Funding Round: Series F (OpenAI)

NoteThe source confirms all three key numeric fields: (1) raised amount of $40 billion is explicitly stated multiple times ('$40 billion funding round', '$40 billion financing'); (2) valuation of $300 billion is confirmed ('values the ChatGPT maker at $300 billion'); (3) the date cannot be precisely verified from the source text alone, as it only says 'Monday' without specifying which Monday or providing a full date. However, the article references current events (Trump announcement in January, SoftBank disclosure on Monday) consistent with early 2025. The exact date of 2025-03-31 is unverifiable from this source, but the other fields are directly confirmed. Since the name 'Series F' is not explicitly stated in the source (the source refers to it as 'funding round' or '$40 billion round'), this is a minor gap, but the round itself is clearly identified and the numeric values match exactly.
