Judge Pacold rules for Kalshi while calling its contracts bets

A federal judge handed Kalshi a preliminary injunction in Illinois last Friday and spent the first three paragraphs of her opinion using the word "bet" six times.

Judge Martha Pacold did not hide the tension. The ruling blocked Illinois from enforcing its licensing rules against Kalshi's sports event contracts, but it did not clean up the legal picture. It added a new crease to it.

The case turned on a single clause in the Commodity Exchange Act — the phrase "the occurrence, nonoccurrence, or the extent of the occurrence of an event or contingency." Illinois argued the relevant event in a sports contract is the game itself, full stop. Kwame Raoul's office drew a line: a contract paying out on the Cubs winning is not a swap because a win is merely the result of the game; a contract paying out on the Cubs' season record is a swap because the season record is the event. Pacold looked at that distinction and wrote, plainly, that she found it unlikely. Statutes, she noted, do not usually draw lines so capriciously.

That reasoning put her in direct conflict with two circuit courts. The Ninth Circuit ruled against Kalshi in August. The Sixth Circuit ruled against Kalshi in late September. Pacold cited the Sixth Circuit's language on the definition of "event" approvingly, then rejected its conclusion. She also cited an Arizona ruling that read "the extent of the occurrence" as reaching how an event resolves, not merely whether it happens. Three circuits, three interpretations, one statutory clause.

I have watched legal splits like this one tighten around a case for months before the pressure finds a release valve. The release valve here is the Supreme Court. The newsroom has already tracked multiple parties petitioning for review. Pacold's ruling, which goes against two circuits while borrowing selectively from both, is the kind of opinion that makes a grant more likely, not less. It demonstrates that district courts are not waiting for appellate consensus — they are building their own.

What Pacold did not resolve matters as much as what she did. Illinois added transaction fees on prediction market sports trades in its fiscal 2027 budget. She declined to rule on whether those fees are federally preempted, ordering further briefing instead. That leaves the state with a tool Kalshi cannot yet neutralise, even where it wins on licensing. A state that cannot ban the product can still price it. That is not a theoretical concern — it is the next front, and it is already open.

The preliminary injunction is not a merits ruling. Pacold said as much. Kalshi cleared the likelihood-of-success bar for a preliminary hold, which is a lower standard than a final judgment. If the Supreme Court takes the underlying question and rules against Kalshi, this injunction dissolves.
