Headline: Anthropic Surpasses OpenAI in Enterprise AI Subscriptions Amid Government Scrutiny

Anthropic's enterprise AI subscription market share reached 41% in May 2026, surpassing OpenAI's 39.5% for the first time, according to data from enterprise spending platform Ramp. This market shift occurred as the U.S. Commerce Department on June 12, 2026, mandated Anthropic remove its Mythos 5 and Fable 5 models, citing export controls. Ramp Chief Economist Ara Kharazian noted that government scrutiny, including a March 2026 Pentagon designation as a "supply chain risk" for refusing certain AI applications, has paradoxically enhanced Anthropic's enterprise appeal. The company's Claude Code and Claude Opus series are key drivers for enterprise adoption, limiting the impact of recent model removals on current revenue. Anthropic recently secured $65 billion in funding in May 2026, valuing it at $965 billion, and has reportedly filed for an IPO.
