Apple is poised to announce a fresh $100 billion commitment to U.S. manufacturing, the White House said on Wednesday. President Donald Trump is expected to outline the pledge later today at the White House alongside Apple Chief Executive Officer Tim Cook as part of a new domestic manufacturing program. The additional spending would raise Apple’s planned investment in the United States to roughly $600 billion over the next four years, expanding on the $500 billion package the company unveiled in February. The new funds are expected to finance further factory capacity and supplier initiatives intended to anchor more of Apple’s supply chain onshore. White House economic adviser Kevin Hassett signaled the move earlier in a Fox Business interview, saying the administration was "likely to hear about a new factory from Apple" and an investment commitment today. Apple shares rose as much as 3.6% in pre-market New York trading following his remarks. Bringing production stateside could help the iPhone maker blunt the impact of threatened tariffs of at least 25% on handsets assembled abroad. The White House framed the announcement as a win for its "America First" agenda, saying the expanded effort will bolster U.S. jobs and strengthen economic and national security.
