The AI industry has changed rapidly in recent years, with frontier companies like OpenAI and Anthropic seeing fast exponential growth in their revenues and valuations. This growth has important implications for AI’s trajectory: AI companies are continually improving their technology by scaling up compute and labor inputs, and their revenue and usage track how AI is already impacting the world.

To help researchers, policymakers, and the public understand these trends, we have created our AI Companies Data Hub. The hub tracks financial and operational metrics—revenue, funding, staff, usage, and compute spend—for the key companies developing frontier AI models, along with interactive visualizations. This supplements our data hubs on AI models and GPU clusters and provides a more holistic view of the resource inputs and economic impact of the AI industry.

Our data shows that the combined revenues of OpenAI and Anthropic grew around 10x since early 2024. OpenAI’s annualized revenue reached $13 billion in August 2025, up from $5 billion at the beginning of the year, while Anthropic’s revenue has grown explosively so far in 2025, increasing from $1 billion to $5 billion in seven months! This revenue growth reflects the rapid commercialization and diffusion of AI.

We also track funding rounds and valuations, showing the scale of capital flow into AI development. We’ve identified nearly $100 billion in debt and equity funding raised across frontier AI companies. Valuations have surged as well: OpenAI was recently valued at $300 billion, more than 10x its valuation from early 2023.

The AI Companies Hub also tracks operational metrics such as staff counts and product usage. Frontier AI companies have scaled from small startups to thousands of full-time staff. Additionally, their products now have hundreds of millions of users. OpenAI’s ChatGPT alone surpassed 700 million weekly active users by August 2025, processing over three billion daily messages.

Finally, we collected reports of AI companies’ aggregate, operating compute expenses. OpenAI’s cloud compute bill in 2025 will reportedly exceed $15 billion, around 3x higher than their compute spending in 2024!

We hope that the new AI Companies Data Hub will be a valuable resource for anyone interested in understanding the companies leading frontier AI development. Start exploring the data now — and stay tuned as we expand our coverage to new companies and datasets!
