Yes? Reports are that OpenAI is buying unfinished memory kits which they have no capacity to complete. It appears that OpenAI is just buying them to remove them from the market and damage their competitors. In United States, that used to be considered against the law if we were actually enforcing such things.
I doubt this is to create artificial scarcity. Especially when OpenAI is the biggest player thought to be able to build AGI first and that it is now backed by the US & the Saudis.
Since COVID, this has been the norm for any industry that requires chips.
Operation handbook now dictates that you should have 3-4 years of all the ICs you'll need for production so you don't end up like the car manufacturers.
