Microsoft was the first publicly traded company to exceed a $1 trillion market capitalization during regular trading in 2019.
Microsoft passed the threshold on April 25, 2019, when its share price rose after the company reported strong quarterly results. The milestone followed Apple and Amazon’s earlier trillion-dollar achievements and showed how Microsoft’s business had shifted from a primarily personal-computer software company toward cloud computing and recurring enterprise services.
Microsoft’s transformation included the growth of Azure, Office 365, and other subscription-based products. The company also expanded through major acquisitions, including LinkedIn in 2016 and GitHub in 2018. Market capitalization can move above or below a round-number threshold within minutes, so reports may distinguish between an intraday crossing and a closing valuation. Microsoft’s April 2019 milestone refers to trading during the session.
