Spark Capital’s Anthropic stake could be worth tens of billions of dollars

Business Insider reports that Anthropic’s IPO filing points to unusually fast potential gains for early investors. Spark Capital’s stake could be worth tens of billions of dollars. Bessemer Venture Partners has invested $800 million since 2024 for an almost 1% stake. The report contrasts that timeline with SpaceX, whose first venture investors backed it in 2002.
