Nonprofits Sue OpenAI, Anthropic, Google and Meta to Halt Frontier AI Buildout
Nonprofits sued OpenAI, Anthropic, Google, and Meta in San Francisco, citing California's Unfair Competition Law to halt development of advanced AI models like ChatGPT, Gemini, and Claude. The plaintiffs argue the companies' practices pose public nuisances and risks. Anthropic's IPO, valued at up to $1.4 trillion, may be impacted if an injunction is granted. Gartner projects global AI spending to rise from $2.746 trillion in 2026 to $4.050 trillion in 2027.
