I guess it’s really from 4chan but I found it on r*ddit
There are currently around 70 million $GME shares in existence, at 250% shorted, that puts us at 175 million shorts. To be conservative, and for simplicities sake, lets round that up to 200 million.
Bank of America has total assets equalling 2.34 trillion.
Even if Bank of America had assumed all of the risk (which it hasn’t) for GME shorts to bankrupt just them $GME would need to reach a value of $10,000 per share.
Unless we start seeing $GME values pushing well into the tens thousands I don’t think there’s any chance this short squeeze can cause a financial collapse as described in that post.
That being said, Bank of America only has “operating revenue” (cash on hand) in the tens of billions, so $GME pushing past $1,000 would force banks to liquidate their other assets which could very well have a run on effect on the economy.
