Amazon just sent shockwaves through Wall Street. The e-commerce and cloud giant's stock cratered more than 10% in after-hours trading Thursday after the company missed earnings expectations and revealed plans to spend a staggering $200 billion on AI infrastructure in 2026 - roughly 36% higher than the $146.6 billion analysts anticipated. The spending bombshell, coupled with an earnings miss, marks one of the most dramatic post-earnings reactions for a big tech company this earnings season.
Amazon just reset the economics of the AI race, and investors aren't happy about it. The company's shares tumbled more than 10% in extended trading Thursday after CEO Andy Jassy revealed the tech giant plans to pour $200 billion into capital expenditures this year - a figure so massive it sent analysts scrambling to revise their models and competitors reconsidering their own spending plans.
The earnings report itself was a mixed bag. Amazon posted Q4 revenue of $213.39 billion, slightly beating the $211.33 billion analysts expected, according to LSEG data. But earnings per share came in at $1.95, missing the $1.97 consensus estimate. Net income hit $21.19 billion, up from $20 billion a year ago.
What really spooked Wall Street was the spending guidance. The $200 billion capex forecast represents a 36% increase over the $146.6 billion analysts had penciled in, according to FactSet. It's a bet-the-company-scale investment in data centers, AI chips, and cloud infrastructure that Jassy believes will pay off over the long term.
"With such strong demand for our existing offerings and seminal opportunities like AI, chips, robotics, low earth orbit satellites, we expect to invest about $200 billion in capital expenditures across Amazon in 2026, and anticipate strong long-term return on invested capital," Jassy said in a statement released Thursday.
The announcement positions Amazon at the center of an unprecedented capital spending spree among big tech companies. Google parent Alphabet said Wednesday it expects to spend between $175 billion and $185 billion in 2026, while Meta projected capex could nearly double from last year to $115 billion to $135 billion. The collective spending by these three companies alone could exceed half a trillion dollars this year.
But there's a bright spot buried in the results that explains why Amazon's willing to open the spending floodgates: Amazon Web Services is accelerating. The cloud computing division posted revenue of $35.58 billion in Q4, beating StreetAccount estimates of $34.93 billion and growing 24% year-over-year. Jassy called it AWS' "fastest growth in 13 quarters" - a critical data point as the company battles perceptions it's losing ground to Microsoft and Google in AI.
The competitive dynamics are getting intense. Microsoft Azure recorded 39% growth last week, while Google's cloud revenue jumped 48% - its fastest expansion since 2021. Amazon remains the cloud infrastructure leader, but the gap is narrowing as enterprises rush to deploy AI applications and competitors pour billions into GPU clusters and custom AI chips.
Amazon's advertising business continues to be a quietly massive revenue driver. The unit pulled in $21.3 billion in Q4, up 23% year-over-year and slightly ahead of the $21.16 billion StreetAccount estimate. The advertising segment has become Amazon's third major profit engine alongside e-commerce and AWS, giving the company more financial flexibility to fund its AI ambitions.
The spending spree comes as Amazon simultaneously cuts costs elsewhere. The company announced plans last week to lay off about 16,000 corporate employees, following roughly 14,000 job cuts last October. Amazon's total headcount stood at 1.57 million employees globally at the end of December, up just 1% year-over-year, with most workers in warehouse and logistics roles.
For the current quarter, Amazon projected sales between $173.5 billion and $178.5 billion, representing growth of 11% to 15%. Analysts polled by LSEG had expected $175.6 billion - putting Amazon's guidance right in line with Street expectations for its core business.
The real question facing investors now is whether Amazon's AI infrastructure bet will generate the returns Jassy is promising, or if the company is overbuilding capacity in a market where demand remains uncertain. The $200 billion figure is eye-popping even by big tech standards, and it signals Amazon believes the AI opportunity is big enough to justify spending that would fund entire countries' infrastructure budgets.
Amazon's $200 billion spending commitment represents the most aggressive AI infrastructure bet in corporate history, dwarfing even Google's eye-popping forecast from a day earlier. The immediate market reaction suggests investors are spooked by the scale of the investment and the near-term pressure it'll put on margins. But Jassy is making a calculated wager that whoever builds the biggest, most advanced AI infrastructure will control the cloud computing market for the next decade. With AWS already showing its fastest growth in over three years, Amazon has momentum. The question is whether $200 billion in capex will cement that lead or become a cautionary tale about overinvestment in an uncertain market. Wall Street will be watching closely to see if AI demand justifies the spending - and whether Amazon can maintain its cloud leadership as Microsoft and Google come charging hard.
