OpenAI Tops Anthropic by $1B in Q1 AI Revenue Race
OpenAI generated approximately $5.7 billion in revenue during the first quarter of 2026, putting it nearly $1 billion ahead of Anthropic. However, while OpenAI remains the market leader, Anthropic’s rapid momentum suggests the competitive gap may narrow much sooner than expected.
Anthropic’s Rapid Rise Reshapes Competition
Even though OpenAI holds the revenue lead, Anthropic is growing at an extraordinary pace. The company reportedly expects revenue to climb to $10.9 billion in the June quarter, marking a 130% jump from Q1. Consequently, that figure would surpass its entire 2025 revenue, which stood at roughly $6 billion.
At the same time, Anthropic appears close to a major milestone in profitability. If current projections hold, the June quarter would mark its first operating profit at an estimated $559 million. In contrast, OpenAI is projected to post a $14 billion loss in 2026 before reaching profitability in 2029.
Much of Anthropic’s momentum comes from Claude Code, its agentic coding platform, which scaled rapidly after launch. Within six months, it reached $1 billion in annualized revenue, while by February 2026, that figure had grown beyond $2.5 billion in run-rate revenue. Additionally, the company now serves more than 1,000 enterprise customers, each spending over $1 million annually.
OpenAI Faces Growth Pressure
Although OpenAI continues to generate more revenue overall, internal challenges have started to emerge. Reports suggest the company missed several internal monthly revenue goals this year. Moreover, it reportedly fell short of its target to reach one billion weekly active ChatGPT users.
Financial concerns have also surfaced around long-term expansion costs. As a result, leadership has reportedly discussed delaying a planned IPO from 2026 to 2027. Meanwhile, OpenAI’s enterprise business currently contributes around 40% of total revenue, with leadership aiming to raise that share to 50% by year-end.
AI Market Dynamics Continue to Shift
The broader AI market is changing quickly, and Anthropic appears to be capturing significant momentum. According to recent customer spending data, the company now attracts more than 73% of first-time AI software buyers. Furthermore, its annualized revenue run rate reportedly surged from $9 billion at the end of 2025 to $30 billion by April 2026.
CEO Dario Amodei described the company’s trajectory as “unbelievable” earlier this month. Simultaneously, Anthropic is reportedly raising more than $30 billion at a valuation above $900 billion, potentially setting the stage for its final private funding round before an IPO.
