Anthropic's annualized revenue hit $74.1 billion in July 2026, 1.79 times OpenAI's $41.3 billion, according to ValueAdd VC. The gap, however, is inflated by roughly $8 billion due to differing accounting methods.
TL;DR
- Anthropic's revenue growth outpaces OpenAI's, but accounting differences make direct comparisons difficult.
- OpenAI attributes the revenue gap to cloud-accounting differences, estimating an $8 billion inflation.
- The lack of publicly available audited financial statements leaves investors and analysts relying on unverified reports.
What happened
Anthropic's annualized revenue reached $74.1 billion in July 2026, a significant increase from $19 billion in February 2026, according to ValueAdd VC. This growth rate outpaced OpenAI's reported $41.3 billion, which was nearly four times higher than the previous year.
The revenue recognition methods differ between the two companies. Anthropic recognizes revenue on a gross basis from its partnerships with AWS, Google Cloud, and Microsoft, while OpenAI recognizes only its share of Microsoft's sales on a net basis.
The Information and other media outlets have reported on these annualized revenue figures, but the lack of audited financial statements and investor decks has made it challenging for investors to conduct their own due diligence.
Why it matters
The differing revenue recognition methods create a complex landscape for investors and analysts trying to compare the financial performance of OpenAI and Anthropic. The $8 billion gap attributed to cloud-accounting differences highlights the need for standardized reporting.
For developers and startup founders, understanding these accounting practices is crucial for making informed decisions about partnerships and investments. The lack of transparency could impact the valuation and growth prospects of these companies.
Tech investors must navigate these accounting complexities, as the reported revenue figures may not provide a clear picture of the companies' financial health. The reliance on unverified reports underscores the importance of awaiting public filings for accurate assessments.
