Amazon hopes to challenge Nvidia more directly by selling its AI chips
1 min read
The story
Amazon Web Services is reportedly in discussions to supply its proprietary AI chips — Trainium and Inferentia — to external data center operators, moving beyond internal use for the first time. CEO Andy Jassy has sized the addressable market at $50B, and given AMZN's $716.9B revenue base growing at 12.4% YoY, even partial capture would be meaningful; however, the chip business has no disclosed revenue contribution yet and faces a long ramp from zero external traction.
Nvidia's moat remains formidable: NVDA posted 65.5% revenue growth to $215.9B with 71.1% gross margins — figures that reflect deep software lock-in via CUDA, not just hardware superiority. The key watch items are whether AWS can sign any flagship external customer to validate the $50B framing, and whether Nvidia's margins show any compression in upcoming prints as hyperscaler in-house silicon gains credibility.
The case — both sides
AMZN's $50B framing, combined with cost-sensitive data center operators seeking Nvidia alternatives, could catalyze a re-rating of AWS's silicon segment at a time when AMZN net margins (10.8%) have meaningful upside leverage from high-margin chip licensing.
Nvidia's 65.5% revenue growth and CUDA software lock-in represent a durable moat that AWS chip efforts have so far not cracked — Amazon has been building custom silicon for years with zero disclosed external revenue to show for it, making the $50B opportunity speculative at this stage.
The house read
Two-sidedThe question for AMZN and NVDA is whether AWS can convert internal chip competency into external market share that meaningfully dents Nvidia's 71% gross-margin GPU franchise.
Wrong ifNVDA re-accelerates on Blackwell demand exceeding supply, or AWS chip talks stall with no external customer signed — either outcome collapses the pair thesis.
