Anthropic's AI models have become the top choice for enterprises, surpassing OpenAI in market share. The company's focus on coding and performance improvements has led to significant growth, particularly in the software development sector.

Anthropic's Rise to Dominance in Enterprise AI

In a significant shift within the AI industry, Anthropic has emerged as the leading provider of AI models for enterprises, surpassing its rival OpenAI. According to a report from Menlo Ventures, Anthropic now holds 32% of the enterprise large language model market share by usage, while OpenAI's share has declined to 25%

Coding Sector Leadership

Anthropic's dominance is particularly pronounced in the coding sector, where it commands an impressive 42% of the enterprise market share, more than double OpenAI's 21%

. This success in the coding domain has been a key driver of Anthropic's growth, with AI-assisted programming emerging as what Menlo Ventures calls "AI's first killer app"

Performance and Innovation

The company's rapid ascent is attributed to the strong performance of its Claude Sonnet and Claude Opus models. The release of Claude 3.5 Sonnet in June 2024 and Claude 3.7 Sonnet in February 2025 laid the foundation for Anthropic's surge in usage

Enterprise Preferences and Market Dynamics

Enterprises have shown a clear preference for closed models, with more than half of the surveyed companies reporting that they don't use open-source models at all

. This trend has led to a decline in open-source model usage, dropping from 19% to 13% of enterprise daily workloads in just six months

The market dynamics favor performance over price, with companies willing to pay for the newest and fastest models. As Matt Murphy from Menlo Ventures notes, "Even as individual models drop 10x in price, builders don't capture savings by using older models; they just move en masse to the best-performing one"

Anthropic's Business Growth and Challenges

Anthropic's success has translated into substantial financial growth. The company has reportedly seen its annual recurring revenue jump from $1 billion to $5 billion in just seven months

. However, this rapid growth comes with risks, as nearly half of Anthropic's $3.5 billion in API revenue stems from just two customers – coding assistant Cursor and Microsoft's GitHub Copilot

Competition and Future Outlook

While Anthropic currently leads the enterprise AI market, competition remains fierce. OpenAI is expected to launch GPT-5, which could challenge Claude's coding supremacy

. Google and Meta are also significant players, with Google holding 20% of the enterprise market share and Meta's Llama maintaining dominance in the open-source segment

Implications for the AI Industry

The shift in enterprise preferences towards Anthropic's models signals a maturing AI market where performance and specialized capabilities, particularly in coding, are becoming key differentiators. As companies increasingly move from building and training models to inference and production use, the competition among AI providers is likely to intensify, driving further innovation and specialization in the field

This evolving landscape presents both opportunities and challenges for AI companies and enterprises alike, as they navigate the rapidly changing terrain of artificial intelligence technologies and their applications in business contexts.
