OpenAI is reportedly raising money at a $150 billion valuation — more than the market capitalization of over 88% of Fortune 500 firms, including Goldman Sachs, Uber, and BlackRock. The startup is in talks to raise $6.5 billion from various investors, Bloomberg reported on Thursday, citing people familiar with the matter. The valuation does not include the amount being invested. The new valuation makes the startup one of the most valuable in the world — and it's a big jump from the company's previous $86 billion valuation.
