Anthropic IPO: Revenue, losses, liquidity and 7 other things to know in historic filing

Anthropic confirmed it has applied to list its Class A common stock on the Nasdaq Global Select Market under the trading symbol "ANT".Artificial intelligence giant Anthropic has officially set the stage for one of the most anticipated Wall Street debuts in history.

In an official announcement and a Form S-1 statement filed with the US Securities and Exchange Commission (SEC) on October 26, 2026, the San Francisco-based research lab laid out its financial trajectory, governance framework, and massive infrastructure ambitions.Founded in 2021 by seven researchers, including Chief Executive Officer Dario Amodei and President Daniela Amodei, Anthropic is incorporated as a Delaware public benefit corporation (PBC) with a stated mission of the responsible development and maintenance of advanced AI for the long-term benefit of humanity.

As the company prepares to test the waters in the stock market, its preliminary prospectus offers an unprecedented look inside the economics of frontier AI: Hyper-growth revenueAccording to the IPO filing, Anthropic’s flagship AI, Claude, has experienced the fastest enterprise adoption of any technology in history.

After launching commercially with $0 in revenue in the first quarter of 2023, the company generated $41 million in full-year 2023.

Revenue then surged 841 per cent to $386 million in 2024, and jumped another 1,088 per cent to reach $4.6 billion in 2025.This momentum accelerated further in 2026 as for the six months ended June 30, 2026, revenue skyrocketed by 1,300 per cent year-over-year to $16.3 billion.

For the three months ended June 30, 2026, revenue grew 1,368 per cent year-on-year, while compute and infrastructure expenses rose 300 per cent.

Swing to non-GAAP profitability GAAP net losses remainThe S-1 filing reveals a stark contrast between Anthropic's operational cash generation and its bottom-line accounting figures.

On a non-GAAP basis, Anthropic swung to profitability in the first half of 2026, posting an adjusted operating income of $1,618 million and adjusted net income of $2,671 million for the six months ended June 30, 2026, compared to an adjusted net loss of $1,741 million in the first half of 2025.However, under standard GAAP accounting, the company reported net losses of $1.5 billion in 2023, $8.3 billion in 2024, $42 billion in 2025, and $80.7 billion for the six months ended June 30, 2026.According to the filing, these GAAP losses may be driven by non-operating accounting adjustments, including a $72.4 billion change in the fair value of convertible notes, derivative liabilities, and SAFEs in the first half of 2026, resulting from increases in Anthropic's enterprise valuation.

GAAP operating loss for the first six months of 2026 narrowed to $693 million.Enterprise adoption is expanding rapidlyDario Amodei-led company reported more than 11,900 customers generating at least $100,000 in trailing 12-month revenue as of September 30, 2026, up from more than 950 a year earlier.The company also had more than 1,900 customers generating at least $1 million in trailing 12-month revenue and approximately 250 customers generating at least $10 million.At the other end of the customer base, approximately 40 million customers individually generated less than $100,000 in trailing 12-month revenue.

The figures show that Anthropic has built a broad customer base while increasing the number of organisations spending substantial amounts on its AI products.Most revenue is usage-basedThe IPO filing highlights that Anthropic’s revenue is primarily consumption-based, a model the company refers to as ‘pay-for-intelligence’ or 'consumption,' where customers pay for intelligence services metered in tokens and priced according to the model selected, alongside monthly subscriptions.Because most revenue is usage-based and many top customers are not locked into long-term contracts, Anthropic noted that usage can fluctuate with seasonal holiday slowdowns in the summer and winter or shifts in customer budgets.“Consumption-based revenue increased from $288 million, or 75% of total revenue, for the year ended December 31, 2024, to $3.8 billion, or 83% of total revenue, for the year ended December 31, 2025, to $13.1 billion, or 80% of total revenue, for the six months ended June 30, 2026.

Subscription-based revenue increased from $98 million, or 25% of total revenue, to $789 million, or 17% of total revenue, to $3.2 billion, or 20% of total revenue, over the same periods,” the filing said.

900% revenue retentionExisting enterprise customers are expanding their usage at an extraordinary pace.

As of September 30, 2026, Anthropic recorded a net revenue retention rate of approximately 900 per cent.In the S-1 filing, Anthropic attributes this rapid expansion to enterprises embedding Claude into business-critical workflows and realising lower costs per task noting, for instance, that Claude Opus 5.5 reduced customer costs per task by approximately 40 per cent compared to Claude Opus 5, which in turn spurs greater usage.Five-class stock structureAnthropic is going public with what the filing describes as a novel capital and corporate governance structure featuring five classes of common stock: Class A, Class N, Class T, Class F, and Class E.

Class E shares, authorised for employees, carry limited voting rights and no economic rights.

Additionally, Anthropic contributed 846,840,960 Class N shares to the Anthropic Public Benefit Fund, and all seven co-founders have pledged to donate 80 per cent of their personal equity to charity.Substantial liquidityAnthropic has raised an aggregate of $141.1 billion of capital to date as of June 30, 2026.

Its liquidity position includes $112.4 billion in cash and cash equivalents and $19.3 billion in short-term investments, bringing total cash and short-term investments to $131.7billion.The filing said Anthropic had raised an aggregate $141.1 billion in capital by June 30, 2026.
