OpenAI Tops $40 Billion in Annualized Revenue, Cuts Prices Ahead of IPO

Anthropic and OpenAI are competing to dominate the commercial market for generative artificial intelligence, expanding through model subscriptions, application programming interfaces and enterprise services. Annual recurring revenue, or ARR, extrapolates the current revenue pace over 12 months and is not the same as revenue already booked. Even so, the measure offers investors and customers a gauge of demand, business momentum and the companies’ ability to finance costly computing infrastructure.

As of July 2026, the latest data put Anthropic’s ARR at $74.1 billion, well above OpenAI’s $41.3 billion and giving the Claude developer a substantial lead in commercial scale. OpenAI is closing the gap rapidly, however, with its annualized revenue climbing nearly 30% over the past two months. The acceleration underscores intensifying competition between the two AI companies for enterprise customers, computing capacity and the revenue needed to support further model development.

OpenAI is evaluating an initial public offering, but Chief Executive Sam Altman reportedly insists the company must be valued at $1 trillion, an unusually high threshold for the technology sector. The enormous cost of training generative AI models, computing infrastructure and data centers means the timing of the listing will shape investor assessments of AI valuations and the industry’s ability to sustain funding.

The latest reports indicate that OpenAI, facing its valuation demand and continued heavy cash burn, is leaning toward delaying its IPO until 2027. Rival Anthropic has filed for a listing and could go public as early as 2026, potentially establishing the first pricing benchmark for AI companies. The White House is also stepping up its review of OpenAI’s next-generation GPT-5.6 model, adding regulatory uncertainty.

OpenAI plans to tap the corporate networks of four private equity firms, including TPG and Advent International, to integrate its models into large customers' workflows. The initiative could shape its enterprise AI market share and revenue growth, while also affecting its race with Anthropic to go public as early as 2026.

The latest proposal calls for a standalone company valued at $10 billion pre-money, with OpenAI planning to invest $4 billion. Some reports put its initial commitment at $1.5 billion. The venture would also acquire Tomoro and deploy forward-deployed engineers (FDEs) to help customers integrate AI systems, accelerating commercialization and preparations for an IPO.

OpenAI built a lead in the consumer market with ChatGPT, but Anthropic has rapidly closed the gap in the high-margin software development and enterprise markets with Claude Code and enterprise agent tools. Competition in generative AI has shifted beyond individual model capabilities to workflows, data permissions and deployment platforms. OpenAI’s ability to convert its 900 million users into paying customers with heavy computing needs will be critical to its revenue and IPO valuation.

In March 2026, Fidji Simo called on OpenAI to rein in its “side quests.” On March 24, the company announced it would discontinue the Sora consumer app, developer version and ChatGPT video features to focus on Codex and enterprise agents. OpenAI is targeting a fourth-quarter IPO at a valuation of about $1 trillion. On April 13, Chief Revenue Officer Denise Dresser outlined five strategic priorities, including Spud, Frontier and DeployCo.

OpenAI and Anthropic are competing for generative AI enterprise customers and cloud computing capacity. OpenAI Chief Revenue Officer Denise Dresser argues that Anthropic’s growth narrative rests on particular accounting methods and reliance on a single product. Her allegations also underscore intensifying competition between the companies for customers, funding and market valuations.

As of July 19, 2026, a leaked internal OpenAI memo showed Dresser accusing Anthropic of overstating its annualized revenue by about $8 billion and criticizing its computing capacity and product strategy. The memo also revealed that OpenAI plans to broaden its sales channels through Amazon and build a DeployCo deployment engine to accelerate enterprise adoption and market expansion.

Founded in 2015, OpenAI has expanded rapidly through ChatGPT and enterprise AI services. As it prepares for an initial public offering, the company has identified its reliance on Microsoft for cloud computing and commercial partnerships as a risk in its financial filings. Computing costs and partner concentration will directly affect its IPO valuation, profitability and operational resilience.

The latest filings show that OpenAI estimated its 2025 revenue at $13.1 billion, although training and deploying large AI models still require substantial capital expenditure. Its reliance on Microsoft could also become a focus of investor scrutiny. The company is expanding partnerships with Amazon and others to diversify its cloud infrastructure and commercial resources, reduce concentration risk and prepare for the IPO.
