AMD secures $5B AI-chip deal with Anthropic, intensifying competitive threat to Nvidia

AMD announced a $5B deal with Anthropic for 2GW of MI450 chips, with ROCm gaining traction at Microsoft, OpenAI, Oracle, and Meta. This is a direct competitive threat to Nvidia's GPU dominance and CUDA moat. The deal shows Anthropic diversifying away from Nvidia, signaling potential market share erosion. AMD's software ecosystem is improving, challenging Nvidia's lock-in. At AMD's Advancing AI event, Helios racks and MI455 GPU were unveiled, and ROCm progress with OpenAI deployment was highlighted, further eroding Nvidia's software moat.
