Arkansas appeals court orders insurers, including AIG units, to defend Walmart in 2,400+ opioid lawsuits

An Arkansas Court of Appeals ruled on October 7, 2026 that more than 30 insurers, among them two AIG units, must cover Walmart's defense costs in over 2,400 opioid-related lawsuits. The court applied the gravamen test and found the complaints allege negligence, triggering the duty to defend under standard CGL policies. The decision addresses only defense obligations, not settlement liabilities.

The ruling obligates insurers to pay defense expenses for thousands of opioid cases, increasing their exposure and potentially affecting insurance pricing. Walmart’s litigation costs may rise, while insurers face higher reserves for defense obligations.
