What happened
Anthropic's official IPO page confirms the concrete mechanics and timeline of its public offering. The roadshow began November 10 (EST), the final share price is expected to be set on November 18 (EST) subject to regulatory clearance, and shares are expected to begin publicly trading on November 19 (EST) on Nasdaq under the ticker symbol ANT. The company is offering Class A common stock at an estimated initial price of $70 to $78 per share in the U.S. offering. The European prospectus states a maximum public offering price of $120 per share, which the source explains is deliberately set above the estimated range so European and Swiss retail investors can still participate if the final U.S. price exceeds the current estimate; the final European and Swiss retail price will equal the final U.S. offering price, excluding brokerage fees, commissions, or currency conversion costs. Retail investors can request shares only through participating brokerage platforms by submitting an indication of interest, with the platform confirming eligibility and, on the first day of trading, allocation. The source states there is no guarantee any investor will receive all or any of the shares applied for. The page also discloses that net loss includes a $21.9 billion non-cash charge related to a change in the fair value of convertible notes, derivative liabilities, and SAFEs, attributed to an increase in the company's valuation. Anthropic describes itself as a public benefit corporation dedicated to securing AI's benefits and mitigating its risks.
Anthropic's official IPO page states that the IPO process begins with a roadshow starting November 10 (EST), that the final share price is expected to be set on November 18 (EST) subject to regulatory clearance, and that shares are expected to begin publicly trading on November 19 (EST). The stock is Class A common stock, trading on Nasdaq under the ticker symbol ANT.
The estimated initial public offering price in the U.S. offering is between $70 and $78 per share of Class A common stock. The European prospectus separately states a maximum public offering price of $120 per share; the source explains this was set above the estimated range to allow European and Swiss retail investors to participate in the global offering even if the final U.S. price exceeds the current estimate. The final offering price in the European and Swiss retail offerings will equal the final U.S. offering price, and brokerage fees, commissions, or currency conversion costs are not included.
Retail investors can request shares only through a participating brokerage platform: they must have an active account, submit an indication of interest, and the platform confirms eligibility on request and allocation on the first day of trading, expected November 19. The source states there is no guarantee that any investor will receive all or any of the shares applied for, and applicants should be ready to purchase all shares for which they apply. Shares bought in the IPO are purchased at the offering price; shares bought after trading begins are purchased at the prevailing market price.
The page discloses that net loss includes a $21.9 billion non-cash charge related to a change in the fair value of convertible notes, derivative liabilities, and SAFEs, attributed to an increase in the company's valuation. Anthropic describes itself as a public benefit corporation dedicated to securing AI's benefits and mitigating its risks, and states its belief that AI is one of the most consequential technologies in human history. The source directs investors to review the prospectus, a regulatory filing covering the business, financial statements, risk factors, management, use of proceeds, and offering details.

Why it matters
This is the authoritative primary confirmation of the offering terms for one of the most closely watched AI companies, and it converts weeks of IPO speculation into documented numbers and dates. The $70 to $78 per-share range is the first official pricing anchor, although the total implied valuation cannot be calculated from this source because the share count offered is not stated here; that remains an explicit unknown. The $21.9 billion non-cash charge is a concrete illustration of how Anthropic's rising private valuation flows through its financial statements, a detail investors will scrutinize in the prospectus. The structure of the offering also matters practically: retail participation is possible only through participating brokerages, requires an indication of interest, and carries no allocation guarantee, while the $120 European maximum price is a procedural ceiling, not the expected purchase price. Because Anthropic frames its entire corporate purpose around as a public benefit corporation, the offering also tests whether public markets will underwrite that governance structure at scale. All figures and dates above are the source's own claims; none are independently verified here.
This is a primary-source confirmation of pricing and timing for a major AI company's public offering, replacing prior reporting about expected plans with documented terms: a $70 to $78 estimated price range, a November 18 pricing date, and a November 19 expected trading debut.
The total implied valuation cannot be derived from this source because the number of shares offered is not stated on this page; that remains unknown from this material alone.
The $21.9 billion non-cash charge tied to convertible notes, derivative liabilities, and SAFEs shows how Anthropic's private valuation increase affects reported net loss, a financial detail prospective investors will weigh against the offering price.
Access conditions are concrete but conditional: retail participation requires a participating brokerage, an indication of interest, and platform-confirmed eligibility, with no allocation guarantee. The $120 European maximum price is a procedural ceiling, not the expected purchase price.
Anthropic's public benefit corporation framing ties the offering directly to its AI-safety mission, making this a test of how public markets value mission-structured AI companies. All claims here come from the company's own IPO page and are not independently verified.

What to watch next
Watch whether the final price, expected November 18, lands within, below, or above the $70 to $78 range, since pricing depends on regulatory clearance, investor demand, and market conditions per the source. The first day of trading on November 19 will show initial market reception, and retail investors will learn their allocations through their brokerage platforms that day. If the final U.S. price exceeds the estimate, observe how the $120 European maximum price mechanism accommodates European and Swiss retail participation. The share count and implied valuation, not stated on this page, should appear in offering documents. The prospectus disclosures, including the $21.9 billion non-cash charge and risk factors, will invite closer financial scrutiny as pricing approaches.
