Meta Platforms fell 4% to $567.58 as a 29-state child safety trial opens Tuesday in Oakland, with potential damages the company pegs as high as $1.4 trillion.
"The State AGs may call this a landmark case, but their limited claims are unsubstantiated, and their financial demands are vastly disproportionate," a Meta Platforms spokesperson said.
Pinterest dropped 4% to $23.15 and Snap fell 3% to $5.25 even though neither is a defendant in Tuesday's case, as investors repriced legal risk across the social media sector. Alphabet slipped 0.5% to $344.13, while the Communication Services Select Sector SPDR Fund declined 2% to $110.82.
A bellwether verdict could set terms for thousands of pending cases against social platforms, and Meta's own estimate of exposure — up to $1.4 trillion against a market value near $1.5 trillion — frames the stakes for the entire sector.
Trial Tests Meta's Design Defenses
The lawsuit, filed by 29 states in 2023, goes to trial in U.S. District Court for the Northern District of California before Judge Yvonne Gonzalez Rogers. California, Colorado, Kentucky and New Jersey are taking part, with testimony expected from Meta CEO Mark Zuckerberg and Instagram CEO Adam Mosseri. Plaintiffs allege the company built "psychologically manipulative platform features" — infinite scroll, autoplay and likes — designed to maximize time spent by young users, and that Meta knew its apps increased anxiety, depression and suicide risk. The states separately allege violations of the Children's Online Privacy Protection Act.
The case follows a string of adverse rulings. Earlier this month a New Mexico District Court ordered Meta to pay $567 million to address teen mental health plus $375 million in civil penalties. In March a jury found Meta and YouTube negligent in a suit alleging their products drove a user's dependency and self-harm, ordering $6 million in damages. Thousands of similar cases are pending in the U.S., and countries from Australia to Turkey have restricted children's use of these platforms.
Peers Reprice Sector Liability
The declines in Pinterest and Snap show the market treating the trial as an industry-wide liability question rather than a Meta-only problem. Snap is down 33% year to date, the steepest drop among the group, while Meta is down 10% and Pinterest down 7%. Alphabet's 0.5% slide and 11% year-to-date gain set it apart, despite YouTube being a co-defendant in the March verdict.
In a separate thread, BlackRock fell 2% to $1,154.47 after the Financial Times reported potential insurance gaps on a $14 billion data center project in El Paso, Texas. BlackRock holds an 80% interest and Meta owns the remaining 20% of the one-gigawatt campus. Insurance arranged through Marsh covers up to $218 million for certain construction delays and $645 million related to terrorism, with property protection of $427 million during construction rising to $450 million once operational.
Investors will watch whether Zuckerberg and Mosseri testify as expected, how the bellwether verdict lands, and whether additional states join or settle. A bellwether outcome can set terms for follow-on litigation, which is why peer stocks are moving even without direct exposure to Tuesday's case. Traders may also monitor for any revision to the El Paso insurance arrangements and further disclosures from Meta or BlackRock on the venture.
