Amazon Reportedly Plans Trainium Outside AWS as Q3 Capex Hits $75.9B

Amazon intends to make its Trainium AI chip available outside AWS beginning in late 2027, CEO Andy Jassy said on the company's Oct. 29 third-quarter call, according to a Tech Times report on the call.

Amazon's own results release, filed with the SEC the same day, does not mention the plan. It reports that AWS net sales rose 39.3% to $46.0 billion, a $184 billion annualized revenue run rate, with AWS operating income of $17.8 billion against $11.4 billion a year earlier. Amazon said it expects AWS growth of more than 40% in both 2027 and 2028, and that Trainium is now easier to adopt through TorchNeuron, which runs existing PyTorch code on the chip without rewriting it.

Tech Times also reported that customer revenue commitments for Graviton and Trainium, Amazon's two in-house chip families, grew more than 20-fold year over year, and that customers using Amazon custom silicon saved more than $2 billion in the quarter. Those are management claims, and the release does not break out Trainium revenue.

For the supply chain, the point is volume. A Trainium sold outside AWS would draw on the same foundry, packaging and memory supply as the chips Amazon installs in its own data centers, and the power and cooling for those systems would sit in the buyer's buildings rather than in Amazon's. Amazon's release lists "resource and supply volatility, including for memory chips" among the factors that could change its results.

The spending behind the chip

Amazon's cash-flow statement shows $77.3 billion of purchases of property and equipment in the quarter, against $35.1 billion in the third quarter of 2025. Tech Times put cash capex at $75.9 billion and said Amazon now expects about $220 billion for 2026. The release says the $94.8 billion year-over-year increase in trailing-twelve-month purchases, net of proceeds, primarily reflects investments in artificial intelligence.

Free cash flow for the trailing twelve months was an outflow of $42.4 billion, compared with an inflow of $14.8 billion a year earlier. Tech Times reported an AWS backlog of $578 billion. Selling chips would bring in cash when they ship, while renting the same silicon through AWS earns it back over years, which is the trade-off the capex figures put in front of investors.

Voltgrid previewed the report in its Oct. 25 week-ahead story and covered Amazon's early NVIDIA rack deliveries in an Oct. 22 report. Trainium would then compete for Amazon's own capex dollars with the NVIDIA systems it is still buying.

What is not confirmed yet

The late-2027 date is an intention stated on a call, and the plan is reported from that call by Tech Times: Amazon's release is silent on it. Nothing read so far says what form the sale would take, whether chips, boards or full racks, or at what price, to which customers, or in what volume.

DigiTimes ties the decision to TSMC capacity in its headline, but that report is behind a paywall and Amazon's release does not discuss foundry capacity, so that link stays unconfirmed. Amazon's next quarterly report should show whether the capex path and the Trainium commitments move as Jassy described.
