Anthropic is reportedly lobbying the U.S. Congress in secret to advance an AI safety bill it primarily drafted, which sets an extremely high bar for federal government intervention in frontier AI models. Citing Politico, Reuters reported that Anthropic representatives have privately lobbied members of Congress on this draft legislation. According to the bill, the government could only intervene to prevent the release or use of an AI model if it poses a foreseeable, imminent risk—specifically, one that could cause over $1 billion in damages or lead to the death or serious injury of more than 50 people. Furthermore, the bill strictly limits regulatory authority to the Department of Commerce and federal courts, explicitly prohibiting any other U.S. government department, agency, or official from suspending the development, deployment, or internal use of AI models. Analysts believe that if this bill becomes law, it would grant frontier AI models a high degree of operational certainty in the U.S. market, with regulatory intervention risks strictly constrained by law.
