Amazon Is 5.5% Away From a $3 Trillion Market Cap — AWS Up 28% Is Driving the Revaluation

Amazon hit an all-time high on May 5, coming within billions of a $3 trillion market cap. At $2.84 trillion, it sits 5.5% away from that milestone. The engine behind this run is AWS — up 28% in Q1 with operating margins above 35% for the third straight year.

Only four U.S.-listed companies have crossed $3 trillion in market capitalization. Amazon is closing in on becoming the fifth. After hitting an all-time high on May 5 and briefly approaching the milestone, shares pulled back modestly. At $2.84 trillion, Amazon is now 5.5% away from the mark — and the fundamentals suggest it will get there.

5.5% Away — With 33% Momentum Behind It

Despite a recent pullback, Amazon shares are up 33% over the past three months. That momentum is grounded in accelerating fundamentals. Q1 2026 net sales rose 17% year over year — Amazon's fastest top-line growth rate in nearly five years.

Notably, market sentiment has shifted. Earlier this year, Amazon's announcement of $200 billion in capital expenditures for 2026 initially rattled investors. Three months later, the same number is being reread as evidence of AI infrastructure dominance in the making.

AWS: 20% of Revenue, Over Half of Operating Profit

The repricing of Amazon stock is fundamentally an AWS story. In Q1 2026, AWS net sales grew 28% year over year — the strongest pace in more than three years — driven by surging demand for AI compute and ongoing enterprise cloud migration.

• AWS net sales growth: +28% YoY (strongest in 3+ years)
• AWS operating margin: above 35% for the third consecutive year
• AWS share of Amazon total net sales: approximately 20%
• AWS share of Amazon total operating profit: over 50%

AWS accounts for a fifth of Amazon's revenue but more than half its operating profit. Unlike the historically thin-margin e-commerce business, AWS is a high-margin flywheel that AI demand is spinning faster.

Building Its Own AI Chips — Reducing Nvidia Dependence

Amazon is not just riding the AI wave through AWS customer spending. It is developing its own AI accelerator chips for internal AWS use and, increasingly, opening them up to third-party customers. This chip strategy is a deliberate move to reduce Nvidia GPU dependency while improving infrastructure margins. AI is not just a top-line driver for AWS — it is a margin improvement lever as well.

The $3 Trillion Question: When, Not If

At roughly 30 times forward earnings, Amazon shares are not cheap. But for a company where revenue growth is accelerating, AWS margins are expanding, and AI infrastructure investment is beginning to pay off across multiple business lines, the premium appears defensible. The primary obstacle to reaching $3 trillion soon would be a broad market correction. Absent that, the direction of travel looks clear.
