Nvidia’s dominance rests on CUDA, not just its chips. AI coding agents and the shift to inference are the first credible threats to that software moat.

Nvidia has long dominated because of its CUDA software. Now, AI-driven software is challenging this moat as startups and giants innovate.

An AI startup says it recreated Nvidia's CUDA-like software in 10 hours, raising questions about the chipmaker's AI moat.
