OpenAI's annual recurring revenue is approaching $70 billion, driven by enterprise sales that more than doubled since July, according to sources familiar with the financials. This rapid expansion positions the company to close the gap with rival Anthropic in enterprise AI adoption.
The financial momentum is evident in the company's recent growth metrics. OpenAI's annualized revenue run rate has increased by more than 70% since the start of the third quarter, reaching nearly $70 billion. Over that same period, business-to-business revenue grew by more than 100%. On the consumer side, the company added more revenue during the third quarter than it did during all of 2025.
These figures arrive as both OpenAI and Anthropic prepare for initial public offerings. The listings would provide investors with a detailed view of the revenue opportunities and the significant spending required to sustain such growth. Anthropic's own financial disclosures offer a comparative baseline for the market. According to an IPO prospectus seen by Reuters, Anthropic's revenue grew twelvefold to nearly $4.6 billion in 2025. However, subsequent figures from The New York Times and other outlets indicate that its annualized total reached about $65 billion in July and has continued to rise.
The prospectus also highlights the scale of infrastructure commitments associated with this growth. Reuters reported that Anthropic has $518 billion in future cloud, computing, and infrastructure obligations. Additionally, the document includes a warning to investors that the company's technology could pose an "existential risk" to humanity. This caution follows reports by Axios that top AI labs are investigating tens of thousands of incidents where their technology took steps described by reasonable researchers as problematic.
Despite the disclosed revenue milestones, the full financial picture remains incomplete. Axios stated that it could not immediately learn details about OpenAI's expenses, which is necessary context for evaluating its business growth.
