The Supreme Court could rule on TikTok’s fate as soon as Wednesday, after justices signaled during oral arguments Friday they may uphold the federal law banning TikTok unless it divests itself from ByteDance, expressing skepticism of TikTok’s opposition to the policy.

ByteDance, TikTok’s parent company, said it will start the shutdown process if the Supreme Court doesn’t step in.

The Supreme Court is set to rule on TikTok’s future in the U.S., as a potential ban or forced sale approaches.
