California has officially outlawed sweepstakes-style casinos, becoming the largest US state to ban such platforms. Governor Gavin Newsom signed Assembly Bill 831 (AB 831) into law on Saturday, marking a decisive moment in the growing clampdown on unregulated gaming across the United States. The law takes effect on 1 January 2026.
The legislation passed unanimously through both the California State Assembly and State Senate, reflecting rare bipartisan agreement on gambling regulation. It prohibits sweepstakes operators, as well as any third-party entities involved in facilitating their operations. That includes payment processors, geolocation providers, platform suppliers, financial institutions, and even media affiliates. Those found in breach of the new law could face fines of up to $25,000, a year in county jail, or both.
Clashing Interests
The California Nations Indian Gaming Association (CNIGA) was a key supporter of the bill. The group maintained that sweepstakes-style casinos infringed on tribal exclusivity rights, which grant California’s tribes sole authority to operate most forms of gaming within the state.
CNIGA argued that the measure was necessary to preserve a regulated, transparent, and fair gaming environment. From their perspective, unlicensed sweepstakes operators undermined both consumer protections and the integrity of the state’s tribal gaming framework.
On the flip side, the Social Gaming Leadership Alliance (SGLA), which represents sweepstakes casino operators, strongly opposed the legislation. The alliance urged the governor to veto the bill, claiming it would remove a billion dollars’ worth of annual economic activity from California’s economy and harm digital innovation in the gaming space.
SGLA leadership argued that banning the sector could worsen economic disparities among tribal communities and cost the state hundreds of millions in potential tax revenue. The group cited research suggesting that most Californians would have preferred the state to regulate and tax sweepstakes casinos rather than prohibit them altogether. Despite these warnings, the governor’s approval signalled broad political consensus that the risks posed by unregulated sweepstakes platforms outweighed potential economic benefits.
A Growing Trend
California’s move comes amid a broader national trend of US states taking action against sweepstakes-style gaming. Montana, Connecticut, and New Jersey have already effected bans, while similar measures in New York and Nevada are awaiting gubernatorial approval.
Beyond that, it sheds more light on the growing regulatory caution seen in other markets. That includes the UK, where the Gambling Commission has tightened its stance on white-label and social gaming models that blur the line between gambling and casual play.
