AI Race Heats Up: Anthropic Challenges OpenAI's Growth
11 Apr
Summary
- Anthropic's business tool adoption rose significantly in March.
- OpenAI's business adoption remained flat, but with a larger user base.
- Anthropic's Claude chatbot downloads tripled globally in March.

Anthropic is making significant strides against OpenAI in the competition for paying business customers. In March, approximately one in three U.S. businesses utilized Anthropic's tools, marking a substantial increase from February. While OpenAI continues to lead in overall U.S. business adoption at 35%, its growth has plateaued.
This divergence is attributed to Anthropic's robust interest in its Claude Code products and automation 'plug-ins.' OpenAI, which experienced an explosive surge post-ChatGPT's November 2022 launch, now faces challenges in sustaining that initial rapid growth. Downloads for ChatGPT increased by a modest 5% in March, whereas Anthropic's Claude chatbot saw its global downloads triple to 21 million.
Further indicating a shift, ChatGPT's weekly active users in the U.S. declined month-over-month in March for the first time this year. Despite a prior dispute with the U.S. defense department, Anthropic announced reaching $30 billion in annualized revenue. Analysts observe a clear change in momentum, with business needs and model performance often outweighing regulatory concerns for companies.
OpenAI is implementing changes, including a management shake-up, to bolster its position ahead of potential IPO plans, reportedly refocusing on core offerings. Anthropic's strategy of targeting professionals and developers first is proving effective, expanding its adoption beyond early adopters into broader sectors like finance, information services, and even construction and hospitality.
