NoteThe source text explicitly states in the 'LLM Market Share' section: 'We estimate Anthropic now earns 40% of enterprise LLM spend... OpenAI lost nearly half of its enterprise share, falling to 27% from 50% in 2023. Google also saw significant gains, increasing its enterprise share from 7% in 2023 to 21% in 2025.' This directly confirms the claim's exact values (OpenAI 27%, Anthropic 40%, Google 21%) for the same time period (December 2025) and same metric (enterprise LLM API market share per Menlo Ventures report).
