A non-profit parent entity with a wholly owned for-profit subsidiary (actually, the non-profit wholly owns and controls a third "manager" entity which in turn is the controlling but not majority shareholder of the for-profit subsidiary) where the profit of the for-profit entity is "capped" and oh by the way, that for-profit subsidiary has a 49% shareholder who happens to be Microsoft is a Rube Goldberg contraption.
The above is just scratching the surface of the absurdity that is the OpenAI corporate structure. Microsoft despite having 49% ownership of the for-profit subsidiary gets 75% of their profit..........until their initial investment is recouped. Employees get Profit Participation Units (PPUs) which are NOT equity but which entitle employees to a percentage of profits, again up to the "cap". I have a hunch that when they say Sam and the Board have no "equity" they mean that they have no traditional equity in the form of RSUs or options, but instead have a similar PPU arrangement. Then of course, when OpenAI achieves AGI, whatever the hell that is is, then everything from that point forward reverts back to the non-profit entity and Microsoft, other investors, and employees get hosed.
They planted the seeds of their own destruction by ousting the CEO and causing the Chairman to quit shortly thereafter. Lawyers for Microsoft and other investors will be knocking on the boards' door Monday morning and some of these board members who have never had a real job in their lives will get steamrolled.
