SB 1050, Sen. Angelique Ashby’s synthetic-performer disclosure bill, cleared the Senate and advanced out of Assembly Appropriations, positioning it for a final Assembly floor vote before the Aug. 31 adjournment. The Senate passed it 38-0 on May 28; Assembly Appropriations followed 12-1 on August 13, according to LegiScan’s history. The Transparency Coalition’s August 28 update confirms Newsom has 30 days after the scheduled August 31 adjournment to sign or veto, putting decision day in mid-to-late October.

The mechanics are narrow and sharp. It becomes unlawful to publish an ad that “prominently includes a synthetic performer” in the California market without a “clear and conspicuous disclosure” reading either “this performance features a synthetic performer” or “no human performer is depicted.” “Prominently” covers foreground demonstration, on- or off-camera narration, and any performer reacting to the commercial message. “Clear and conspicuous” is defined as “difficult to miss, easily understandable” in context.

The teeth are borrowed, not new. The Senate Judiciary analysis notes SB 1050 expressly preserves remedies under Bus. & Prof. Code §17500 (False Advertising Law) and §17200 (Unfair Competition Law), meaning civil enforcement and restitution attach to noncompliant creative the moment it runs.

For a 5-to-30-person B2C brand cranking out Reels with an AI voiceover or a synthetic mascot, a hashtag buried in caption text almost certainly won’t clear the bar. This is the third overlapping regime landing in a single year, following SB 1050’s path to Newsom’s desk and the 24-bill AI package moving in seven days we tracked alongside a five-day countdown filed earlier this week. New York’s synthetic-performer law took effect June 9, 2026, and the EU AI Act’s Article 50 transparency duties applied August 2, per Dynamis LLP.

Synthetic talent got cheap first. The disclosure regime is catching up in three jurisdictions at once, and the smallest advertisers are the ones with the least legal cushion when it does.
