Twitter approached TikTok’s Chinese owner ByteDance to express interest in buying its US operations, according to the report.
Video-sharing platform TikTok has been at the heart of heated debate in recent weeks and takeover talks.
Last week, Donald Trump of America ordered companies to stop doing business with TikTok for 45 days over security concerns.
Tech giant Microsoft was the leader in the acquisition of TikTok but now Twitter has emerged as a leader.
But it is not clear whether Twitter can afford TikTok from Chinese owners and can finalize the deal within 45 days, according to sources cited in the Wall Street Journal.
The value of TikTok̵7;s operations in the US is unclear, but is estimated to be in the tens of billions of dollars.
Twitter’s market capitalization is around $ 29 billion (£ 22 billion), far behind Microsoft with over $ 1.6 billion.
But experts believe a probable deal with Twitter will face less legal scrutiny than Microsoft does.
A Twitter spokesperson declined to comment on a possible deal while TikTok did not immediately respond when contacted by the BBC.
Last Friday, Mr. Trump ordered US companies to stop doing business with Chinese apps within 45 days. The Trump administration claims that the Chinese government has access to user information collected by TikTok, which the company has always denied.
In response to the US President’s executive order, TikTok threatened legal action against the US and said they were “shocked” by the move.
The US government also announced a ban on Chinese-owned messaging app WeChat as tensions between the two countries escalated.
Last week, Mr. Trump said he would support Microsoft’s effort to buy back TikTok’s US operations if the government receives “a substantial share” of the proceeds.
He has set a deadline of September 15 for the deal to be finalized or the ban to be implemented.
Microsoft said it “will soon pursue discussions” for TikTok’s operations in the US, Australia, Canada and New Zealand.
Media expert Sharon Koh said: “Even if the deal is passed, whether Microsoft or Twitter hold a significant stake in TikTok, it remains to be seen how both sides will progress in terms of operations. “.
“It will take a chaotic effort for both organizations to overcome political sensitivities,” she added.
