Oracle has reportedly surpassed Microsoft to manage TikTok's US operations, pending US government approval. Microsoft is no longer a contender, as confirmed by TikTok's parent company, ByteDance. President Trump has threatened to ban TikTok unless it sells its US business, citing security concerns over its Chinese ownership. TikTok denies sharing data with the Chinese government and is suing the Trump administration to prevent the ban.
