Here are the stock market's winners and losers of Big Tech's most critical earnings stretch

• Meta, Alphabet, Amazon, and Microsoft stocks have seen mixed moves after earnings.
• Big Tech is still all in on AI, with Meta, Alphabet, and Microsoft boosting spending plans.
• Cloud segment growth was key focus for Alphabet, Amazon, and Microsoft.

Wednesday marked the stock market's most critical day of earnings, and winners and losers have emerged on Thursday as investors react.

Meta Platforms, Alphabet, Amazon, and Microsoft all released quarterly results after the closing bell on Wednesday, accounting for roughly $11.5 trillion of market cap.

Unsurprisingly, AI took center stage, with investors welcoming cloud growth offsetting massive AI investments.

All four companies beat earning expectations on the top and bottom lines, but not all of the results wowed investors.

Here's the Big Tech's post-earnings scorecard.

Meta

Meta's ballooning AI spending overshadowed its first quarter earnings strength and the stock move reflected it.

The move: -9%

Why: Meta lifted its already hefty full year capital expenditures outlook.

The Facebook parent company told investors it now expects to spend $125 billion to $145 billion in 2026, a big jump from the $115 billion to $135 billion range they gave the quarter prior.

"This reflects our expectations for higher component pricing this year and, to a lesser extent, additional data center costs to support future year capacity," Meta CFO Susan Li said, adding "We have continued to underestimate our compute needs," she added

CEO Mark Zuckerberg said the jump in spending is due to higher component costs, specifically memory chips.

Alphabet

Google's results wowed Wall Street with strength in its cloud business supporting AI spending.

The move: +7%

Why: Google Cloud is growing, thanks to AI.

Alphabet reported its cloud business recorded $20 billion in revenue, beating estimates, driven by its enterprise AI offerings.

"We are seeing strong deal momentum, doubling the number of $100 million to $1 billion deals year-on-year and signing multiple $1 billion-plus deals," Alphabet CEO Sundar Pichai said on the earnings call.

He reported, "In Q1, revenue from products built on our GenAI models grew nearly 800% year-over-year."

Like Meta, Alphabet also boosted its full year capex outlook, but investors didn't seem to mind. The Google parent company expects to spend between $180 billion and $190 billion this year, compared to the $175 billion to $185 billion range previously provided.

Amazon

Amazon stock popped after the company reported strong cloud growth and offered a look at its AI chip business.

The move: +2%

Why: Amazon Web Services saw its strong growth and the company offered a promising update on the chip business.

AWS revenue grew 28% to $37.6 billion, beating estimates of $37 billion. Like Alphabet, strength in Amazon's cloud business has helped ease investor worries about massive AI spending.

In other news, CEO Andy Jassy said Amazon's Trainium AI chips will be ready to sell to outside customers in the next couple of years.

Amazon didn't update its $200 billion capex guidance for 2026.

Microsoft

Microsoft boosted its AI spending plans, but cloud strength seemed to avoid investor panic, muting losses.

The move: -3%

Why: Microsoft lifted its annual capex guidance to $190 billion for the fiscal year, a notable jump from the $147 billion analysts expected.

Cloud revenue was $54.5 billion, a 29% rise from the year-ago period. Microsoft's cloud business is growing, but it's still lagging the timeline investors hoped for to offset spending.

"We remain confident in the return on these investments," Microsoft CFO Amy Hood said, adding that the increased spending will restrain short-term revenue growth.

Microsoft, along with Meta, plans to cut its head count in the quarters ahead.
