Anthropic plans to go public by mid-November at the earliest, with market discussions estimating a valuation of about 1.5 trillion USD

The artificial intelligence company Anthropic plans to go public as early as mid-November, with market discussions giving it an IPO valuation of about $1.5 trillion, approximately 55% higher than the $965 billion valuation from financing in May this year. Based on this potential valuation, Spark Capital invested $75 million in 2023, with a stake now valued at around $10.9 billion, having a valuation of about $5 billion that year and securing a board seat, making it the only known venture capital firm with a board seat. After an initial investment of $35 million, Sound Ventures added $400 million, co-founded by Guy Oseary and Ashton Kutcher, entering the market in 2023, with a stake valued at several billion dollars. Menlo Ventures has invested over $1 billion in total, with a stake valued at about $21.8 billion, including a $500 million Series D round, entering the market for the first time in May 2023.

Iconiq entered the market in 2025, investing over $6 billion in total, with a stake potentially valued at around $26.4 billion, with the valuation reaching $183 billion at the time of its first investment. Sequoia Capital began investing this year, with a total of about $3 billion, holding approximately 1% of the shares, valued at about $15 billion, having previously invested in OpenAI and xAI. The Singapore sovereign wealth fund GIC made its first investment in 2025, accumulating over $4.5 billion, holding about 1% of the shares, valued at around $15 billion. Former Google CEO Eric Schmidt invested tens of millions of dollars in 2021, holding about 1% of the shares, valued at around $15 billion.

FTX invested $500 million in 2021, initially holding 13.56% of the shares, which diluted to 7.84% in 2024. After bankruptcy liquidation, it sold all its shares, recovering about $1.3 billion, with actual earnings around $800 million. Based on the undiluted 7.84% and the $1.5 trillion valuation, the theoretical value is about $117.6 billion, approximately $116.3 billion higher than the actual selling price, with calculations not accounting for subsequent financing dilution. In 2024, FTX sold all its Anthropic shares in batches, with the first batch involving about $884 million in transactions with 24 buyers. The Abu Dhabi sovereign wealth fund Mubadala's affiliate ATIC bought about $500 million, Jane Street purchased $100 million, and a Fidelity fund bought $45 million. Lightspeed holds less than 2%, and Google, Amazon, NVIDIA, Microsoft, as well as Founders Fund, Coatue, Altimeter, and others have also invested, but public holding data is not complete enough to accurately calculate returns for each.
