Anthropic Targets $88.5 B Fundraise in Record-Size IPO and Private Placement

Anthropic filed an updated S-1 on Tuesday that outlines a dual-track capital raise combining an initial public offering with a concurrent private placement. The combined effort could bring in as much as $88.5 billion, a sum that would dwarf most historic market debuts and give the San Francisco-based AI firm a war-chest for its next phase of growth.

The IPO component proposes to sell just over 800 million shares at a price range of $70 to $78 per share. At the top of that range, the public offering would generate roughly $62.5 billion, positioning it as the largest IPO ever after SpaceX’s $75 billion offering. The filing sets a fully diluted valuation ceiling of $1.4 trillion, which, while below earlier market expectations of around $2 trillion, would still rank Anthropic as the second-largest valuation at a public debut, trailing only SpaceX’s June listing.

In addition to the public sale, Anthropic expects to secure about $26 billion through a private placement that will close immediately after the IPO. The private round lists a roster of technology heavyweights, including AMD, Broadcom, Google, Micron Technology, Microsoft, Nvidia and TSMC, underscoring broad industry confidence in the company’s AI platform. Together, the two tranches represent a total offering of 825 million shares, of which 23.6 million are being sold by existing shareholders.

Financial disclosures released alongside the filing show Anthropic’s revenue surged to $33.2 billion for the first nine months of the year, up from $2.5 billion in the same period a year earlier. The company also reports that revenue grew from zero at commercial launch in early 2023 to $17 billion for the quarter ending September 30, 2026, a rate the firm describes as the fastest enterprise adoption in history. Despite the top-line growth, Anthropic remains unprofitable, posting an operating loss of $1.3 billion for the nine-month period, down from $5.2 billion a year earlier. Net loss widened to $104 billion, compared with $25.1 billion in the prior year.

For founders and investors, the scale of Anthropic’s planned raise signals both the appetite for AI infrastructure capital and the high cost of scaling such platforms. The influx of cash will likely fund expanded compute capacity, talent acquisition and further product development, while also setting a benchmark for future AI IPOs. As the company prepares to list on Nasdaq under the ticker “ANT” later this month, market participants will watch closely to see whether the valuation and capital raise translate into sustainable profitability and whether the model can be replicated by other AI startups seeking public market exits.
