NoteThe source directly confirms the claim. The Menlo Ventures 2025 Mid-Year LLM Market Update explicitly states: 'By the end of 2023, OpenAI commanded 50% of the enterprise LLM market.' This matches the claim's exact value (50%) and time period (2023-12, i.e., end of 2023). The source is from a 2025 report discussing historical market share data from 2023, which is appropriate for verifying a claim marked 'as of 2023-12'.
