Microsoft, founded in 1975, is headquartered in Redmond, Washington, and became a trillion-dollar public company in 2019.
Microsoft crossed a $1 trillion market capitalization during trading on April 25, 2019. Its share-price growth was supported by expanding cloud-computing operations, especially Azure, alongside established businesses such as Windows, Office, and enterprise software.
Bill Gates and Paul Allen founded Microsoft in Albuquerque, New Mexico, after developing a version of the BASIC programming language for the Altair 8800 microcomputer. The company moved its headquarters to the Seattle region and became one of the most influential personal-computing businesses in history.
Microsoft’s valuation milestone was not the same as becoming the world’s first trillion-dollar company: Apple reached that mark in 2018. Microsoft later became one of the companies to pass $2 trillion and $3 trillion at different points. Its market capitalization changes daily because it depends on the market price of its outstanding shares.
