[Trend to Watch] Claude Just Overtook ChatGPT in the Enterprise AI Race

A new study released by Menlo Ventures gives us a peek into the latest in AI model adoption within organizations.

Why you should care:
OpenAI's ChatGPT has been the clear leader in the AI space, dominating with over 75% traffic share vs competitors. While OpenAI has maintained its early market share, there's a new story coming to light within enterprise use.

This data shows a major disconnect:
Consumers love ChatGPT, but enterprises are choosing Claude.

What changed?
When corporate teams put AI into production, mistakes cost money and reputation. As a result, different factors drive their decisions.

The survey of 150+ enterprise technical leaders reveals how businesses are choosing AI when results matter.

Top 3 Takeaways on Enterprise AI Use

1. Anthropic overtook OpenAI as the AI enterprise leader

• Anthropic's Claude now has 32% enterprise market share vs ChatGPT's 25%
• Claude's growth is a big shift from 18 months ago (OpenAI held 50% share)
• What makes Claude stand out to enterprises?
  • Coding excellence: Claude captured 42% of the enterprise coding market share (vs OpenAI's 21%). Claude models have dominated as the top choice for developers over the past year, and they recently launched Claude Code - a dedicated coding interface that lets devs work with AI in their environment
  • Tool integration leadership: Claude's MCP (Model Context Protocol) and Connectors let it plug directly into the business tools you're already using - Notion, Asana, Stripe, Canva, Slack, and more. Instead of copying and pasting between apps, Claude can read from and write within your company tools and databases
  • Enterprise security focus: While other AI models operate like "black boxes" with unclear safety measures, Anthropic built Claude with transparent safety principles and enterprise-grade security controls
  • Agent training: Anthropic trained their models to be useful as agents, thinking step by step, reasoning through problems, and using external tools to deliver complex outputs

2. Performance > price

• Organizations are using top performing models over cheaper, faster ones
• 66% of companies upgraded to new models from their existing AI provider
• When new models are released, switching happens quickly (within weeks)
• It is rare for organizations to switch vendors (ex: ChatGPT to Claude), relationships are sticky once trust is established

3. Open-source AI stalls within enterprises

• Open-source models fell from 19% to 13% of enterprise workloads in 6 months
• What's causing this?
  • Meta's Llama leads open-source, but the Llama 4 launch underwhelmed. Other top open-source models are from Chinese companies that many enterprise are avoiding due to security concerns
  • Despite open-source offering cost savings and customization, they consistently trail frontier models like Claude and ChatGPT by 9-12 months in performance
  • Open-source requires technical deployment expertise that some enterprises don't want to manage

Looking Ahead

The AI market shifts fast, but today's pattern is clear. Anthropic is winning enterprise adoption because it is focusing on true business needs like coding, security, tool integration, and agentic abilities.

With OpenAI's ChatGPT-5 model release looming and continued Google AI features and model updates, the market could sizably shift again soon.

What is clear is that enterprises will prioritize the vendor that best meets their needs and not default to the same tool used by mass consumers.
