Amazon's AWS Growth Surges, AI Chip Business Scales

What happened

Amazon reported a standout Q1, with AWS revenue accelerating to 28% year-over-year growth, well above the 24% exit rate in Q4 2025, driven by enterprise cloud demand and hyperscaler agreements. The in-house AI chip business achieved a $20 billion annual run-rate with triple-digit growth, surpassing the prior estimate of >$10 billion, positioning Amazon for further data center market leadership. AWS operating margins expanded to 23%, signaling that the massive capex cycle is beginning to yield improving returns on invested capacity. While capital expenditures remain elevated, the strong revenue conversion and custom silicon adoption support the bull case of the DeepValue report, where AWS sustains >20% growth. The results validate the thesis that Amazon's AI infrastructure build is monetizing faster than previously feared, though the long-term test remains whether growth can sustain as capacity continues to ramp.

Implication

The Q1 beat strengthens the bull case's dominant driver: AWS growth above 22% for two consecutive quarters, with conversion of ~$244B performance obligations accelerating. Investors should expect near-term upside toward the master report's $250 base case, but remain wary of capex sustainability. The key risk now becomes whether this pace can hold as comps become more difficult and whether power constraints will limit capacity delivery in H2 2026. Re-assess at Q2 results for signs of sustained momentum; if growth stays above 22%, the attractive entry around $200 has passed, but the stock remains a potential buy below $220.

Thesis delta

The Q1 results confirm the bull scenario in the master report, with AWS growth accelerating to 28% (above the 24% Q4 rate) and custom silicon run-rate doubling to $20B. This reduces the probability of the bear case (25%) and increases conviction that the AI infrastructure spend is generating faster-than-expected returns. The near-term catalyst is now the Q2 report to see if growth stabilizes; the thesis shifts from 'wait for proof' to 'buy on dips given growth visibility'.
