Why it matters
This revelation quantifies Microsoft's massive financial leverage over the leading AI lab, potentially triggering fresh antitrust scrutiny and changing how AI startups structure corporate partnerships.
Key points
- Leaked documents suggest Microsoft's total investment is now valued at approximately $234 billion in equivalent equity.
- The data reveals a complex 'waterfall' structure where Microsoft captures a significant percentage of profits until its cap is reached.
- Early employee equity packages are shown to be significantly larger than those at rival labs like Anthropic or Google DeepMind.
- The leak coincides with increased pressure from the FTC and European Commission regarding the competitive nature of the partnership.
The story
A leaked capitalization table for OpenAI has reportedly surfaced, detailing the financial intricacies of Microsoft's multi-year investment strategy. The documents suggest that Microsoft has realized an 18x return on its cumulative capital infusions, a figure that significantly exceeds previous public market estimates. This disclosure comes at a sensitive time for the organization, as global antitrust regulators in the EU and US are currently investigating whether the partnership constitutes a de facto merger. The cap table also provides transparency into the distribution of equity among early employees and venture capital firms, highlighting the aggressive valuation trajectory of the San Francisco-based entity since its transition to a capped-profit model.
Who's involved
