Amazon’s AI Spending Keeps Rising. Andy Jassy Says Memory Costs Drove $20 Billion Capex Increase.
Amazon said it expects 2026 cash capex of about $220 billion, up from a prior estimate of about $200 billion, citing higher AI memory chip costs, according to CEO Andy Jassy on the Q2 earnings call. Jassy also said capacity may still fall short of demand in 2026-27. AWS remains the main spending focus.
How this was made

The 30-second read
Why it matters
The guidance revision is a direct read-through to AI infrastructure demand intensity and the cost structure of training and inference systems that rely on advanced memory (including HBM).
Market read
Traders can update expectations for Amazon’s 2026 infrastructure spending pace and incorporate a near-term supply constraint risk into AWS AI capacity assumptions.
What to watch
Memory cost inflation could reverse; if prices fall, the incremental capex may look conservative in hindsight, and the capacity constraint could ease with supply improvements.
Background
Amazon is expanding AI infrastructure capacity for AWS workloads, and management attributes the capex increase specifically to higher memory costs.
Ticker impact
Amazon raised 2026 cash capex guidance to about $220B from ~$200B, citing higher AI memory chip costs and capacity constraints.
Near-term sentiment likely mildly positive for AI infrastructure demand, but tempered by the explicit capacity shortfall risk.
The article contains a fresh, attributable capex guidance revision and a forward-looking capacity constraint statement, both directly tied to Amazon’s AI infrastructure buildout.
Market effects
Signals continued hyperscaler willingness to pay premium for HBM/advanced memory, reinforcing AI infrastructure spend intensity.
No specific regional market impact beyond global AI supply chain demand.
Supports the broader global AI capex cycle and memory pricing power narrative.
Counterpoint
The capex increase may not translate into incremental revenue if demand outstrips supply, potentially pressuring near-term margins or delaying customer fulfillment.
