Speaking at the IMF and World Bank annual meetings in Bangkok on Saturday, Anthropic co-founder Jack Clark said an internal Anthropic model projects that AI could raise US economic output by nearly 50%, to about $44 trillion by 2030 from roughly $30 trillion today — a figure he conceded "sounds very crazy." He said the projection assumes continued technological progress and argued that international cooperation is needed to write "extraordinary and serious rules" for the technology, warning that policymakers' window to act is narrowing as AI advances faster than humans can follow. Clark, who is Anthropic's head of public benefit, also cast AI as a multiplier for scientific discovery while flagging misuse risks such as bioweapons, and acknowledged job losses in high-exposure areas like call centers and customer service. Reports noted Anthropic is preparing an IPO that could value it at up to $2 trillion; some Chinese tech outlets covering the talk cited unverified benchmark figures, such as 67.7% on Humanity's Last Exam for Claude Opus 5.5 and a 37% score on a Vals RSI index, which should be treated as promotional.
