OpenAI’s enterprise market share has declined from 50% to 25% as Anthropic gains ground. According to Menlo Ventures’ mid-2025 analysis, Anthropic now commands 32% of enterprise LLM utilization while OpenAI has fallen to 25%.
Anthropic’s clarity: “We’re an enterprise AI company”—one sentence that clarifies everything. Every product decision, every hire, every partnership flows from that single strategic choice.
OpenAI’s sprawl: The advertising push signals “consumer company” to enterprise buyers. The multi-product expansion dilutes engineering focus. The safety narrative—once a differentiator—now belongs more credibly to Anthropic.
