Microsoft on track for record one-day market value gain
Microsoft Corp. is poised to set the record for the largest single-day increase in market value ever for any stock. The Redmond, Washington-based company’s shares surged as much as 17% intraday. As of 12:55 p.m. in New York, its market capitalization had increased by $490 billion. If the gain holds through the close, it would surpass the previous record of a $440 billion one-day increase in market value set by Nvidia Corp., according to Bloomberg data, making it the biggest single-day market-cap gain in history. Nvidia’s record was set last year after U.S. President Donald Trump announced a 90-day pause on tariffs.
