Microsoft first surpassed a $1 trillion market capitalization among software companies in 2019.
Microsoft crossed the $1 trillion threshold during trading on April 25, 2019, after reporting strong quarterly results. Its valuation reflected the expansion of cloud computing, especially Azure, alongside established businesses such as Windows, Office, and enterprise software.
The company had transformed from a primarily personal-computer software business into a broad technology platform. Subscription products, cloud infrastructure, professional networking through LinkedIn, and gaming all contributed to the market’s view of Microsoft’s future growth.
Microsoft had already briefly passed $1 trillion during intraday trading in 2019, but market-cap claims can specify either an intraday crossing or a closing valuation. The exact ranking also depends on whether the comparison includes all technology companies or software companies specifically.
