Amazon's second quarter of 2026 is the moment the multi-year thesis on this company finally broke from "AWS is mature" to "AWS is reaccelerating and Amazon is the only hyperscaler that also runs a real retail and advertising machine." Net sales rose 20% to $200.6 billion, operating income climbed 43% to $27.5 billion, and AWS grew 37% - its fastest quarter in 18 quarters - pulling the cloud business to a roughly $169 billion annualized revenue run rate. The single most important observation is that the AWS reacceleration is no longer theoretical: it is showing up in segment growth, in operating income dollar growth, and in the speed at which the AI and chip businesses are scaling inside it.
The mechanism is straightforward and tightly linked. AWS is selling more AI infrastructure to more kinds of customers, and Amazon is selling more of its own silicon (Trainium and Graviton) and more of its own frontier-model platform (Bedrock) to those same customers. Management disclosed this quarter that AWS's AI business and its chip business each crossed $25 billion in annualized run rate, both growing at triple-digit year-over-year percentages. The combination of hyperscale customer wins - Anthropic and OpenAI both signed multi-year, multi-gigawatt Trainium commitments - plus a Graviton5 launch and a Bedrock catalog that now includes OpenAI's GPT-5.6, Anthropic's Claude Opus 5, Google's Gemma 4, and xAI's Grok 4.3 turns AWS from a capacity seller into a vertically integrated AI platform. The retail and advertising business underneath is doing the rest, with advertising growing 26% and third-party seller services up 16%, and the Anthropic mark-to-market alone added $53.4 billion of pre-tax non-operating other income this quarter, which is how net income landed at $62.6 billion, or $5.75 per diluted share, against $18.2 billion, or $1.68, a year ago.
The single load-bearing risk is that the same capital expenditure line that is making this story work is also producing the worst free-cash-flow print in the company's recent history: trailing-twelve-month free cash flow swung from a $18.2 billion inflow a year ago to a $7.6 billion outflow, driven by a $66.1 billion year-over-year increase in property and equipment purchases tied to AI infrastructure. Operating cash flow over the same period grew 33% to $161.4 billion, so the cash engine is intact, but the equity is being asked to underwrite a multi-year capex cycle before the AI revenue fully scales into the income statement. The next data point that tests this thesis is the third-quarter print in late October, where management has guided net sales of $197 to $202 billion (9% to 12% growth) and operating income of $22.5 to $26.5 billion; the variable the market is watching is whether the AWS growth rate holds above 30% and whether free cash flow stabilizes rather than deteriorating further.
