The litigation environment shifted significantly in 2025, and that trend is expected to continue this year. Regulatory shifts, scientific advancements, and emerging technologies are reshaping the types of claims consumers bring, and the risks companies face. For plaintiffs’ attorneys, 2026 is poised to be a pivotal year marked by new opportunities, expanding case categories, and increasing public awareness of harms that were once overlooked.
Here are the four major areas of litigation expected to trend sharply upward in 2026.
1. “Forever Chemical” Litigation
PFAS (per- and polyfluoroalkyl substances) remain one of the most explosive areas of mass tort and environmental litigation. Known as “forever chemicals” for their persistence in water, soil, and the human body, PFAS are now linked to a broadening list of health concerns, including cancer, liver damage, immune issues, and reproductive harm. Manufacturers, municipalities, and water systems are identifying contamination at unprecedented rates, and stronger evidence makes claims easier to pursue and harder for defendants to dismiss.
For plaintiff firms already in the toxic exposure space, PFAS remains a top priority. For others, 2026 may be the year to expand into environmental harm and consumer product contamination claims.
2. Product Liability Sees a Modern Renaissance
Product liability is entering a new era, one driven by increasingly complex supply chains, global manufacturing, and rapid product innovation. A handful of product categories are expected to lead the way in liability claims:
- Battery-related injuries: As electric vehicles, e-bikes, and lithium battery–powered devices proliferate, so do fires, explosions, and severe burn injuries.
- Cosmetics & personal care products: Elevated concern over chemical exposure, especially PFAS, talc, and heavy metals, is fueling new product claims.
- Children’s products and safety recalls: Toy defects, choking hazards, and unsafe baby products remain high-profile litigation categories.
Design & software defects: Products are more digital than ever, creating new pathways for failure and new defendant classes.
2026 will see more consumer awareness, more recalls, and more scrutiny of both domestic and foreign manufacturers.
3. Social Media Harm Lawsuits Gain National Momentum
Claims alleging mental health harms, addictive design, and youth-targeted algorithmic features are multiplying, and 2026 will be a defining year in this category. Studies continue linking excessive social media use to depression, anxiety, self-harm, and sleep disruption in minors. This newfound evidence, coupled with new youth social media safety laws, is creating private rights of action and expanding liability.
Social media litigation is no longer hypothetical, it’s structurally similar to past waves of mass torts involving tobacco, opioids, and defective products. Expect large-scale consolidation and nationwide filings through 2026.
4. AI Misuse Becomes a New Frontier for Plaintiffs Attorneys
Artificial intelligence is now embedded in business operations, healthcare, financial decisions, vehicles, and everyday apps. With that integration comes liability, and courts are only beginning to see the consequences. Top categories of AI-related claims will be: biased or discriminatory outputs, incorrect AI guidance, privacy breaches, and liability for autonomous systems.
As regulators scramble to catch up, plaintiffs’ attorneys will play a pivotal role in defining the boundaries of AI responsibility.
The Bottom Line
2026 is shaping up to be a pivotal year for plaintiff-side litigation. From chemical exposure and product defects to social media and AI harms, the opportunities and responsibilities for plaintiff attorneys are expanding rapidly.
Firms that stay ahead of these trends, invest in expertise, and prepare for complex, multidisciplinary claims will be best positioned to lead the next wave of consumer protection and personal injury litigation.
