Positioning

Anthropic is a U.S. public benefit corporation developing Claude and operating as a frontier-model compute buyer rather than an owner-operator of large data-center sites. It signed agreements in 2025-26 for up to 5 GW of Amazon Trainium capacity, about 5 GW of next-generation Google/Broadcom TPU capacity, and GPU capacity from SpaceX, while making Claude available through AWS, Google Cloud, and Microsoft Azure. Its distinguishing position is diversified access to multiple hyperscaler and neocloud platforms; the open question is how much of its announced capacity is energized and operational rather than contracted.
