Anthropic’s annualized revenue has reached approximately $45 billion, surpassing OpenAI’s estimated $33 billion by at least 35 percent, according to The Information. The gap is being driven primarily by enterprise adoption of Claude Code and agentic AI deployments across Fortune 500 companies.
The Reversal
The shift happened fast. At the end of 2025, Anthropic’s annualized revenue was approximately $9 billion, less than half of OpenAI’s, according to KuCoin/BlockBeats citing The Information’s reporting. Since then, Anthropic’s revenue has grown roughly fivefold while OpenAI’s grew by approximately 50 percent.
Both companies are experiencing strong growth. But the structural composition of that revenue tells the real story. Approximately 85 percent of Anthropic’s revenue comes from enterprise and developer customers, according to Forbes. OpenAI’s revenue mix runs in the opposite direction, with roughly 85 percent tied to ChatGPT consumer subscriptions and approximately 95 percent of those users paying nothing.
Why Enterprise Agents Matter
Anthropic’s enterprise revenue advantage maps directly to its agentic product strategy. Claude Code, the company’s autonomous coding agent, has become the fastest-growing AI coding tool in the world. Claude-based agent deployments across regulated industries (financial services, healthcare, legal) generate three to five times more revenue per token than consumer chat queries, according to Forbes.
Over 500 companies now spend more than $1 million annually on Anthropic’s Claude platform, and eight of the Fortune 10 are customers, Anthropic disclosed during its latest funding round, as Forbes reported.
The Information also reported that Anthropic may have already achieved quarterly operating profitability, a milestone the company previously projected for Q2 2026. Forbes noted that Anthropic projected $10.9 billion in Q2 2026 revenue with a $559 million operating profit, arriving two years ahead of what the company had told investors last summer.
The Cost Structure Gap
OpenAI’s computing expenditure is projected to reach $121 billion in 2028 alone, with a projected loss of $74 billion that year, according to Forbes citing FastCompany and WSJ reporting. Anthropic projects $17 billion in positive cash flow in 2028 on $70 billion in revenue, with gross margins approaching 77 percent, Forbes reported citing TechCrunch.
The divergence is structural, not temporary. Enterprise query patterns are more deterministic and therefore cheaper to serve. Enterprise contracts are sticky. Consumer inference at massive scale without proportional revenue is expensive. SaaStr noted that Anthropic’s ARR had climbed from $1 billion to $14 billion in just 14 months — a trajectory that has sent a signal to investors beginning to price in agentic displacement of traditional SaaS.
The Agent Revenue Thesis
Anthropic’s revenue lead validates a specific bet: that agentic AI products generate more enterprise value than conversational chatbots. Claude Code, managed agent deployments, and Claude Cowork represent a product stack designed to replace human workflows at the enterprise level, not to serve as a consumer utility. The revenue numbers suggest that bet is paying off faster than anyone, including Anthropic itself, expected.
