It worked, Gamestop postmarket price is down from market close.
Further, I think everyone is drastically over estimating the impact of r/wsb and retail investors in general on the GME action. This is hedge fund vs. hedge fund in an opportunity for unusually outsized gains on both the long and short positions over relatively short time frames. Good for them to keep the narrative focused on retail investors rather than capitalist titans in a financial blood bath.
If you don't see this, then you don't know if these people are still your allies.
