Looking at the 2025 revenue projections, we’re witnessing a fascinating divergence in how the two leading AI companies are approaching the market.
While OpenAI commands $12 billion in annual recurring revenue compared to Anthropic’s $5 billion, the underlying business model dynamics reveal a more complex competitive landscape.
OpenAI’s consumer subscriptionbusiness generates a staggering $5.5 billion annually, more than Anthropic’s entire company revenue.
This isn’t just a revenue stream—it’s a powerful moat. ChatGPT has become the Kleenex of AI, the default brand that millions associate with artificial intelligence itself. When people say “I asked AI,” they usually mean ChatGPT.
Consumer usage generates training data and feedback loops
Network effects emerge as ChatGPT becomes the standard for AI interaction
Anthropic’s $0 billion in consumer revenue signals either a strategic decision to avoid this market or an acknowledgment that competing with ChatGPT’s brand power would be prohibitively expensive.
The API Revenue Surprise: David Beats Goliath
The most striking revelation in this data is the API revenue comparison:
Despite having less than half of OpenAI’s total revenue, Anthropic has actually surpassed OpenAI in API revenue. This suggests that developers and businesses building on top of AI infrastructure prefer Claude for certain use cases, particularly in coding and technical applications.
The Concentration Play: Coding as the Killer B2B Application
Perhaps the most important insight: $1.4 billion of Anthropic’s API revenue comes from just two clients—Cursor and GitHub Copilot. This represents nearly 50% of their API business and 28% of their total revenue.
This extreme concentration reveals several critical insights:
AI-assisted coding has emerged as the first true “killer app” for B2B AI, with developers willing to pay premium prices for productivity gains
Anthropic’s Claude has technical advantages in code generation that the market leaders value over alternatives
The risk/reward profile is extreme—losing either client would be catastrophic, but owning the coding vertical could be transformative
