Anthropic Surpasses OpenAI in Business Adoption and Automates 90% of Internal Coding

Anthropic has surpassed OpenAI in business customer adoption for the first time, according to data from fintech firm Ramp's May 2026 AI Index. Among Ramp's surveyed business clients, 34.4% are paying for Anthropic's services—up 3.8% from the previous month—compared to 32.3% for OpenAI, which saw a 2.9% decline. Overall AI adoption among these businesses reached 50.6%, marking a modest 0.2 percentage point increase. This shift highlights Anthropic's Claude AI gaining traction in corporate environments.

The company's rapid rise is underscored by internal transformations, as revealed by Anthropic's CFO Krishna Rao. In a recent interview with Business Insider, Rao disclosed that AI now generates 90% of Anthropic's code, dramatically boosting productivity. This automation is reshaping white-collar roles, moving employees from hands-on execution to oversight and management of AI outputs. Rao emphasized that such changes free workers from repetitive tasks, allowing focus on higher-level strategy and domain expertise.

Anthropic's product leadership echoes this momentum. Catherine "Cat" Wu, head of product for Claude Code and Cowork, described a three-phase evolution of AI assistance during the Code with Claude conference in San Francisco, as reported by TechCrunch. Last year focused on real-time, interactive coding support; today, it's about automating routines like customer service responses; and the next frontier is proactivity, where Claude learns user workflows and sets up automations without prompts. Wu envisions AI anticipating needs before users articulate them, deeply integrating into daily work.

This business lead positions Anthropic for potential massive growth, with reports suggesting a valuation nearing $950 billion. However, analysts note challenges ahead, including competition from established players and the need to maintain safe, reliable AI deployment. For businesses, the implications are profound: AI tools like Claude are not just aids but core productivity drivers, affecting sectors from software development to customer support. Employees across white-collar fields may increasingly manage AI agents rather than perform routine tasks, signaling a broader shift in the job market.

As AI adoption accelerates, companies like Anthropic are betting on proactive systems to stay ahead. Wu stressed that effective AI use still demands human oversight with specialized knowledge, countering fears of widespread job displacement. The next six months could see Claude advancing in workflow automation, further solidifying Anthropic's edge among enterprise users.
