Tracking OpenAI's sprawling network of deals has become a major challenge for investors. Morgan Stanley's analysts have released a detailed report attempting to map this complex ecosystem, revealing unprecedented capital intensity in the AI sector. The study, part of their 'Mapping the AI Ecosystem' series, highlights the sheer scale of OpenAI's financial engagements, which now involve billions in investments and memoranda. The report's centerpiece is a complex diagram illustrating these connections, though the analysts caution it's not a complete solution. This effort underscores the difficulty in monitoring the financial flows within what is arguably the most significant AI entity today.
