Anthropic has spelled out how heavily Big Tech is backing its stock market debut: seven companies — Google, Nvidia, Microsoft, AMD, Broadcom, Micron and TSMC — have committed to buy a combined $26 billion of shares in the maker of Claude in a private placement running alongside the IPO, at the final offering price. The detail appears in the company's roadshow presentation and was confirmed by Reuters and CNBC.
The split is the headline: Google and Nvidia are putting in $10 billion each, AMD $2.5 billion, and Broadcom, Micron, Microsoft and TSMC $1 billion each. These are the very companies that supply the chips, cloud and computing capacity Anthropic depends on — a vote of confidence from the base of the AI supply chain.
The private placement shares are Class N common stock, with no voting rights. In practice, the seven companies are putting money in without gaining a say over how Anthropic is run.
How much Anthropic could raise
Added to the public offering — 825 million Class A shares at $70 to $78, worth up to $64.35 billion — the total raise could reach $90.4 billion, which would make the debut one of the largest listings ever. The valuation reaches up to about $1.02 trillion on shares outstanding, or up to $1.4 trillion on a fully diluted basis.
According to CNBC, pricing is expected on November 18 and the Nasdaq debut, under the ticker ANT, on November 19. Those dates are reported, not stated in the filing with the SEC, which still needs to declare the registration effective before any shares can be sold.
The offering has also reached retail investors: Anthropic opened its Australian retail offer on Wednesday, November 11, closing on November 17, led by Commonwealth Bank's CommSec brokerage. There is no plan to list on the Australian exchange.
The roadshow launched on November 10, a day after an earlier document — 867 million shares and up to $69.3 billion — circulated among banks and was withdrawn by the company. Anthropic's annualized revenue reached about $81 billion at the end of October 2026, according to the prospectus.
