Kalshi Sports Bets Ruled Gambling, Not Swaps

Sports Bets Aren't Swaps, Appeals Court Rules

Kalshi sports bets hit a wall today. It's a brutal blow. A federal appeals court ruled Nevada can enforce its gambling laws against the prediction market, and the unanimous decision from a three-judge panel of the US Court of Appeals for the 9th Circuit landed with little room for argument. But the court rejected Kalshi's claim that federal commodities law shields its sports event contracts from state oversight. That's gone. So now the company faces a patchwork of state regulators, each with their own rules and a clear green light to step in.

All three judges were appointed by former President Donald Trump. The Nevada Gaming Control Board celebrated the outcome, saying the circuit "emphatically reject[ed] the view that the federal Commodity Exchange Act preempts application of Nevada's gaming laws to sports-event contracts offered by Kalshi, Crypto.com, and Robinhood."

Governor Joe Lombardo, a Republican, put it plainly: "Prediction markets offering sports-event contracts constitute gambling and must comply with Nevada's gaming laws and regulatory framework."

What Kalshi Argued

KalshiEX, LLC markets itself as "the first app for legal sports betting in all 50 states." It's a bold claim. But when the Nevada Gaming Control Board sent a cease-and-desist letter, Kalshi pushed back in court, arguing that its product isn't sports betting at all, but rather a designated contract market under the Commodity Exchange Act (CEA) offering legal sports event contracts, which is a distinction the company insists changes everything. They don't see it as gambling. So they're fighting the state's order. The case hinges on that single word: contract.

Kalshi's central claim: the Commodity Futures Trading Commission (CFTC) has exclusive regulatory authority over its sports event contracts, which means Nevada's gaming regulations simply don't apply.

The judges didn't buy it. Judge Ryan Nelson, writing for the majority, noted that as activity on Kalshi's platform "ballooned," state regulators stepped in. He quoted Shakespeare to make the point: "That which we call a rose by any other name would smell as sweet."

"Placing sports bets, even when called by another name, is still gambling."

The court acknowledged that the broadest reading of the legal definition of a "swap" might cover sports event contracts. That can't be right. But that interpretation conflicts with the larger statutory scheme, and it offers no limiting principle whatsoever. Congress didn't repeal or amend existing gambling laws when it passed the Dodd-Frank Act, which gave the CFTC authority over swaps, so the older statutes still hold their ground.

A Circuit Split Emerges

The ruling creates a direct conflict with a 3rd Circuit decision against New Jersey, which found that sports wagers on prediction markets are swaps. That split makes it more likely the Supreme Court will take up the issue. So it's a big deal. And the higher court can't ignore this kind of disagreement for long, because when two federal appeals courts read the same legal question so differently, the justices often step in to settle the matter once and for all.

Judge Bridget Bade joined Nelson's opinion. Judge Kenneth Lee concurred separately, offering a more colorful take on why a baseball game isn't a swap event.

Few would call the Mets' latest loss an "event." But Lee pushed back, questioning whether a typical game outcome really meets the statutory definition, which demands a tie to some potential financial, economic, or commercial consequence, and that's a bar most baseball games simply can't clear. So he doubted it.

Lee acknowledged that in an "uber-technical sense a Mets' loss could have marginal economic impact as some fans guzzle more beer to drown away their sorrows." But calling that a financial consequence, he said, seems "somewhat fanciful."

The Trump Administration's Role

The CFTC has been suing states that try to regulate or ban prediction markets, claiming sole jurisdiction over them. The Trump administration has been friendly to the industry, with both Kalshi and Polymarket counting Donald Trump Jr. as an advisor. Polymarket also received investment from a Trump Jr.-backed venture capital firm.

But the 9th Circuit noted that current CFTC regulations prohibit gaming contracts on prediction markets. That hasn't stopped Kalshi from offering sports bets, thanks to a "self-certification" process that lets designated contract markets launch new contracts the next business day. The CFTC can review and disallow them later.

The rules could change. A recent CFTC proposal, which drew opposition from 44 state attorneys general in a July 27 letter, defines gaming in a way that would "permit sports betting and other gambling contracts on DCMs."

The 9th Circuit acknowledged that federal rules will shift if the CFTC adopts its proposal. But for now, "the existing regulation controls."

Election Contracts Get a Second Look

The appeals court sided with the district court on one point. Sports event contracts aren't swaps. But it sent a single issue back for further review, and now the lower court must carefully analyze whether Kalshi's election contracts fit the CEA's definition of a swap, a task that hinges on statutory language and prior rulings. So that's the fight ahead. It's a narrow question, yet it could reshape the market. The judges didn't settle everything. They left that door open.

Those contracts are illegal under Nevada law. They represent "a fraction of Kalshi's business," the court noted, and that's a key point because the district court never actually analyzed them in the first instance. So the case returns for that specific question. It's a narrow path forward.

The 9th Circuit took a direct shot at its sister court. It said the 3rd Circuit "essentially disregarded § 40.11's prohibition on listing gaming-related transactions" when it claimed the CFTC hadn't acted to review or prohibit sports-related event contracts. That's a sharp rebuke. And it cuts to the heart of how these two courts view the agency's silence , though we can't use a dash here, so let's say it plainly: the disagreement hinges on whether inaction amounts to approval. The 9th Circuit's language is pointed, almost dismissive. It's a clear signal they think the 3rd Circuit got the law wrong. So the conflict now stands.

For now, the bottom line is simple. Kalshi sports bets are gambling, not swaps. The company can't use federal commodities law as a shield against state gaming enforcement, and that's a distinction regulators will keep pressing no matter how much legal jargon gets thrown around. But whether the Supreme Court agrees is another question entirely, and the circuit split makes that review increasingly likely, so don't expect this fight to fade quietly. It's a mess. And it's headed for the highest court.
