As the calendar turns to 2026, the mass tort landscape is shifting in ways that will define the next decade of litigation.
For plaintiff attorneys and trial teams, the question isn’t just what has happened — it’s which mass torts will dominate 2026 litigation, and which mass tort cases will demand fast, strategic action.
At Kelley | Uustal, our law firm is preparing for the next wave of tort cases by monitoring scientific evidence, filing trends, federal court developments, and early class action lawsuit activity. We’re not waiting to react; we are actively positioning our clients and partners for what’s coming.
The New Frontiers of Mass Tort Litigation
Traditional product liability litigation—a single device, a single failure—no longer defines the field. What’s emerging now are high-profile, cross-industry harms, complex exposure networks, and chemical use outpacing federal regulation.
The real question for plaintiffs lawyers heading into 2026 is simple:
Where did the danger outrun the warning?

Case to Watch #1 – GLP-1 Weight-Loss Drugs & Device Lawsuits
GLP-1 agonists such as Ozempic, Wegovy, and Mounjaro have surged across social media, pop culture, and mass-market wellness trends. Now, plaintiffs allege severe gastrointestinal injuries, vision complications, and harmful long-term side effects, triggering one of the most closely watched new mass tort lawsuits 2026 is likely to see.
Expect filings in both state court and district court, with potential consolidation into a high-volume MDL. Early motions to dismiss will determine how fast these claims scale.
What it means for law firms:
- Prepare streamlined intake for drug-injury claims
- Start building causation files supported by medical timelines
- Identify early users with atypical or severe harm
This is a mass tort claim where early movement matters.
Case to Watch #2 – PFAS & “Forever Chemicals” in Consumer Products
PFAS litigation has matured from municipal contamination cases into a massive wave of product liability litigation involving cosmetics, hair products, treated fabrics, and food packaging. Plaintiffs are filing injury, exposure, and property damage claims tied to the chemicals’ persistence.
In 2026, PFAS represents one of the largest plaintiff mass tort opportunities — with ongoing federal court action, bellwether trials, and the possibility of a future global settlement.
Strategic steps for attorneys:
- Build exposure documentation before defendants restrict data
- Leverage environmental records and scientific evidence
- Create criteria for selecting strong plaintiffs
PFAS will remain one of the country’s most high profile and long-term mass tort battles.
Case to Watch #3 – Product Liability & Device Failure in High-Tech Health Care
AI-enabled medical tools, implantable micro-devices, and connected health tech are becoming the next frontier of product liability and mass tort litigation trends. When these devices fail, malfunction, or compromise patient data, the harm is often invisible until catastrophic.
2026 could see accelerated filings as regulators catch up and plaintiffs allege untested long-term consequences.
Why this matters:
- Device-failure cases often hinge on digital logs and software data
- Early evidence preservation is critical
- These cases may generate the next major MDLs in district court
For plaintiffs lawyers, the opportunity lies in mastering failure-mode analysis and building alliances with engineering and cybersecurity experts.
What Separates the Firms That Win from the Firms That Wait
Firms waiting on the sidelines for bellwether trials often find themselves buried in crowded dockets and paying more for intake.
Firms that move early secure:
- Leadership opportunities
- Strong plaintiffs before saturation
- A discovery advantage rooted in early evidence
At Kelley | Uustal, we apply the same approach that recently helped us secure a $28.75 million settlement for a client paralyzed after a van cut him off. This was a case with no physical impact, won by uncovering hidden corporate negligence and a pattern of reckless conduct.
Mass torts demand that same type of investigation:
Not just finding the injury, but finding the decision, design, or exposure no one saw coming.
Lessons for Trial Lawyers – How Plaintiff Law Firms Should Prepare for Mass Tort Cases in 2026
- Qualify plaintiffs early.
Use screening protocols aligned with each emerging tort — drug use dates, exposure levels, device versions, documented injuries. - Preserve scientific evidence immediately.
In chemical, device, or product cases, delay kills claims. Secure environmental reports, firmware logs, maintenance records, and medical files. - Build the “unwarned risk” narrative.
Defense teams focus on what was disclosed. Your story must focus on what was not — the risk hidden, the defect ignored, the exposure untested. - Prepare for scale without sacrificing individual case strength.
The best mass torts combine volume with airtight causation files. - Form strategic alliances.
2026 will reward collaboration — from local counsel to national trial partners. KU is ready to support firms in leadership roles, referral arrangements, or high-complexity litigation.
Final Word – The Legal Field Isn’t Slowing Down
2026 won’t be defined by past verdicts. It will be defined by the emerging mass torts 2026 is already signaling: drugs, chemicals, devices, and failures where warning systems lag behind human harm.
For plaintiffs attorneys, the question isn’t if the next wave is coming.
It’s which wave will define your practice, and whether you’re positioned to lead it.
At Kelley | Uustal, we’re already preparing. We understand that these cases are not passive market forecasts. They’re active battlegrounds.
