Microsoft Market Value Surges by Record-Breaking $450 Billion
Microsoft's market value surged by about $450 billion on July 30, making it the largest one-day gain in the company's history. This surpassed Nvidia's previous record of $441 billion set on April 9, 2025.
The stock price rose by 15.5% to $451.10 after Microsoft reported an 18% revenue growth and guided its Azure cloud platform to grow about 45% in constant currency during the fiscal first quarter.
Despite this significant increase, shares of Microsoft still trade around 12% below their 52-week high of $553.72.
A study of six other companies that experienced similar market value gains since February 2022 found that only three performed well in the following quarters. The key factor was whether the growth that caused the pop continued to show up.
