Sun Feb 01 2026 09:00:17 GMT+0200 (Eastern European Standard Time)

A landmark trial in California is set to begin, challenging major social media platforms on their role in fostering addiction and mental health issues among users, with top executives, including Meta's Mark Zuckerberg, expected to testify.

The California court will hear a case brought by a 19-year-old woman claiming that social media algorithms have led her to addiction and mental health problems. Major tech companies including Meta, TikTok, and Google are defendants in what could reshape legal accountability for social media design practices. As the trial unfolds, executives will face scrutiny over their platforms' impact on youth and the alleged harmful effects of their services.

Tech Giants Face Historic Trial: A Challenge on Social Media Addiction

A landmark social media addiction trial in which top tech executives are expected to testify begins on Tuesday in California. The plaintiff, a 19-year-old woman identified by the initials KGM, alleges the design of the platforms' algorithms left her addicted to social media and negatively affected her mental health.

The defendants include Meta - which owns Instagram and Facebook - TikTok's owner ByteDance, and Google, the parent of YouTube. Snapchat recently settled with the plaintiff before the trial.

This closely watched case at Los Angeles Superior Court represents the first of a wave of lawsuits challenging the legal protections that tech firms have traditionally invoked to evade liability in the US. The case focuses on the design features that many believe contribute to addictive behaviors.

‘Dangerous and Addictive Algorithms’

While the named social media companies contend that the plaintiff's claims lack sufficient evidence to prove direct causation with alleged harms such as depression and eating disorders, KGM's attorney contends that the litigation aims to hold these companies accountable for leading youths into addiction through 'dangerous and addictive algorithms.'

Experts warn that the outcome of this trial could dramatically alter the landscape of legality for technology firms that have claimed immunity under Section 230 of the Communications Decency Act, which has historically protected them from legal action arising from user-generated content.

However, as KGM's attorney correctly points out, fundamental design choices—including algorithm construction—pertain to the companies’ accountability under law.

With significant evidence, including internal company documents, expected to be presented during the trial, the case is anticipated to shine a light on corporate accountability. Meta’s CEO, Mark Zuckerberg, is slated to testify—his first public account on this issue amid growing scrutiny of social media's impact on youth mental health.

Changing Perceptions and Legal Realities

The trial emerges in a time of escalating global concern regarding social media's influence on mental health, particularly among adolescents. Recent lawsuits against tech giants highlight societal demands for increased accountability and scrutiny.

As the case progresses, experts caution the inherent challenge for plaintiffs to establish a direct link between social media usage and physical or psychological harm. Yet this trial may serve as a tipping point, shifting how the legal system interacts with technology firms and reassessing their long-held legal protections.

The trial not only engages critical legal questions but opens the door for broader implications regarding youth safety in the digital landscape. This pivotal moment could redefine the relationship between social media companies and their responsibility to younger audiences grappling with addiction and mental health issues.
