Anthropic's annualized run-rate revenue reached $47 billion by mid-May 2026, surpassing Salesforce's $41 billion and positioning it as the second-largest pure-play software company after Microsoft. The company's rapid growth since its first dollar of revenue three years ago has been remarkable, with run-rate revenue climbing from $9 billion at the end of 2025 to $47 billion within five months, according to saastr.com.
The progression of Anthropic's revenue run-rate has been swift: $9 billion at the end of 2025, $14 billion in February 2026, $19 billion in March, $30 billion in April, $44 billion in early May, and $47 billion by mid-May. These figures were disclosed alongside its Series H funding round and represent the most recent month multiplied by twelve, a standard measure in software revenue reporting. The company has been transparent in these disclosures to avoid securities fraud, saastr.com reported.
Anthropic's growth trajectory places it ahead of major software companies such as Adobe ($25 billion), Intuit ($19 billion), ServiceNow ($14 billion), and Workday ($9.5 billion). The only public software company with a larger run-rate is Microsoft, whose software and cloud business generates around $300 billion. Projections suggest Anthropic's run-rate could reach between $70 billion and $90 billion by December 2026, underscoring its rapid ascent in the software industry.
Anthropic's run-rate revenue milestone was confirmed in its Series H fundraising disclosures in mid-May 2026, marking a significant benchmark in its growth. This places Anthropic firmly as a dominant player in the software sector, second only to Microsoft in annualized revenue run-rate among pure-play software companies.
