A recent report from Ramp's AI Index reveals that Anthropic has overtaken OpenAI in the enterprise artificial intelligence sector, capturing 34.4% of the market compared to OpenAI's 32.3%. This marks a significant shift, as it is the first time Anthropic has led the rankings. The growth is primarily driven by the success of Claude Code, Anthropic’s AI coding assistant, which has resonated with developers and engineering teams since late 2025. In May 2025, only 9% of businesses were utilizing Anthropic's services, but this figure surged by 26% over the next year, while OpenAI's share slightly declined. The findings suggest a growing willingness among companies to explore various AI models, influenced by factors such as price, performance, and specialized tools. Ara Kharazian, an economist at Ramp, emphasized the rapid changes in the AI landscape, noting that the pace of development allows new entrants to disrupt established leaders quickly. Additionally, Anthropic is reportedly in discussions to raise at least $30 billion in funding, valuing the company at over $900 billion.
