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.

Justices did not issue a ruling in the closely watched case over a potential ban, dialing up intrigue over the app’s fate.

TikTok is preparing to go dark for U.S. users this Sunday if the Supreme Court does not grant it emergency appeal to halt a law that would ban the app unless parent ByteDance divests its stake in TikTok,
