A leaked cap table reveals the governance structure that sits underneath one of the most extraordinary wealth transfers in technology history. Microsoft invested $13 billion and holds a stake now worth $228.3 billion, an unrealized gain of $215.3 billion. The OpenAI Foundation holds 25.8 percent of the company, worth $219.8 billion, and controls 100 percent of board appointments, Forbes reported. Sam Altman, the CEO, holds zero equity.
That structure is now the central exhibit in a fraud trial scheduled to begin April 27 in Oakland, California.
Elon Musk's lawsuit, which Inc.com first reported, centers on his $38 million donation to the OpenAI Foundation, which he says was contingent on the organization maintaining its nonprofit status. He is seeking $79 billion to $139 billion in damages. The cap table makes the governance paradox legible: a nonprofit foundation controls the board of the world's most valuable private company, while Microsoft, the largest economic shareholder, has no board appointment rights and Sam Altman, the CEO, holds zero equity.
That architecture is what the April 27 trial will interrogate.
The cap table was reconstructed from public filings and posted to X by investor and writer Sheel Mohnot in early April. It shows a company that has distributed enormous wealth to investors while leaving control with the entity that started it: a San Francisco nonprofit founded in 2015.
The spread of outcomes among investors is wide. SoftBank, which has committed $64.6 billion to OpenAI, holds an 11.66 percent stake now valued at $99.3 billion, an unrealized gain of roughly $50 billion. Khosla Ventures invested $50 million and holds a stake worth $1.5 billion, a 30-times return. Thrive Capital, led by Josh Kushner, invested approximately $3.5 billion and holds a 1.98 percent stake valued at $16.9 billion, a 4.8-times multiple, Forbes reported. NVIDIA holds 3.47 percent, a stake estimated at $29.6 billion against a cost basis of $30.1 billion, roughly break-even on the investment. Sound Ventures, Kutcher's firm, shows an estimated $1.3 billion in current value against a cost basis of roughly $20 million to $30 million in early rounds, a multiple of approximately 43 times. Kutcher himself holds a 30 percent carried interest in Sound Ventures, a stake now worth roughly $400 million, Inc.com reported.
The cap table shows the distribution of economic interest. What it also shows, by design, is that economic interest and control are not the same thing at OpenAI.
The governance arrangement was not accidental. OpenAI transitioned from a nonprofit company to a capped-profit model in 2019 and then to a public benefit corporation in 2025, Inc.com noted. The structural logic of those transitions was to attract capital while preserving a mechanism for the nonprofit to retain ultimate control. That mechanism is the board appointment right now held exclusively by the OpenAI Foundation.
The trial in Oakland will test whether that arrangement honored the terms of the original charitable purpose. Musk's legal team has framed it as a breach of commitment. OpenAI has contested the claims. The cap table, in making the structure visible, is the filing that both sides will cite most.
The timing matters because OpenAI is targeting an IPO in 2026 or 2027 at a potential $1 trillion valuation, according to Forbes. The governance structure that survives a private company does not automatically survive a public listing. Whoever controls the board at the point of IPO will control the company's direction through one of the largest technology offerings in history. The trial concludes before that window opens. The question it answers will shape what comes next.
