Quick Summary
A landmark trial pitting Meta Platforms against four U.S. states opened Tuesday in a federal courtroom in Oakland, California, with attorneys general alleging the company deliberately designed Facebook and Instagram to be addictive to children and misled the public about the resulting harm. The case, brought by California, Colorado, Kentucky, and New Jersey, carries potential penalties legal analysts have estimated as high as $1.4 trillion, roughly equivalent to Meta’s entire market value on the Nasdaq. The trial is expected to last several weeks and is being watched as a bellwether for a much larger wave of similar lawsuits filed by more than 40 state attorneys general nationwide, all consolidated into a single federal multidistrict litigation process.

What Happened
Opening statements began Tuesday before District Judge Yvonne Gonzalez Rogers, who previously oversaw Elon Musk’s lawsuit against OpenAI and has developed a reputation for handling complex Silicon Valley disputes. An eight-person jury is seated in an advisory capacity only, meaning Judge Rogers will ultimately decide the case herself rather than the jury reaching a binding verdict.
Attorneys for the states argued that Meta knowingly built features like the “like” button, infinite scroll, and recommendation algorithms specifically to encourage compulsive use among young people, while publicly downplaying the risks those features posed. One attorney representing the states told the court that Meta needed young users and needed to reassure worried parents that their kids were safe, even as the company understood the platforms’ dangers internally. The states are also pursuing claims that Meta violated the federal Children’s Online Privacy Protection Act by collecting personal data from users under 13 without parental consent.
A Meta spokesperson pushed back sharply following the opening arguments, calling the states’ claims unsubstantiated and their financial demands vastly disproportionate. The spokesperson argued the states have offered no proof that anyone in their jurisdictions was actually misled, and accused them of chasing an outlandish payout rather than sticking to the facts or the law. Following opening statements, the states called their first witness, Arturo Bejar, a former Facebook safety engineer and Instagram consultant, who began testifying about internal safety concerns he says he raised with company leadership.

Background
The federal case is one piece of a much larger legal reckoning facing Meta. It functions as a bellwether trial within a consolidated multidistrict litigation process based in the Northern District of California, one designed to establish legal precedent and consistency across thousands of similar claims rather than litigating each individually. More than 40 state attorneys general have filed related claims against the company as part of this broader coordinated effort, though the specific trial that began Tuesday involves only the four states pursuing this particular federal case.
Meta has already lost related cases in state courts this year, giving a preview of how costly this broader wave of litigation could ultimately become. In March, a Los Angeles jury found Meta and Google liable for the depression and anxiety experienced by a young woman, identified in court filings only as K.G.M., who had started using YouTube at age six, Musical.ly (later TikTok) at ten, and Snapchat at eleven, developing what the family’s lawsuit described as compulsive social media use throughout her childhood. The jury awarded her and her mother $3 million in damages, with Meta found responsible for roughly 70% of that amount.
Meta has already lost related cases in state courts this year. In March, a Los Angeles jury found Meta and Google liable for the depression and anxiety experienced by a young woman who had used social media compulsively since childhood, awarding her family $3 million in damages, with Meta responsible for roughly 70% of that amount. Separately, a New Mexico judge ordered Meta to pay more than $567 million and implement new safety measures after a jury found the company failed to protect young users from child sexual exploitation on its platforms.
Meta itself acknowledged the mounting legal exposure in a January filing with the U.S. Securities and Exchange Commission, stating that the lawsuits it faces, including youth addiction claims, could result in substantial monetary damages or fines.
Legal experts have drawn direct comparisons between this litigation wave and the tobacco industry lawsuits of the 1990s, which eventually forced major settlements and reshaped both corporate behavior and public understanding of cigarette risks. Whether the current wave of social media litigation follows a similar trajectory is one of the central questions hanging over the industry as this trial unfolds.
Why It Matters
The scale of the potential penalty, an estimate reaching into the trillions of dollars, reflects just how consequential this case could be, not only for Meta’s finances but for the fundamental design of some of the most widely used technology products in the world. Beyond monetary damages, the states are explicitly asking the court to order structural changes to Meta’s platforms, potentially including the removal of features like visible “like” counts and the end of infinite scroll, changes that would directly reshape the daily experience of billions of users if ordered.
Industry analysts have noted that Meta enters this trial in a difficult position, facing what one analyst described as an onslaught of lawsuits and scrutiny with no clear unifying strategy for addressing the underlying concerns driving them. Because the case serves as a bellwether within a much larger consolidated litigation process, the outcome is likely to significantly influence how the dozens of other pending state lawsuits against Meta proceed, making Judge Rogers’ eventual ruling consequential well beyond the four states directly involved in this specific trial.

Statistics & Context
- Potential penalty estimated by legal analysts: up to $1.4 trillion, roughly Meta’s entire Nasdaq market value
- States directly bringing this specific federal trial: 4 (California, Colorado, Kentucky, New Jersey)
- Total state attorneys general involved in the broader consolidated litigation: more than 40
- Jury size, serving in an advisory-only role: 8 members
- Expected trial duration: several weeks
- New Mexico judgment against Meta earlier this year for child exploitation failures: more than $567 million
- Damages awarded in the March Los Angeles case against Meta and Google: $6 million
What’s Next
The trial is expected to continue for several weeks, with Meta’s top executives, including CEO Mark Zuckerberg and Instagram head Adam Mosseri, likely to take the stand as proceedings continue. Because Judge Rogers alone will decide the case rather than the advisory jury, her eventual ruling is expected to carry significant weight as a legal precedent for the dozens of other state lawsuits still pending against Meta within the broader multidistrict litigation. Whether the case ultimately produces a settlement, similar to the tobacco litigation of the 1990s some legal experts have referenced, or proceeds to a full judicial ruling on damages and required platform changes, remains to be seen.
