Anthropic PBC is telling prospective investors that its second-quarter revenue jumped at least 14-fold from a year earlier, according to documents seen by Bloomberg News.
The Claude chatbot maker reported preliminary revenue of more than $11.5 billion for the second quarter of 2026, compared with $787 million in the same period of 2025 and $4.73 billion in the first quarter of this year. The documents also show the company posted positive adjusted operating income for the quarter — a first. Deliberations are ongoing and the figures could be revised; a representative for Anthropic declined to comment.
The rapid growth comes as Anthropic battles longtime rival OpenAI for corporate customers. Once considered an underdog in the artificial intelligence race, Anthropic has seen a surge in professionals adopting its software for tasks including coding. Its annualized revenue run rate crossed $47 billion in May; OpenAI's run rate is above $40 billion, Bloomberg News reported, though the two figures may not be calculated the same way.
The company is meeting with investors ahead of a potential mega-IPO, people familiar with the matter said in July. Anthropic has filed confidentially for a listing and is working with Morgan Stanley, Goldman Sachs and JPMorgan Chase on the offering. An IPO this fall would see Anthropic debut before OpenAI and before Chinese rival DeepSeek, which is also preparing for a public listing.
Anthropic is seeking to tap the public market's ample funding capacity to maintain its lead over OpenAI and others, as AI companies spend hundreds of billions of dollars developing frontier models. The AI race has reignited the IPO market: listings this year have raised $256.4 billion, excluding blank-check companies, the most in a single year since 2021, according to Bloomberg data.
