California AB 831: What the Sweepstakes Casino Ban Means for Players & Vendors

On October 11, 2025, California Governor Gavin Newsom signed Assembly Bill 831 into law, banning sweepstakes casinos statewide effective January 1, 2026. The bill passed with zero opposition — a rarity in Sacramento for legislation of this scope. AB 831 did not just prohibit operators from serving California residents. It extended criminal liability to the entire vendor ecosystem that supports sweepstakes casino operations, from payment processors to geolocation providers. Unanimous and unprecedented, it set a template that other states are now actively studying.

For players, AB 831 meant immediate loss of access to every sweepstakes casino platform that had been accepting California users. For the industry, it meant losing the single largest state market in the country. And for vendors who provide infrastructure services to sweepstakes operators, it introduced personal criminal exposure that had no precedent in sweepstakes regulation. Understanding what AB 831 actually says — not what headlines summarized — is essential for anyone following the regulatory trajectory of the sweepstakes casino market.

What AB 831 Prohibits

AB 831 prohibits the operation, promotion, and facilitation of sweepstakes casinos within California. The law defines a sweepstakes casino as any online platform that uses a dual-currency system — Gold Coins and Sweeps Coins or their equivalents — to offer casino-style games where the promotional currency can be redeemed for cash or prizes. This definition is deliberately broad. It captures the core mechanic that every major sweepstakes casino relies on, leaving little room for operators to restructure around the ban.

The legislative path to AB 831 was remarkably smooth. The bill passed the California State Senate 36-0 and the Assembly 79-0, making California the 17th state to ban sweepstakes casinos, as documented in the California legislative record. That unanimous vote is notable because California’s legislature rarely agrees on anything related to gambling. The state has a complex history with gaming interests — tribal casinos, card rooms, the lottery, and repeated failed attempts at sports betting legalization have all produced deep political divisions. On sweepstakes casinos, those divisions vanished.

The ban applies to any entity that operates a sweepstakes casino accessible to California residents, regardless of where the operator is incorporated or where its servers are located. An operator based in Malta running servers in Ireland that accepts a player with a California IP address is in violation. The enforcement mechanism relies on a combination of geolocation blocking — operators must prevent California users from accessing their platforms — and the criminal liability provisions described below.

Violations of AB 831 are classified as misdemeanors, carrying penalties of up to $25,000 in fines and up to one year in county jail per offense. For an industry built on operating from offshore jurisdictions, the personal criminal exposure is a significant escalation from the cease-and-desist letters that had been the primary enforcement tool in other states.

Vendor Liability: Who Else Is Affected

The most significant innovation in AB 831 is not the operator ban itself — seventeen states had already done that. It is the extension of criminal liability to vendors. As detailed in ZwillGen’s legal analysis, AB 831 makes it a misdemeanor for any vendor to knowingly provide services that facilitate a sweepstakes casino’s operations in California. The law specifically names several categories of vendors: payment processors, geolocation service providers, game content suppliers, and media affiliates.

Payment processors are the most directly affected. Any company that processes Gold Coin purchases or Sweeps Coin redemptions for a sweepstakes casino serving California users is potentially liable. This extends to credit card processors, e-wallet services, cryptocurrency payment gateways, and banks that maintain merchant accounts for sweepstakes operators. The practical effect is to create financial infrastructure pressure: if processors face criminal exposure for serving sweepstakes casinos in California, they may choose to drop those clients entirely rather than risk selective enforcement.

Geolocation providers occupy an ironic position. These companies sell the technology that allows operators to block users in restricted states — the very compliance mechanism the industry uses to demonstrate it respects jurisdictional boundaries. Under AB 831, a geolocation provider that enables a sweepstakes casino to operate in states where it is legal could face liability if that same casino fails to adequately block California users. The provider’s product is simultaneously the tool of compliance and a potential source of criminal exposure.

Game content suppliers — the studios that develop and license slot games, table games, and other casino products — are also named. If a provider licenses its games to a sweepstakes casino that serves California, the provider is facilitating the illegal operation. Media affiliates who promote sweepstakes casinos to California audiences face the same risk. This sweeping vendor liability creates a chilling effect that reaches far beyond the operators themselves, touching every company in the supply chain.

Market Impact: $2.42 Billion at Stake

California was not just another state on the sweepstakes casino map. It was the largest. According to an Eilers & Krejcik Gaming report prepared for the SGLA, California generated approximately $2.42 billion in sweepstakes casino sales in 2025 — representing 17.3% of the entire US sweepstakes market. Losing that revenue overnight forced operators to recalculate their financial projections for 2026 and beyond.

The impact was not distributed evenly. The operators behind the largest sweepstakes platforms held the biggest market share in California and absorbed the biggest absolute hit. Smaller operators that had built their growth strategies around California’s massive addressable population faced an even more existential threat: some had allocated the majority of their marketing budgets to acquiring California users, and the ban invalidated those investments entirely.

For California players, the effect was immediate. On January 1, 2026, sweepstakes casino platforms began geoblocking California IP addresses. Players with unredeemed Sweeps Coin balances had to cash out before the deadline or risk losing access to their accounts. Most platforms offered a grace period for pending redemptions in the weeks leading up to the ban, but players who missed the window were left navigating customer support processes that varied in helpfulness from platform to platform.

National Ripple Effect

AB 831’s influence extends well beyond California’s borders. The unanimous vote, the vendor liability provisions, and the speed of implementation have made it a model bill for other states considering similar legislation. Florida, Indiana, and Maine all had pending sweepstakes casino bills as of early 2026, and legislators in those states have cited California’s approach as a reference point.

The financial analysts tracking the sector adjusted their forecasts accordingly. After AB 831 was signed, Eilers & Krejcik Gaming revised their 2025 net revenue projection for the sweepstakes industry from $4.7 billion to approximately $4 billion — still a 16% year-over-year increase, but a meaningful downward correction. Their base-case projection for 2026 assumes a further 10% decline to roughly $3.6 billion in net revenue, driven primarily by the cumulative impact of California, New York, and the states that preceded them.

The vendor liability component may prove to be AB 831’s most lasting contribution. If other states adopt similar provisions, the infrastructure companies that enable sweepstakes casinos — payment networks, geolocation services, game studios — will face a patchwork of criminal exposure that makes serving the industry increasingly risky. Some vendors may exit the sweepstakes space entirely, which would constrain the product quality and operational capacity of remaining platforms. AB 831 was one state’s legislation. Its consequences are reshaping the entire industry.
