Microsoft has become only the second publicly traded company after Nvidia to surpass $4 trn (£3.03trn) in market valuation, after registering huge earnings.
On Thursday, shares rose on Wall Street with the S&P 500 and Nasdaq climbing to new record highs.
Stocks in Microsoft jumped after posting better-than-expected results, helped by its Azure cloud computing platform, which is a centrepiece of the company’s artificial intelligence (AI) efforts.
Nvidia tripled its value in just about a year and clinched the $4trn milestone before any other company on 9 July. Apple was last valued at $3.12trn.
