Anthropic IPO Preview: Everything You Need to Know

Founded in 2021 by former OpenAI members including Dario Amodei and Daniela Amodei, San Francisco-headquartered Anthropic is a company focused on frontier artificial intelligence research and development.

With its Claude series of large models at its core, the company generates revenue through individual subscriptions, enterprise services, and APIs, with enterprise customers serving as a key revenue source. As of September 30, 2026, the company had more than 11,900 enterprise customers generating $100,000 or more in revenue over the past 12 months, including over 1,900 customers generating $1 million or more.

As of November 4, the company has not yet determined the final offer price, number of shares to be issued, or fundraising scale.

According to a Wall Street Journal report on November 3, Anthropic plans to launch its investor roadshow as early as next week, aiming to complete its listing the week before Thanksgiving (November 26), though the specific timing remains subject to adjustment.

Meanwhile, according to Yahoo Finance calculations under relevant SEC rules, the company could begin trading as early as November 16; if referencing SpaceX's (SPCX) previous 23-day period from public filing to its first trade, the listing date could be November 18.

In terms of valuation, the market previously discussed the possibility of the company listing at a valuation of around $2 trillion. According to reports, some institutional investors have suggested capping the valuation at $1.5 trillion to $1.6 trillion, and the final offering valuation has yet to be determined.

Based on trailing 12-month revenue of approximately $35.282 billion for the period ending September 30, 2026, a valuation between $1.5 trillion and $2 trillion corresponds to a price-to-sales ratio of roughly 42.5 to 56.7 times. Even at a $1.5 trillion valuation, the market would still need to price in high expectations for the company's future growth.

According to the S-1 filing, Amazon (AMZN) and Google parent company Alphabet (GOOGL) each hold more than 5% of Anthropic's shares, making them its major institutional shareholders.

Among them, Amazon holds approximately $6.2 billion in unconverted convertible notes, with its post-conversion ownership subject to a 12% cap; Alphabet's ownership cap is 14.99%, though it may apply for a waiver. The prospectus has not yet disclosed the final actual ownership percentages of the two companies.

In addition, venture capital firms such as Spark Capital, Menlo Ventures, Coatue Management, and Lightspeed Venture Partners, as well as funds managed by Fidelity and Blackstone, also hold shares in Anthropic.

Some shareholders have already cashed out prior to the IPO. In April this year, Anthropic completed a tender offer of approximately $4.66 billion for its stock, with participating sellers including CEO Dario Amodei, President Daniela Amodei, and other executives.

In the first nine months of 2026, Anthropic's revenue reached $33.242 billion, up 1,206% year-over-year. During the same period, computing and infrastructure expenses were $18.808 billion, accounting for approximately 56.6% of revenue.

In the third quarter, Anthropic's revenue reached $16.956 billion, up 47% quarter-over-quarter, slowing from a growth rate of approximately 144% in the second quarter. During the same period, the company recorded a GAAP operating loss of $567 million, while adjusted operating profit stood at $2.463 billion, with the adjusted operating margin falling from 19% in the second quarter to 15%.

The company stated that approximately $5 billion in short-term computing power procurement expenses and $2 billion in non-cash matching donation expenses weighed on third-quarter profit margins.

Of the GAAP net loss in the first nine months, approximately $94.324 billion stemmed from changes in the fair value of convertible notes, derivative liabilities, and SAFE-related financial instruments, which were primarily non-cash book losses rather than actual cash expenditures.

According to updated offering documents, as of September 30, 2026, and thereafter, Anthropic's total procurement and lease commitments were approximately $895.4 billion. Of this amount, $447.5 billion is expected to be incurred by the end of 2030, while commitments due over the next 12 months stand at approximately $69.8 billion.

Not all of these commitments require immediate payment; some agreements include termination rights or performance conditions, and certain leases have not yet commenced.

As of September 30, the company held $95.6 billion in cash and cash equivalents, $36.3 billion in short-term investments, and an available credit facility of $14.8 billion, bringing total liquidity to approximately $146.6 billion, which falls short of its disclosed long-term procurement and lease commitments.

If AI demand falls short of expectations, a decline in compute utilization could further intensify the company's financial and cash flow pressures.

Following its listing, Anthropic primarily faces three major risks.

Intensifying competition in the AI industry. Peers such as OpenAI and Google continue to launch new models and enterprise AI products, which could exacerbate price competition and expose Anthropic to API price cuts, customer churn, and margin pressure.

Uncertainty in enterprise customer demand. Although Anthropic's enterprise client base is growing rapidly, its revenue remains subject to customer procurement scale, model usage, and contract renewals. In the first nine months of 2026, the top five customers contributed approximately 25% of revenue, making customer concentration and shifts in purchasing patterns key areas to monitor.

Special equity structure limits common shareholders' influence. Anthropic employs a Public Benefit Corporation (PBC) structure and a multi-class share system. The Class F special shares held by Founder LLC command 50.1% of total voting power, while the Long-Term Benefit Trust (LTBT) holds the authority to appoint and remove a majority of the board members.

Post-listing, investors will need to focus on revenue growth, adjusted operating margin, computing costs, and operating cash flow. Whether the company can translate its massive computing investments into sustained revenue and profit, as well as whether its IPO valuation is reasonable, will be crucial for investors assessing its investment value.
