A new report shows that AI research lab Anthropic has become the top choice for businesses using LLMs, overtaking OpenAI. 

According to data from Menlo Ventures, Anthropic now holds 32% of the enterprise LLM market based on usage, while OpenAI has dropped to second place with 25%.

This is a major shift from just two years ago. In 2023, OpenAI led the market with 50% usage among enterprises, while Anthropic only had 12%. 

Since then, Anthropic’s popularity has steadily grown, while OpenAI’s enterprise usage has sharply declined. Google has also seen more business adoption of its models, though it still trails behind both.

Anthropic is particularly dominant in the coding space. It now commands 42% of the enterprise coding market, twice as much as OpenAI, which holds just 21%. (Via: TechCrunch)

This suggests that developers are increasingly turning to Anthropic’s tools when building software or integrating AI into their products.

A key reason for Anthropic’s rise is the release of its Claude 3.5 Sonnet model in June 2024, which was well-received for its performance. 

The launch of Claude 3.7 Sonnet in February 2025 only boosted usage further. These advancements helped convince more businesses to switch from competitors to Anthropic’s tools.

The report also confirms what many in the tech industry have been saying: that enterprise developers now prefer Anthropic’s Claude models over OpenAI’s ChatGPT. 

However, OpenAI still leads in consumer use — it recently reported more than 2.5 billion prompts sent to ChatGPT every day.

Menlo Ventures also found that most companies favor closed-source AI models (like those from Anthropic and OpenAI) over open-source alternatives. 

More than half of the surveyed enterprises said they don’t use open-source models at all. 

In fact, daily enterprise use of open-source models has dropped to just 13% as of mid-2025, down from 19% earlier this year. 

Meta continues to lead the open-source AI space, but usage is limited in corporate environments.

Do you think Anthropic’s rise shows that businesses value AI safety and reliability over flashy features? Or is this just a temporary shift that OpenAI can reverse with better enterprise products? Tell us below in the comments, or reach us via our Twitter or Facebook.
