Artificial intelligence startup Anthropic is seeing its revenue growth accelerate further. According to sources familiar with the matter, based on current business performance, the company's annualized revenue run rate had exceeded $65 billion as of the end of July, marking a more than seven-fold increase from levels seen at the end of 2025 and strengthening the case for a potential U.S. stock market debut as early as this autumn.

Insiders indicate that Anthropic's annualized revenue run rate reached approximately $65 billion by the end of July. The annualized revenue run rate, which extrapolates full-year revenue based on performance over a shorter period, does not equal actual revenue already realized for the year. The figures were disclosed in periodic business updates provided to investors.

The company's revenue expansion has been remarkably rapid. At the end of 2025, the annualized revenue run rate had just surpassed $9 billion. By May of this year, it had exceeded $47 billion, and by the end of July, it had climbed further to $65 billion. By this calculation, the revenue run rate has grown more than seven-fold in less than a year.

The fast-paced growth has further bolstered Anthropic's foundation for pursuing an initial public offering (IPO). Both Anthropic and OpenAI have confidentially filed for public listings, with Anthropic expected to potentially hit Wall Street as early as this autumn, likely ahead of OpenAI's own listing timeline.

Once viewed as a laggard in the generative AI race, Anthropic has rapidly expanded its market share in recent years through products like Claude, particularly gaining traction in AI coding and handling complex enterprise tasks. By comparison, as previously reported, OpenAI's annualized revenue run rate has recently exceeded $40 billion. However, since the two companies may calculate this metric differently, the figures are not directly comparable.

The company's preliminary revenue data for its most recent full quarter also shows robust growth. According to related documents, quarterly revenue exceeded $11.5 billion, compared to just $787 million in the same period of 2025 — representing a year-over-year increase of more than 14-fold.

More notably, Anthropic also achieved positive adjusted operating profit in that quarter, indicating that profitability is beginning to improve even as the company rapidly scales its revenue.

With Anthropic's revenue run rate breaking through $65 billion and its quarterly adjusted operating profit turning positive, the competitive dynamic with OpenAI is extending beyond model performance and user growth into commercialization capabilities and capital markets. Should Anthropic complete its IPO as early as this autumn as planned, its rapid revenue growth and improving profitability are expected to serve as key benchmarks for investors evaluating the company's valuation.
