Anthropic IPO disclosures unveiled on October 26, 2026, showed revenue of $16.29 billion for the first half of the year, highlighting the Claude maker’s expansion in business AI. But different treatment of cloud-partner sales makes its revenue difficult to compare directly with OpenAI’s, while substantial losses leave profitability an unresolved question.

Key Takeaways

  • Anthropic’s first-half 2026 revenue exceeded its full-year 2025 total of $4.59 billion.
  • Cloud-marketplace accounting differences prevent a straightforward revenue ranking against OpenAI.
  • A large non-cash charge drove Anthropic’s net loss far above its operating loss.

Anthropic IPO puts enterprise growth in focus

Anthropic reported revenue of $4.59 billion in 2025, up from $386 million in 2024, before reaching $16.29 billion in the first six months of 2026. Demand for Claude’s business applications, particularly software-development tools, has supported that expansion.

Anthropic’s guide to Claude Code developer workflows describes a terminal-based agent that can read repositories, edit files and execute commands. Its uses include debugging errors, writing and running tests, and reviewing code changes. Those capabilities explain the product’s role in software development; the guide does not establish its sales performance.

OpenAI, meanwhile, has a broad consumer presence through ChatGPT and has expanded into business software, developer tools and AI agents. The competitive question extends beyond user reach to how effectively each company converts demand into paying business.

Why headline revenue does not settle the comparison

OpenAI reported $6.7 billion in revenue for the second quarter of 2026. That quarterly figure covers a different period from Anthropic’s first-half total and should not be treated as a like-for-like comparison.

There is also an accounting distinction. Anthropic records the full value of certain cloud-marketplace sales as revenue and books the platform fees separately. OpenAI excludes some similar cloud-partner sales from its revenue figures.

As a result, headline sales alone cannot establish which company has the larger underlying business. Comparable reporting periods and consistent treatment of partner transactions would be needed for a cleaner assessment.

Operating losses and non-cash charges tell different stories

Anthropic reported a $693 million operating loss for the first half of 2026. Its net loss was much larger, at $80.7 billion, largely because of a non-cash accounting charge tied to an increase in the estimated value of bonds that may eventually convert into shares.

The distinction matters: the net loss does not mean Anthropic spent $80.7 billion in cash during the half. The operating loss more closely reflects the gap between operating revenue and expenses, but it is not itself a measure of cash generated or consumed.

Both Anthropic and OpenAI face substantial computing and infrastructure requirements. Rapid sales growth therefore does not, by itself, establish that either company has reached sustainable profitability.

Cloud partners provide reach and create dependence

Amazon and Google’s cloud marketplaces accounted for 47% of Anthropic’s sales to customers in 2025. Both companies provide computing infrastructure, invest in Anthropic and compete with it in AI.

Those relationships give Claude access to businesses already buying cloud services, while concentrating an important part of its distribution in two powerful partners. OpenAI also relies on major technology relationships, including Microsoft.

For prospective shareholders, the filing makes the central trade-off clearer: enterprise demand is expanding quickly, but partner dependence, computing commitments and the cost of delivering AI remain material parts of the business model.
