Prop 27 and its Flawed Approach to Mobile Sports Betting
30 October 2026
California's latest push for mobile sports betting is shifting from the ballot to the halls of Congress, as tribes fight to preserve their dominance in the growing market. In 2022, voters overwhelmingly rejected twin ballot measures - Proposition 26, backed by tribes, and Proposition 27, pushed by out-of-state gaming companies - that would have legalized sports betting.
The 2022 Propositions
A look back at Prop 27: Backers spent $169 million to pass a 15% tax on their potential revenue. Consider this: Proposition 27, which lost by 82% to 18%, would have allowed bets on sports events and some non-sporting competitions, while banning wagers on high school games and elections. It would have permitted tribes with tribal-state agreements and certain gambling operators to apply for five-year licenses to offer online sports betting to California adults 21 and older. Licensed companies would have paid the state significant annual fees for regulation and homelessness programs.
Why the Tribes Care
The tribes are now focused on blocking any federal legislation that might weaken their established control over gambling. They sent a letter to U.S. Senate leaders requesting a complete prohibition on sports and casino-style prediction markets, along with protective clauses for tribal gaming rights. Their letter states: "No bill, including the CLARITY Act, should override or diminish the Indian Gaming Regulatory Act, tribal-state agreements, state gaming laws, or tribal gaming regulations."
Tribal leaders have also proposed putting their own sports betting measure on the 2028 ballot, stressing a "tribally-led, tribally-operated, tribally-owned" model to prevent the destructive conflicts of 2022, when competing initiatives spent $470 million combined. Regardless of success, it's evident that for all parties - commercial entities and tribes alike - California's lucrative market comes at a steep cost.
The Feds Weigh In
Dominating the discussion is the CLARITY Act, stalled in the Senate for years, which would establish federal standards for digital currencies. Currently, supporters lack enough Republican votes for passage, while opponents warn about potential loopholes for online gambling. Before changing strategies, cautious observers might wait for more definite developments.
Looking to the Horizon
The political momentum has shifted against gambling reformers, as tribal leaders in California are working to secure support for their own sports betting proposal on the 2028 ballot. Behind closed doors, the California Nations Indian Gaming Association (CNIGA) has been developing an infrastructure investment plan. Their objective: to prevent another expensive, contentious fight like the one that characterized the 2022 election.
The tribes have an alternative strategy: their own sports betting initiative for 2028. In this scenario, commercial providers would handle the technology, while the tribe or tribal casino would serve as the public brand. The aim is to avoid repeating the $470 million expense of 2022 while guaranteeing tribes a share of what could become a billion-dollar industry. By influencing the market now, when political conditions are favorable, the tribes seek to secure lasting advantages from a prosperous betting sector on their preferred terms.
