Kalshi is fighting for its life right now. The prediction market absolutely blew up this year — both in the volume of trading it’s doing (mostly in sports contracts) and its own valuation (now $11 billion).
Of course, when you’re having this type of success, people start coming after you. Top sports betting apps. Regulators. Everyday people. Native-American tribes. That’s where we are right now in Kalshi’s story.
So far, it’s been a mixed bag for Kalshi. Wins against some state courts, losses against others. But the platform just got, arguably, its biggest ‘W in California. Here’s a state where tribes run California sports betting, and they see Kalshi as a threat to that monopoly. Keep reading, and we’ll update you on the two sides back-and-forth in the Golden State.
California Tribes Come Up Empty Against Kalshi
The United States District Court for the Northern District of California denied a motion from three California tribes — Blue Lake Rancheria, Chicken Ranch Rancheria, and Picayune Rancheria of the Chukchansi Indians — that wanted Kalshi shut out of tribal lands. The tribes wanted money, damages, and a ruling that Kalshi and Robinhood (the stock trading app that now offers prediction markets from Kalshi) violated both the Indian Gaming Regulatory Act (IGRA) and the Lanham Act.
The ask was simple: block Kalshi from offering its yes/no sports markets on tribal land and stop it from advertising that its contracts are “legal in all 50 states.” The judge disagreed on both fronts. The tribes couldn’t show they were likely to win the case so the court refused to block anything.
The tribes argued Kalshi’s sports markets were basically Class III casino gaming — the same category as Vegas-style slots, blackjack, and sports betting — and that only tribal casinos can offer those games under compacts with the state. But the court didn’t buy it.
Under IGRA, a court only has jurisdiction if someone is running Class III gaming on tribal land in violation of a compact. That’s not what’s happening here. The compacts for these tribes only outline what the tribes can operate, not what outside companies can do on the open internet. The agreements are silent on third-party platforms.
Put bluntly: IGRA covers tribal gaming, not every website that someone on tribal land might access. So IGRA didn’t give the court a legal basis to shut Kalshi down. Not yet, at least.
Who Governs Kalshi In California?
The court also leaned on another federal law — the Unlawful Internet Gambling Enforcement Act (UIGEA). UIGEA bans processing payments for illegal online gambling, but it has a massive caveat: anything operated through a registered entity under the Commodity Exchange Act (CEA) is not considered a “bet or wager.”
Kalshi is a registered entity. The tribes didn’t challenge that. And because Kalshi’s contracts run on its CEA-regulated exchange, the court said UIGEA, not IGRA, governs the activity. Check mate, folks!
That’s a lot of acronyms, we know, but here’s the key line from the judge you need to be aware of: because Kalshi is registered under the CEA, its contracts “are not bets or wagers under the UIGEA,” even if someone sits on tribal land and trades them. That means they can’t be treated as illegal sports betting.
California Judge Ignores The “Swap” Debate
This ruling landed just days after a Nevada judge ruled that Crypto.com’s sports contracts aren’t “swaps” under the CEA — a decision that worked against prediction markets. The tribes tried to use that ruling as backup. The judge in California didn’t bite, though.
Because the “swap vs. event contract” argument wasn’t raised in the tribes’ original filings, the court refused to consider it here. However, the judge did leave the door open for the tribes to bring the issue back later when Kalshi’s motion to dismiss is heard in March 2026, just four months from now.
Even so, the order hinted at something bigger: decisions about whether event contracts violate the CEA belong to the CFTC, not individual courts. One prior Nevada ruling (Kalshi v. Hendrix) was cited to reinforce that point.
The judge spelled it out: only the CFTC “may determine” whether an event contract should be reviewed or blocked. Courts don’t get to make that call. And if states or tribes don’t like that? Their recourse is with Congress, not the judiciary.
Lanham Act Claim Also Falls Flat
The tribes also accused Kalshi of false advertising for saying its product is legal nationwide. Par for the course, the California court shut that down quickly too.
First, Kalshi’s statements are framed as an opinion — and given recent court rulings siding with Kalshi, that opinion isn’t “literally false.” Second, the tribes couldn’t show competitive injury. To win a Lanham Act case, you have to prove the other company’s advertising actually hurts your business. The tribes couldn’t make that case.
So the Lanham Act claim work. The IGRA claim didn’t either. All this means is Kalshi is currently clear to operate in California. But for how long?
This is the billion-dollar question, plaguing not just Kalshi but the entire legalized betting industry. Some states say prediction markets are fine, others say the opposite. It’s creating confusion on all sides. At this point, it might take the Supreme Court to settle this for everyone involved….
