AWS Q2 Revenue Hits $42.2B (+37% YoY), Fastest Growth in 18 Quarters; Capacity 'Spoken For' Through 2028

AWS posted $42.2 billion in Q2 revenue, up 37% year-over-year — its fastest growth in 18 quarters, since late 2021 — decisively answering skeptics who had questioned whether the AI buildout was translating into cloud revenue. CEO Matt Garman told analysts that much of AWS's capacity is 'spoken for through 2027 and into 2028,' a striking statement of demand that sent, per one outlet, 'shivers down the spines of AI bears.'

The internal composition is telling: AWS's AI and Chips businesses each eclipsed $25 billion run rates while growing at triple-digit rates, indicating the growth is genuinely AI-driven rather than legacy cloud. The 'spoken for through 2028' framing reinforces the week's dominant compute-scarcity theme — the constraint on the industry is increasingly physical capacity, not demand or model quality.

AWS paired the results with aggressive pricing: it cut on-demand inference prices for OpenAI's GPT-5.6 Luna 80% on Amazon Bedrock effective July 30, mirroring OpenAI's own 80% cut and extending the price compression now sweeping the market from both the open-weight Chinese labs and the hyperscalers hosting closed models.

Context for readers: this is the demand side of the same story Anthropic's $10B Volta deal tells from the supply side. When the largest cloud provider says it is sold out two years forward, it validates the enormous capex commitments across the industry — but also raises the question of whether capacity constraints will throttle the pace of AI deployment through 2027. The bull case is that AWS's numbers prove durable, monetizable demand; the bear caveat is that 'spoken for' bookings can soften if the broader AI ROI narrative wobbles. Amazon's own agentic push on Bedrock — including new partnerships like Superblocks' multi-year collaboration — is designed to keep that demand sticky.
