Amazon's market value topped $3 trillion for the first time Monday, propelled by a sharp rally following strong second-quarter earnings that showed the AI boom is driving fresh demand for its cloud-computing business — the company's main profit engine.
The Numbers
Amazon shares were last up 5% at $285.01, hitting a record high and marking the stock's best single session since May 5. Shares have gained more than 23% so far this year. Last week, the stock recorded its biggest one-day jump since April 2012 after Amazon delivered its strongest cloud growth in more than four years and raised its annual capital spending forecast.
What Drove the Rally
Amazon Web Services posted $42.2 billion in revenue for the quarter, with operating margins of 39% — a figure that stands in sharp contrast to the company's traditionally thin-margin e-commerce business. CEO Andy Jassy responded to surging demand by raising full-year 2026 capital expenditure guidance from $200 billion to $220 billion, driven partly by rising memory chip prices tied to the broader AI buildout. "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," Jassy said. "In fact, the demand we already have for 2028 is striking."
Joining an Exclusive Club
Amazon becomes the fifth company ever to reach a $3 trillion valuation, joining Apple, Microsoft, Alphabet, and Nvidia — with Nvidia currently the world's largest company at a market cap approaching $5 trillion, a figure Apple also crossed the same week. It took Amazon, founded by Jeff Bezos in 1994, just over two years to add a full trillion dollars in market value after first hitting $2 trillion in June 2024.
A Notable Divide Among the "Magnificent Seven"
Amazon and Microsoft stand out as the only two members of the so-called Magnificent Seven whose AI spending has clearly paid off in investors' eyes this earnings season. Tesla, Alphabet, and Meta all saw their hefty AI spending plans weigh on free cash flow in the prior quarter, drawing more skepticism from markets even as they too continue investing heavily in infrastructure.
What's Fueling AWS's Growth
AWS has benefited from expanding partnerships, including cloud infrastructure and chip supply deals with OpenAI, Anthropic, and Meta, among others. The unit's Project Rainier buildout for Anthropic has continued ramping up, adding to the demand picture that's driven Amazon's custom AI chip and cloud businesses to record growth.
The Broader Market Reaction
Other major tech stocks moved higher alongside Amazon on Monday, with Microsoft adding 4%, Meta Platforms jumping 6%, and Alphabet gaining 3.6% — reflecting broader investor optimism that corporate AI spending is beginning to translate into tangible revenue growth, even amid ongoing investor jitters tied to the Iran war and inflation.
What's Next
With Jassy signaling that demand visibility already extends into 2028 and capital spending continuing to climb, investors will be watching closely whether AWS can sustain this pace of growth in the coming quarters — and whether Amazon's $3 trillion milestone marks a durable re-rating or simply the latest peak in an increasingly AI-driven market cycle.
