It is impossible to overstate how risky options are in this situation.

The implied volatility for NVDA is astronomical. Put differently, the OP isn't the first one with the idea to short them, so this incredible demand for options drives the premiums up substantially.

That stack of (temporary) paper you are paying for is likely way more expensive than you think it is.

Shorts I think are only useful if there is an imminent and concrete devaluation event such as defaulting on credit etc. A general predicted market downturn is hard to tie to stock behavior, especially within a concrete time frame.
