In a significant shift within the enterprise artificial intelligence (AI) landscape, Anthropic has emerged as the leading provider of large language models (LLMs), surpassing OpenAI. According to a recent report by Menlo Ventures, Anthropic now commands 32% of the enterprise LLM market, while OpenAI's share has declined to 25%. (menlovc.com)
This development marks a dramatic change from 2023, when OpenAI held a dominant 50% market share, and Anthropic accounted for just 12%. The rapid ascent of Anthropic underscores a broader trend in the AI industry, where enterprises are increasingly prioritizing performance and reliability in their AI solutions.
Anthropic's Rise to Prominence
Anthropic's success can be attributed to several strategic initiatives and technological advancements:
- Innovative Model Releases: The introduction of the Claude 3.5 Sonnet model in June 2024 set a new benchmark for AI performance. This was followed by the release of Claude 3.7 Sonnet in February 2025, which further solidified Anthropic's reputation for delivering cutting-edge AI solutions. (menlovc.com)
- Focus on Code Generation: Anthropic has made significant inroads in the coding domain, capturing 42% of the enterprise coding market. This is double the share held by OpenAI, indicating a strong preference among developers for Anthropic's tools when building software or integrating AI into their products. (menlovc.com)
- Strategic Funding and Valuation: In March 2025, Anthropic secured a $3.5 billion funding round, tripling its valuation to $61.5 billion. This substantial investment has enabled the company to expand its research and development efforts, further enhancing its AI offerings. (ft.com)
OpenAI's decline in enterprise market share from 50% to 25% over two years highlights the competitive pressures in the AI industry. Despite maintaining a strong presence in consumer applications, with over 2.5 billion prompts sent to ChatGPT daily, OpenAI faces challenges in retaining its enterprise clientele. (techcrunch.com)
Broader Industry Trends
The Menlo Ventures report also sheds light on other notable trends:
- Google's Growth: Google has gained significant ground, now holding 20% of the enterprise LLM market, driven by the adoption of its Gemini models. (menlovc.com)
- Preference for Closed-Source Models: Enterprises are increasingly favoring closed-source AI models, with 87% of workloads running on such platforms. This preference is due to factors like performance, security, and support. (menlovc.com)
- Decline in Open-Source Adoption: The use of open-source models in enterprises has decreased from 19% to 13% over the past six months, indicating a shift towards proprietary solutions. (menlovc.com)
Anthropic's rise and OpenAI's decline in the enterprise sector reflect the dynamic nature of the AI industry. Enterprises are increasingly discerning in their choice of AI partners, prioritizing performance, reliability, and strategic alignment. This shift underscores the importance for AI providers to continually innovate and adapt to meet the evolving needs of enterprise clients.
As the AI landscape continues to evolve, companies like Anthropic that demonstrate a commitment to technological excellence and strategic growth are well-positioned to lead the market. Conversely, established players like OpenAI must reassess and refine their enterprise strategies to maintain competitiveness in this rapidly changing environment.
