OpenAI's Internal Memo: 'Claude Has Become a Religion'
A leaked OpenAI memo targets Anthropic's enterprise surge, blaming Microsoft for blocking AWS Bedrock access.
An internal OpenAI memo — reportedly from its Chief Revenue Officer — has surfaced, and it reads like a company on defense. The memo calls Claude adoption a "religion-level mania" and frames Anthropic's strategy as one built on "fear, restriction, and elite control" of AI.
But the sharper admission is structural: OpenAI says Microsoft has limited its ability to reach enterprise customers where they live — specifically on AWS Bedrock, where Anthropic has quietly dominated. The numbers back the panic: as of early 2026, 65% of enterprises procuring new AI services chose Anthropic; only 32% picked OpenAI. Anthropic now has 1,000+ clients spending $1M+ annually.
On compute, OpenAI claims the upper hand — projecting 30 GW by 2030 vs. Anthropic's estimated 7–8 GW by end of 2027 — calling it a "strategic misstep" by Anthropic.
Why it matters: when the market leader starts writing memos about a competitor being a 'religion,' the competitive landscape has already shifted.
