Meta’s Biggest Legal Test Begins: Trial Over Child Social Media Addiction Opens in Oakland
Opening arguments began Tuesday, August 18, in federal court in Oakland, California, in what legal experts are calling the most significant trial yet over whether Meta deliberately designed Facebook and Instagram to be addictive to children — a case that could result in penalties as high as $1.4 trillion and force fundamental changes to how the platforms operate.
What the States Are Arguing
The trial is being argued on behalf of a bipartisan coalition of 29 state attorneys general, though the case itself is being tried specifically by lawyers representing California, Colorado, Kentucky, and New Jersey, according to NBC News. California Deputy Attorney General Megan O’Neill laid out the states’ central theory in her opening statement, according to NPR: “Meta’s business model can be summed up in four simple words: ‘hook’ the users, ‘hold’ them for as long as they can, ‘harvest’ their data, and then ‘hide’ the truth from the public when making public statements.”
The states allege Meta violated the federal Children’s Online Privacy Protection Act, or COPPA, by collecting data from children under 13 without parental consent, and separately allege the company designed specific features — including the “like” button, infinite scroll, and recommendation algorithms — specifically to maximize young users’ time on the platforms at the expense of their mental health, according to NPR. New Jersey Attorney General Jennifer Davenport told NPR ahead of the trial: “They’re putting the profits … over the health of a generation of young people.”
California Attorney General Rob Bonta framed the case in blunt terms in a statement issued before trial, according to CNN: “Meta designed a dangerous product for young users, knew it to be dangerous, and then lied to children, families, and the community about how dangerous it was.”
Meta’s Defense
Meta has firmly denied the allegations. Company attorney Paul Schmidt told the court’s advisory jurors that Meta “strongly disagrees” with the claims, according to Axios, and sought to contextualize what he called “loose language” in internal communications the states plan to present as evidence. Schmidt argued that measuring user engagement is a legitimate business goal, that Meta has built tools to help people manage their time on its platforms, and he questioned whether there’s sufficient scientific evidence that social media addiction is even possible as a diagnosable condition, according to Axios.
In a statement provided to reporters, a Meta spokesperson was more pointed: “The State AGs may call this a landmark case, but their limited claims are unsubstantiated and their financial demands are vastly disproportionate. The AGs offer no proof anyone in their states was misled, claim benign features like having an additional Instagram account somehow harmed their residents, and attempt to penalize Meta for industry-wide challenges like age verification,” according to reporting from MyFox28 Columbus. Reuters separately reported that Schmidt told jurors Meta and CEO Mark Zuckerberg “share a desire to improve their services, not make them dangerous,” adding: “They don’t believe they’re going to do well if people don’t like their service.”
Fox Business noted that Meta plans to specifically challenge whether “social media addiction” constitutes a recognized psychiatric diagnosis — a scientific and definitional dispute likely to become a significant point of contention throughout the trial.
How the Trial Will Work
The case will be heard by U.S. District Judge Yvonne Gonzalez Rogers, who has presided over several high-profile tech cases recently, including Elon Musk’s lawsuit against OpenAI, according to Oaklandside. An eight-person advisory jury has been convened, but per NBC News, the jury’s verdict will be advisory only — Gonzalez Rogers herself will determine Meta’s actual liability and, if she finds the company liable, decide what civil penalties or platform changes to impose.
The trial is expected to run four to eight weeks, with estimates varying slightly by outlet, and both Meta CEO Mark Zuckerberg and Instagram head Adam Mosseri are expected to testify, according to CNN and NBC News.
The Stakes: How Big Could the Penalty Be?
The financial numbers at stake have themselves become a point of dispute. Multiple outlets, including the Wall Street Journal, reported ahead of trial that the four states were seeking $1.4 trillion in damages — a figure Reuters noted is close to Meta’s entire market value on the Nasdaq. Following opening statements, however, Bonta clarified that the states are not actually seeking that specific amount, according to MyFox28 Columbus, with a more recent estimate discussed at a pretrial hearing putting potential penalties closer to $200 billion — roughly three years of Meta’s after-tax profit, according to US News/Reuters.
Why This Case Is Being Compared to Big Tobacco
Legal observers have drawn direct comparisons between this trial and the landmark 1990s litigation against tobacco companies that forced major settlements and reshaped public understanding of cigarettes’ health risks. NPR reported that some legal experts see this moment similarly — as a potential turning point where sustained state-level litigation forces systemic change at a major industry, rather than simply resulting in a one-time monetary penalty.
This Isn’t Meta’s Only Legal Fight Over Youth Safety
The Oakland trial is part of a much broader wave of litigation the company is currently facing. According to NBC News, a Los Angeles jury ordered Meta and Google to pay $6 million in March to a 20-year-old woman who said she became addicted to Instagram and YouTube as a child. Earlier this month, a New Mexico judge ordered Meta to pay $567 million into a mental health fund for teenagers after that state’s attorney general argued the company’s platforms constituted a public nuisance. Separately, Tennessee is in the midst of its own trial against Meta over similar allegations, and Massachusetts’ highest court heard oral arguments in December 2025 in a related state lawsuit that raises First Amendment questions about how far liability can extend to a platform’s design choices versus its published content.
CNN noted that Meta also faces thousands of additional lawsuits over similar claims, alongside other major platforms including Snap and TikTok, making the Oakland case a closely watched bellwether for how this broader category of litigation may ultimately be resolved.
FAQ
Which states are bringing this case to trial? California, Colorado, Kentucky, and New Jersey are trying the case in court, representing a broader coalition of 29 states that joined the underlying lawsuit.
What is Meta accused of doing? Deliberately designing Facebook and Instagram features — including infinite scroll, the “like” button, and recommendation algorithms — to be addictive to children, misleading the public about the platforms’ risks, and collecting data from children under 13 without parental consent in violation of federal law.
How has Meta responded? The company denies the allegations, arguing its features serve legitimate business purposes, that it has built tools to help users manage their time on the platforms, and that the scientific basis for “social media addiction” as a diagnosis is disputed.
How much money are the states seeking? Initial reporting cited a potential figure as high as $1.4 trillion, though Bonta clarified after opening statements that the states are not seeking that amount; a more recent estimate put potential penalties closer to $200 billion.
Who decides the outcome of the trial? An eight-person advisory jury will issue a non-binding verdict, but U.S. District Judge Yvonne Gonzalez Rogers will make the final determination on Meta’s liability and any resulting penalties.
Will Mark Zuckerberg testify? Yes, along with Instagram head Adam Mosseri, both are expected to take the stand during the trial.
Conclusion
This trial represents the most significant legal test yet of the years-long effort by state attorneys general to hold Meta accountable for its platforms’ effects on young users, arriving after a string of smaller but consequential wins for plaintiffs in related cases in New Mexico and Los Angeles. With Judge Gonzalez Rogers ultimately holding sole authority over any final penalty or required platform changes, and both Zuckerberg and Mosseri expected to testify over the coming weeks, the trial’s outcome could shape not just Meta’s own products but the broader legal landscape facing every major social media company currently navigating similar litigation.
