AWS Q2 2026 — Reacceleration to 37%, Margin and All

The setup

Amazon reported Q2 2026 after the close into the same debate that had just repriced the group: not whether the AI build is real, but whether the cloud growth on the other side of it justifies the cash going in. One week earlier, Alphabet was sold ~15% for raising capex; days before that, Microsoft was rewarded for guiding capex higher because Azure demand read as capacity-constrained. AWS walked in as the swing vote — the largest cloud, but the one whose growth had cooled to the mid-20s percent while its capex ran toward $200B. The question on the table was blunt: can AWS reaccelerate enough to earn the spend? It answered yes, and then added the part the bears did not have priced — it reaccelerated and expanded margin in the same quarter.

AWS is the profit engine of Amazon — a low-double-digit share of revenue that throws off the majority of consolidated operating income — so the segment line, not the $200.6B top line, is where this print lives. The second quarter (ended June 30, 2026) is the one in which AWS's growth rate turned back up, its custom-silicon franchise crossed from story to booked commitment, and the mark-to-market on Amazon's Anthropic stake made the GAAP bottom line briefly meaningless.

The numbers

Consolidated net sales were $200.6B, +20% year-over-year (from $167.7B). Operating income was $27.5B, +43%, with operating margin widening to 13.7% — the clean read on the quarter. The segments: AWS $42.2B, +37%, with operating income of $16.6B (from $10.2B a year ago, +63%) at a 39.4% operating margin; North America $116.2B (+16%, $9.1B operating income); International $42.2B (+15%, $1.7B). Advertising grew 26%. AWS's ~21% of revenue produced roughly 60% of company operating income — the mix that makes AWS the number that matters.

Now the line to discard. Reported net income was $62.6B, or $5.75 per diluted share — versus $18.2B and $1.68 a year ago — but that figure is not comparable: net income included a $53.4B gain, "primarily from our investments in Anthropic," a non-operating mark-to-market that flows through the income statement without touching the business. Strip it out and the quarter is the 43% operating-income growth, not the ~$5.75 headline. (For scale on the markup: Amazon holds a ~21% Anthropic stake carried near $74B at the end of Q1; Anthropic's confidential IPO filing is reported to value the company around $965B, which would mark Amazon's position toward ~$200B — the source of the gain, and unverified beyond the disclosed $53.4B line.) The cash statement is the honest counterweight: trailing-twelve-month purchases of property and equipment reached $169.0B, up $66.1B (+64%) year-over-year, operating cash flow was $161.4B (+33%), and trailing free cash flow turned negative at −$7.6B (from +$18.2B). The demand line and the cash line are both records of the same build, pointed opposite ways.
