Amazon and Alphabet have committed roughly $420 billion to capital expenditures, a combined outlay that signals the next phase of AI infrastructure build-out is already funded. The two companies are directing cash toward data centers, chips, and networking at a scale that leaves little room for suppliers to miss the cycle.
The spending breakdown
At the midpoint of its guidance, Amazon expects to deploy $220 billion on capex. Alphabet has signaled about $200 billion. Both figures represent increases from the targets each company set at the start of the year, and Alphabet told investors on its first-quarter call that 2027 spending will step up meaningfully from 2026 levels. The revision upward coincided with the latest earnings cycle, not with a new product announcement.
Nvidia's position
Nvidia enters this cycle with the industry-standard GPU portfolio, which makes it the default vendor for the cloud operators writing the checks. The company posted 85 percent revenue growth in its most recent quarter despite a market capitalization above $5 trillion. Analysts model roughly 43 percent revenue growth for the next fiscal year, a pace that would be extraordinary for any company a fraction of Nvidia's size. The stock trades at 24 times forward earnings, a multiple that assumes the current trajectory holds but does not price in a dramatic acceleration.
Micron's memory play
Amazon explicitly cited memory-chip demand as a driver of its higher capex guidance. Prices for DRAM and NAND have surged as consumption outpaces supply. Sandisk disclosed that price increases accounted for roughly two-thirds of its revenue growth in its latest report. Micron management has said the market will remain tight beyond 2027, extending the window for margin expansion. The shares change hands at 5.6 times projected earnings for the fiscal year ending August 2027, a valuation that reflects skepticism about the durability of the cycle rather than the near-term fundamentals.
What to watch
The next inflection point arrives when Nvidia reports its fiscal second-quarter results later this month. Beyond the headline numbers, the commentary on 2027 order visibility from both cloud buyers and chipmakers will determine whether the current spending trajectory is a ceiling or a floor.
