California's Tribes Asked Sportsbooks for Terms on a 2028 Ballot Initiative

A confidential CNIGA request for information dated 3 June, obtained by InGame, sets out seven principles for a tribally owned online sports betting market, three market structures with a single tribal consortium on top, a 10% to 25% state share, and a "protect against iGaming" clause. Selected respondents are being met now.

• The California Nations Indian Gaming Association issued a nine-page request for information to prospective vendors and partners on 3 June, with submissions due 1 July, a working-group review in July and August, and meetings with "selected respondents" now under way, according to the document obtained by InGame
• Seven principles govern the initiative CNIGA is shaping for the 2028 ballot: tribally led, driven and owned; protect tribal sovereignty; preserve tribal gaming exclusivity; benefit all California tribes; prioritise funding for Revenue Sharing Trust Fund tribes; governed by the Indian Gaming Regulatory Act; and "protect against iGaming"
• Three market structures are on the table, each with a single tribal consortium owned by all California tribes at the top: one exclusive white-label platform, multiple tribal-branded platforms with commercial back ends, or multiple platforms including commercial and co-branded front ends
• The RFI presumes an IGRA model in which tribes hold the licences, partners pay tribes 60% of revenue, bets are deemed placed where the server sits on Indian land, and the state receives 10% to 25% of net gaming revenue; tribes retain ownership of their own data
• Respondents were asked for commercial terms, contract length, technology, responsible gambling tools, and what they would pay towards ballot costs, licensing and marketing in years one to five

The Tribes Are Writing the Market and Asking the Operators What They Will Pay for It

California's tribal gaming association has moved from opposing commercial sports betting to specifying it. A request for information issued by the California Nations Indian Gaming Association (CNIGA) on 3 June, and obtained by InGame late last week, invites "input from prospective Vendors and Partners" on an online sports betting initiative for the 2028 ballot. Submissions were due on 1 July; a CNIGA working group reviewed them through July and August; and the calendar in the document has the association meeting selected respondents now. Which companies replied, and which were invited back, is not stated.

The nine-page document lists seven principles that will shape the measure: tribally led, tribally driven, tribally owned; protect tribal sovereignty; preserve tribal gaming exclusivity; benefit all California tribes; prioritise funding for tribes eligible for the Revenue Sharing Trust Fund, the non-gaming and limited-gaming tribes; governed by the Indian Gaming Regulatory Act; and protect against iGaming. CNIGA represents more than 50 of the state's 109 tribes, including its largest gaming tribes.

Every structure it describes has the same top. A single tribal consortium, wholly owned and governed by all California tribes, would hold the market and make profit-share distributions to tribes. Below it, three options: a single exclusive white-label platform licensed and operated by the consortium, the document's example being a CaliforniaBets.com; multiple platforms restricted to brands owned and operated by tribal nations, with commercial operators supplying back-end services but no front-facing brand; or multiple platforms in which commercial operators may negotiate with a partner tribe to be the front-facing or co-branded name. None of the three covers in-person wagering, which gaming tribes can offer under their compacts.

The legal architecture is Florida's. The RFI presumes an IGRA model, under which tribes own the betting licences and operating partners pay tribes 60% of revenue, and states that the initiative will include what InGame calls the "magic language": the jurisdictional location of a bet is the physical location of the server, which must be on Indian land. That formulation, in the Seminole Tribe's compact with Florida, produced a statewide monopoly for Hard Rock Bet, the only operator live there since November 2023. Any IGRA partnership requires approval by the National Indian Gaming Commission. The RFI proposes the state receive 10% to 25% of net gaming revenue, and that tribes retain ownership of their own data even where third parties collect it.

Respondents were asked for commercial terms under any scenario they would consider, including revenue or profit share and what costs they would deduct, minimum contract length, whether their technology is in-house or outsourced, and a detailed account of responsible gambling tools: detection, intervention, self-exclusion, affordability checks, marketing restrictions and research funding. They were also asked what they would contribute towards the cost of the ballot initiative itself, and what they would pay in licence or contract fees and marketing in each of years one to five.

The context is 2022, when a commercial coalition's online sports betting initiative suffered the worst defeat in state history and Indian Country spent $250 million to ensure it. Some operators have since apologised for overstepping, InGame notes, and conversations have continued, but nothing as direct as CNIGA asking the industry for terms. This month's Ninth Circuit ruling that Kalshi's sports contracts are Class III gaming on tribal land, and CNIGA chair James Siva's remark that the tribes are "keeping track" of which operators entered prediction markets, are the other half of the picture.

"Protect Against iGaming" Is a Sequencing Clause, Not a Prohibition

Online casino can produce more than ten times the tax revenue of online sports betting in states that have both, and the industry treats sports as the opening act. Read literally, CNIGA's seventh principle keeps that act from ever starting. Read with the three structures in mind, it keeps commercial brands out of the room when it does: a tribal consortium that owns the licences, the servers and the customer data can add casino games to its own white-label platforms whenever it chooses, and the RFI's data-ownership clause is the tell. The principle protects tribes against commercial iGaming, which is a different thing from protecting Californians against iGaming, and the operators who answered the RFI will have understood the difference.

The Operators Are Being Asked to Fund a Ballot That Gives Them No Brand

Two of the three structures put a tribal name on every app Californians would see, and the RFI asks respondents how much they would pay towards the initiative, the licences and the marketing regardless. That is the Florida bargain offered statewide: technology, trading and risk in exchange for a revenue share, with the consumer relationship owned by the tribe. DraftKings and FanDuel learned in 2022, against $250 million of tribal opposition, that California cannot be won against Indian Country; the RFI tests whether they will pay again to be a supplier to it. The third structure, co-branding, which InGame likens to a title sponsorship on a stadium, is the concession on offer, and the price of it will have been the substance of the meetings now taking place.

Prediction Markets Have Made the Tribes' Timetable Urgent and Their Leverage Larger

In June, when the RFI went out, Kalshi and Polymarket were taking sports bets from Californians under a federal registration with no tribal share at all, and by September the Ninth Circuit had said that on tribal land that is Class III gaming. A 2028 initiative that puts every legal online bet in the state on a tribal server is the tribes' answer to both the commercial operators and the exchanges, and Siva's ledger of who went into prediction markets is the list of who will find the consortium's door harder to open. The RFI asks operators to describe their responsible gambling programmes at length; it does not ask about their event-contract businesses, and it will not need to.

California's tribes have a document, a timetable and a set of applicants. The commercial industry has a choice between being a supplier to the largest state in the country and being absent from it, which is a narrower choice than it had in 2022.
