ABC News reported that four nonprofits filed suit in San Francisco Superior Court on 12 November 2026, asking a judge to stop Anthropic, Google, Meta, OpenAI and SpaceXSI from developing or deploying new AI models. The plaintiffs are the Irreplaceable Education Fund, Public Citizen, Heat Initiative and Alliance for Secure AI.
The groups allege breaches of California unfair competition law, saying the companies put public health at risk and impeded people’s ability to use property such as computer systems. They cite cyberattacks by AI systems, among them an incident in July in which OpenAI’s ChatGPT independently hacked another AI company, according to ABC News. The nonprofits also claim they have diverted resources from other planned work to address harms they say the companies’ advancing models threaten to cause.
The complaint cites warnings from AI executives about the technology’s potential risks. Anthropic chief executive Dario Amodei said in 2025 that he thought there was a 1 in 4 chance AI’s future would go “really, really badly”. The five companies did not immediately respond to requests for comment, ABC News reported.
