OpenAI has allocated a stock grant pool worth 10% of the company, valued at $500 billion in October. The company has already issued $80 billion in equity, totaling about 26% of its ownership. It is also exploring fundraising at a new valuation of approximately $750 billion.

OpenAI has allowed current and former employees to donate their equity to charity after years of frustration over restrictions. This change comes as the company's share price rises significantly, but employees face a tight deadline to decide on their donations. Concerns remain about OpenAI's control over employee equity amid its recent restructuring.
