Amazon market cap tops $3 trillion for first time

• AMZN: -1.72%
• NVDA: +3.43%
• GOOG: -4.05%

Amazon (NASDAQ: AMZN) closed at $284.02 on Monday, up more than 4% for the day and at a record high. That price values the e-commerce and cloud computing giant just above $3 trillion — a level it had never reached before. Getting from here to a $4 trillion valuation would require approximately a 31% gain, bringing the stock price to around $371.

Amazon would not be the first to reach that milestone. Nvidia is already worth about $5 trillion, and Alphabet sits at approximately $4.6 trillion.

The Growth Behind the Milestone

Monday's record came after last week's second-quarter report gave investors plenty to like:

• Net sales rose 20% year over year to $200.6 billion.
• Operating income climbed 43% to $27.5 billion, up from $19.2 billion a year earlier.

Growth was not confined to the cloud:

• North America sales rose 16% year over year.
• International sales rose 15%.
• Advertising revenue grew 26% year over year.

However, Amazon Web Services (AWS) was the standout. The cloud computing segment grew sales 37% year over year to $42.2 billion in the second quarter — its fastest rate in 18 quarters — and its operating income rose approximately 63% to $16.6 billion.

The segment's economics explain why it matters so much. For every dollar of sales AWS booked in the quarter, it earned about $0.39 of operating income. The rest of Amazon earned about $0.07.

Reported net income looked even larger ($62.6 billion, or $5.75 per share), but investors should be cautious with that figure. It includes $53.4 billion of non-operating income, mostly from marking up the value of Amazon's investments in AI developer Anthropic. That is an accounting gain, not money the stores or the cloud earned. Operating income is the sturdier yardstick.

Demand does not appear to be the constraint, either. CEO Andy Jassy said on the earnings call that Amazon now plans approximately $220 billion of capital spending this year, up from the $200 billion it projected in February. He added that even that amount will not buy enough capacity to meet all the demand the company already has for 2026 — a dynamic he believes will hold in 2027 as well.

The Road to $4 Trillion

The math from here is simple. Shares trade at about 31 times forward earnings estimates. A valuation like that already expects a lot, though it is arguably earned when operating income just grew 43%.

If that valuation multiple simply holds, the stock follows earnings — and earnings would need to rise about 31% to justify $4 trillion. Growth like last quarter's, sustained for even a year, would more than cover the climb.

These milestones have also been arriving quickly across big tech. Nvidia became the first company ever to reach $4 trillion just over a year ago, in July 2025, and it has kept climbing since. Today, $4 trillion would not even make Amazon the largest company on the market.
