According to the source, Anthropic is considering allowing existing shareholders to sell shares at IPO

On 28 August, according to sources cited by The Information, Anthropic was considering allowing existing shareholders to sell part of their existing shares in IPOs, unlike the practice of large technology companies, such as SpaceX (SPCX.O), where IPOs did not allow shareholders to sell shares. This may allow early investors, executives and employees to deliver part of their wealth. According to the source, Anthropic plans to publicly disclose the IPO book after Labor Day (7 September) in the United States and expects to hold investor days in mid-September for potential investors and research analysts. IPO is likely to take place as soon as possible in late September or early October, but may still be delayed。
