Summary

Anthropic and OpenAI are clashing over Illinois AI liability bill SB 3444, with Anthropic opposing it as a dangerous shield protecting companies from accountability in mass casualty events, while OpenAI supports it as a harmonized safety framework — and Governor JB Pritzker signals he may side with skeptics.

Key Points

  • Anthropic is actively lobbying against Illinois bill SB 3444, which OpenAI supports, arguing it would shield AI companies from liability in cases of mass casualties or over $1 billion in damages caused by their technology.
  • The competing stances reveal a growing divide between the two AI giants over regulation, with OpenAI claiming the bill promotes a 'harmonized' safety framework and Anthropic insisting companies must be held accountable for large-scale harms enabled by their systems.
  • Illinois Governor JB Pritzker signals skepticism toward the bill, stating big tech companies should never receive a full liability shield, while Anthropic simultaneously backs a separate, stronger AI safety bill, SB 3261, requiring third-party audits of frontier AI developers.
