But California’s gaming tribes aren’t on board, and it’s unclear who’s bankrolling the effort. Proponents have filed with the state Attorney General’s Office to launch a pair of proposed measures for the November 2024 ballot that would allow on-site and online sports betting in California through the state’s recognized Indian tribes.
