Anthropic Files for IPO with $80.7B Net Loss as Nasdaq Listing Nears

Key Insights

• Anthropic IPO plans advanced after the Claude developer filed its Form S-1 on Oct. 26.
• First-half revenue reached $16.3 billion, while noncash financing adjustments drove an $80.7 billion net loss.
• The filing outlined computing costs, AI safety concerns, and concentrated corporate governance ahead of the Nasdaq listing.

Anthropic IPO preparations advanced on Oct. 26 after the company publicly filed its registration statement. The Claude developer plans to list Class A shares on Nasdaq under ANT.

The filing revealed $16.3 billion in first-half revenue and an $80.7 billion net loss. However, financing-related accounting adjustments accounted for most of the reported loss.

Anthropic intends to sell Class A common stock through the proposed IPO. The company has not set the number of shares for sale or the offering price range. Its registration statement has not yet taken effect, and the company cannot sell the shares until it receives the required clearance.

Goldman Sachs and Morgan Stanley are leading the banks managing the offering. Anthropic plans to direct proceeds toward general corporate needs, including operating expenses, hiring, and computing infrastructure. The filing also allows the company to use part of the funds for investments or acquisitions.

Under the AI news, Anthropic’s founders would control 50.1% of voting power through a special share. A separate benefit trust would generally elect most directors.

The filing follows a May funding round that valued Anthropic at $965 billion. Investors have since considered higher valuations ahead of the proposed listing, although Anthropic has not announced an IPO valuation or confirmed a trading date.

Anthropic generated about $11.6 billion in revenue during the three months ended June 30, a 1,368% increase from the same quarter in 2025. Revenue for the first six months of 2026 totaled $16.29 billion, compared with $1.16 billion a year earlier.

The company sells access to its Claude models and related products to businesses and customers. Its offerings include tools for software development, workplace tasks and the use of AI models through application programming interfaces.

Corporate subscriptions form a growing part of its customer base. By the end of September, Anthropic had more than 11,900 customers generating at least $100,000 in annual revenue each. About 1,900 customers generated $1 million or more, while roughly 250 generated at least $10 million.

Anthropic recorded an $80.7 billion net loss in the first half of 2026, compared with a $13 billion net loss during the same period last year. Changes in the estimated value of convertible notes, derivative liabilities and related financing agreements accounted for about $72.4 billion of the latest reported loss.

The company’s operating loss narrowed to $693 million from $2.14 billion a year earlier. Anthropic also recorded about $974 million in operating income during the second quarter, following an operating loss in the preceding quarter.

Computing remains a major expense for the company. Anthropic expects spending on infrastructure and computing resources to keep rising as it trains models and serves customers.

Amazon, Google and Microsoft provide cloud infrastructure that supports parts of its business. The prospectus also identifies reliance on a limited number of large customers and distribution channels as a business risk.

Anthropic identified potential misuse of AI systems, failures in model controls and harmful behavior by advanced models among its risks. The filing also addresses economic disruption, cybersecurity threats and possible legal claims arising from the use of its technology.

The company competes with OpenAI, Google and other developers seeking business customers for their AI services. Anthropic warned that competition and the cost of developing advanced models could affect its future financial performance.

The IPO plans arrive as investors examine spending across the AI sector. OpenAI has also taken steps toward a possible public listing, while Anthropic continues expanding its Claude product line and enterprise services.
