Major League Baseball is the first major sports league to back an initiative that would allow online sports betting in California.

There are two initiatives on the ballot. Only tribal casinos and horse racing tracks would be allowed to accept in-person bets. Online sports betting could be allowed by the proposition.

The California Solutions to Homeless and Mental Health Act is supported by Major League Baseball. It is supported by a group of operators. The homeless crisis in California would be funded by a percentage of the revenue from the referendum.

Major League Baseball has an official betting partner in DraftKings and FanDuel. MLB has advocated for sports betting legalization since the Supreme Court struck down the Professional and Amateur Sports Protection Act of 1992.

MLB is committed to protecting the integrity of its games and creating a safe experience for fans who wish to wager on those games, as legalized sports betting continues to expand across the country. Proposition 27 is the only measure on California's upcoming ballot that would authorize and regulate online sports betting.

The measure would require sports book operators to notify leagues of suspicious wagering activity, allow leagues to propose restrictions on betting markets that are susceptible to manipulation, and facilitate other forms of integrity- related cooperation between the state, leagues, and operators. With millions of MLB fans looking for alternatives to illegal offshore betting sites, MLB believes that Prop 27 will create a safe and responsible online sports betting market in California.

The California Sports Wagering Regulation and Unlawful Gambling Enforcement Act is supported by a group of tribes.

A large and growing coalition of Indian Tribes, social justice advocates, teachers, parents, homeless and mental health advocates, business, public safety and labor leaders all oppose Prop 27. Every cell phone, laptop, gaming console and tablet will be turned into a gambling device if the measure passes. There is no way to make sure kids don't gamble online. The out-of-state gambling corporations funding Prop 27 wrote it so they could take most of the profits from other states. Voters will reject this measure in the fall.

According to Chris Gove, an investor in the sports betting space, a mature online sports betting market in California could bring in as much as $3 billion in revenue annually. By the fifth year, retail-only sports betting would have generated $356 million in gross revenue.
