Anthropic's IPO filing reveals record gains for early investors

Anthropic has filed its S-1 for an IPO, positioning the AI company to break records with historic gains for early investors just three and a half years after its first major funding round. The filing confirms rapid scaling that challenges industry norms. Spark Capital, which led Anthropic's spring 2023 round, holds over 1% of the company, potentially worth tens of billions. Bessemer Venture Partners invested $800 million since 2024, its largest bet ever, despite initial skepticism over the $18 billion valuation. Anthropic has beaten OpenAI to the IPO, with the ChatGPT-maker expected to go public next year. The IPO comes amid broader AI industry debates over compute demand and data centers. Other recent deals include Intel's $2.3 billion acquisition of Classiq and Cognition's new valuation between $70 and 80 billion.
