Amazon surpassed a $3 trillion market capitalization for the first time after its shares climbed nearly 5% to a record high, making it only the fifth publicly traded company to reach the milestone. The rally followed stronger-than-expected second-quarter earnings, with investors responding positively to accelerating growth in Amazon Web Services (AWS) and improved confidence in the company's long-term investment strategy.
The latest surge also made Amazon one of Wall Street's best-performing mega-cap technology stocks this year, with its shares up more than 23% since the beginning of 2026.
The biggest driver behind Amazon's rally was the performance of AWS, which reported its fastest revenue growth since 2021. The cloud computing division generated $42.2 billion in quarterly revenue, exceeding analysts' expectations and reinforcing its position as Amazon's primary profit engine.
The company also raised its annual capital expenditure outlook, signaling continued investment in expanding cloud infrastructure and advanced computing capabilities. Investors viewed the results as evidence that Amazon's spending is translating into stronger business performance rather than weighing on profitability.
"Amazon is probably the most emblematic of the economy right now. It's a consumer story and it's an AI story," said Mark Hackett, chief market strategist at Nationwide. "The big scepticism coming into earnings season was if they (hyperscalers) were turning the spigot down on spending on AI. We did not get that from Amazon and Microsoft and that has unleashed a much broader all-clear for the market," Hackett added.
Amazon's earnings helped lift sentiment across the broader technology sector, with shares of Microsoft, Meta, Alphabet, and Oracle also posting gains. The rally also reflected a shift in how investors evaluate the "Magnificent Seven" technology stocks, with companies increasingly being judged on individual financial performance instead of being viewed as a single group.
Giovanni Mazzariello, equity specialist at UniCredit, described last week's results from Amazon and other AI "hyper scalers" as "broadly reassuring."
"Taken together, rapid revenue growth, widening margins and a swelling backlog from all four hyperscalers, provide the clearest evidence that utilization and monetization are rising fast enough to absorb the growing depreciation and operating costs of the infrastructure build-out," Mazzariello said.

The $3 trillion milestone came just over two years after Amazon first crossed the $2 trillion valuation mark, underscoring the company's rapid growth. However, investors are also watching fresh developments after regulatory filings revealed that founder Jeff Bezos plans to sell up to 15 million Amazon shares under a pre-arranged trading plan.
Although the announcement caused a slight decline during after-hours trading, analysts believe that the prospects of Amazon look promising due to positive trends in AWS, more enterprise deals and increasing demands on cloud computing services. Looking ahead, investors will pay attention to future financial performance, capital expenditures and growth of the company.
