Anthropic Withdraws $70-to-$80 IPO Price Range After Leak

Anthropic sent bankers an IPO filing late on November 9, 2026, showing plans to sell about 867 million shares at $70 to $80 each. The company quickly called the pricing details inaccurate and said the filing would be updated.

The correction became public within roughly 80 minutes after the first report went out around 8:20 p.m. ET. Anthropic did not say which numbers were wrong and declined to comment.

“inaccurate”

The official SEC filing remains the amended S-1 dated November 2, which showed a blank price range and a planned Nasdaq listing under the symbol ANT. The emailed copy listed 866,666,664 Class A shares, worth about $69.33 billion at the top of the range and $60.67 billion at the bottom.

The filing covers shares sold by both Anthropic and existing stockholders, so the figure combines new stock with shares held by current investors. Anthropic has not disclosed its post-IPO share count, so a valuation cannot be derived from the range.

Seven technology companies, including Google, Nvidia, AMD, Broadcom, Micron, Microsoft, and TSMC, were considering a combined $26 billion private placement alongside the IPO. It remains unclear whether that investment will proceed.

Google holds an option to buy up to $10 billion of Class N stock at the IPO price. Alphabet shares closed at $288.15, up 1.18%, in the regular session hours before the emails emerged.
