Apple will announce a domestic manufacturing pledge of $100 billion on Wednesday that will focus on bringing more manufacturing to the United States, a White House official said.

U.S.-listed shares of the company rose 3% in Wednesday trading.

The pledge would be a new financial commitment on top of what Apple has already pledged, the official said on customary condition of anonymity.

Apple said in February it would spend $500 billion in U.S. investments in the next four years that will include a giant factory in Texas for artificial intelligence servers while adding about 20,000 research and development jobs across the country.

Apple did not immediately respond to requests for comment.

Earlier, White House economic adviser Kevin Hassett said Apple Inc was likely to make an investment announcement on Wednesday, as he discussed the financial pledges made by companies and countries under President Donald Trump.

"They're moving here in droves. This is trillions and trillions of dollars of commitments for people to build new factories here. In fact, you're likely to see one today from Apple," Hassett said in an interview with Fox Business Network. He did not elaborate.
