Anthropic Files for IPO: Nasdaq Listing Under Ticker ANT

Anthropic, the maker of the Claude models, has moved to become a public company. A dedicated IPO site now hosts the founders' letter, a roadshow video, a fact sheet and the European prospectus. Shares of Class A common stock are expected to trade on Nasdaq under the ticker "ANT".

The timeline and the price range

The roadshow begins on November 10 (EST). Subject to regulatory clearance, the final share price is expected on November 18, with public trading starting November 19. Retail investors can request shares through participating brokerage platforms, though there is no guarantee any applicant receives all or any of the shares requested.

The pricing details are easy to misread. The European prospectus lists a maximum price of $120 per share, but that figure is a ceiling set to let European and Swiss retail buyers participate even if the U.S. price comes in higher than planned. The currently estimated U.S. range is $70 to $78 per share, and retail investors in Europe and Switzerland will pay the same final price as everyone else in the offering.

What the numbers say

The filing highlights a quarter (Q3 fiscal 2026) with revenue of $17.0 billion and an adjusted operating margin of 15 percent. Customers spending at least $100,000 on a trailing twelve-month basis number more than 11,900, which Anthropic says is over twelve times the count a year earlier. It also reports a more than fourfold gain in compute efficiency since the first quarter of 2025, measured as revenue divided by compute and infrastructure spending.

The headline net loss is $23.3 billion, but the company attributes $21.9 billion of that to a non-cash charge. As Anthropic's valuation rose, the fair value of its convertible notes, derivative liabilities and SAFEs rose with it, and accounting rules push that through the income statement. Readers should look at operating results separately from that one-time accounting effect.

Agentic work is the pitch

The customer stories in the roadshow lean heavily on agents rather than chat. Legora describes Claude powering agentic workflows for more than 1,500 law firms and in-house teams. Eli Lilly says over 50,000 employees have access to Claude Enterprise. Rakuten cites autonomous coding sessions of more than seven hours and a drop in feature time to market from 24 working days to five. Salesforce reports an 18-fold speedup on an API migration, and Walmart points to growth in its Sparky shopping assistant.

These figures are company-supplied and best read as marketing, not audited outcomes. Still, the pattern is consistent: the commercial story is built around coding agents and long-running automated tasks, the area where Claude Code has grown fastest.

Why developers should care

Anthropic is a public benefit corporation, a structure that lets the board weigh safety and societal goals alongside shareholder returns. Going public tests how far that commitment holds under quarterly reporting and market pressure. The amended certificate of incorporation and bylaws are among the published documents, and governance-minded readers will want to read how control and mission are protected after the listing.

For teams building on Claude, a public Anthropic means regular, audited disclosure of finances, compute commitments and risk factors. That makes it easier to judge vendor stability, pricing direction and how heavily the company depends on a few large infrastructure partners. It also puts Anthropic in public view alongside the other frontier labs competing on models, tooling and enterprise contracts.

What to watch next

• Where the final price lands relative to the $70 to $78 estimate, and how the stock trades on day one.
• How the 15 percent adjusted operating margin holds as compute spending grows.
• Whether the fair-value charges recur or fade once the company is listed.
• Any changes to API pricing, rate limits or enterprise terms as public-market expectations set in.

The prospectus and fact sheet are the primary documents. Anyone considering buying shares, or committing a product roadmap to Claude, should read them directly.
