URGENT UPDATE: New reports confirm that Anthropic has emerged as the leading provider of Large Language Models (LLMs) for businesses, overtaking OpenAI with a staggering 32% share of enterprise usage as of mid-2025. This significant shift has been detailed in a recent survey conducted by Menlo Ventures, an early-stage venture capital firm heavily invested in Anthropic.
This change matters now more than ever, as businesses increasingly rely on advanced AI for programming and productivity. Anthropic’s rapid rise in the AI landscape is attributed to its innovative models, particularly the Claude family, which has achieved an incredible 1,000% year-over-year growth, pushing its annual recurring revenue to $3 billion.
According to Menlo Ventures, the competitive landscape shows Anthropic leading with 32%, followed by OpenAI at 25%, Google at 20%, and Meta’s Llama at 9%. DeepSeek trails with a mere 1%. This data highlights a dramatic shift in enterprise preferences towards Anthropic’s offerings.
What’s fueling Anthropic’s success? The first factor is its dominance in code generation, termed “AI’s first killer app.” Anthropic’s models have captured 42% of the programming market, doubling OpenAI’s 21%. Notably, Claude has transformed platforms like GitHub Copilot into a thriving $1.9 billion ecosystem, showcasing the real-world impact of its technology.
Another key driver is Anthropic’s use of reinforcement learning with verifiable rewards (RLVR). This method allows for precise feedback, enhancing the model’s ability to produce accurate results. By leveraging this approach, Anthropic has enabled its LLMs to solve problems more efficiently and integrate seamlessly with external tools, enhancing usability for developers.
As enterprises shift their focus from just building AI to implementing it in production, the demand for high-performing models has surged. The Menlo Ventures study indicates that 74% of startups now report most of their workloads are in production, indicating a significant industry trend. Large enterprises are catching up, with 49% confirming similar usage levels.
The landscape for open-source LLMs is also evolving. Their usage has plummeted to 13% from 19% just six months ago, as performance continues to lag behind proprietary models. Despite the emergence of new models from companies like DeepSeek and Alibaba, their traction remains limited compared to the dominant players.
In a time when AI advancements are reshaping business strategies, the question arises: what will the future hold for AI models? While predictions are notoriously difficult, the conditions are ripe for a new generation of AI enterprises. As Menlo Ventures stated, “The market changes by the week, with exciting new model launches and plunging costs.”
Stay tuned for more updates on this rapidly evolving landscape, as the competition heats up among AI giants like Anthropic, OpenAI, Google, and Meta. The implications for businesses and developers are profound, making this a pivotal moment in the AI sector.
