Anthropic plans to unveil its IPO prospectus after Labor Day and could list in late September or early October, The Information reported, citing people familiar with the process. The startup confidentially filed for a public listing earlier this year as investor demand for AI companies intensifies and it competes with OpenAI to reach the market. Anthropic is considering allowing existing shareholders to sell shares in the IPO, potentially distinguishing it from this year’s SpaceX and Cerebras offerings, which excluded such sales. It is also weighing lockup periods longer than the customary 180 days. Anthropic has raised at least $130 billion to fund its intensive computing needs and is expected to surpass the $86 billion raised by SpaceX in its June IPO, the report said. The split between newly issued shares and secondary sales remains unclear.
