Anthropic Sets $70-$78 IPO Range, Offering Up to $64.35B

By Tom Whitfield

Anthropic’s revised IPO could raise approximately $64.35 billion at $78 per share, based on the amended registration statement the company filed with the Securities and Exchange Commission on November 10, 2026.

The amended S-1/A sets a $70 to $78 price range for 825 million Class A shares. Gross proceeds include both newly issued shares and shares sold by existing holders, so the headline total exceeds the cash available to Anthropic.

What changed after banks received the first pricing details?

Anthropic initially circulated IPO pricing details to banks. The company later said the information was “inaccurate” and pulled it back in a second email.

On November 10, the updated S-1/A replaced the earlier blank price range with the revised range and share count. Anthropic declined to comment on the reversal.

Banks now have a filed pricing framework, while the withdrawn email no longer governs the offering.

How much money reaches Anthropic?

The revised structure separates 801.35 million newly issued Class A shares from 23.65 million shares that existing shareholders will sell. At $78, the primary sale could produce approximately $62.5 billion for Anthropic.

Proceeds from the secondary shares will go to the selling shareholders, not the company. Across both portions, gross proceeds could reach $64.35 billion at the top of the range.

The headline proceeds figure therefore overstates the capital Anthropic itself could receive.

What valuation does the new range imply?

The updated terms imply a fully diluted valuation of approximately $1.404 trillion at $78 a share. Prospective buyers had reportedly discussed a valuation near $2 trillion earlier, leaving the revised top-end figure below those discussions.

Anthropic’s May funding round set a $965 billion post-money valuation. The $1.404 trillion implied by the IPO represents a premium of about 45 percent to that May mark.

The public terms reset the valuation below earlier buyer expectations but well above the company’s private funding level.

Who is backing the offering privately?

The filing also sets out a $26 billion private placement of Anthropic’s non-voting Class N shares at the IPO price. Seven companies have agreed to participate: Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC.

Because the Class N purchase price matches the IPO price, the seven buyers would enter at the same offering reference point as public investors. Their shares would carry no voting rights, and the placement would remain separate from the 825 million-share Class A sale.

For semiconductor readers, the participant list includes Nvidia, AMD, Broadcom, Micron and TSMC, alongside Google and Microsoft. The private placement gives those seven companies exposure to Anthropic at the IPO price while keeping their Class N shares distinct from the Class A sale.

The private placement adds a committed $26 billion equity transaction before any public share trading.

How large is Anthropic’s revenue base?

Anthropic reported third-quarter revenue of approximately $17 billion in the updated filing. It also reported $33.2 billion for the first nine months of 2026.

The reported revenue totals provide a scale for the valuation debate. They do not settle how investors will price the IPO.

Revenue is substantial in absolute terms, but final pricing rests on demand for the revised terms.

When will the shares trade?

CNBC, citing people familiar with the plans, reported that Anthropic planned to price the offering on November 18 and begin trading on November 19. Those dates come from media reporting rather than a confirmed timetable in the SEC filing, and they remain subject to change.

If the schedule holds, trading would begin before Thanksgiving. The amended filing has already fixed the proposed $70 to $78 range and 825 million-share offering, but it has not fixed the final IPO price.

The reported launch date remains provisional, while the amended filing provides the firmer commercial terms. The November 18 pricing will show whether demand supports the $70 to $78 band and its $1.404 trillion top-end valuation.
