Amazon Explores Selling Trainium AI Accelerators to Third-Party Data Centers
Hyperscalers' custom silicon moves toward merchant availability, as surging demand drives South Korea's memory chip exports to new highs.
The story
Amazon is reportedly in early discussions to sell its custom Trainium AI accelerators directly to third-party data centers, a significant departure from its decade-long AWS-exclusive distribution model. This strategic shift, reported on June 18, 2026, marks the first time Amazon silicon, specifically the Trainium3, has reached rack-scale performance comparable to Nvidia's Blackwell NVL72, according to third-party analysis.
The company's internal custom-silicon division reportedly achieved a ~$20 billion annual run rate in Q1 2026, with CEO Andy Jassy estimating a standalone chip business could reach ~$50 billion annually. This move mirrors a broader trend among hyperscalers, as Google Cloud has also begun selling its custom TPUs to select customers, projecting 4.3 million TPU shipments in 2026. Custom ASIC shipments are projected to grow 44.6% year-over-year in 2026, nearly triple the 16.1% growth for merchant GPUs, indicating a rapidly expanding market where custom silicon is gaining significant traction.
Silicon
Trainium3
Maker: Amazon
What: AI accelerator, reaching rack-scale performance comparable to Nvidia's Blackwell NVL72.
For Whom: Potentially third-party data centers, in addition to AWS.
Supply & policy signals
South Korea's memory semiconductor exports exceeded $23 billion as of June 20, 2026, with June projected to reach $38 billion to $42 billion, a new record.
Implication: Strong AI-related demand and ongoing supply shortages for HBM3E and HBM4 are driving up export values and unit prices, tightening general-purpose DRAM supply.
