As of my last update in early 2023, sports betting in California was not fully legalized for online or retail betting. However, there were efforts to legalize sports betting through ballot measures, which would require a change to the state constitution since gambling is heavily regulated in California.

Specifically, there were two proposed initiatives for the November 2022 ballot that aimed to legalize sports betting:

1. Proposition 26, which would have allowed tribal casinos and horse racing tracks to offer sports betting, both in-person and online through tribal platforms.

2. Proposition 27, which would have allowed online sports betting through companies that were not associated with tribes or horse racing tracks.

Both propositions were defeated by California voters, meaning that as of the last update, sports betting remains illegal in California outside of certain forms of legal gambling already permitted by the state, such as horse racing and certain types of betting at tribal casinos.

It’s important to note that the legal landscape surrounding gambling and sports betting can change rapidly. For the most current information, you should check with the California Gambling Control Commission or refer to the latest state laws and regulations.
