Anthropic Co-founder: AI Singularity Has Arrived

Jack Clark, co-founder of Anthropic, declared at the IMF 2026 annual meeting in Bangkok that the AI singularity has arrived. Speaking at the Per Jacobsson Lecture, he cited a tenfold increase in code output by Anthropic researchers and advances by AI in mathematics, biology and materials science.

Clark highlighted benchmark results: Claude Opus 5.5 scored 67.7% on Humanity's Last Exam and 94 on FrontierMath, while GPT-6 Astra reached 98% on 50 unpublished physics problems. He noted that in several contested cases, the AI's derivations were confirmed correct after human experts rechecked their own answers.

He also described a future in which the global scientific workforce expands from about 10 million human scientists to a far larger cluster of virtual AI experts. Anthropic's economists have modeled a scenario in which U.S. GDP could reach $44 trillion by 2030 if AI-driven scientific discovery fully transforms economic activity. Clark said the first phase of the AI revolution, focused on data centers and compute, is nearing its end, and the second phase is moving into the physical world.

He warned that the risks are equally severe and called for serious rules and restraint in developing the technology.
