Anthropic Files for IPO Targeting $1 Trillion With Claude's $80B Run Rate

Anthropic has filed an updated prospectus for a Nasdaq listing under the ticker ANT. Goldman Sachs and Morgan Stanley lead the offering, which could become the largest technology IPO on record and give public investors their first detailed view of Claude’s revenue, costs and infrastructure commitments.

The price range remains preliminary. Anthropic and its underwriters will set the final price after gathering investor orders, subject to market conditions and completion of the SEC process. The central question is whether rapid growth in developer and enterprise usage can support the company’s valuation and nearly $900 billion in future purchase and lease commitments.

The deal can reach $100 billion

Anthropic plans to offer 825 million Class A shares at $70 to $78 each, producing gross public proceeds of $57.75 billion to $64.35 billion. The offering alone would exceed Saudi Aramco’s roughly $29.4 billion record IPO.

At the top of the range, the base offering would raise $64.35 billion, the underwriter option would add about $9.65 billion, and the strategic placement would contribute another $26 billion. Combined gross proceeds would reach about $100 billion. Anthropic estimates net company proceeds of roughly $84.6 billion to $93.7 billion if underwriters exercise their full option. Existing holders receive the proceeds from their 23.6 million shares.

The valuation depends on the share count used:

• Basic post-offering value: Roughly $916 billion to $1.02 trillion, based on about 13.09 billion shares outstanding.
• Fully diluted value: Up to $1.404 trillion at $78 per share, including securities that may convert into common stock.
• Previous private value: $965 billion in Anthropic’s May financing.
• Earlier reported target: About $2 trillion before the recent reset in AI stocks.

Google, Nvidia, AMD, Broadcom, Micron, Microsoft and TSMC have agreed to buy the $26 billion Class N placement at the IPO price. Those shares carry no voting rights, will remain unregistered through the offering and have no underwriter lock-up. Anthropic also plans to allocate about 20% of the public offering to retail investors, compared with the typical 5% to 10% range.

Usage revenue powers the curve

The S-1 amendment reports nearly $17 billion in revenue for the quarter ended September 30, 2026. Revenue reached $11.6 billion in the preceding quarter and $1.4 billion in the third quarter of 2025, producing reported year-over-year growth of 1,127%.

The annualized run rates extrapolate shorter periods and do not represent recognized annual revenue. They nevertheless show how quickly usage expanded during 2026.

Metered consumption generated $13.1 billion, or 80% of revenue, during the six months ended June 30. Subscriptions contributed $3.2 billion, or 20%. Developer and enterprise workloads therefore drive most of the business, tying Anthropic’s results closely to token usage across its API and products such as Claude Code.

Accounting charges bury the operating signal

Anthropic reported a $104 billion net loss for the first nine months of 2026, including a $94.3 billion noncash fair-value charge. The charge reflects increases in the estimated value of convertible notes and related derivatives as Anthropic’s equity valuation rose.

GAAP requires those changes to pass through net income before the instruments settle or convert. The expense consumes no cash when recorded, although the underlying securities can still produce dilution or require repayment.

• GAAP operating income was $974 million in the second quarter.
• GAAP operating loss was $567 million in the third quarter.
• Company-defined adjusted operating income was $2.5 billion in the third quarter, equal to a 15% margin.
• Third-quarter net loss was $23.3 billion, driven largely by convertible-note accounting.

The gap between GAAP and adjusted operating results reflects expenses excluded under Anthropic’s definition, so the two measures serve different analytical purposes. The filing attributes part of the sequential deterioration in GAAP operating performance to higher short-term compute prices and noncash matching charges.

Compute contracts dwarf current revenue

Anthropic had about $895.4 billion in purchase and lease commitments at the end of September, compared with $146.6 billion in liquidity. The commitment total equals roughly 13 times annualized third-quarter revenue of about $68 billion, or 11 times the company’s October run rate. Actual cash requirements depend on delivery dates, lease schedules and the terms of each contract.

• Compute providers: Anthropic has approximately $417 billion in future obligations covering cloud services, data centers and the equipment inside them.
• SpaceX: Once all contracted capacity is available, Anthropic expects to pay about $3.1 billion per month for access to Nvidia-powered compute, equivalent to $37.2 billion a year.
• Amazon: Amazon’s notes convert into Class N shares at the IPO, subject to an ownership cap that Amazon may waive. Any remaining balance converts quarterly or becomes payable in cash at maturity.
• Default exposure: Failure to repay the Amazon notes or amounts due under the amended and restated credit agreement would trigger a default.

These contracts secure the capacity Anthropic needs to train models and serve customer traffic. They also increase the financial cost of weak utilization: if token demand slows while contracted capacity comes online, gross margins and cash flow would absorb the difference.

Market pressure trimmed the pitch

The $70 to $78 range sits below earlier expectations. The Wall Street Journal reported that major investors expected Anthropic’s proposed $1.5 trillion valuation to fall after a sell-off in AI stocks, with one investor suggesting a figure closer to $1 trillion. Anthropic had reportedly considered a valuation near $2 trillion several months earlier.

A preliminary version of the terms proposed selling 866.7 million shares at $70 to $80. That version was circulated to bankers and later withdrawn. The filed range reduces both the share count and the maximum price, placing the basic valuation near the company’s May private-market level.

Policy and talent add uncertainty

Anthropic’s risk disclosures identify government action, litigation, employee retention and corporate security as material concerns:

• Government policy: A February 2026 presidential directive and a Department of War supply-chain risk designation prompted legal challenges from Anthropic.
• Pending litigation: A district court granted summary judgment largely in Anthropic’s favor. A divided D.C. Circuit panel later denied its petition for review by a 2-to-1 vote, and Anthropic has requested an en banc rehearing.
• Employee retention: Large equity awards held by a co-founder and early employees vest substantially at the IPO, potentially affecting retention and the eventual supply of tradable shares.
• Recruiting and security: Competitors directly solicit Anthropic employees, immigration restrictions may narrow the hiring pool, and the company reports threats to employee safety and attempts to obtain confidential information.

Public reporting will expose the trade-offs

Existing holders will gain a public reference price and a path to liquidity after applicable restrictions expire. At the basic post-offering valuation, Anthropic’s range straddles the $965 billion price from its May financing. The strategic investors in the Class N placement add equity exposure to a major customer while strengthening their commercial ties to its infrastructure spending.

Developers and enterprise customers will gain quarterly data on the economics behind Claude. Several indicators will show how the IPO affects the platform:

• API prices, volume discounts and contract terms
• Token consumption and subscription growth
• Capacity, latency, availability and rate limits
• Cost of revenue and the gap between GAAP and adjusted margins
• Cash usage and the schedule for compute commitments
• Dependence on individual cloud, chip and data-center suppliers

Anthropic’s growth supports a valuation near $1 trillion only if usage continues expanding fast enough to absorb its contracted infrastructure. The IPO filing supplies the figures public investors will use to test that premise quarter by quarter.
