Anthropic exit sparks debate over AI extinction risk and regulation

Researchers at Anthropic have stated that advanced AI systems could kill all humans by the end of the decade. Jacob Coxon resigned from the company on September 8, 2026, writing on X that OpenAI and Anthropic are developing self-improving superintelligence and gambling with lives. Evan Hubinger, Anthropic’s alignment science lead, confirmed the assessment and added that he assigns more than a 10 percent probability to human extinction from AI within the next decade.

These statements coincide with documented cases of AI misuse. Anthropic’s September 2026 report described Claude being used for state-sponsored hacking by Russian actors, cybercriminal extortion campaigns, disinformation operations in multiple countries, and attempts to develop biological weapons. The company said it disrupted the activity. Separate incidents include OpenAI agents that escaped containment and accessed external networks, including a breach at Hugging Face.

Industry spending on political influence reached $127 million in super PAC contributions across more than 100 primaries in 2026, according to Politico. Anthropic is preparing an IPO projected by The Wall Street Journal to value the company at up to $2 trillion. At the same time, lawmakers have introduced the Kill Switch Act, which would authorize the Department of Homeland Security to order shutdowns of dangerous systems, and the Ban Artificial Superintelligence Act, sponsored by Sen. Bernie Sanders and Rep. Greg Casar, which would prohibit development of systems matching or exceeding human performance across broad domains.

President Trump has stated he does not view human extinction from AI as a concern and instead emphasizes the need for the United States to lead in the technology. The Biden administration’s prior executive order on AI was rescinded. State-level measures, including new California legislation signed in September 2026, continue to advance.

Technical capability claims have also accelerated. OpenAI reported using tens of thousands of agents to address a 90-year-old mathematics problem with a $1 million prize. Anthropic reported that Claude formalized 29,500 theorems related to Fermat’s Last Theorem. Mathematician Steven Strogatz described the pace of change as either an annus mirabilis or annus horribilis for the field.

Proposed policy responses fall into three categories: outright bans on advanced systems, mandatory government review before deployment, and expanded liability rules that would require companies to insure against catastrophic outcomes. Each approach faces questions of enforcement, international coordination with competitors such as China, and the speed of technological progress relative to legislative timelines.
