Apple is increasing its domestic investment by an additional$100 billion, bringing its total commitment to US manufacturing to$600 billion over the next four years.

The announcement was made by CEO Tim Cook during a joint appearance with President Donald Trump at the White House, as the administration signals plans to impose steep tariffs on foreign-made semiconductors.

The investment includes a new American Manufacturing Program aimed at expanding US production of key Apple components, such as AI servers and rare earth magnets. Facilities are already under development in states including Texas, Kentucky, and Arizona.

Apple says the initiative will support 450,000 jobs across all 50 states and reduce reliance on overseas supply chains.

Apple's expanded spending arrives amid criticism of its slow progress in AI. With its 'Apple Intelligence' software struggling for traction, and the recent departure of foundation model head Rouming Pang to Meta, the company is now shifting focus.

Cook confirmed that investment in AI infrastructure is accelerating, with data centres expanding in five states.

While Apple's move has drawn praise for supporting American jobs, it has also stirred controversy. Some users expressed discontent with Cook's public alignment with Trump, despite the strategic importance of avoiding tariffs.

Trump stated that companies investing in the US would not face the proposed import charges.
