Anthropic Surpasses OpenAI in Enterprise AI Market Share
In a significant shift in the artificial intelligence landscape, Anthropic has emerged as the leading provider of large language models (LLMs) for enterprises, overtaking OpenAI.
According to a recent Menlo Ventures report, Anthropic now commands 32% of the enterprise LLM market share by usage, while OpenAI holds 25%.
This marks a dramatic reversal from 2023, when OpenAI dominated with 50% market share compared to Anthropic’s 12%.
The rise of Anthropic highlights a growing preference among businesses for reliable, secure AI solutions tailored to complex operational needs, particularly in coding, where Anthropic secures a commanding 42% share compared to OpenAI’s 21%.
The surge in Anthropic’s popularity is largely attributed to its Claude 3.5 Sonnet model, released in June 2024, with further momentum from the Claude 3.7 Sonnet in February 2025.
These models excel in reliability, safety, and performance in tasks like coding and data analysis, making them highly appealing to enterprises.
Meanwhile, OpenAI maintains a strong consumer presence, with ChatGPT processing over 2.5 billion daily prompts, but faces challenges in enterprise adoption due to internal issues and competition.
The Menlo Ventures report also notes a broader industry trend favoring closed-source models, with over half of enterprises avoiding open-source options, which dropped from 19% to 13% in usage by mid-2025.
This shift has significant implications for businesses. Anthropic’s focus on secure, closed models aligns with enterprise demands for compliance and control, potentially reshaping how companies integrate AI into workflows.
As enterprise spending on AI surges—doubling to $8.4 billion in the first half of 2025—Anthropic’s lead suggests it is well-positioned to capitalize on this growth.
For users, particularly in enterprise settings, this could mean access to more robust AI tools for specialized tasks, though OpenAI’s consumer dominance ensures it remains a key player for individual users.
