An Overview of Active Mass Tort Litigation in 2026

Mass tort litigation continues to expand in scope and complexity in 2026, encompassing pharmaceuticals, medical devices, environmental exposures, consumer products, and emerging technology-related harms. Active mass tort lawsuits require individualized proof of injury and causation, making medical record review and clinical documentation central to litigation strategy.
For attorneys, claim professionals, and medical experts, understanding the current mass tort landscape, and the medical evidence required to support these claims, remains critical.

What Is Mass Tort Litigation?
Mass tort litigation involves multiple plaintiffs pursuing individual claims arising from harm allegedly caused by the same product, substance, or exposure. Unlike class actions, each plaintiff must demonstrate personal injury, medical causation, and damages. Many mass tort cases are consolidated through Multidistrict Litigation (MDL) to streamline discovery and pretrial proceedings while preserving individualized claims.
