Cost of Monopoly: OpenAI Co-Founder Greg Brockman Discloses $30B Stake

The transparency of the financial structure of AI market leaders is raising questions. On May 5, 2026, during court proceedings, OpenAI co-founder Greg Brockman officially disclosed the size of his stake, estimated at nearly $30 billion.

The plot takes on a special piquancy against the backdrop of yesterday's insider reports from The Wall Street Journal that OpenAI is systematically missing its KPIs for revenue and user growth ahead of its IPO. The documents also shed light on the complex system of financial ties between Brockman and Sam Altman. The unprecedented concentration of personal wealth in the hands of management—whose product burns billions renting Azure servers and infrastructure—is a classic symptom of venture capital overheating. Regulators and investors are getting a clear signal: corporate governance in AI giants still remains opaque.
