The claim states OpenAI has 50% market share with an expected value of 50%, but the source explicitly states this was true 'by the end of 2023' and has since 'eroded' to 25% as of the 2025 mid-year update. The 50% figure is outdated information from approximately 1.5 years prior to the source document's publication date of July 31, 2025.
