Why would they be subjected to anti-trust? There's a robust competition from AMD and Intel, and NVidia is not using any obviously illegal competition tricks.
Idk how you're defining "robust competition", but NVIDIA and CUDA definitely rule the GPU computing space right now, at least judging from a biased sample of what I read online. Those who experienced computing in the 1990s and 2000s know of the harmful effects that result when proprietary tech stacks become de facto monopolies. Think Adobe Flash, think Microsoft's "embrace/extend/extinguish" strategy. Perhaps antitrust law needs rework if it can't deal with this kind of monopoly.
