Massive increases in demand due to this stuff being really really useful can cause prices to go up even for existing chips (NVIDIA is basically printing money as they can sell all they can make at for as much money as the buyers can get from the investors). I have vague memories of something like this happening with RAM in the late 90s, but perhaps it was just Mac RAM because the Apple market was always its own weird oddity (the Performa 5200 I bought around then was also available in the second hand listings on one of the magazines for twice what I paid for it).
Likewise prices can go up from global trade wars, e.g. like Trump wants for profit and Biden wants specifically to limit access to compute because AI may be risky.
Likewise hot wars right where the chips are being made, say if North Korea starts fighting South Korea again, or if China goes for Taiwan.
