Anthropic overtakes IPO-bound OpenAI, hits record $30 billion RRR as Claude usage soars

Anthropic has recently shared news that could raise concerns for IPO-bound OpenAI. The company announced that its run-rate revenue (RRR) has now surpassed $30 billion, highlighting the growing popularity of the company. Run-rate revenue is a financial projection method that estimates future annual revenue based on current performance. The figure is remarkable, especially considering that the company reported its RRR at $9 billion at the end of 2025.

This development could become a major cause of concern for OpenAI, as the IPO-bound company appears to be lagging behind a relatively newer entrant. OpenAI’s run-rate revenue as of March 2026 stands at $25 billion. Anthropic, which was founded in 2021, is relatively new to the space compared to OpenAI.

Claude AI driving Anthropic’s growth

For those wondering how Anthropic achieved this growth, the answer lies in Claude, a large language model developed by the company. The model has gained widespread popularity among users. Its Claude Code tool, an artificial intelligence system that can generate computer code based on prompts, has gone viral and shown record growth.

The company said that in February, over 500 business customers were spending more than $1 million each on an annualised basis. That number has now exceeded 1,000, doubling in less than two months.

Expanding infrastructure to meet demand

Anthropic is also expanding its capacity to accommodate anticipated demand. The company has recently signed a new agreement with Google and Broadcom for multiple gigawatts of next-generation TPU capacity. According to the company, the new infrastructure is expected to come online starting in 2027. The expanded compute capacity will power its frontier Claude models.

New features make Claude more versatile

Anthropic has also recently added several new features to Claude to make it more versatile. From dispatch to computer use and remote work capabilities, Claude Code can now do far more than before, including testing apps it builds from scratch without needing to ask for your permission.

Computer use gives the AI greater capability when it comes to autonomous tasks. The system can now open applications, navigate interfaces, run tests, identify bugs, and fix them autonomously.

Meanwhile, the rise in popularity has also brought some issues. Users have recently reported that they are unable to fully utilise Claude because their token limits are being consumed faster than expected.

The company acknowledged the issue and issued an immediate fix. After a thorough investigation on April 3, it said that most of the high consumption, or “burn”, of tokens was caused by a small number of specific usage patterns that required large amounts of tokens. It has promised to roll out more efficiency improvements.
