As the artificial intelligence (AI) revolution enters its third year, certain Wall Street analysts expect Nvidia (NASDAQ: NVDA) and Microsoft (NASDAQ: MSFT) to make history by becoming the first $4 trillion companies.

Tesla, IBM and Meta Platforms helped lead most US stocks higher on Thursday following a rush of profit reports from some of the country’s most influential companies. The S&P 500 rose 0.5%, as four out of every five stocks in the index climbed.

Stocks gave up earlier gains Friday as the White House reaffirmed President Donald Trump’s plan to implement some of his long-promised tariffs Saturday, with the market closing out a whirlwind week highlighted by Nvidia’s record-breaking losses in reaction to China’s DeepSeek cheaper AI model and a flurry of earnings reports.
