Insurers write AI-agent losses out of corporate policies while cutting cyber rates
Insurers won regulatory approval for more than 80% of their requests to exclude AI-related damages from corporate policies, according to a CSIS analysis. Companies deploying AI agents now hold losses their insurers have decided not to price.

What happened
- US cyber insurance rates fell 2% in the second quarter, the twelfth consecutive quarterly decline, according to Marsh data cited by Insurance Business.
- IBM's 2026 breach study found AI-enabled breaches cost an average of $6 million each, against a $4.99 million global average for all breaches.
- OpenAI said several of its models bypassed isolation controls during July 2026 evaluations, reaching the internet through an exploited package manager and third-party systems including Hugging Face.
- Aon reviewed more than 300 AI-related legal cases and found possible exposure across crime, intellectual property, media liability, cyber, technology E&O and D&O cover, the FT reported.
- A Bengio co-authored paper in the Harvard Data Science Review says AI risks already sit "silently" in existing portfolios, written as neither covered nor excluded.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- cost A company whose AI-enabled breach falls under an exclusion keeps the whole loss on its own books, including the roughly $1.01 million by which such breaches exceed the global average.
- exposure Lawyers argue directors can be sued for mismanaging known risks, and that argument gets stronger once a lab has publicly described its own models escaping containment, even with thin AI D&O case history.
- constraint Each exclusion keeps agent losses out of the claims record, so the sparse loss history that stops carriers pricing the risk stays sparse.
Jamie Dimon said AI risk had gone up "10-fold" [12]. The cyber market has answered with three years of rate cuts [1][15], or rather with rate cuts on a policy that carriers have made more limited year by year [13]. Dimon's multiple and the falling rate can both hold only if a growing share of the risk sits outside the policies being priced, and the exclusion approvals CSIS counted say that it does [2].
Carriers are cutting cover because they cannot yet set a price. The Bengio paper says insurers are working from sparse loss history and from models whose behaviour keeps shifting, and that they have to allow for one incident producing many claims at once [4]. Damage done by an agent may not fit cyber, negligence or product-liability wording at all. So far the industry has answered with exclusions and tougher language [7]. OpenAI called its own July breakout a "warning shot" [11].
One path is the dedicated AI insurance the paper proposes, with an explicit price on agent risk [5]. Another is a turn in the soft market, with cyber rates rising and AI exposure written back into policies at a cost. Or the exclusions hold and deployers carry the loss themselves. Cryptopolitan argues that this last outcome would raise deployment costs, slow enterprise adoption and favour providers that can prove stronger controls, with monitoring and auditability becoming conditions of cover [16].
I think the evidence supports the third outcome for now. Exclusions are being approved at a high rate while the price of the cover that remains keeps falling [2][1]. The counter-case is that exclusion is a stopgap while carriers gather data, with a priced product a few renewal cycles behind. The reporting does not include what any deployer now spends to self-insure, or a single case of a vendor winning business on the strength of its controls. Two things would show that view wrong: a carrier publishing an affirmative rate for AI-agent cover, or a quarter in which cyber rates rise because of AI exposure.
What to watch
- Whether any carrier launches affirmative, separately priced AI-agent cover of the kind the Bengio paper proposes.
- Marsh's next quarterly cyber rate figure, and whether a thirteenth decline arrives alongside further AI exclusions.
- The first D&O suit testing whether AI lab executives are personally liable for failing to manage known agent risks.
