AWS Notches Its Fastest Growth in 15 Quarters as Amazon Posts Record $181.5 Billion Q1 Revenue
Amazon's cloud division hit a $150 billion annualized run rate at 28% growth, while AI services crossed $15 billion and custom chips topped $20 billion.
Overview
Amazon reported first-quarter 2026 results on April 29, delivering $181.5 billion in net sales — a 17 percent year-over-year increase — while Amazon Web Services posted its fastest growth rate in 15 quarters. AWS revenue reached $37.6 billion, up 28 percent year-over-year, pushing the division to a $150 billion annualized run rate, according to Amazon’s earnings release. The quarter’s headline metric underscored a broader acceleration: AWS’s AI services business has already crossed a $15 billion annual revenue run rate, a milestone that CEO Andy Jassy described in historically striking terms.
AWS and AI: The Core Story
Jassy used the earnings call to frame Amazon’s AI position with a direct historical comparison: “Three years after AWS launched, it had a $58 million revenue run rate. In the first three years of this AI wave, AWS’s AI revenue run rate is over $15 billion — nearly 260 times larger,” he said.
AWS operating income reached $14.2 billion in the quarter, up from $11.5 billion a year earlier, at an operating margin of 37.7 percent, according to Yahoo Finance. The division’s contracted backlog stood at $364 billion, per Amazon’s release, excluding a separate large Anthropic commitment.
Custom silicon emerged as a distinct growth engine: Amazon’s chips business — spanning Graviton, Trainium, and Nitro — topped a $20 billion annual revenue run rate with triple-digit year-over-year growth. Jassy summarized the quarter’s performance: “AWS is growing 28% (our fastest growth in 15 quarters) on a very large base, our chips business topped a $20 billion revenue run rate (growing triple digits year-over-year), advertising grew to over $70 billion in TTM revenue, and unit growth in our stores reached 15% (the highest since the tail end of covid lockdowns),” according to Yahoo Finance.
Bedrock, Amazon’s managed AI services platform, saw particularly sharp adoption: it processed more tokens in Q1 than in all prior years combined, and customer spending on the platform grew 170 percent quarter-over-quarter, per Amazon. The agentic AI tooling layer is scaling as well — Jassy noted that AWS’s Strands framework had been downloaded more than 25 million times, according to the official earnings commentary.
Overall Financials
Beyond AWS, total operating income rose to $23.9 billion from $18.4 billion in the prior-year quarter, and net income reached $30.3 billion, or $2.78 per diluted share, versus $1.59 a year earlier, per Amazon’s release. The EPS figure comfortably exceeded analyst estimates of $1.64, according to Yahoo Finance. The company noted that the quarter’s net income included $16.8 billion in pre-tax gains from its Anthropic investment position.
Amazon’s operating margin reached 13.1 percent, described as the highest in the company’s history, as logistics efficiency and AWS profitability combined to lift margins across segments.
Advertising continued to outperform, with Jassy stating: “We continue working to be the best place for brands of all sizes to grow their businesses, and we’re pleased with the continued strong growth across our full funnel offerings, generating $17.2 billion of revenue in the quarter, and up 22% year-over-year,” according to Amazon’s official earnings commentary. Advertising trailing-twelve-month revenue has now surpassed $70 billion.
Capital Expenditure and the AI Infrastructure Trade-off
The headline results came alongside heavy capital spending. Amazon CFO Brian Olsavsky stated on the earnings call: “Our cash CapEx is $43.2 billion in Q1. This primarily relates to AWS and generative AI as we invest to support strong customer demand,” per the earnings call transcript.
The spending compressed free cash flow significantly. Trailing-twelve-month free cash flow fell to $1.2 billion from $25.9 billion, driven by a $59.3 billion increase in capital equipment purchases for AI infrastructure, according to Amazon’s earnings release. Jassy defended the outlay by explaining the economic rationale: “AWS has to lay out cash for land, power, buildings, chips, servers, and networking gear in advance of when we can monetize it, typically 6 to 24 months before we start billing customers,” per the earnings call transcript. He added that the assets being built have long useful lives — “30+ years for data centers, 5 to 6 years for chips, servers, and networking gear.”
Olsavsky echoed the confidence about the multi-year build: “We’ll continue to make significant investments, especially in AI, as we believe it to be a massive opportunity with the potential to drive long-term revenue and free cash flow,” per the transcript.
What We Don’t Know
Amazon did not disclose the specific dollar value of the Anthropic Trainium commitment, which was excluded from the $364 billion AWS backlog figure. The company also provided no breakdown of AWS AI revenue by service category, making it difficult to assess which offerings are driving the $15 billion run rate. Additionally, the extent to which the Anthropic investment gains — $16.8 billion in Q1 alone — reflect a durable mark-to-market or a one-time revaluation remains unclear from the disclosed figures.
Guidance
For the second quarter of 2026, Amazon expects net sales of $194.0 to $199.0 billion, representing 16 to 19 percent year-over-year growth, per the earnings release. Operating income is expected between $20.0 and $24.0 billion. The company noted that its guidance assumes Prime Day occurs in the second quarter.
