ‘Likely Swaps’, Judge Says

Kalshi called the Illinois ruling “beautiful” as Pacold declared prediction markets to be “likely swaps” as spelled out in the Commodity Exchange Act (CEA) – the law that currently oversees exchanges. “Illinois law is likely pre-empted,” she added.

Illinois had argued that Kalshi’s event contracts – specifically on sports – were illegal. However, this argument was thrown out, and the CFTC did not ask the exchange to remove its markets.

States vs. Federal: The Predictions Challenge

The federal court judgment throws more doubt on whether states can regulate prediction markets themselves.

While prediction markets were set up primarily for trades on financial outcomes, they have diversified into entertainment, politics, and sport.

It’s the last of those new additions that has so riled state regulators.

Sports event contracts, the states say, are no different from sports bets and must be regulated as such.

However, the Illinois federal district court determined that sports contracts are swaps.

They therefore should adhere to a “broad regulatory regime designed to bring futures markets under a uniform set of regulations.”

In the eyes of Illinois lawmakers, that essentially makes sports betting legal across the U.S. through the back door.

Kalshi Win First Since July

Kalshi has been on the wrong end of legal defeats over whether they answer to the CFTC or state gaming commissions.

It did win in New Jersey in April when the Third Circuit U.S. Court of Appeals ruled in its favor.

However, NJ retaliated by petitioning the Supreme Court on who should oversee the exchanges.

The North American Gaming Regulators Association (NAGRA) and International Association of Gaming Regulators (IAGR) have come out in support of NJ vs. Kalshi.

Elsewhere, it’s been a story of crackdowns and geofencing for Kalshi.

The Sixth U.S. Court of Appeals in Cincinnati last month ruled that Ohio and Tennessee can regulate Kalshi under sportsbook law. Event contracts, it argued, lacked a “potential financial, economic, or commercial consequence,” making them bets – not swaps.

Nevada also secured a win in the Ninth Court, winning the argument that its gaming board should regulate.

Prediction Markets Face ‘Irreparable Harm’, Court Argues

The federal court in Illinois also cited the financial implications of a change in regulation for Kalshi and Coinbase.

They faced, the court argued, “irreparable harm” if forced to make the ultimate choice between shutting up shop or paying heavy fines by the state.

Plus, the court said that, “neither Illinois nor the public has much interest in enforcing laws that are likely preempted.”

Supreme Court Ruling Now Seems Likely

New Jersey has already asked the U.S. Supreme Court to review its loss in the courts. Some reports suggest the Supreme Court could make a definite ruling on who regulates predictions sometime next year.

The CFTC is backing the prediction market exchanges, although there are moves to bring in bipartisan legislation on sports contracts.

Two U.S. senators introduced the ‘Prediction Markets Are Gambling Act’ in March in an attempt to outlaw anything “resembling a sports” or casino game.

The CFTC is already making moves to clarify what exchanges should and shouldn’t offer. It wants prediction market platforms not to use gambling odds on their sites. Plus, last month it issued rules to stop exchanges offering casino-style games. However, details on what those “casino-style games” included were light.
