A new U.S.-controlled company is taking over TikTok’s American business after Donald Trump signed an executive order Thursday approving the deal. The takeover, led by Oracle, gives a group of American and international investors a 45% stake in the video app. ByteDance, the China-based owner of TikTok, will hold less than 20%, avoiding a full ban under a U.S. national security law that forces foreign tech companies to divest their U.S. holdings or face shutdown.
