It’s a high-stakes battle when it comes to legalizing a form of sports betting in the Golden State. A coalition of more than 40 California tribes is backing a move that would legalize in-person sports betting on tribal lands. Another would legalize online sports betting. Proponents argue that the ballot measure will fund homelessness and mental health solutions each year. Gambling industry experts believe that by marking the Golden State, California would be the crown jewel of the legal sports betting market in the United States. They say that if online and in-person sports gambling is legalized, California voters could open up a market worth more than $3 billion in annual revenue.
