OpenAIのテンダー売却でマルチミリオネアが75人誕生

following a $6.6 billion secondary tender offer in october 2025, openai employees liquidated equity holdings in a transaction that valued the company at $852 billion. to accommodate strong investor demand, the company tripled the liquidation cap from $10 million to $30 million, enabling roughly 75 staff members to cash out with eight-figure sums. this event marked the first opportunity for many employees to sell shares they held for at least two years, with early stakeholders witnessing returns exceeding 100x. the sale underscores openai's massive financial growth, recently highlighted by a funding round that raised $122 billion and granted president greg brockman a stake worth roughly $30 billion.
