What happened
A lawsuit filed in the U.S. District Court for the Northern District of California claims that Anthropic, OpenAI, SpaceXAI, and Google illegally agreed to slow down their AI development. The plaintiffs argue that this coordination violates antitrust laws and reduces consumer value for paid AI subscriptions. The alleged agreement began with Anthropic CEO Dario Amodei's essay on September 12, 2026, urging industry-wide cooperation on decelerating advancements in favor of enhanced safety measures, to which other CEOs publicly responded in agreement.
The lawsuit was filed by four named plaintiffs who pay for subscriptions to ChatGPT, Claude, Grok, or Gemini, representing a proposed nationwide class of other paid subscribers to those services.
The plaintiffs argue that the coordination among the AI companies began with a statement from July 2026 signed by high‑ranking employees, acknowledging the "intense competitive pressure not to unilaterally slow" development.
The lawsuit also points to the September 12, 2026, public responses by Anthropic, OpenAI, SpaceXAI, and Google to Amodei's proposals, indicating an agreement to slow down AI development.
The plaintiffs do not object to individual companies deciding to slow their progress for safety but argue that agreeing to do so collectively is illegal.
