Anthropic IPO Could Come in September, But It Has a Massive Risk Factor

Anthropic plans to let early investors and staff sell stock in its upcoming market debut, according to a recent report by The Information. SpaceX gave its own backers no such option in June. The prospectus should land soon after Labor Day on September 7.

That document sets out the risks and the finances before anyone can buy. Anthropic IPO Departs From Musk’s SpaceX Structure Big listings can sell two kinds of stock: New shares raise money for the company. Existing shares pay early backers instead.

SpaceX sold only the first kind. Its pricing release covered 555,555,555 new shares at $135 each. Not one came from an existing holder. Underwriters then took another 83,333,333.

That brought the total to 638.9 million shares and roughly $86 billion, still the largest listing ever. Every dollar went to the company, with the filing estimating that Musk kept about 82.4% of the voting power once trading began.
