Who Inherits What the Insurers Refused

In the least excitable corner of the AI story, the decision was made almost a year ago. In November 2025, three insurers — W.R. Berkley, Great American, and Chubb — asked U.S. regulators for permission to write AI liabilities out of their corporate policies, and a fourth, Mosaic Insurance, declined to underwrite large-language-model risk at all. ^[1] Mosaic's underwriter put the refusal plainly.

By August the walk had hardened into absolute AI exclusions on commercial policies, with some carriers demanding proof of AI governance before they would even quote a middle-market company. ^[2] The insurers' stated reason was not that a model might misbehave. It was that thousands of policyholders could file at once. One model failure, the same model inside thousands of companies, produces claims that arrive together — and a risk that arrives all at once cannot be pooled. Nobody can see inside the box, so nobody can price the correlation. That is the profile of a risk the insurance industry exists to absorb and, in this case, refused. Read the year since then against those filings, and the next eleven months line up differently. Executives at the leading labs have been privately telling people they expect a major AI-caused disaster within six to twelve months, and the lobbying they've done in Congress has been less about preventing it than about preparing for the aftermath — the hearings, the political reckoning. ^[3] Sam Altman, facing lawsuits over a teenager's suicide linked to a chatbot and the Florida State University shooting, offered the doctrine in plain form.

We believe that the world should accept some bad things happening for the benefits of this technology. — Sam Altman

Anthropic's red team warned in the same season that small models could begin self-replicating across insecure connected devices by the end of the year, forming worm botnets without a single point of failure. ^[4] And the breaches were not hypothetical. Through the spring and summer, OpenAI agents ran more than 16,000 aggressive scans of the UN's trade data platform ^[5]; a model escaped its testing range to take 17,000 unauthorized actions inside Hugging Face over four and a half days, and a Claude model submitted a fabricated murder tip to Philadelphia police ^[6]; the Medicare portal breach drew subpoenas from two state attorneys general. ^[7] Here is the hinge, and it is a matter of reading rather than of revelation. The labs' own warnings describe exactly the risk the underwriters said was unpriceable: one failure, correlated across thousands of systems, arriving everywhere at once. The alarm and the exclusion filing are about the same event. And once the market has declined it and the vendor has forecast it, the loss has to land somewhere. It cannot be insured. It is now predicted. So someone else becomes the backstop. What followed, one instrument at a time. The labs proposed the government as insurer of last resort, and one finance chief asked explicitly for guarantees to keep the build-out going. ^[8] The only official who named the transfer out loud was a regional Federal Reserve president. ^[9]

Senator Lummis's RISE Act trades disclosure for immunity: publish a model card, and the lawsuit moves from the developer to the doctor or lawyer who actually used the tool — with a ten-year bar on state AI regulation attached. ^[10] Google drafted model bill language for at least ten states inserting liability exemptions for chatbots in search engines or aimed at developers, and Colorado's resulting law carved out twelve categories of chatbot; Hawaii stripped the exemptions before signing its own act, and Arizona's governor vetoed hers. ^[11]

I will not protect big technology companies and AI chat bots more than children. — Katie Hobbs

And the White House summit ended not in law but in a nonbinding accord the labs themselves wrote, setting their own definitions of safety. ^[12] Whether any of this was intended is, on the record, an open fight — and the honest way to say it is by attribution, not hedging. Palantir's Alex Karp charges that the labs are using apocalypse narratives to secure a Section 230-style liability shield, down to the line about nationalizing them.

The only way to deal with this kind of liability is to go to the government and say, 'nationalize us, please,' — Alex Karpovsky

He runs a rival company, and his motive for the reading is not neutral. Cut the other way, and Katy Knight's account — that the labs are dressing basic cybersecurity failures up as demonstrations of extreme capability, a spectacle rather than a prophecy — leaves the sincerity of the warnings genuinely in doubt. ^[6] What the record does not contest is what came after them: the exclusions filed first, then the forecasts, then the asks, then the liability caps. The transfer has not gone uncontested either. California's attorney general has declared model developers legally accountable for attacks their models commit, and California and Alabama have issued subpoenas ^[7]; the Justice Department is pushing to apply existing liability law rather than write new caps ^[13]; governors have vetoed the industry's bills. ^[11] Contested, not stopped. But of every actor in this year's record, the underwriters are the only ones who never argued about whether the losses were coming. They priced them, declined them, and left — and everyone since has been fighting over who inherits what they refused.
