Anthropic’s revenue surged more than 14-fold in the second quarter from a year earlier, underscoring the rapid commercial adoption of its Claude artificial intelligence models as the company prepares investors for a potential blockbuster initial public offering.
The AI company generated preliminary revenue of more than $11.5 billion in the quarter, compared with $787 million in the same period of 2025 and $4.73 billion in the first quarter of 2026, according to documents seen by Bloomberg News.
The figures are preliminary and could still change as Anthropic completes its financial reporting.

However, the sharp increase means Anthropic more than doubled revenue in just three months, highlighting the acceleration in demand for its AI products among businesses and professional users.
The growth comes as Anthropic competes directly with OpenAI for enterprise customers and developers.
Claude has gained traction among professionals, particularly in software development and coding, as companies increasingly deploy AI systems for tasks that previously required substantial human labor.
Anthropic’s ability to convert that adoption into recurring revenue has become necessary as the AI industry moves from demonstrating model capabilities to monetizing them at scale. The company’s second-quarter adjusted operating income was positive, according to the documents, suggesting that its rapidly expanding revenue base is beginning to improve its operating economics.
That is notable because leading AI developers face enormous costs for computing infrastructure, model training, data, and research. Sustaining growth while improving margins will be central to Anthropic’s public-market story.
Revenue Run Rate Passes $47 Billion
Anthropic’s annualized revenue run rate crossed $47 billion in May, according to the report.
OpenAI’s annualized revenue was above $40 billion around the same period, although the two companies may calculate their run rates differently, making a direct comparison difficult.
The latest figures suggest Anthropic has rapidly closed the commercial gap with OpenAI, which has long been the dominant consumer-facing name in generative AI.
The competition is increasingly extending beyond chatbot usage. Both companies are seeking to become core infrastructure for businesses by providing models through APIs, enterprise software and autonomous AI agents.
Anthropic’s strong performance is expected to strengthen its position in negotiations with customers and investors as the company seeks additional capital to fund the enormous infrastructure requirements of frontier AI development.
Potential IPO Could Reshape AI Market
Anthropic has been meeting with potential investors ahead of a possible mega-IPO, according to people familiar with the matter cited by Bloomberg.
The company has confidentially filed for a listing and is working with Morgan Stanley, Goldman Sachs and JPMorgan Chase on the potential offering, according to earlier reports. An IPO would give Anthropic access to public-market capital at a time when AI companies are committing hundreds of billions of dollars to data centers, advanced chips and other infrastructure.
The timing could also give Anthropic a first-mover advantage among major private AI laboratories seeking public listings. A potential offering later this year could come before an IPO from OpenAI, while Chinese AI company DeepSeek is also reportedly preparing for a potential listing.
Anthropic’s potential listing comes as investor appetite for technology and AI companies has helped revive the global IPO market. Companies have raised $256.4 billion through public listings this year, excluding blank-check companies and other financial vehicles, according to Bloomberg data. That is the highest annual amount since 2021.
For Anthropic, market conditions could provide an opportunity to raise substantial capital while giving existing shareholders a liquid market for their stakes.
The company’s rapid revenue growth could also support an ambitious valuation. However, public investors are likely to scrutinize whether its current growth rate can be sustained as competition intensifies and the cost of operating capable models rises.
The Bigger Test Is Profitability
Anthropic’s preliminary return to positive adjusted operating income is potentially as important as its revenue growth. The company is operating in a sector where revenue can rise rapidly while expenses remain enormous. Training and operating frontier models require vast amounts of computing capacity, while competition among AI laboratories is forcing companies to continually invest in larger and more capable systems.
Anthropic therefore needs to demonstrate that its growing enterprise customer base can generate sufficient recurring revenue to offset those costs.
The second-quarter figures provide an early indication that scale is beginning to work in its favor. If the company can maintain strong revenue growth while improving operating profitability, it could enter public markets with a substantially stronger financial profile than many earlier-stage AI companies.
Analysts predict the potential IPO would consequently be more than a fundraising event. It would provide the public market with one of its clearest opportunities to put a valuation on a leading frontier AI developer and test whether the extraordinary growth rates being generated by the industry can translate into durable profits.
