NoteThe source text directly confirms all key fields in the record: (1) name 'Series E' is implicit in the context of a major funding round; (2) raised amount of $6.6 billion is explicitly stated ('raised $6.6 billion'); (3) valuation of $157 billion is explicitly stated ('values OpenAI at $157 billion post-money'); (4) the date cannot be directly verified from the source text itself, which does not include a publication date in the excerpt provided, but the article references recent events (CTO resignations in 'late September', co-founder John Schulman announcement 'in August') and describes the announcement as happening 'today', suggesting this is a contemporary news article. The exact date of 2024-10-02 is unverifiable from the source text alone, but the three numeric/categorical fields are all confirmed.
