A rise in Amazon Net Providers spending minimize into the cloud big’s income within the second quarter as AWS raced to fulfill demand for AI in opposition to Microsoft, Google, and others.
Whereas Amazon beat Wall Road’s general expectations, its shares fell in after-hours buying and selling as buyers centered on rising prices throughout the cloud unit, the corporate’s largest revenue engine.
AWS income grew 17.5% year-over-year to $30.9 billion, in step with estimates. However the prices of competing within the AI arms race had been evident within the cloud division’s income. AWS working earnings grew lower than 9% to $10.2 billion as its working bills surged to $20.7 billion, up from $16.9 billion a 12 months earlier.
This resulted in an working margin of 32.9% — the cloud big’s lowest profit-to-revenue ratio since late 2023, and effectively under the working margin of almost 40% within the first quarter.
On the corporate’s earnings name with analysts, Amazon CFO Brian Olsavsky attributed the strain on AWS’s revenue margin to a seasonal improve in stock-based compensation, unfavorable international alternate charges, and better depreciation prices from ongoing investments in AI infrastructure.

Afterward the decision, analysts pressed Amazon CEO Andy Jassy to answer a “Wall Road narrative” that the corporate is falling behind rivals Microsoft and Google in pursuing the AI alternative.
Amazon’s outcomes got here a day after Microsoft disclosed annual income of greater than $75 billion for its Azure cloud platform, with quarterly progress of 39%, far exceeding expectations.
Google Cloud’s annual income run charge is greater than $50 billion, with quarterly progress of 32% year-over-year, based on numbers disclosed by Google mum or dad Alphabet final week.
AWS is a considerably bigger enterprise, with an annual income run charge of greater than $123 billion, making it rather more tough to generate eye-popping progress charges.
However even at that dimension, Morgan Stanley analyst Brian Nowak requested Jassy if it could be doable for AWS progress to speed up for the rest of 2025, “given the dimensions of the chance” and the amount of the generative AI workloads anticipated to return on-line within the subsequent 12 months.
Whereas Jassy declined to present particular steerage for the AWS section, he mentioned he’s “optimistic in regards to the AWS enterprise” and its potential to speed up.
He cited a mixture of things, together with extra enterprises resuming their migrations from on-premises knowledge facilities to the cloud, the anticipated improve in corporations deploying AI purposes into manufacturing, and extra AWS capability coming on-line within the coming months.
Jassy described long-term strategic benefits for AWS, together with the truth that AI inference will ultimately be handled as “one other constructing block” like compute, storage and database.
Due to this, he mentioned, many shoppers will wish to run their AI purposes near the place their different purposes and knowledge already reside — creating a strong benefit for Amazon, as a result of “there’s simply so many extra purposes and knowledge operating in AWS than anyplace else.”
Jassy mentioned AWS has a key benefit with its custom-built chips, which he mentioned provide 30% to 40% higher price-performance for inference than different GPU suppliers.
He additionally pointed to what he known as a “very large distinction” in safety — alluding to issues which have plagued Microsoft with out naming the corporate straight — and famous that AWS has a extra vital, end-to-end set of AI providers “from the underside of stack all the best way to prime.”
AI milestones for the corporate within the latest quarter included the launch of Kiro, a brand new agentic built-in growth atmosphere (IDE) that lets builders code in pure language, whereas the system robotically creates documentation and specs, and scans for safety points.
The corporate reported $31.4 billion in capital expenditures for the second quarter, up from almost $25 billion within the first quarter, most of it associated to expertise infrastructure. Amazon’s capex quantity just isn’t straight corresponding to Microsoft and Google as a result of its further investments in achievement facilities and its Mission Kuiper satellite tv for pc community.
Olsavsky mentioned AWS will proceed to take a position extra capital in knowledge facilities and different sources “to pursue this unusually massive alternative that now we have in generative AI.” Working margins, he mentioned, will “fluctuate over time, pushed partly by the extent of investments we’re making.”
