Anthropic IPO Orders Reach Six Times Shares on Offer as 825 Million-Share Sale Begins

Key Facts

Anthropic has begun its roadshow for its initial public offering, offering 825 million Class A shares in the deal, with an option for investors to buy an additional 123.75 million shares, according to its official prospectus. The company set an indicative price range of $70 to $78 a share and filed to list the shares on Nasdaq under the ticker ANT. By the end of Thursday, November 13, investor orders had reached six times the shares on offer, up from nearly twice the offering by the end of Tuesday, according to a Reuters report citing people familiar with the matter. The expansion of the order book reflects strong interest in the offering, while the final price and proceeds remain subject to the pricing outcome. The move comes as AI companies test investors’ ability to value rapid growth that requires large infrastructure commitments.

The transaction also includes a concurrent private placement in which seven technology companies will buy Class N shares worth a total of $26 billion at the same price set for the public offering, according to the prospectus. Anthropic said the buyers had agreed to these purchases “separately, not jointly.” The prospectus distinguishes between company shares and shares offered for sale by existing shareholders; under the proposed offering structure, Anthropic is selling 801,351,354 shares, while existing shareholders are selling 23,648,646 shares. The company will not receive proceeds from shares sold by those shareholders. This distinction between new issuance and shareholder sales means the company’s actual proceeds will differ from the total value of shares investors may buy.

The company said $186.2 billion of that total is tied to arrangements subject to pending conditions or termination rights that can be exercised before performance begins. It also expects to pay about $70.7 billion of its contractual commitments over the 12 months following September 30, 2026. These figures put some of the cost of expanding services at the center of investor assessments, alongside growth expectations. Anthropic says it expects to continue entering into new arrangements to secure computing capacity and infrastructure as its business expands.

The company relies on long-term agreements with computing providers. It committed to spending at least $110 billion with Amazon between May 2026 and April 2036, regardless of actual usage. It also committed to spending at least about $121.3 billion with Google between April 2026 and July 2033. Anthropic’s arrangements with SpaceX.AI are worth up to $120.5 billion for computing powered by Nvidia units, and the agreements run through 2029. The company expects capacity delivery to be completed in December 2026, at which point spending will approach $3.1 billion a month. These contracts link expansion plans to spending flows extending over years, with commitments that may be paid regardless of actual usage in Amazon’s case.

By contrast, the Associated Press reported that Anthropic’s revenue exceeded $16 billion in the first half of 2026, 14 times revenue in the same period a year earlier. But it said the company had yet to turn a profit, putting revenue growth alongside expansion costs in investors’ calculations. The news agency said shares of companies tied to building AI data centers led a sharp sell-off on Wall Street during the week before its report, published on November 10. A Reuters report on November 13 also said investors were weighing Anthropic’s ability to maintain its lead as competition from Google accelerates. Their questions include whether Claude can extend its advantage from coding into knowledge work, while the report described the company’s long-term competitive position as unresolved.

Before the roadshow began, an AP report published on November 10 said the offering included 825 million shares at a price range of $70 to $78 and estimated that a price at the midpoint of the range could raise more than $61 billion. That remains an earlier estimate, while the announcement of the roadshow did not include a final price. According to the indicative schedule in the retail prospectus filed with the U.S. Securities and Exchange Commission, the final price and offering results were scheduled to be published on November 18, 2026, with trading on Nasdaq to begin on November 19. The prospectus says the dates are estimates and may change. The pricing outcome and announced proceeds will mark the offering’s next milestone, as the company continues to secure the infrastructure it says it needs.
