Anthropic, the artificial intelligence company behind Claude, has reported third-quarter revenue of $16.8 billion, alongside an adjusted gross margin of 85%, as it prepares for a potential stock market debut later this year. The company also told prospective investors that it achieved adjusted profitability during the quarter, marking a significant milestone in its rapid expansion.
The financial update comes as Anthropic seeks to convince investors that its growing AI business can generate sustainable returns despite the enormous cost of computing infrastructure, model development and data centres.
Anthropic Revenue Jumps to $16.8 Billion
Anthropic’s third-quarter revenue increased from $11.6 billion in the second quarter of 2026, representing growth of approximately 45%. Revenue in the first quarter stood at $4.7 billion.
The latest quarterly figure is also more than three times the company’s full-year revenue of approximately $4.6 billion in 2025, highlighting the speed at which demand for its AI products has expanded.
Claude has gained traction among businesses and developers, particularly through AI-assisted coding tools and enterprise applications. The company’s products are increasingly being used to automate software development, analyse documents and support complex business workflows.
However, the sequential growth rate has slowed compared with the exceptionally rapid expansion recorded in the second quarter, raising questions about how quickly Anthropic can continue scaling its revenue.
85% Gross Margin and Positive Cash Flow
Anthropic told prospective investors that its gross margin reached 85% in the third quarter. It also reported an adjusted operating margin of more than 11% and positive free cash flow.
Gross margin measures the proportion of revenue remaining after direct costs associated with delivering products and services are deducted. A high gross margin can indicate that a business has the potential to scale efficiently, although it does not account for every operating expense.
The reported profitability is on an adjusted basis. Anthropic has not publicly detailed all the adjustments behind the figures, so they should not be interpreted as equivalent to audited profitability under standard accounting rules.
The company previously recorded substantial operating losses as it invested heavily in AI research, computing resources and infrastructure.
Claude’s Enterprise Growth Drives Demand
Anthropic’s growth has been supported by increasing adoption of Claude across enterprise software development and other professional applications.
Its Claude Code product has become an important part of its commercial strategy, helping developers write, review and modify software. Businesses are also using Claude for research, analysis and automation.
The company has benefited from investments and infrastructure partnerships involving Amazon and Google. Both companies provide computing resources while also competing in the broader AI market.
Anthropic’s reported net revenue retention rate of 900% suggests that existing customers have significantly increased their spending over time. However, the metric should be considered alongside customer concentration, pricing changes and the cost of serving growing workloads.
Anthropic Prepares for a Potential IPO
Anthropic is preparing for a possible initial public offering, with formal marketing reportedly expected to begin as early as the week of November 9, 2026. The company could potentially list before the end of the year, although the timing and terms remain subject to change.
Some investors have discussed valuations approaching $2 trillion. However, concerns about slowing growth, intense competition and substantial future infrastructure commitments could influence the final valuation.
Anthropic’s financial performance will be closely watched because its public listing could help establish how investors value major AI developers.
High Infrastructure Spending Remains a Risk
Despite its strong reported margins, Anthropic faces significant long-term financial commitments related to computing power, cloud services and data-centre infrastructure.
The AI industry is also becoming increasingly competitive, with companies racing to offer more capable models at lower prices. If pricing falls faster than usage grows, revenue and profitability could come under pressure.
Investors will therefore need to examine not only Anthropic’s headline revenue but also its cash generation, infrastructure commitments and ability to maintain margins as competition intensifies.
Summary
Anthropic reported third-quarter revenue of $16.8 billion, up approximately 45% from the previous quarter, alongside an adjusted gross margin of 85% and positive free cash flow. The Claude developer also reported adjusted profitability as it prepares for a potential IPO later in 2026. However, slowing growth, intense AI competition and substantial infrastructure commitments remain important risks for prospective investors.
