Key Takeaways: Meta enters federal court Tuesday facing a potential $1.4 trillion penalty — nearly its entire market value — in the largest US consumer protection case ever.

Meta faces a potential $1.4 trillion penalty as 29 state attorneys general open a federal trial Tuesday, accusing the company of designing Facebook and Instagram to addict children and mislead parents about safety.
"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," Rob Bonta, California's attorney general, said in a statement ahead of the proceedings.
The trial before US District Judge Yvonne Gonzalez Rogers in Oakland centers on alleged violations of state consumer protection laws and the Children's Online Privacy Protection Act, with fines of up to $20,000 per violation per young user. Meta estimates its theoretical maximum exposure at $1.4 trillion, an amount approaching its entire market capitalization and unprecedented in legal history. State lawyers cited $200 billion as a more likely figure, while California placed potential penalties around $193 billion.
The stakes extend beyond fines. The states are seeking permanent injunctive relief requiring Meta to delete personal data of children under 13 and remove "certain addictive design features," including infinite scroll, autoplay, beauty filters and engagement-optimized algorithms. A loss could force fundamental changes to the algorithms that drive Meta's ad business, which generates 98 percent of revenue and funds a $145 billion AI spending plan this year.
A precedent in New Mexico
The California case follows a landmark New Mexico ruling that ordered Meta to pay $942 million across two phases — a $375 million jury verdict in March for violating the state's unfair practices act, plus a $567 million abatement fund ordered in August. New Mexico Judge Bryan Biedscheid also imposed five years of reforms, including age verification, overnight limits on push notifications and mandatory time-use limits for users under 18.
"California matters more than any other jurisdiction in the U.S.," said Julia Powles, executive director of the UCLA Institute for Technology, Law and Policy. "It's where they are subject to the greatest legal reach, and it's a jurisdiction watched around the world."
New Mexico Attorney General Raúl Torrez, who secured the victory, told CNBC the consequences could be "astronomical" for a company that gets 98 percent of its revenue from online advertising. "You could wake up with a headline judgment that is, as I've said, astronomical," he said. Torrez is now drafting two bills with state lawmakers to strengthen consumer protections and child safety online, building on the court win.
A wave of litigation
The states' focus on app design features and alleged misrepresentations about safety allows them to bypass Section 230 of the Communications Decency Act, which has generally shielded tech companies from liability for third-party content. Meta has denied the allegations, arguing the states offer "no proof anyone in their states was misled" and that the suit targets "industry-wide challenges like age verification."
Meta and Google's YouTube lost a separate case in March, when a Los Angeles jury found the companies negligent and ordered them to pay $6 million to a young user who said the platforms' algorithms worsened her mental health. The company also faces more than 3,000 personal injury suits and roughly 1,300 school district lawsuits across the US, though Meta, YouTube, TikTok and Snap settled the first consolidated school district case in May.
Meta's stock is down 11 percent this year, with most analyst concern focused on its AI infrastructure spending rather than litigation risk. Torrez argues Wall Street is underestimating the potential significance of a California loss. "The analysts aren't pricing this correctly right now," he said. "That California judgment by itself could be gargantuan enough that it changes the ability of this company to do what it needs to finance into the future."
Mark Zuckerberg and Instagram head Adam Mosseri are expected to testify during the trial, which is being argued by lawyers representing California, Colorado, Kentucky and New Jersey. A ruling against Meta could set a template for the remaining state cases and reshape how social media platforms design products for younger audiences.
