OpenAI has completed a $7 billion employee stock buyback, according to reports. The transaction comes as the company prepares for potential next steps related to an initial public offering.

Quartz reports the buyback is part of a process that follows OpenAI’s confidential IPO filing with the U.S. Securities and Exchange Commission in June. Yahoo Finance similarly says the buyback concludes ahead of a possible IPO, citing the same broader timeline.

Both outlets also describe the related implications for OpenAI’s valuation, stating the deal values the company at about $852 billion. While the reports align on the size of the buyback, the timing, and the valuation figure, they differ mainly in emphasis—Quartz highlights the valuation and the SEC filing, while Yahoo Finance focuses more directly on the completion of the buyback in anticipation of potential IPO activity.
