If you short gme you're about to be in very heavy debt to your broker. At least buy a put or something instead.

I don't think anyone is actually long on gamestop at $350 per share, but trying to short is not about company expectations at this point, it's about timing this hysteria wave, and if you mistime it you get destroyed by infinite risk and your broker liquidate your position and you leave with not 10k, but -100k.
