OpenAI Narrows Anthropic’s Enterprise Lead

Enterprise AI is behaving more like a liquid software budget than a locked-in platform, making model quality and release cadence powerful switching triggers.

• –Ramp’s data is a useful signal, but it skews toward smaller and technology-focused businesses and excludes much of the largest-enterprise market.
• –Anthropic still leads current tracked spend; OpenAI’s faster growth does not yet equal a market-share takeover.
• –New model releases can rapidly redirect workloads, weakening claims that enterprise integrations alone create durable vendor lock-in.
• –Developers should maintain model evaluations, routing layers, and fallback providers while pricing and capabilities continue to churn.
