Microsoft and Amazon both saw their stocks surge again Monday, riding a post-earnings tech wave across the stock market that pushed Amazon past $3 trillion in value for the first time.
The gains follow earnings reports last week in which both companies’ cloud platforms exceeded expectations. Microsoft said Azure grew 43%, passing $100 billion in annual revenue for the first time. Amazon said AWS grew 37%, its fastest pace in 18 quarters.
Microsoft and Amazon are now the world’s fourth and fifth most valuable companies, respectively. The three ahead of them (Nvidia, Alphabet and Apple) are all headquartered in the Bay Area, although each has sizeable engineering centers in the Seattle region.
Amazon rose 4.6% in intraday trading to $284.15 as of publication time, after touching an all-time high of $287.20 earlier in the session, giving it a market value of $3.06 trillion.
Microsoft climbed 5.2% to $488.97, worth $3.63 trillion. Its rally began Thursday, when it added nearly $450 billion in market value, the largest one-day gain by any company on record.
The rallies came despite AI spending plans that have unsettled investors for much of the year. Microsoft went into earnings near a one-year low, after a $357 billion wipeout to start the year.
It’s all still coming at a huge cost. Microsoft spent a record $41 billion on capital projects last quarter and told investors to expect more than $50 billion in the current quarter. Amazon raised its 2026 forecast to about $220 billion from $200 billion, citing rising memory chip prices.
In one sign of the impact of the spending, Microsoft’s free cash flow fell 23% last quarter. Amazon’s free cash flow turned negative for the first time since 2023.
But cloud growth and other signs of demand for AI seem to have appeased investors for now.
Amazon CEO Andy Jassy told investors the spending reflects unmet demand: “Even at that amount, we will still not have enough capacity to meet all the demand we have in 2026, and I believe this dynamic will also be true in 2027 too. In fact, the demand we already have for 2028 is striking.”
The gains come as both companies operate with fewer people. Amazon confirmed 16,000 more corporate job cuts in January, bringing the total to 30,000 since October, along with more recent reductions in its robotics and artificial general intelligence groups.
Microsoft cut 4,800 jobs in July, revamping its salesforce and overhauling Xbox.
