Four tribes launch Kalshi prediction-market apps as Cabazon challenges reach of courts

Four Native American tribes launched Kalshi-backed prediction-market apps on Wednesday, seeking new revenue streams and framing the moves as exercises in tribal sovereignty and economic self-determination. One day earlier the Cabazon Band of Cahuilla Indians filed an amicus brief urging the United States Supreme Court to hear New Jersey v. Kalshi and reverse a Third Circuit ruling that Cabazon says threatens tribal authority over gaming on reservation lands.

Four tribal apps go live on Kalshi's exchange

Three of the new apps come from California tribes: the Kletsel Dehe Wintun Nation (southwestern Colusa County) launched Sovereign Edge; Greenville Rancheria (northern California) launched Greenville; and the Alturas Indian Rancheria (northeastern California) launched AIR Markets. The Alabama-Quassarte Tribal Town, based in Wetumka, Oklahoma, launched PokkeTrades. All four apps are powered by Kalshi’s exchange infrastructure and were reported by CNN and Fortune.

For Kletsel Dehe administrator Eric Wright the decision is tied to immediate economic need: the reservation lacks potable drinking water, and Wright said he hopes revenue from the app can help fund water projects. Wright told CNN, “We aren’t a big gaming tribe that has a ton of economic dollars lying around. At its core, this is about tribal sovereignty and economic self-determination.”

Michael Stopp, a Cherokee businessman who advised Alabama-Quassarte on its app, said his company vetted Kalshi’s programme and found it credible. “I didn’t want to just be the redface out there,” Stopp told CNN. “They’ve put together a very good program for these tribes. It is a legitimate opportunity.”

The tribal launches follow the Tunica-Biloxi Tribe of Louisiana introducing SaltTrade Derivatives, the first tribal-owned prediction-market app powered by Kalshi, less than a month earlier. Tunica-Biloxi Tribal Chairman Marshall Pierite told CNN other tribal leaders have asked how they could replicate that model.

Cabazon's Supreme Court brief frames the opposite sovereignty claim

The Cabazon Band of Cahuilla Indians filed a brief asking the Supreme Court to take New Jersey v. Kalshi and overturn the Third Circuit decision that sided with Kalshi in April. Cabazon says that decision would displace the tribal, state and federal gaming framework under the Indian Gaming Regulatory Act (IGRA) by placing Kalshi’s sports-event contracts under the Commodity Futures Trading Commission (CFTC).

Cabazon framed its filing through its historical role in tribal gaming. The tribe was at the centre of California v. Cabazon Band of Mission Indians, the 1987 Supreme Court case that led to Congress passing IGRA in 1988. The brief states: “As the tribe whose actions ‘opened the door’ for tribal gaming, the Cabazon Band is uniquely positioned to draw the Court’s attention to this critical situation.”

Cabazon’s Legal Affairs Director Jonathan Rosser said in a sworn declaration that he downloaded the Kalshi app from his office on the reservation on Sept. 22 and placed a $25 trade on the Minnesota Vikings–Tampa Bay Buccaneers game. Cabazon Tribal Gaming Commission Executive Director Jose Escobar Rivera said that trade violated the tribe’s federally approved gaming ordinance, breached its compact with California and was unlawful under IGRA. The brief argues those violations are occurring now on tribal land and that the Third Circuit ruling threatens tribes’ exclusive right to regulate gaming activity on Indian lands.

The legal split: Third Circuit versus two Ninth Circuit panels

The dispute turns on whether Kalshi’s sports contracts fall exclusively under federal commodities law and CFTC jurisdiction or whether they are subject to state and tribal gaming regulation under IGRA. The Third Circuit concluded in April that New Jersey cannot enforce its sports-wagering laws against Kalshi’s contracts, a ruling Kalshi welcomed and New Jersey sought Supreme Court review of.

Two Ninth Circuit panels have reached the opposite conclusion. In KalshiEX v. Assad (August) a panel allowed Nevada to enforce its gaming laws against Kalshi’s sports contracts, finding those contracts likely are not swaps under the Commodity Exchange Act. In Blue Lake Rancheria v. Kalshi (September) another Ninth Circuit panel sided with two California tribes, finding they were likely to succeed on the claim that Kalshi’s activity constitutes gaming governed by IGRA. The Ninth Circuit decisions emphasised the customer’s location on tribal land rather than the physical location of Kalshi’s exchange infrastructure.

Cabazon cited both Ninth Circuit rulings in its brief to the Supreme Court and argued the circuit split makes resolution by the justices necessary. Kalshi has been granted an extension to respond to New Jersey’s petition; the company’s response is due Nov. 9.

What this means for tribes and operators

Tribes partnering with Kalshi view the technology as freedom to pursue new revenue and diversify economic activity on their lands. For some tribal leaders, app launches are explicitly tied to infrastructure and community needs: Kletsel Dehe wants app proceeds to support water projects.

Other tribes see Kalshi’s presence as an intrusion on their regulatory authority. Cabazon’s filing shows how that conflict plays out: the tribe says its gaming ordinance and compact prohibit mobile sports betting on its reservation, yet Kalshi’s contracts were accessible there.

The broader practical consequence is a patchwork environment for operators and platform partners where the legal status of prediction-market contracts varies by circuit and by whether a tribe chooses to licence or prohibit the activity. As the Supreme Court considers whether to take New Jersey v. Kalshi, the question will play out tribe by tribe: some will build on Kalshi’s exchange, others will document trades on reservations as violations of tribal and federal law.

Legal and industry implications for prediction markets and regulators

The Supreme Court’s decision whether to grant review in New Jersey v. Kalshi will determine whether the Third Circuit’s reasoning becomes national precedent or whether the Ninth Circuit’s two rulings carry weight in other jurisdictions. The outcome affects who has enforcement power — the Commodity Futures Trading Commission or states and tribal gaming authorities operating under IGRA.

Industry participants and regulators are watching the timeline closely. Kalshi’s response to the petition is due Nov. 9, and until the justices either grant review or deny the petition the jurisdictional conflict will remain unresolved. Operators building tribal apps must weigh revenue prospects against regulatory exposure while tribes decide whether to partner or litigate.

“These violations are occurring at this moment,” Cabazon told the Supreme Court in its brief, describing trades on its reservation as active breaches of tribal ordinances. — Cabazon Band of Cahuilla Indians

For platforms and vendors offering services to tribes, the split means commercial opportunities will exist in some jurisdictions and legal risk in others. Tribal choices will determine where prediction markets expand and where regulators intervene.
