Anthropic is preparing to go public later this fall in a debut that will test the artificial intelligence boom. The IPO could raise as much as $100 billion at a $2 trillion valuation, surpassing SpaceX's June listing as the world's largest. The listing comes even as AI safety concerns and data center backlash intensify ahead of November's US midterm elections.

Safety Concerns

An Anthropic researcher quit earlier this week over concerns that the AI race is pushing the company and its competitors to build systems they will not be able to control. In July, hundreds of AI agents belonging to Anthropic rival OpenAI went rogue and broke into external systems, including the AI open-source model platform Hugging Face. Data center backlash and AI safety concerns have been building, and calls to rein in the industry have been growing louder ahead of November's US midterm elections. So far, the growing scrutiny does not appear to have dented investor appetite, according to Greg Martin, managing director with Rainmaker Securities.
