U.S. cyber insurance returned to growth in 2025, with direct written premiums rising nearly 11% after two years of decline, according to Fitch Ratings. The increase was driven more by policy count than price, as policies in force climbed about 34% while aggregate pricing softened. That combination suggests the market is expanding through broader adoption and stronger competition, not through firmer underwriting terms.
For claims professionals, that matters because premium growth alone does not signal a healthier market. Fitch said incurred direct losses deteriorated by 5 percentage points, a sign that underwriting margins may narrow as more participants enter the space and rates ease. The report also flagged the danger of 'naive capacity,' where newer entrants compete aggressively without deep claims history or technical cyber expertise. That can create downstream problems in claim interpretation, reserving, and dispute resolution when losses become more severe or systemic.
The report points to several coverage and adjustment issues that should be familiar to claims teams. Fitch highlighted the importance of clear contract language around war exclusions, silent cyber, business interruption triggers, and contingent losses tied to vendor outages or infrastructure failures. Those are all areas where cyber claims can become fact-intensive and contentious, especially when insureds suffer operational disruption without a straightforward property damage component.
AI is another major factor in the story. Fitch said the release of Anthropic's Mythos model has intensified concerns across financial and cybersecurity circles because AI can speed up vulnerability discovery and lower barriers for attackers. While AI can also improve detection and incident response, Fitch expects vulnerabilities to outpace patches in the short to medium term. For adjusters, that points to a more active loss environment, more third-party exposure, and potentially more claims involving fast-moving attack chains that are harder to isolate and quantify.
The report also notes that cyber remains a niche line at about 1% of total direct written premiums, so its effect on overall multi-line insurer profitability is still limited. Even so, its claims complexity is outsized relative to its market share. That makes this an important trend story for adjusters, especially those watching how cyber losses intersect with business interruption, service providers, and policy wording disputes.
