Amazon's Best Day in 11 Years: AWS Booms, Capex Hits $220B

AWS grew 37%, its fastest in 18 quarters, and the stock had its best day in 11 years β€” but the $5.75 EPS carries a $53 billion Anthropic asterisk.

Amazon reported second-quarter results Thursday night, and by Friday’s close the market had delivered its verdict: a 15.3% gain, the stock’s best session in 11 years, worth roughly $390 billion in market value. The question hanging over the stock all year was whether AWS is winning the AI buildout or merely paying for it. The answer, for now, is winning.

The Quarter

Revenue of $200.6 billion rose 20% year over year, ahead of the roughly $196.5 billion consensus, and adjusted EPS of $1.97 beat the $1.82 LSEG estimate. The engine, though, was the cloud:

  • AWS revenue of $42.2 billion, up 37% β€” the fastest growth in 18 quarters, far ahead of the roughly 31% expected β€” a $169 billion annualized run rate.
  • AWS operating income of $16.6 billion (from $10.2 billion a year ago) at a 39.4% margin, up from 37.7% in Q1.
  • A $496 billion AWS backlog, growing triple digits year over year.
  • AI and chips each eclipsed $25 billion annual run rates, growing triple digits β€” underpinned by multi-year, multi-gigawatt Trainium commitments from Anthropic and OpenAI, and by a Bedrock platform that added OpenAI’s frontier models in June, where customers spent more in Q2 than in all prior quarters combined.

“AWS is booming, growing 36.7% year-over-year in Q2β€”our fastest growth in 18 quartersβ€”and our AI and Chips businesses each eclipsed run rates of more than $25 billion,” CEO Andy Jassy said in the release.

The rest held up: North America sales rose 16% to $116.2 billion (core retail’s fastest growth since 2021), advertising grew 26% to $19.8 billion, and total operating income rose 43% to $27.5 billion.

The $53 Billion Asterisk

The headline profit number needs a footnote. Net income was $62.6 billion, or $5.75 per share, against $1.68 a year ago β€” but that includes $53.4 billion of non-operating pre-tax income tied primarily to Amazon’s Anthropic investment. It is a valuation mark, not operating cash, which is why the adjusted $1.97 is the number to compare against estimates.

Cash runs the other direction. Free cash flow flipped to a $7.6 billion trailing-twelve-month outflow, from an $18.2 billion inflow a year earlier, on $54.2 billion of quarterly capital spending. Jassy raised the full-year capex forecast to $220 billion from $200 billion β€” rising memory prices are a named driver β€” and Amazon funded a slice with a surprise $25 billion bond sale on July 7, saying it will issue no more debt this year.

What Analysts Said

The target raises were close to unanimous:

  • JPMorgan’s Doug Anmuth β€” Buy, to $365 from $330, arguing the AI investments are visibly beginning to pay off.
  • Wells Fargo’s Ken Gawrelski β€” to $328 from $322; Amazon remains his top pick, with a major data-center capacity expansion expected in 2027.
  • RBC’s Brad Erickson β€” to $330 from $320, calling the print “exactly what bulls wanted,” with AWS margins implying AI may not depress capital returns as feared.
  • Jefferies’ Brent Thill β€” to $330 from $320, naming the real debate: negative free cash flow is “well understood,” so what matters is when AWS and AI monetization inflects ahead of the construction bills.
  • UBS’s Stephen Ju β€” to $318 from $305, citing the backlog’s growth visibility.

The Market’s Answer

Shares jumped about 10% after hours Thursday and never gave it back, closing Friday at $271.58, up 15.3% β€” the best day in 11 years, per MarketWatch, and within a few percent of the 52-week high. A striking reception for a company that just added $20 billion to its spending plan: Meta and Alphabet both fell after raising their own capex forecasts this season. The difference, in the market’s read, is that evidence of return β€” accelerating growth, expanding margins, a contracted backlog β€” arrived in the same print as the higher bill. Amazon also had room to run: it entered Friday up just 2% on the year, a megacap laggard, with Google Cloud having posted 82% growth and Azure 43% earlier in the season.

What to Watch

  • Don’t misread the Q3 guide. The $197–202 billion sales forecast sits below the roughly $204 billion consensus, but Amazon moved Prime Day into June, shifting revenue into Q2; excluding that timing, guided growth would be nearly 400 basis points higher. The $22.5–26.5 billion operating income range brackets the $24.9 billion consensus.
  • The capex bill is still rising. Jassy was blunt that even $220 billion leaves Amazon short of capacity through 2027 β€” “the demand we already have for 2028 is striking.” Memory supply and pricing, the same crunch tripling RAM prices everywhere else, is a named driver. Watch whether $220 billion holds.
  • Free cash flow and the backlog. The bear case is arithmetic: FCF is negative, debt is up, and the payoff rests on converting a $496 billion backlog into revenue at today’s margins. Watch backlog growth and the AWS margin line β€” 39.4% is the number that makes the story work.
  • The Anthropic mark. Anthropic’s valuation swings now move Amazon’s GAAP earnings by tens of billions in either direction. Adjusted EPS is the cleaner read until that changes.
