Rizvi Traverse Management said in its filing that it had already distributed its shares to the underlying investors. They included many Rizvi-controlled firms, JPMorgan Chase & Co. (NYSE:JPM), and Kingdom Holding, which is owned by Prince Alwaleed bin Talal of Saudi Arabia. The American banking giant and Rizvi had previously signaled that they won’t unload their stakes. But some of the recipients might have chosen to cash out.
