California Governor Gavin Newsom signs sweepstakes ban

Summary

Governor Gavin Newsom signed Assembly Bill 831 on 11 October 2025, outlawing sweepstakes-style gambling in California. The law not only targets sweepstakes operators but also extends penalties to suppliers, affiliates and other partners who support the platforms. The bill moved through the state legislature without opposition and is the most significant regulatory action against the sweepstakes vertical since public scrutiny increased in late 2024.

The campaign to ban sweeps was driven by traditional gambling interests, notably California’s gaming tribes. The move follows legal pressure, supplier exits and warnings from industry bodies about broad economic consequences.

Key Points

AB 831, signed on 11 October 2025, bans sweepstakes gambling in California.
Penalties reach beyond operators to include suppliers, affiliates and other partners.
The bill passed unanimously through the legislature, facing no recorded votes against it.
The push was coordinated by established gambling interests, particularly California gaming tribes.
Industry groups warn of substantial economic impact; SGLA-commissioned research estimates up to a $1bn hit to California.
Major suppliers such as Evolution, Hacksaw and Pragmatic Play have already exited the state amid legal action.
California now joins six other states with sweepstakes bans; further bills are pending in other jurisdictions.

Context and relevance

This is a watershed moment for the US sweepstakes model. With California — the largest US market by population — banning the vertical, operators and suppliers face heightened regulatory risk and likely business-model reassessment. Expect continued legal challenges, consolidation among trade groups and spillover regulatory activity in other states. For anyone involved in iGaming, payments, compliance or affiliate marketing, this materially raises the bar for risk management and strategic planning.
