U.S. cyber insurers in 2025 reversed a couple of years of decline in direct written premium
s to post growth of 11% but, according to Fitch Ratings, there are some underwriting concerns brought on by developments with artificial intelligence.
Fitch said Anthropic’s Mythos model has raised eyebrows in the financial and cybersecurity worlds. In the short to medium term, vulnerabilities will prob
ably outnumber patches as the artificial intelligence tool works on cyber threat intelligence and incident response.

“AI is particularly disruptive to cyber risk because traditional vulnerability analysis was labor-intensive and offered limited financial upside for researchers, a
gap AI now fills at scale and speed,” said Fitch in its brief on the cyber marketplace on Feb. 15. “This lowers barriers for attackers, expands third-party risks, and could materially increase attack volume.”
Growth in the cyber market was mostly driven by volume, with policies-in-force up 35% to offset soft aggregate pricing. This, said Fitch, indicates a great awa
reness among buyers of cyber exposures, as well as a competitive underwri
ting environment. Larger companies are still more likely to have cyber insurance protection while smaller companies lag behind.
Yet, Fitch said, demand overall has “strengthened as boards and management teams recognize that cyber events can disrupt operations, trigger leg
al liabilities, and impair revenue even when direct financial losses are limited.”

Meanwhile, insurers have and will continue to assess and adjust contract language while integra
ting cybersecurity assessments into underwriting. Policy wordings related to war exclusions, silent cyber, business interruption, an
d contingent losses “will be critical,” added Fitch. A more detailed look at the cyber market is expected this summer, said the credit-rating agency.
Sullivan & Cromwell, a premier Wall Street law firm, apologized to a federal judge for submitt
ing a court filing with inaccurate citations and other errors generated by artificial intelligence.
In a letter dated April 18, Andrew Dietderich, co-head of the firm’s global restructuring group, said the errors included AI “hallucinations” – instances in which AI
makes up case citations, misquotes the law or generates non-existent legal sources.
The mistakes were caught by law firm Boies Schiller Flexner, Dietderich said in the letter
to Martin Glenn, chief judge of the U.S. Bankruptcy Court in Manhattan.
“I apologize on behalf of our entire team. I also called Boies Schiller Flexner LLP on Friday to thank th
em for bringing this matter to our attention and to apologize directly to them as well,” Dietderich wrote.
Boies Schiller Flexner is also involved in the case.
