Mass tort litigation is rapidly evolving, and 2026 is shaping up to be a landmark year in high-stakes lawsuits involving major Silicon Valley technology companies and ride-share platforms. While mass tort cases traditionally involve harmful physical products such as medications, medical devices, or chemicals, next year’s docket will also include groundbreaking claims involving digital platforms and consumer safety concerns. These lawsuits, many consolidated in California federal and state courts, are expected to attract intense legal and public scrutiny.
Uber Faces Thousands of Sexual Assault Claims
One of the most significant mass tort actions ahead involves Uber Technologies Inc. Plaintiffs largely women who used the Uber ride-sharing service allege that the company’s app facilitated a lack of safety protections that contributed to sexual assaults by drivers. The lawsuits claim Uber failed to implement adequate screening, reporting, and monitoring systems to protect riders from foreseeable harm. These cases have been centralized in multidistrict litigation (MDL) to streamline pretrial procedures and avoid inconsistent rulings across courts.
The Uber litigation stands out because it challenges longstanding legal norms: unlike classic product liability claims over defective goods, it focuses on allegations that a tech platform’s design and operational policies contributed to real-world physical harm. The upcoming bellwether trials test cases selected to represent broader claims will be closely watched by legal professionals evaluating whether existing tort law frameworks can extend to app-based services.
Social Media Platforms Face Addictive Design Lawsuits
At the same time, some of Silicon Valley’s largest social media companies are set to face mass tort trials in 2026 over allegations that addictive features in their apps cause widespread harm, particularly to children and teens.
Companies named in these major lawsuits include:
- Meta Platforms Inc. (parent of Facebook and Instagram)
- YouTube LLC (a division of Alphabet)
- Snap Inc. (Snapchat)
- TikTok Inc.
These cases claim that social media platforms intentionally engineered features that keep users engaged for extended periods often at the expense of mental health and wellbeing. Plaintiffs argue that algorithms, endless scrolling, “likes,” and other reward mechanisms contribute to anxiety, depression, body image issues, and even self-harm among young users.
More than 2,000 families and school districts have already filed coordinated lawsuits consolidated into a federal MDL in the U.S. District Court for the Northern District of California. Simultaneously, state court actions in California have been coordinated under separate proceedings. These complex cases are expected to generate bellwether trials beginning in early 2026, with some state-level trials scheduled as early as January and others following through spring and summer.
Why These Trials Matter
The 2026 mass tort trial schedule highlights two key legal developments. First, courts are increasingly willing to entertain claims that digital platforms not physical products can constitute the basis for mass tort liability. This shift reflects growing concerns over harm caused by technology, from physical violence facilitated through services like ride-hailing apps to psychological injury linked to social media usage.
Second, outcomes in these cases could establish legal precedents for future tech-related litigation. If juries find that platforms like TikTok or Instagram contributed to mental health harm, it could redefine corporate duties for how technology companies design, deploy, and monitor user experiences. These decisions may also influence pending and future cases involving youth addiction, algorithmic harm, and platform accountability.
Mass Tort Litigation Trends Going Into 2026
Mass tort cases have traditionally focused on defective products such as pharmaceuticals, medical devices, and toxic exposure. For example, bellwether trials in the talcum powder litigation against Johnson & Johnson and ongoing litigation over medical implant safety continue to shape the broader litigation landscape.
However, the inclusion of tech-driven claims in mass tort dockets marks a notable expansion in legal strategies. Courts are adapting procedures originally designed for physical injury cases to handle allegations of psychological harm and algorithm-driven addiction. This trend underscores plaintiffs’ attorneys’ efforts to hold large tech corporations accountable through coordinated litigation strategies.
Legal Community Preparing for Complex Trials
With cases involving millions of users and potentially billions of dollars at stake, law firms, courts, and corporate legal teams are investing significant resources into trial preparation. Expert witnesses, data engineers, behavioral scientists, and economists are expected to play major roles in upcoming trials, as juries and judges grapple with claims that link intangible digital experiences with tangible personal harm.
In the Uber MDL, expert testimony may focus on safety protocols, driver vetting procedures, and industry standards for ride-share platforms. In the social media lawsuits, experts in psychology, child development, and digital design may be called to testify about how features designed to maximize engagement affect user behavior and mental health outcomes.
Looking Ahead
As 2026 unfolds, Silicon Valley mass tort litigation will likely stand at the intersection of technology, public health, and tort law. These cases test not only the reach of current legal doctrines but also society’s expectations for corporate accountability in the digital age.
The trials will serve as early tests of how courts apply traditional harm principles to modern platforms and services. Their outcomes may influence litigation strategy across industries and set standards for how companies address user safety concerns in an increasingly digital world.
