Oracle is working with some of ByteDance's investors, including General Atlantic and Sequoia Capital, on making an offer for the TikTok assets that would challenge a rival bid from Microsoft Corp, the sources said, speaking on condition of anonymity.
ByteDance, TikTok, Oracle, General Atlantic and Sequoia declined to comment. The Financial Times first reported Oracle's interest in TikTok.
Oracle shares were trading up 3.4 per cent on the news on Tuesday morning, giving the company a market capitalization of $171 billion.Twitter Inc has also approached ByteDance to express interest in acquiring the US operations of TikTok, though its chances are seen as remote because of its smaller size and the antitrust scrutiny for such a combination, sources said earlier this month.
