Microsoft became the first company after Apple to reach a $1 trillion market capitalization in 2019.
Microsoft crossed the $1 trillion mark during trading on April 25, 2019, following the release of strong quarterly results. Its valuation was supported by growing cloud-computing revenue, especially from Microsoft Azure, as well as Office subscriptions, Windows, enterprise software, and gaming.
The milestone showed how Microsoft had changed from being known primarily for boxed PC software into a broad technology company with major recurring cloud and services income.
Microsoft had briefly reached the $1 trillion level earlier in 2019 but did not remain above it. Market-cap milestones can therefore be reported as intraday crossings or end-of-day valuations, and those descriptions are not always identical.
