Class Action Sues Four AI Labs Over Alleged 'AI Slowdown' Pact as Sherman Act Violation
rohanpaul_ai · x · 2026-09-20
A new class action lawsuit has been filed in a California federal court against four frontier AI labs, alleging that their coordinated limits on AI development violate Section 1 of the Sherman Act.
- The complaint traces the alleged agreement to September 12, when Anthropic CEO Dario Amodei urged industrywide coordination to limit unchecked AI progress; executives at three rival labs publicly supported parts of the proposal the same day, which plaintiffs characterize as acceptance of a common restraint.
- The core argument: paid subscribers expect continuing improvements in reasoning, coding, agents, and context windows, so slower capability growth equals reduced output; unilateral slowing risks losing customers, revenue, and talent, while collective restraint removes that competitive penalty.
- Plaintiffs seek to represent a nationwide class of subscribers paying for the four major AI assistants, requesting an injunction plus treble damages.
- The filing stresses it does not challenge unilateral safety testing, outside evaluations, environmental safeguards, or government regulation.
- Caveat: the suit remains an allegation, and public statements supporting safety goals do not by themselves establish an unlawful agreement.
