Amazon Weighs Selling Its Trainium AI Chips to Outside Customers — and Taking On Nvidia
AWS is in early-stage talks to sell its in-house Trainium AI chips to outside customers for the first time — a direct challenge to Nvidia's dominance, confirmed by AWS AI chief Peter DeSantis in June 2026.
TL;DR — On June 18, 2026, AWS confirmed it's in early-stage talks to sell its custom Trainium AI chips to outside customers for the first time — a strategic reversal aimed directly at Nvidia, which has long owned the market for AI training silicon.
Amazon has built its own AI chips for years, but kept them inside AWS. That may be about to change. On June 18, 2026, the company said it's exploring letting other organizations buy or rent Trainium — a shot across Nvidia's bow.
What Amazon confirmed
AWS AI chief Peter DeSantis told Bloomberg the company is in talks to make Trainium available to other companies for their own data centers, declining to name customers; AWS separately called the discussions "early-stage." CEO Andy Jassy had hinted in Amazon's April 2026 shareholder letter that selling chips to third parties is "quite possible."
Who already runs on Trainium
| Trainium customer | Scale |
|---|---|
| Anthropic (Project Rainier) | ~500,000 Trainium2 chips; up to 5 GW committed |
| OpenAI | ~2 GW reported |
| External buyers | None yet — talks are "early-stage" |
Anthropic is the anchor customer, running roughly 500,000 Trainium2 chips in its "Project Rainier" cluster, with up to 5 gigawatts committed; OpenAI has reportedly secured about 2 GW. The catch: Trainium3 (shipping since early 2026) is "largely sold out," so external sales hinge on expanding production.
Why it rattles Nvidia
This is Amazon moving from cloud-only to merchant chipmaker. Jassy noted that if Amazon's chip business "was a standalone business… our annual run rate would be ~$50 billion." For scale, TechCrunch cited Nvidia's comparable run rate near $326 billion — so Amazon is still a challenger, not a peer. Markets liked it: Amazon shares rose as much as 2.5% on the news.
Asked whether external sales would cannibalize AWS's own cloud business, DeSantis was unbothered: "There's so much underconsumption in AI. I'm not worried about it."
FAQ
Is Amazon actually going to sell Trainium chips externally?
It's in early-stage talks, confirmed by AWS AI chief Peter DeSantis on June 18, 2026. No external customers are named yet, and nothing is finalized.
Why would this worry Nvidia?
Nvidia dominates AI training silicon. If AWS sells Trainium to outside data centers, it gives big AI buyers a cheaper, alternative supplier — directly targeting Nvidia's customer base.
Who uses Trainium today?
Mainly Anthropic (~500,000 Trainium2 chips in Project Rainier, up to 5 GW) and reportedly OpenAI (~2 GW) — but as internal AWS customers, not third-party chip buyers.
What's the catch?
Supply. Trainium3 is described as largely sold out and Trainium4 capacity is heavily reserved, so external sales depend on Amazon expanding production.
