Econ 101
Lets suppose, for the sake of argument, that the subsidies in the Chips Act truly are inefficient and that the current admin was more right than wrong in more or less abandoning those subsidies. Then the money needed generate chip production demand in the US needs to come from businesses such as current and future AI worthy domestic GPU designers (e.g. NVIDIA, AMD, Intel, Cerebras) making orders to satisfy their international customer base. As outgoing U.S. Secretary of Commerce Gina Raimondo said in 2025 "Trying to hold China back is a fool’s errand ... the only way to beat China is to stay ahead of them ... We have to run faster, out innovate them". (A truth she could only politically utter once she became a lame duck.)
So domestic GPU prices will be a little higher for Anthropic - that's still good because that higher profit margin is what drives domestic GPU designers to invest and make progress.
