AI Insurance Coverage Gaps: Delaware Duty-to-Defend Ruling and May 2026 Commercial Policy Exclusions

Corporate risk and legal departments face a rapidly shrinking safety net as both courts and major commercial insurers move to exclude artificial intelligence risks from standard corporate insurance policies. A landmark judicial ruling in Delaware combined with a coordinated wave of regulatory filings by major insurers in May 2026 signals a definitive end to "silent AI" coverage under standard Commercial General Liability (CGL) and Directors and Officers (D&O) policies.

The Delaware Precedent on Duty to Defend (February 2026)

On February 27, 2026, the Delaware Superior Court ruled that nearly two dozen of Meta’s liability insurers have no duty to defend the company in thousands of consolidated lawsuits alleging social media harms. The court rejected Meta's arguments that standard general liability policies should cover these claims, finding that the alleged algorithmic harms fell outside the scope of traditional "bodily injury" or "personal injury" definitions in standard policies. This ruling established a critical precedent: enterprises cannot assume that traditional CGL or D&O policies will cover the costs of defending against lawsuits arising from AI-driven algorithms or automated systems.

Insurers File Specific AI Exclusions (May 2026)

Following the judicial momentum, major commercial insurance carriers have moved from litigating existing policies to proactively rewriting future ones. In May 2026, leading global insurers—including AIG, W.R. Berkley, and Great American—began filing specific, explicit exclusions for AI liability in their corporate policy offerings.

These filings represent a major structural shift in the commercial insurance market:

• Explicit Exclusions: Rather than relying on interpretations of traditional exclusions, carriers are introducing dedicated "Artificial Intelligence Exclusions" that bar coverage for any claims involving algorithmic bias, model hallucinations, flawed automated decision-making, or training data copyright disputes.
• The Death of "Silent AI" Risk: "Silent AI" risk—where an insurer might inadvertently cover AI-related damages because the policy does not explicitly mention AI—is being systematically eliminated. Underwriters are forcing enterprises to purchase highly specialized, standalone AI insurance policies, which are currently expensive, limited in capacity, and subject to intensive technical underwriting.
• Implications for Enterprise Deployers: Legal and risk management teams must audit their existing portfolios immediately. Standard D&O, CGL, and Professional Liability (E&O) policies are unlikely to shield the company from AI-related liabilities. Any enterprise deploying predictive, generative, or agentic AI must expect explicit AI exclusions in their next renewal cycle.
