Antitrust Suit Accuses OpenAI, Anthropic, Google and SpaceXAI of Colluding to Slow AI Development

A new antitrust lawsuit filed in the U.S. District Court for the Northern District of California accuses OpenAI, Anthropic, Google and SpaceXAI of illegally agreeing to slow the pace of their AI development. Four named plaintiffs, each a paying subscriber to ChatGPT, Claude, Grok or Gemini, are bringing the suit on behalf of a proposed nationwide class of other paying customers, arguing the alleged coordination reduced the value people get for their subscriptions.

The suit centers on September 12, when Anthropic CEO Dario Amodei published an essay calling on leading AI labs to cooperate on decelerating development in the name of safety. OpenAI's Sam Altman, SpaceXAI's Elon Musk and Google DeepMind co-founder Demis Hassabis each publicly agreed the same day. The complaint also points to a July 2026 statement signed by senior employees at several AI labs acknowledging intense competitive pressure not to unilaterally slow down, which called on governments to back a coordinated global slowdown. Lead plaintiffs' attorney Nick Rowley argues AI safety protocols shouldn't be shaped by private agreements among the world's most powerful for-profit companies.

Altman has said OpenAI welcomes a federal framework setting consistent safety requirements but doesn't believe the industry needs to wait for an antitrust exemption to begin that work. President Trump has dismissed calls for AI regulation as a conspiracy and said he plans to form an AI task force and name an AI czar, without offering details. Sen. Josh Hawley has said he would never support giving the biggest AI companies an antitrust exemption to coordinate among themselves.

What supporters say:

  • Plaintiffs argue antitrust law bars competitors from deciding among themselves that competition is too dangerous, even if the shared goal is framed as safety.

  • A coordinated slowdown among the four largest AI labs could reduce the value subscribers get without those customers ever getting a say in the decision.

  • Allowing rivals to jointly set the pace of development sets a precedent that could be used to justify other forms of anticompetitive coordination down the line.

What critics say:

  • The companies say they aren't opposed to seeking government-backed safety rules and argue they don't need an antitrust exemption to act individually on safety.

  • Amodei's essay was a public call for industry cooperation on safety, not a secret pricing or output agreement, and each company's response was a separate public statement.

  • Treating open advocacy for safety coordination as an antitrust violation could discourage AI companies from ever discussing slowdown publicly, pushing similar conversations behind closed doors instead.
