Nvidia’s grip on the lucrative AI-chip market is facing fresh tests as major customers move to diversify away from its hardware. Amazon is accelerating plans to run more of its in-house AI models on proprietary Trainium and Inferentia chips, aiming to cut computing costs and ease dependence on Nvidia accelerators that are powerful but expensive and supply-constrained.

While Amazon is not dropping Nvidia overnight, its shift highlights how hyperscalers are prioritizing tighter control over AI infrastructure and long-term margins. At the same time, Intel is teaming with SambaNova on a full-stack AI solution that positions itself as an alternative to Nvidia, underscoring a broadening competitive field that investors in Nvidia stock must watch closely as AI capital spending soars into the hundreds of billions of dollars.
