Amazon closed out Big Tech's AI-driven earnings season on July 31 with arguably the cleanest good-news story of the bunch. While Meta and Alphabet both posted strong quarters shadowed by investor anxiety over ballooning capital spending, Amazon Web Services delivered its fastest growth in five years, and the company's headline profit figure got an extraordinary, if somewhat misleading, boost from an entirely separate source: its investment in the AI research company Anthropic.

The number that actually matters: AWS reaccelerating

Amazon's cloud computing division posted revenue of $42.2 billion for the second quarter, up 37% year over year, marking the fifth consecutive quarter of accelerating growth and AWS's fastest expansion pace since 2021. That figure comfortably beat analyst expectations of roughly $40.54 billion and outpaced the 31% growth Wall Street had projected for the segment. CEO Andy Jassy highlighted the acceleration directly in the company's earnings statement, noting that AWS is "booming, growing 36.7% year-over-year in Q2," and that the company's AI and custom chips businesses have each individually surpassed $25 billion in annualized revenue run rate.

AWS operating income reached $16.6 billion for the quarter, up 64% from $10.2 billion a year earlier, pushing the division's operating margin to 39.4%, an expansion of roughly 650 basis points year over year. On an annualized basis, AWS is now running at a $169 billion revenue rate, a figure Jassy noted during the earnings call would rank AWS 24th on the Fortune 500 list if it operated as a standalone company.

A backlog that answers the demand question directly

Perhaps the single most important number in Amazon's entire report was its AWS backlog, which reached $496 billion in contracted future business, growing at a triple-digit percentage pace. That backlog matters enormously in the context of the broader debate rattling AI infrastructure investors all summer: whether hyperscalers' enormous capital spending increases are chasing real, already-committed demand or simply speculative capacity nobody has agreed to buy yet. A nearly $500 billion contracted backlog growing at triple-digit rates offers about as clear an answer as a single earnings report can provide, at least for Amazon's specific slice of that broader industry-wide spending debate.

Jassy reinforced that demand narrative on the earnings call, telling analysts that even after Amazon's latest capital expenditure increase, the company "will still not have enough capacity to meet all the demand" it expects during 2026, a comment that frames Amazon's spending less as a bet on future growth and more as a scramble to keep pace with growth that has already arrived.

The rest of the business held up well too

AWS wasn't the only bright spot. Total net sales reached $200.6 billion for the quarter, up 20% year over year and ahead of the roughly $196.47 billion analysts had modeled. Operating income across the entire company rose 43% to $27.5 billion, pushing overall operating margin to 13.7%, a record for the company and a meaningful improvement from 11.4% a year earlier. Advertising services revenue grew 26% to $19.8 billion, while North America segment sales rose 16% to $116.2 billion and international segment sales increased 15% to $42.2 billion.

Why the headline profit number needs an asterisk

Amazon's reported net income for the quarter reached $62.6 billion, or $5.75 per diluted share, more than triple the $18.2 billion, or $1.68 per share, reported in the same quarter a year earlier. Taken at face value, that looks like an almost unbelievable earnings jump. It largely is, but not because Amazon's underlying retail and cloud businesses suddenly became three times more profitable.

The company disclosed that second-quarter net income included $53.4 billion in non-operating pre-tax income, driven primarily by an upward revaluation of Amazon's equity stake in Anthropic, the AI research company in which Amazon has invested heavily. That single line item accounts for the overwhelming majority of the quarter's net income growth. Amazon also recorded a related $15.9 billion net discrete tax expense for the first half of the year, tied to the same upward adjustment in the Anthropic investment's value. Strip out that non-operating gain entirely, and Amazon's underlying operating performance still looks genuinely strong, with operating income up 43% on its own merits, but nowhere near the tripling suggested by the unadjusted net income figure alone.

Capital spending keeps climbing, and cash flow shows it

Amazon raised its full-year 2026 capital expenditure guidance to approximately $220 billion, reflecting continued investment in AWS infrastructure and broader AI capacity. Cash capital expenditures reached $53.1 billion in the second quarter alone. On a trailing twelve-month basis, property and equipment purchases climbed to $169 billion, up 64% year over year.

That spending pace has pushed Amazon's free cash flow into negative territory for the first time in recent memory, with trailing twelve-month free cash flow swinging to an outflow of roughly $7.6 billion, compared to a positive $18.2 billion inflow over the same period a year earlier. Operating cash flow, meanwhile, actually grew a healthy 33% to $161.4 billion on a trailing twelve-month basis, meaning the negative free cash flow figure reflects aggressive investment rather than any weakening in the underlying cash-generating power of Amazon's operations, a distinction that echoes the pattern seen recently at both Meta and Alphabet.

Guidance suggests a modest deceleration ahead

For the third quarter, Amazon guided toward net sales of $197 billion to $202 billion and operating income of $22.5 billion to $26.5 billion, a range that implies growth continuing but at a somewhat more measured pace than the second quarter's results. That guidance came in below what some analysts had hoped for, a detail that tempered an otherwise strongly positive market reaction to the earnings release itself.

How Amazon's quarter fits the broader Big Tech pattern

Amazon's results landed at the tail end of a earnings season in which Alphabet, Meta, and now Amazon have each reported enormous capital expenditure increases tied to AI infrastructure buildout, with combined 2026 spending across the largest hyperscalers now projected to approach $700 billion. What differentiates Amazon's specific report from Meta's, where free cash flow collapsed 91% amid legal charges and severance costs with far less backlog visibility to reassure investors, is the sheer size and growth rate of AWS's contracted backlog. A nearly $500 billion pipeline of already-signed future business gives Amazon a considerably stronger evidentiary basis for its spending plans than a company relying primarily on projected future demand.

Whether that backlog converts into sustained profit growth at the margins AWS is currently posting will be the central question shaping how investors judge Amazon's enormous capital commitments over the next several years, but for at least one quarter, the underlying demand signal looks about as clear as this AI-driven spending cycle has offered any single company so far.
