NEW YORK — Microsoft is in advanced talks to buy the US operations of TikTok, the popular Chinese-owned video app that has been a source of national security and censorship concerns, according to a person familiar with the discussions who spoke only on condition of anonymity because of the sensitivity to the negotiations.
The potential deal would be a victory for both companies, making Microsoft Corp. a major player in the social media arena and providing relief to TikTok and its parent company, Bytedance Ltd., a target of President Trump’s.
Trump said Friday that he would take action as soon as Saturday to ban TikTok in the United States. Trump’s comments on Friday aboard Air Force One came after published reports that the administration is planning to order China’s ByteDance to sell TikTok.
“As far as TikTok is concerned, we’re banning them from the United States,” Trump told reporters Friday on Air Force One as he returned from Florida.
Trump said he could use emergency economic powers or an executive order to enforce the action, insisting, “I have that authority.” He added, ‘‘It’s going to be signed tomorrow.”
Microsoft declined to comment.
Reports by Bloomberg News and the Wall Street Journal citing anonymous sources said the administration could soon announce a decision ordering ByteDance to divest its ownership in TikTok.
There have been reports of US tech giants and financial firms being interested in buying or investing in TikTok as the Trump administration sets its sights on the app. The New York Times and Fox Business, citing an unidentified source, first reported Friday that Microsoft is in talks to buy TikTok.
On Saturday it posted a short video from its US general manager Vanessa Pappas saying that “We’re not planning on going anywhere.”
ByteDance launched TikTok in 2017, then bought Musical.ly, a video service popular with teens in the United States and Europe, and combined the two. A twin service, Douyin, is available for Chinese users.
TikTok’s fun, goofy videos and ease of use has made it immensely popular, and US tech giants like Facebook and Snapchat see it as a competitive threat. It has said it has tens of millions of US users and hundreds of millions globally.
But its Chinese ownership has raised concerns about the censorship of videos, including those critical of the Chinese government, and the potential for sharing user data with Chinese officials.
TikTok maintains it doesn’t censor videos based on topics sensitive to China and it would not give the Chinese government access to US user data even if asked. The company has hired a US chief executive, a former top Disney executive, in an attempt to distance itself from its Chinese ownership.
US national security officials have been reviewing the Musical.ly acquisition in recent months, while the armed forces have banned their employees from installing TikTok on government-issued phones. Secretary of State Mike Pompeo said this month that the United States was considering banning TikTok.
These national security worries parallel a broader US security crackdown on Chinese companies, including telecom providers Huawei and ZTE. The Trump administration has ordered that the United States stop funding equipment from those providers in US networks. It has also tried to steer allies away from Huawei because of worries about the Chinese government’s access to data, which the company has denied it has.
The Trump administration has stepped in before to block or dissolve deals on national security concerns, including stopping Singapore’s Broadcom from its $117 billion bid for US chipmaker Qualcomm in 2018 in an effort to help retain US leadership in the telecom space.
Other countries are also taking action against TikTok. India this month banned dozens of Chinese apps, including TikTok, citing privacy concerns, amid tensions between the countries.
Microsoft, which owns LinkedIn, is the number four digital ad company in the United States after Google, Facebook, and Amazon. Still, buying TikTok would be a significant change of direction from Microsoft chief executive’s Satya Nadella’s focus on workplace software.
Unlike Google or Facebook, which dominate the digital advertising industry, Microsoft hasn’t been under the intense scrutiny of US politicians and antitrust regulators lately over its market power. Moorhead said that might make it easier to swoop in and acquire TikTok, which poses a competitive threat to social networks like Facebook, Instagram, Google’s YouTube and Snapchat. It’s an interesting irony that it was Microsoft at the center of the landmark antitrust case 20 years ago.
