AI Infrastructure Stocks Set to Outpace S&P 500 in 2026

Wall Street’s biggest names are betting their balance sheets on artificial intelligence, and the picks and shovels crowd is quietly turning into the loudest winner of the year. With combined hyperscaler spending now blowing past every old forecast, the case for AI infrastructure stocks beating the broader market in 2026 is looking stronger by the week. The numbers tell a story you cannot ignore.

The $725 Billion Capex Wave Reshaping the Market

The four biggest cloud platforms have moved from cautious to all in. Google, Amazon, Microsoft, and Meta plan to spend a combined $725 billion on capital expenditure in 2026, a 77% increase over last year’s record $410 billion, according to first-quarter earnings reports compiled by the Financial Times.

That figure keeps climbing. Microsoft, Alphabet and Meta once again raised their spending forecast for 2026, while Amazon stuck with its February projection of $200 billion. The four companies are now expecting to invest up to $725 billion this year, most of it on AI infrastructure.

This is the largest single-year corporate buildout in modern tech history, and almost every dollar lands inside the AI supply chain.

Here is how the 2026 capex plans stack up across the four giants:

Why Demand Is Outrunning Supply Right Now

The story is no longer about future hope. It is about contracts already signed. All the hyperscalers report that their markets are supply-constrained, rather than demand-constrained.

Amazon’s leadership made the urgency plain. “AI is a once-in-a-lifetime opportunity where the current growth is unprecedented and the future growth even bigger,” Amazon CEO Andy Jassy recently wrote in his annual letter to shareholders. “We’re not going to be conservative in how we play this. We’re investing to be the meaningful leader, and our future business, operating income, and FCF will be much larger because of it.”

The numbers from inside the cloud business back him up. AWS grew 28% year-over-year, its fastest rate in 15 quarters, on a $150 billion annualized revenue base. Growing 28% when you are already a $150 billion business should not be possible. It is happening anyway.

Alphabet’s signal was even louder. Alphabet’s Google Cloud revenue grew 63% year-over-year to $20 billion, more than doubling its growth rate. The enterprise cloud computing segment backlog is $462 billion, which nearly doubled this quarter compared to last quarter. Alphabet plans to see just north of 50% of that backlog turn into revenue over the next 24 months.

“As fast as we install this AI capacity, it’s getting monetized.” Andy Jassy, CEO, Amazon

The Real Winners: Chips, Power and Networking

When hyperscalers spend, suppliers cash the checks. CreditSights estimates roughly 75% of that spend, about $450 billion, goes directly to AI infrastructure including GPUs, servers, networking equipment, and data centers.

Nvidia remains the headline name, but the field is widening fast. Here are the segments pulling in the biggest dollars right now:

• GPU makers: Nvidia still captures the lion’s share of accelerator spend.
• Custom silicon designers: Broadcom designs custom ASICs for Apple, Meta, Alphabet, and ByteDance, hyperscalers increasingly building proprietary chip architectures to complement Nvidia hardware.
• Memory and storage: Flash memory provider SanDisk has risen a remarkable 464.5% in 2026 with a share price that has exploded to over $1,500 from $34 a year ago.
• Power and cooling: Vertiv, Eaton and utility names tied to data center load growth.
• Foundries: TSMC, the chip fab nearly every AI processor passes through.

Amazon’s own chip business is no longer a side show. Amazon’s custom silicon business, primarily its Trainium AI chip and Graviton CPU, has an annualized revenue run rate of over $20 billion, growing triple digits. If Amazon accounted for internally consumed chips the way standalone chip companies do, the revenue run rate would exceed $50 billion.

Microsoft’s AI revenue is scaling at a pace Wall Street rarely sees. Its AI business surpassed $37 billion in annualized revenue, growing 123% year-over-year.

Valuations Look Friendlier Than Most Investors Think

For all the headline spending, share prices have not always followed in a straight line. Earlier this year, some investors rotated out, and that pullback left several names looking cheaper relative to earnings than they have in years.

Wall Street has consistently underestimated the size of this wave. Consensus capex estimates have proven to be too low for two years running. At the start of both 2024 and 2025, consensus estimates implied capex growth of roughly 20% for the year. In reality, it exceeded 50%.

Earnings growth is also doing the heavy lifting. Alphabet, Amazon, and Meta pushed S&P 500 earnings growth to more than 27%, which would be the highest level since 2021, FactSet senior earnings analyst John Butters wrote in a May 4 note.

When earnings rise faster than stock prices, multiples compress. That is the textbook setup for outperformance.

The Risks Every Investor Should Watch

This story is not without bumps. Capex of this size eats free cash flow, and not every company will pass the test.

The strain is already visible. Amazon’s free cash flow collapsed to $1.2 billion as a $59.3 billion year-over-year surge in infrastructure spending consumed nearly all of its operating cash flow.

Component prices are also adding pressure. The International Data Corporation forecasts that DRAM will cost $9.71 per gigabyte in 2026, compared to $3.76 in 2025. Spot prices for Nvidia H200 GPUs have risen sharply. Microsoft attributed roughly $25 billion of its 2026 capex to component price inflation, a figure that underscores how much of the spending increase is cost-driven, not purely demand-driven, capacity expansion.

There are physical limits too. Power infrastructure is another bottleneck, with large power transformer lead times extending to roughly 128 weeks, and the IEA estimating that approximately 20% of planned global data center projects could be at risk of grid-related delays.

Skeptics point to ratios that have rarely held up over time. Capex-to-revenue ratios have reached historically elevated levels: Meta is tracking toward capex equal to roughly 54% of sales, Microsoft 47% and Alphabet 46% in 2026.

What Smart Money Is Doing Next

The playbook is becoming clearer with every earnings call. Investors who want exposure without overpaying for one name are spreading bets across three layers of the AI economy.

1. Builders: The hyperscalers themselves, who own the customer relationships.
2. Enablers: Chip designers, memory makers, foundries, power utilities and cooling specialists.
3. Appliers: Software firms that turn AI into recurring revenue inside enterprises.

For 2026, the enabler basket has been the standout. The average stock in Goldman Sachs Research’s basket of infrastructure companies returned 44% year-to-date, compared with a 9% increase in the consensus two-year forward earnings-per-share estimate for the group.

The takeaway for everyday investors is simple. The AI buildout is not slowing down. It is accelerating, contracted, and increasingly profitable for the companies selling the picks and shovels. Investors who own a basket of well-priced infrastructure names heading into the back half of 2026 have a reasonable shot at beating the broader index, especially if hyperscalers raise guidance again, which they have done at every recent earnings cycle.

The AI revolution is no longer a slide deck or a hopeful pitch. It is a measurable, multi-hundred-billion-dollar reality showing up in real revenue, real backlogs, and real factory orders. For the millions of everyday investors who felt left behind by the first leg of this rally, the second leg may be the one that finally pays off.
