Gov. Newsom signs California sweepstakes casinos prohibition

Summary

Governor Gavin Newsom has signed Assembly Bill 831, banning dual-currency sweepstakes casinos in California. The law — effective 1 January 2026 — outlaws platforms that use a combination of non-monetary and redeemable “sweeps” currencies to mimic online casinos and sports betting.

The move, passed unanimously by the California Legislature, is expected to remove roughly 20% of US sweepstakes-industry revenue, according to industry analysts. California joins several other states that have recently acted against unregulated sweepstakes platforms, and regulatory and legal pressure (including a Los Angeles City Attorney lawsuit against Stake.us) has prompted suppliers and partners to exit the market.

Market forecasters have already adjusted estimates: Eilers & Krejcik trimmed its 2025 US sweepstakes revenue forecast from $4.7bn to $4bn and predicts a further contraction in 2026.

Key Points

Assembly Bill 831 bans dual-currency sweepstakes casinos in California, effective 1 January 2026.
The California Legislature approved the bill unanimously; Governor Newsom signed it just before the deadline.
Analysts estimate the measure will eliminate around 20% of the sweepstakes industry’s US revenue.
Los Angeles City Attorney filed a lawsuit against Stake.us earlier this year, accusing it of operating an illegal gambling site.
Suppliers and streaming partners have been a critical pressure point; many left the market after legal action began.
Several other states (Connecticut, Montana, New Jersey and others) have enacted bans or regulatory crackdowns, with New York and Louisiana taking related actions.
Industry revenue estimates have been revised downward and further declines are forecast for 2026.

Context and relevance

This is the largest single-state regulatory blow to the sweepstakes-casino business model so far. California — the biggest US market by population and commercial scale — closing this loophole signals momentum for national enforcement and hardens the operating environment for unregulated platforms, payment processors, streaming partners and affiliates.

For operators, suppliers and investors, the rule change alters risk calculations: compliance costs, contracting with licensors and content partners, payment rails and customer acquisition strategies will all feel the impact. For regulators and consumer-protection advocates, the law is a high-profile example of states moving to close perceived exploitative gaming loopholes.

Why should I read this?

Short answer: because this is big and fast-moving. California just dealt a major blow to a $4bn-ish industry — if you’re in gaming, payments, streaming, affiliate marketing or regulation, this changes revenue, partnerships and legal risk.
