Tech stocks slip as Meta faces high-stakes trial and chip names slide

At a glance

  • Nasdaq declined more than 1% and the Philadelphia Semiconductor Index fell over 5% in early trading.
  • A coalition of 29 state attorneys general has sued Meta, alleging it designed features to maximize time children spend on its platforms; Meta says exposure could reach $1.4 trillion.
  • OpenAI launched ChatGPT for Teens with safety features aimed at younger users.
  • Anthropic reported preliminary quarterly revenue of $11.5 billion (up from $787 million a year ago) and is reportedly targeting a ~$2 trillion valuation ahead of an IPO.
  • Nvidia agreed to back an SB Energy and OpenAI data center project in Ohio worth $105 billion, supporting 4.25 GW of initial capacity using Nvidia chips.

Market snapshot and legal pressure on Meta

Tech stocks opened lower Tuesday, led by a more than 1% drop in the Nasdaq and a sharper slide in semiconductor namesthe Philadelphia Semiconductor Index fell more than 5% in early trading. Investors appeared cautious as a high-profile legal test of social media practices begins in California.

A trial in Oakland, Calif., brought by a coalition of 29 state attorneys general against Meta Platforms kicked off today. The states allege Meta deliberately engineered its services to keep children online for longer periods and that those product design choices caused psychological harm. Meta has warned the case could expose it to as much as $1.4 trillion in damages; the state attorneys general dispute that figure.

AI developments and chip-related deals

AI and chip-related headlines also shaped market sentiment. OpenAI announced a product tailored to younger usersChatGPT for Teensdesigned with built-in protections to limit exposure to harmful content, prompt regular breaks, and reduce the risk of teens forming relationships with the AI. The rollout is part of a broader industry effort to demonstrate safer AI deployments for vulnerable user groups.

Rival AI lab Anthropic is drawing attention for its rapid revenue growth as it ramps toward an IPO. Bloomberg reports preliminary quarterly revenue jumped about 14-fold year-over-year to $11.5 billion from $787 million. The Financial Times says investors are targeting a roughly $2 trillion valuation as Anthropic prepares a possible public offering in September or October.

Nvidia remains central to the AI infrastructure story. The company said it has entered an agreement to support an SB Energy and OpenAI data center project in Ohio valued at $105 billion. Nvidias contribution will underwrite an initial 4.25 gigawatts of computing capacity built exclusively using Nvidia chips, with an option to participate in an additional 3.75 gigawatts later. The scale of the deal underscores the continued link between large AI deployments and demand for advanced semiconductors, a link that helps explain the sensitivity of chip stocks to headline news.

What to watch next Traders will be monitoring developments in the Meta trial for any broader regulatory or liability implications for social media platforms. Separately, investors will be watching AI revenue trajectories, IPO timing for major labs such as Anthropic, and large-scale infrastructure commitments that tie chip vendors like Nvidia to long-term demand.

For now, risk appetite in technology appears muted: Meta faces legal uncertainty, chip names are under pressure, and the sector is digesting both regulatory and capital-intensity headlines that could influence earnings and investment plans going forward.
