A 3-0 Ninth Circuit panel hands eight states of gaming risk back to Kalshi

For an operator, the 3-0 vote ^[2] matters less than how many places the phone rings next. Forty-four states have taken the position that these products are sports betting ^[5], the CFTC has sued nine of them to keep state gambling law off its licensees ^[7], and the subtraction leaves 35 states where no federal suit is pending and the exchange itself is the party that has to show up ^[13]. Inside the Ninth Circuit the arithmetic is tighter: federal judges in California, Arizona and six more states are bound by Friday's opinion ^[11], which is eight states of footprint sitting behind a precedent that calls the product gambling ^[12].

The equity move does not capture that. DraftKings rose 7% and Flutter, which owns FanDuel, rose more than 6% on the ruling ^[16], both having been marked down over the past year on the theory that prediction markets would take their volume ^[17]. Both have also been hurrying their own prediction-market exchanges into service ^[17], so the sentence they cheered, that the substance of a sports event contract is sports gambling regardless of what the exchange calls it ^[4], describes the thing they are building. The 7% move is a price, not a verdict on the licensing bill still to come.

What actually changed is who carries the burden. Under the Third Circuit's reading, a platform could point at its CFTC registration and stop there [c9a], which is roughly the argument Robinhood is still making, that the contracts are federally regulated and offered through its registered futures commission merchant ^[14]. Nevada's attorney general office, whose deputy communications director Alcinia Whiters said sports betting does not become something else because a company calls it an event contract ^[19], now has a panel opinion saying the same thing ^[3]. The CFTC's answer is textual and narrow: a swap is a swap regardless of subject matter, and the statute's only carve-outs are onions and movie box office receipts ^[8].

The routes out differ in cost. A cert grant that adopts the Third Circuit's view restores the shield and makes the next year a bridge expense; the Columbia professor Joshua Mitts calls this a classic circuit split, the kind that reaches the Supreme Court ^[10]. The CFTC's proposed rules, which would set up a review framework for sports-related event contracts ^[18], could reframe the fight from what the contract is to whether the agency cleared it, though a rule cannot rewrite a court's reading of the definition. And if no cert arrives, geography decides, with eight states in the gambling column and the Third Circuit's footprint in the other.

This is probably wrong, but the cheapest read is that federal-only compliance was the temporary version of the business, and that sports event contracts end up carrying state licensing and state tax in most of the 44 ^[5]. A 35-state gap between what states assert and what the CFTC has litigated ^[13] amounts to a queue of pending fights, not a shield against them. What would prove the thesis wrong is a Supreme Court reversal on the swap definition ^[3], or a final CFTC rule that state regulators actually treat as controlling ^[18]; short of either, every new state is a separate motion.

(CNBC, which reported the ruling, discloses a commercial relationship with Kalshi that includes customer acquisition and a minority investment ^[20]. Kalshi and Crypto.com did not immediately respond to its requests for comment ^[15].)
