Gaming Edge’s TL;DR
- California tribes are eyeing 2028 to get a measure on the ballot legalizing online sports betting.
- The proposal would have the tribes control it exclusively.
Tribal leaders say they are aiming for a 2028 ballot measure to legalize California online sports betting, with a tribal-led model centered on regulation, taxation, age verification, and tribal exclusivity.
The plan also positions tribes against prediction markets and any renewed push from commercial sportsbook operators.
California Nations Indian Gaming Association (CNIGA) Chair James Siva said tribes are targeting the 2028 election to bring online sports betting back to voters in the nation’s largest unresolved betting market.
Speaking on the “New Normal” podcast with Indian Gaming Association Conference Chair Victor Rocha and Executive Director Jason Giles, Siva said:
“I will say it verbatim – 2028 is the goal.”
He described the effort as a data-driven campaign built on continued polling and a long runway to organize support.
Tribal exclusivity
Siva said California tribes want a system that keeps sports betting under a tribal-led framework. That model would emphasize safe and regulated wagering, tax revenue, age verification for customers 21 and older, and protections for tribal exclusivity and sovereignty.
The timeline reflects lessons from 2022, when California voters rejected two competing sports betting propositions after a costly campaign. Tribes had backed Proposition 26, while major sportsbooks supported Proposition 27.
Siva said tribes viewed the defeat of the commercial measure as especially important, noting that Proposition 27 drew 83% opposition.
“We’re trying to do something that’s data driven.”
He added that tribes have continued polling, including as recently as June. According to Siva, that research shows Californians generally hold favorable views of tribal gaming and trust tribes to offer “safe and regulated gaming” while giving back to communities.
Prediction markets a factor
A major part of the tribes’ message is likely to focus on the contrast with prediction markets. Siva pointed to platforms such as Kalshi and argued that a tribal sports betting model would produce jobs, taxes, and local benefits, unlike those products. He also said tribal betting would use 21-plus age verification, while prediction markets accept participants ages 18 to 20.
Siva further claimed that 60% of Californians in recent polling believed online sports betting is already legal in the state, which he attributed to the growing visibility of prediction market products.
“That’s why 2028 is so important.”
For now, several key details remain unresolved, including the final wording of any ballot measure, which tribal groups beyond CNIGA would formally join the effort, and whether a 2028 proposal would cover only online betting or retail wagering as well.
What is clear is that California tribes are already framing the next sports betting fight as a choice between a regulated tribal model and outside alternatives. If that campaign makes the ballot, it could become one of the most consequential US gambling policy battles of 2028.
