Anthropic and Amazon announced a significant expansion of their partnership to secure up to 5 gigawatts (GW) of capacity to train and run Claude. Why does that sound like a lot? Because behind that number are big investments, large-scale chips, and a bet on keeping things fast and reliable as demand grows.

What was announced

The collaboration between Anthropic and Amazon deepens with an agreement that guarantees up to 5 GW of new capacity to train and run Claude. The plan includes the arrival of Trainium2 in the first half of the year and almost 1 GW total of Trainium2 and Trainium3 before the end of 2026.

Anthropic has already been working with Amazon since 2023: more than 100,000 customers use Claude on Amazon Bedrock, and together they launched Project Rainier, one of the largest compute clusters in the world.

Why it matters
