Facebook, now Meta Platforms, has faced major lawsuits on nearly every front a tech company can be sued on: consumer privacy, biometric data, health-data tracking, antitrust, child safety, securities fraud, worker mental health, and AI copyright. The company has paid or committed to roughly $7.1 billion in privacy-related penalties and settlements alone, won the federal government’s attempt to force it to sell Instagram and WhatsApp (though that ruling is on appeal), and is now defending a wiretapping verdict that could cost billions more. Here is the state of play on each of the cases that matter.
Cambridge Analytica and the FTC’s $5 Billion Fine
The 2018 revelation that political consulting firm Cambridge Analytica had harvested data from roughly 87 million Facebook users triggered the largest wave of privacy litigation in the company’s history.1The Guardian. Facebook to Contact 87 Million Users Affected by Data Breach A personality-quiz app scraped not only quiz-takers’ profiles but also those of all their friends, which Facebook’s developer policies permitted at the time.
The Federal Trade Commission imposed a $5 billion penalty in July 2019, its largest corporate privacy fine ever. The FTC found that Facebook had violated a 2012 consent order by deceiving users about their control over personal information, sharing friends’ data with third-party developers even when those friends had chosen restrictive privacy settings, and using phone numbers collected for security purposes to target advertising.2Federal Trade Commission.

Users got their own recovery through a separate class action alleging Facebook improperly shared personal information with thousands of third parties without consent. A federal judge gave final approval to a $725 million settlement in October 2023. Payments began going out in September 2025 and averaged about $29 per claim, with the amount depending on how long someone had held an active Facebook account between May 2007 and December 2022.3CBS News.

The $650 Million Facial Recognition Settlement in Illinois
Facebook’s now-defunct “Tag Suggestions” feature scanned uploaded photos and identified faces automatically. In Illinois, that ran into the Biometric Information Privacy Act, which requires written consent before collecting facial scans or similar biometric data.
A 2015 class action alleged Facebook had collected and stored facial geometry data from Illinois users without notice or consent. The case settled for $650 million, which the presiding federal judge called a “landmark result.” Payments went to Illinois claimants over three distribution rounds, with the final checks issued in late 2023. Facebook shut down its facial recognition system entirely in late 2021 and deleted more than a billion face templates.
The Flo Health Data Wiretapping Verdict
In August 2025, a California federal jury found Meta liable for wiretapping under the California Invasion of Privacy Act. The case involved Meta’s advertising pixel, a tracking script embedded on third-party websites. Plaintiffs alleged the pixel secretly captured sensitive reproductive health information from users of the period-tracking app Flo and sent it back to Meta without consent.
The jury’s verdict established liability but did not fix damages. At an October 2025 damages hearing, the presiding judge indicated that the plaintiffs’ demand could push the total as high as $8 billion if the verdict survives appeal. Meta is expected to challenge the ruling. It is among the first cases to hold a tech company liable for ad-tracking tools that pull sensitive health data out of third-party apps.
The FTC Antitrust Case Over Instagram and WhatsApp
The federal government tried to break Meta up. In December 2020, the FTC sued the company for allegedly maintaining a monopoly in personal social networking by acquiring emerging rivals rather than competing with them.4Federal Trade Commission. Facebook Inc FTC v Meta Platforms Inc A coalition of 46 state attorneys general, the District of Columbia, and Guam joined the effort. The government targeted two deals in particular: the 2012 acquisition of Instagram for about $1 billion, and the 2014 purchase of WhatsApp for roughly $19 billion. The remedy sought was divestiture of both platforms.
The trial began on April 14, 2025. In November 2025, Judge James Boasberg of the U.S. District Court for the District of Columbia ruled that Meta had not broken the law. The FTC announced in January 2026 that it would appeal to the D.C. Circuit Court of Appeals, and the appeal was docketed on January 26, 2026, with initial briefing deadlines in February and March.5Federal Trade Commission.

Child Safety and Social Media Addiction Lawsuits
The fastest-growing legal front alleges Meta deliberately designed Instagram and Facebook to addict children and teenagers. In October 2023, a bipartisan group of 33 state attorneys general filed a federal lawsuit accusing Meta of deploying algorithmic feeds, push notifications, and autoplay features engineered to maximize screen time among young users. Nine additional state AGs filed parallel actions in their own states, bringing the total to 42.6Office of the New York State Attorney General. Attorney General James and Multistate Coalition Sue Meta for Harming Youth The suits allege Meta published misleading reports downplaying negative experiences while internal research showed the company understood the harm.
Thousands of individual and family lawsuits have been consolidated into a multidistrict litigation (MDL-3047) in the U.S. District Court for the Northern District of California. As of early 2026, the MDL contained more than 2,400 claims alleging that social media addiction caused depression, anxiety, eating disorders, and self-harm in children.
The first bellwether trial went to a jury in early 2026. The plaintiff, a 20-year-old identified as KGM, sued Meta and YouTube (owned by Google) for negligence; TikTok and Snap, originally named, settled before trial. Closing arguments were delivered in mid-March 2026, with jurors asked to decide whether each platform’s negligence was a “substantial factor” in the plaintiff’s harm.7PBS NewsHour. Lawyers Deliver Closing Arguments in Landmark Social Media Addiction Trial The outcome will heavily influence how thousands of similar claims are valued and whether they settle or proceed individually.
One reason these cases have gained traction: they largely sidestep Section 230 of the Communications Decency Act, which shields platforms from liability for user-posted content.8Office of the Law Revision Counsel. 47 USC 230 – Protection for Private Blocking and Screening of Offensive Material Plaintiffs frame their claims around product design rather than specific posts, arguing that addictive algorithmic features are a defective product. Courts have increasingly accepted that framing, and Meta’s Section 230 dismissal attempts have largely failed.
Shareholder Lawsuits Against Zuckerberg and the Board
Meta’s own shareholders sued too. A derivative lawsuit in the Delaware Court of Chancery alleged that Mark Zuckerberg and other directors and officers damaged the company through repeated failures to protect user data, ultimately saddling Meta with billions in fines and legal costs. Plaintiffs originally sought $8 billion.
In November 2025, Zuckerberg and current and former Meta directors agreed to a $190 million settlement, ending the trial before high-profile witnesses including Marc Andreessen, Sheryl Sandberg, Peter Thiel, and Reed Hastings could take the stand. Because it was a derivative case, the money was paid back to Meta itself rather than to individual shareholders. The California State Teachers’ Retirement System, co-lead plaintiff, called it the second-largest derivative settlement in Delaware history. Meta also agreed to governance reforms including enhanced whistleblower protections and stricter insider-trading policies.9CalSTRS.

A separate securities fraud class action is still active. Shareholders allege Meta misled investors about the severity of data misuse on its platforms. In March 2026, a federal judge allowed the proposed class action to proceed despite Meta’s efforts to pause discovery and dismiss the updated complaint.
Content Moderator PTSD Settlement
Content moderators employed through third-party contractors sued Meta over the psychological toll of the work, alleging they developed PTSD and other conditions from daily exposure to graphic images and videos of child abuse, murder, and suicide. The lawsuit claimed Facebook had drafted safety standards more than a decade earlier but never followed them.
Meta settled for $52 million, covering more than 11,000 contractors across four states. Each class member was guaranteed at least $1,000, with higher payments for those diagnosed with PTSD or related conditions. Meta also agreed to provide additional on-site counseling.
AI Training and Copyright Lawsuits
Meta’s newest legal front involves the material used to train its generative AI models. Authors, visual artists, and major media companies have sued, alleging Meta copied copyrighted works without permission. The central question is whether AI training qualifies as fair use.
In 2025, a federal judge in San Francisco ruled for Meta in one such case but warned that AI training “in many circumstances” would not qualify as fair use, particularly when it could flood the market with AI-generated content that undercuts the economic incentives for human creators. The fair-use defense is far from settled, and more copyright suits are expected to move through 2026. Separately, Ireland’s Data Protection Commission, Meta’s lead European regulator, has been reviewing whether training on public posts from Facebook and Instagram users in the EU complies with the General Data Protection Regulation.
Where Things Stand
Adding up the resolved privacy matters produces roughly $7.1 billion in payments and commitments: $5 billion to the FTC, $725 million in the user privacy class action, $650 million in the Illinois facial recognition settlement, $190 million in the shareholder derivative case, and $52 million to content moderators. The Flo health-data verdict could add billions more if the damages phase goes against Meta and the ruling survives appeal. The FTC’s push to break the company apart failed at trial but is alive in the D.C. Circuit. The child safety MDL, with more than 2,400 consolidated claims and a bellwether verdict pending, is the largest ongoing threat to how Meta actually runs its platforms.
