OpenAI buys back $7 bn in employee stock at $852 bn valuation

OpenAI has completed a roughly $7 billion secondary share sale that allowed current and former employees to sell shares at an $852 billion valuation. The deal gave employees a chance to monetise a part of their stakes before the company's highly anticipated IPO. The tender offer had been in the works since OpenAI closed a $122-billion funding round in March.
