Anthropic’s planned IPO could turn Spark’s $75 million stake into $7 billion, while FTX has already exited
Anthropic is reportedly moving toward an IPO as early as November, with some existing and prospective investors discussing a valuation of about $1.5 trillion, according to Reuters and Bloomberg reports cited in the source material. That would be roughly 55% above the company’s $965 billion post-money valuation from its May Series H round. Bloomberg’s reporting, based on people familiar with the matter, points to large paper gains across Anthropic’s cap table, spanning early venture firms, sovereign wealth funds, and individual backers. Among the investors highlighted, Iconiq has put in more than $6 billion and its stake is valued at about $17 billion using the $965 billion benchmark. Spark Capital’s $75 million investment from 2023 is now worth about $7 billion on the same basis, while Menlo Ventures’ stake is pegged at about $14 billion. Sequoia Capital and Singapore’s GIC each hold roughly 1%, implying a value of about $9.65 billion at that valuation. FTX stands out for a different reason. Court filings from the exchange’s bankruptcy case show that FTX affiliate Clifton Bay invested $500 million in Anthropic in 2021, then sold the entire position in 2024 for about $1.34 billion during the bankruptcy process. Anthropic and most of the named investors declined to comment, according to Bloomberg.
