Anthropic Surpasses OpenAI in Enterprise AI Market Share
Anthropic has overtaken OpenAI in the enterprise AI market, capturing a 32% share amid soaring investments in AI solutions.
Key Points
- • Anthropic's market share increases to 32%, surpassing OpenAI's 25%.
- • Enterprise spending on LLMs hits $8.4 billion, doubling from the previous year.
- • Claude models from Anthropic have achieved a 42% share in coding applications.
- • Shift towards closed-source models sees open-source usage decline to 13%.
In a significant shift within the enterprise AI landscape, Anthropic has overtaken OpenAI in the large language model (LLM) sector, capturing 32% of the market share compared to OpenAI's 25%. This recent data from Menlo Ventures reveals that just two years ago, OpenAI dominated with a 50% market share while Anthropic lagged at 12%, marking a pivotal turn in enterprise preferences toward Anthropic’s offerings.
The surge in Anthropic's popularity is largely attributed to the successful launches of its Claude Sonnet 3.5 model in June 2024 and the follow-up Claude Sonnet 3.7 model in February 2025. These innovations feature extended context windows and reduced hallucinations, making them particularly advantageous for complex tasks such as coding. In fact, Anthropic holds an impressive 42% market share specifically in the coding sector, compared to OpenAI’s 21%.
According to the report, enterprise investment in AI has soared to $8.4 billion in 2025, doubling from $3.5 billion in 2024, reflecting a growing emphasis on performance when choosing AI solutions. Proprietary models, particularly from Anthropic and OpenAI, now account for over half of the market, with enterprises increasingly shunning open-source models—usage has dropped from 19% to only 13%. The landscape is further complicated by Google's 20% market share and Meta's Llama at 9%.
This shift is representative of a broader trend where enterprises are prioritizing not just the capabilities of AI models but also ensuring strict data governance and security in their operations. As technology partners and developers increasingly favor tailored solutions, Anthropic's rise illustrates a responsiveness to these specialized needs.
"The rapid change in market leadership underscores the importance of performance in production environments," said Tim Tully, a partner at Menlo Ventures. Looking to the future, the report predicts that long-horizon AI agents will play a crucial role in the advancement of enterprise AI, paving the way for a sector valued at over $10 billion.
As of now, while OpenAI maintains a strong presence in the consumer market—logging over 2.5 billion daily prompts for ChatGPT—it faces challenges in retaining enterprise clientele, which increasingly favor models that prioritize robust functionality and security.
