TL;DR
Amazon (AMZN—
Spot ·
Futures) crossed a $3 trillion market cap for the first time on August 3, 2026, driven by AWS revenue growth of 37% — its fastest pace in 18 quarters.
Alphabet's Gemini-powered AI push has closed much of the valuation gap with Apple this year, though as of the most recent data Apple still holds the larger market cap of the two.
Palantir's Q2 results, released the same week, add a third data point to the same story: AI infrastructure spending is starting to show up directly in enterprise revenue, not just in capex announcements.
This is a snapshot of where things stand, not a forecast — figures are sourced and dated below.
Amazon Hits a $3 Trillion Market Cap After Strong AWS Earnings
Amazon's stock hit a new all-time high on August 3, 2026, pushing its market capitalization above $3 trillion for the first time, according to CNBC. Shares closed up roughly 4%, capping the company's best trading day since early May and extending a rally that began after its second-quarter earnings report landed the previous week.
The number behind the milestone is AWS. According to
Yahoo Finance's earnings coverage, Amazon Web Services generated $42.2 billion in second-quarter revenue, up 37% year-over-year — its fastest growth rate in 18 quarters, and well ahead of the roughly 31% analysts had penciled in. Total company revenue crossed $200 billion in a single quarter for the first time, coming in at $200.6 billion against a Wall Street forecast of $196.5 billion. Adjusted earnings per share landed at $1.97, versus an expected $1.82.
Amazon's own commentary on the call is worth noting for anyone tracking the broader AI infrastructure story. CEO Andy Jassy told investors that even after raising 2026 capital expenditure guidance from $200 billion to $220 billion — a jump largely attributed to rising memory chip costs — the company still won't have enough server capacity to meet demand this year, and expects the same constraint to persist through 2027. He added that early demand signals for 2028 are already "striking," per the same Yahoo Finance report.
That's a notable shift in how the market is reading heavy AI spending. Historically, large capex raises have made investors nervous about near-term margins. This time, according to TipRanks, analysts framed the AWS acceleration as evidence the capex bet is starting to pay off, with Philip Securities analyst Helena Wang writing that AWS growth is beginning to "justify" the spending. Amazon reached its first $2 trillion valuation in June 2024, meaning the jump to $3 trillion took a little over two years — a pace that puts it alongside Apple, Microsoft, Alphabet, and Nvidia as the only companies to have ever crossed that threshold, according to Quartz.
There's a margin story underneath the headline growth number that's worth unpacking, too. AWS posted operating margins of 39% in the quarter, according to reporting from
CryptoBriefing — a figure that stands out even by cloud-infrastructure standards, where fixed costs from data centers and chips are typically heavy. That combination of accelerating growth and expanding margin is precisely what separates "spending on AI infrastructure" from "monetizing AI infrastructure," and it's the distinction investors have been waiting to see across the entire hyperscaler group. Amazon also disclosed that its AI and semiconductor businesses have each individually surpassed annualized revenue run rates of $25 billion — a detail that suggests the AI buildout is no longer a single line item but is starting to fragment into multiple billion-dollar businesses within the company.
Alphabet vs Apple Market Cap: Who Is Worth More in 2026?
Alphabet's AI-driven rally has been one of the more closely watched storylines of 2026, and for good reason: the company briefly overtook Apple in market capitalization back in January, the first time it had done so since 2019, according to
CNBC's coverage at the time. That flip was driven by a combination of Alphabet's 65% stock gain in 2025 — the best performance among the "Magnificent Seven" — and renewed confidence in Google's Gemini 3 model, alongside a rough start to the year for Apple shares.
As of the most recent data available, though, Apple has since widened its lead back out. Market-cap trackers including GuruFocus put Apple's valuation at roughly $4.54 trillion as of August 3, 2026, while companiesmarketcap.com and StockAnalysis put Alphabet (GOOGL —

Futures ) at roughly $4.35–4.36 trillion over the same window — a gap of somewhere around $180 billion in Apple's favor. Both remain behind Nvidia, which sits at the top of the rankings with a market cap in the $4.9 trillion range according to The Motley Fool's running list of the largest public companies.
The bigger-picture read is less about who's ahead on any single day and more about the trajectory. Alphabet's capital expenditures have surged as it builds out AI infrastructure — Google Cloud revenue grew 82% in its most recent quarter, according to reporting cited by CNBC alongside the Amazon earnings coverage — and its custom TPU chips have become a genuine competitive alternative to Nvidia for some AI workloads. Whether that closes the remaining gap with Apple, or whether Apple's own AI rollout (including its recently announced partnership to use Google's Gemini as the foundation for a rebuilt Siri) stabilizes its position, is very much an open question rather than a settled one.
How Palantir's Earnings Support the AI Infrastructure Story
Palantir's second-quarter results, released the same week, round out the picture. The company reported 93% year-over-year revenue growth, with commercial revenue — arguably the segment most exposed to genuine enterprise AI adoption rather than government contracts — surging 149%. Adjusted operating margin came in at 62%, and the company raised its full-year revenue growth guidance for the third consecutive time this year, now guiding to roughly 82% growth.
Taken together with Amazon's AWS numbers and Alphabet's cloud growth, Palantir's results point to the same underlying shift: AI infrastructure spending is beginning to show up as measurable revenue growth at the application layer, not just as capex line items on balance sheets. That's a different narrative than the one dominating headlines for much of 2025, when the conversation centered almost entirely on how much capital was being spent and whether it would ever be recouped.

What makes the Palantir number worth flagging alongside two much larger companies is where the growth is coming from. Palantir's business has historically leaned heavily on government and defense contracts — a durable but slower-growing revenue base. A 149% jump in commercial revenue specifically suggests private-sector enterprises are now adopting Palantir's AI tooling at a pace that wasn't previously the norm for the company. Combined with a 62% adjusted operating margin, that's a meaningfully different profile from a company burning cash to acquire AI customers — it's closer to the same "growth plus expanding margin" pattern showing up at AWS.
What Investors Should Watch After Amazon's $3 Trillion Milestone
Two more data points are due after markets close today, August 4, 2026: Advanced Micro Devices and SpaceX are both scheduled to report earnings. AMD's results will be watched closely for data center revenue, MI-series AI GPU shipment numbers, and any signs of share gains against Nvidia in the AI accelerator market. SpaceX's report is a genuinely novel data point — it's the company's first earnings release since going public — and investors will be looking at Starlink subscriber growth, the scale of AI-related capital spending and losses, and progress on Starship development. Because neither report exists yet at the time of writing, drawing conclusions from them now would be speculation rather than analysis; both are better covered once the actual numbers are in.
For now, the throughline across Amazon, Alphabet, and Palantir is consistent: the market is rewarding companies that can show AI infrastructure spending converting into revenue growth, and increasingly discounting the ones that can only point to future potential. Amazon's AWS acceleration and Palantir's commercial revenue surge are two of the clearest examples of that conversion actually happening in the numbers, as opposed to being promised for later.
FAQ
Did Amazon really just hit $3 trillion for the first time?
Yes. Amazon's market cap crossed $3 trillion for the first time on August 3, 2026, according to CNBC, following a stronger-than-expected Q2 earnings report the previous week.
Is Alphabet currently worth more than Apple?
No, not as of the most recent data. Alphabet briefly overtook Apple in market cap in January 2026, but Apple has since regained the larger valuation — roughly $4.54 trillion versus Alphabet's $4.35–4.36 trillion as of early August 2026, per GuruFocus and companiesmarketcap.com.
What drove Amazon's AWS growth to an 18-quarter high?
AWS revenue grew 37% year-over-year to $42.2 billion, driven by accelerating demand for cloud infrastructure that supports AI workloads, alongside 39% operating margins on that segment.
Is Palantir's growth connected to the same AI infrastructure story as Amazon and Alphabet?
It's a related but distinct data point. Where Amazon and Alphabet are the infrastructure providers seeing rising cloud demand, Palantir sits closer to the application layer — its 149% commercial revenue growth suggests enterprises are increasingly paying for AI tooling built on top of that infrastructure, not just the infrastructure itself.
