Anthropic readies September prospectus as secondary market highlights AI IPO demand gap

Anthropic is preparing to file its IPO prospectus in late September, with a target listing in November and investment banks Morgan Stanley, Goldman Sachs, JPMorgan and Citi handling the transaction. Analysts are slated to meet with the company’s executives as the offering moves forward. Meanwhile, the secondary market for upcoming AI IPOs shows a stark contrast: Anthropic shares are in high demand, while OpenAI shares are viewed as more affordable for investors. The differing levels of demand underscore how scarce AI IPO shares have become.
