If it causes "no liquidity" in the open market because nvidia (tsmc) can only produce so many GPUs / month and that causes nvidia's other cards to have a street price of 2x MSRP due to lack of availability? I would say yes.. It's just that "H100" or "RTX 5090" is not a registered stock with the SEC, so there aren't specific laws / penalties for manipulating the GPU market.
Same as "10 per store" limits when PS5s or whatever are in short supply, but then the CEO calls up the warehouse to get one for every student in their kid's class.
