Amazon’s market value has climbed above the $3 trillion mark for the first time, becoming the fifth company to reach the milestone after strong quarterly results boosted confidence in its cloud computing and artificial intelligence businesses.
The company’s shares closed at a record high of $284.02 on Monday, rising 5% in New York trading. The stock has gained more than 23% since the beginning of the year, reflecting growing optimism about Amazon’s ability to benefit from rising demand for AI infrastructure.
Amazon joins Apple, Microsoft, Nvidia and Alphabet in the exclusive group of companies valued at more than $3 trillion. Nvidia remains the world’s most valuable listed company with a market capitalization of about $5 trillion, while Apple is valued at roughly $4.5 trillion and Microsoft at $3.6 trillion.
The rally gathered momentum after Amazon released second-quarter earnings last week that exceeded market expectations. Amazon Web Services (AWS), the company’s cloud computing division and its largest profit generator, reported net sales of $42.2 billion, up 36.7% from a year earlier. It marked AWS’s fastest growth in more than four years.
Group-wide net sales increased 20% to $200.6 billion, while operating income rose 43% to $27.5 billion. Amazon also raised its planned capital expenditure for 2026 to about $220 billion, highlighting its commitment to expanding AI infrastructure and cloud capacity.
Chief Executive Andy Jassy said AWS was experiencing exceptional demand, driven by rapid growth in artificial intelligence services.
“Our AI and chips businesses each eclipsed run rates of more than $25 billion,” Jassy said. He also pointed to record delivery speeds for Prime members during the first half of the year, with same-day and overnight deliveries rising by more than 40% and grocery sales growing faster than the rest of the retail business.
Investor enthusiasm has spread across the wider technology sector. Amazon’s shares recorded their strongest three-day performance since October 2009, reflecting renewed confidence in companies investing heavily in AI.
Mark Hackett, chief market strategist at Nationwide, said Amazon had become a symbol of both consumer spending and the expanding AI economy.
“The big scepticism coming into earnings season was whether hyperscalers were slowing AI investment,” Hackett said. “The results from Amazon and Microsoft showed that spending remains strong, giving investors greater confidence across the market.”
AWS continues to expand globally, including in the United Kingdom, where Amazon has pledged £40 billion of investment over three years across fulfilment centres, film production and data centres. AWS has also committed £8 billion for UK data centres by 2028.
Demand for AWS capacity has been strengthened by major agreements with AI developers. Among the largest is a multibillion-dollar computing capacity deal signed with OpenAI in late 2025.
Founded by Jeff Bezos in 1994, Amazon has grown from an online bookseller into one of the world’s largest technology companies. Bezos remains the company’s largest shareholder, holding a stake of nearly 9%, as Amazon continues to expand its presence in cloud computing, artificial intelligence and digital commerce.
