US retail giant Walmart will team up with Microsoft to make a bid for the US operations of TikTok.
Walmart hopes the deal with a deal with the Chinese video-sharing app, in partnership with Microsoft, would help it expand its operations.
TikTok has been given 90 days to sell its US arm to an American firm or face a ban in the country.
Earlier on Thursday the firm’s boss resigned ahead of the impending ban by US President Donald Trump.
Microsoft confirmed at the beginning of August that it was in talks with TikTok. Now with Walmart it will go up against other prospective bidders, including the US tech giant Oracle.
Reports speculate that TikTok’s US operations could fetch between $20bn and $30bn if a deal is reached.
TikTok, which is owned by Chinese internet firm, ByteDance, has been accused of being a threat to US national security by the Trump administration.
TikTok and Beijing deny the US claims that the data the company collects from its users is at risk of exploitation by the Chinese government.
The founder of ByteDance, Zhang Yiming, has faced criticism for his decision to sell to a US company. But in a letter to his Chinese staff he said it was the only way to prevent the app from being taken down in America.
Chinese messaging app, WeChat, also faces a ban in the US.
