Anthropic Overtakes OpenAI in Enterprise LLM Market with 32% Usage Share

Anthropic’s AI models have surged past OpenAI to lead the enterprise Large Language Model (LLM) market, capturing 32% of usage share compared to OpenAI’s 25% [1]. This marks a dramatic reversal from 2023, when OpenAI held a dominant 50% of the enterprise market, while Anthropic had only 12% [1]. The shift reflects a growing preference among businesses for models tailored to complex operational needs, particularly in areas like coding, where Anthropic secures 42% of enterprise usage—more than double OpenAI’s 21% [1].

The rise of Anthropic is attributed to the successful deployment of its Claude Sonnet 3.5 model in June 2024 and the subsequent release of 3.7 in February 2025. These models are praised for their extended context windows, reduced hallucinations, and superior handling of multi-turn conversations—features critical for software development and other intricate tasks [1]. Enterprises increasingly value the reliability and enterprise-grade focus of Anthropic’s offerings, aligning with its emphasis on “Constitutional AI” for safer, more aligned outputs [1].

In contrast, OpenAI continues to dominate the consumer market, with over 2.5 billion daily prompts for ChatGPT, but has seen a steady decline in enterprise adoption since 2023 [1]. OpenAI’s broader strategy appears focused on maintaining its stronghold in consumer-facing applications, while Anthropic has carved a niche in the enterprise sector with specialized capabilities.

The broader enterprise AI landscape also shows a strong shift toward closed-source models, with proprietary solutions from companies like Anthropic and OpenAI capturing more than half of enterprise usage. Open-source models, though still valued for their flexibility, have seen declining adoption in enterprise workloads, from 19% in early 2025 to 13% by midyear [1]. Google has also shown growth in enterprise AI usage, signaling a diversifying competitive environment.

Businesses seeking to adopt AI must now consider not only general-purpose models but also specialized ones like those offered by Anthropic. Key factors include integration capabilities, data governance, security, and the ability to support complex workflows. As the market evolves rapidly, companies must remain agile, continuously evaluating new models and strategies to stay competitive.

Anthropic’s rise underscores the importance of addressing specific enterprise needs with tailored solutions. With the rapid iteration of advanced AI models, the focus is shifting from raw computational power to real-world applicability and integration efficiency [1]. For enterprises, this trend presents both opportunities and challenges, emphasizing the need for strategic AI partnerships that align with long-term operational and security goals.
