If you imagine it like making a bet, nobody’s going to take a bet with you where they pay you when it pops, but there’s no time after which you pay them – because they’d never get any money out of that bet. Buying stock is different because it’s a thing you can own, but you can’t invest in the idea of something failing, because there isn’t any business which will take your money and make something more likely to fail.

You could buy every stock except AI-related stocks, which I believe is functionally equivalent to buying an index fund and shorting AI stocks based on the percentage of AI stocks in the index fund. You could also think about what businesses would do well (or less poorly) in the case of an AI-instigated crash, and then buy those.
