I don't think anybody in their right mind would ever bailout Anthropic or Nvidia.
Now bailing out somebody who over-invested in Nvidia but also holds the world's retirement savings... now that's something I can believe.
There is zero reason to bailout either. Force a sale of assets to a US-based company? Sure. But no need to bail out. The US has the first second and third best GPU companies and the best five AI companies. Unless they all go under simultaneously then I see zero incentive to bailout.
