Anthropic moved a step closer to going public on Oct. 26, when the developer of the Claude chatbot publicly filed its Form S-1 registration statement. The company plans to list its Class A common stock on Nasdaq under the ticker symbol ANT.

The filing disclosed $16.3 billion in revenue for the first half of 2026 alongside a net loss of $80.7 billion, although most of the shortfall stemmed from financing-related accounting adjustments rather than core operations. Publicly filing an S-1 opens a company's detailed financial disclosures to review under the U.S. Securities and Exchange Commission's registration process, giving prospective investors access to the numbers before any shares can trade.

Offering Details Remain Open

Anthropic intends to sell Class A common stock through the proposed IPO, but it has not yet determined the number of shares to be offered or the price range. Its registration statement has not taken effect, and the company cannot sell shares until it receives the required clearance. Deal terms such as the share count and price range are typically finalized in subsequent amendments to the registration statement as the process advances.

Goldman Sachs and Morgan Stanley are leading the banks managing the offering. According to the filing, 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.

Concentrated Governance Structure

The prospectus shows that Anthropic's founders would control 50.1% of voting power through a special share, while a separate benefit trust would generally elect most of the company's directors. That would leave just under half of the voting power with other shareholders, including prospective public investors.

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

Second-Quarter Revenue Climbs 1,368%

Anthropic generated about $11.6 billion in revenue during the three months ended June 30, a 1,368% increase from the same quarter of 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 individual 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. Breakdowns of this kind are part of the detailed operating disclosure now available to outside investors through the S-1.

Net Loss Reaches $80.7 Billion

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. Because those charges arise from revaluing financing instruments rather than from operating activity, the headline net loss far exceeds the company's operating loss figures.

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, and Anthropic expects spending on infrastructure and computing resources to keep rising as it trains models and serves customers. Amazon, Google, and Microsoft provide the 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.

AI Safety and Competition Risks

Anthropic identified potential misuse of AI systems, failures in model controls, and harmful behavior by advanced models among its risk factors. 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. Remaining milestones include SEC clearance of the registration statement, disclosure of final deal terms, and confirmation of a trading date, none of which the company has yet announced.
