U.S. President Donald Trump and Apple CEO Tim Cook shake hands on the day they present Apple’s announcement of a $100 billion investment in U.S. manufacturing, in the Oval Office at the White House in Washington, D.C., U.S., August 6, 2025.

Apple shares rose 13% this week, its largest weekly gain in more than five years, after CEO Tim Cook appeared with President Donald Trump in the White House on Wednesday.
Shares of the iPhone maker rose 4% to close at $229.35 per share on Friday for the company’s largest weekly gain since July 2020. The week’s move added over $400 billion to Apple’s market cap, which now sits at $3.4 trillion.
Apple is the third-most valuable company, behind Nvidia and Microsoft and ahead of Alphabet and Amazon.
At the White House on Wednesday, Cook appeared with Trump to announce Apple’s plans to spend $100 billion on American companies and American parts over the next four years.
Apple’s plans to buy more American chips pleased Trump, who said during the public meeting that because the company was building in the U.S., it would be exempt from future tariffs that could double the price of imported chips.
Investors had worried that some of Trump’s tariffs could substantially hurt Apple’s profitability. Apple warned in July that it expected over $1 billion in tariff costs in the current quarter, assuming no changes.
“Apple and Tim Cook delivered a masterclass in managing uncertainty after months and months of overhang relative to the potential challenges the company could face from tariffs,” JP Morgan analyst Samik Chatterjee wrote on Wednesday. He has an overweight rating on Apple’s stock.
Cook’s successful White House meeting also comes two weeks after Apple reported June quarter earnings in which overall revenue jumped 10% and iPhone sales grew by 13%.
