Microsoft Corp. briefly achieved a historic $3 trillion market valuation on Wednesday, in the latest example of how optimism over artificial intelligence has fueled a seemingly unstoppable advance in the software giant.

The stock rose as much as 1.7% to $405.63, taking its market capitalization just over $3 trillion during market hours. However, it closed up just 0.9%, ending at a record but with a valuation of $2.99 trillion.
