I haven't read anything about a potential government bail-out of the various hedge funds, including Melvin Capital. Melvin Capital (and perhaps some other hedge funds) have received infusions of capital from other hedge funds (Steve Cohen-Point 72 Capital - and the new owner of the NY Mets and Ken Griffin - multi-billionaire hedge fund "guy" and investment firm owner, because Melvin Capital has apparently lost a ton of money on its GME shorts (and perhaps other shorts too). I think the real issue is how leveraged Melvin Capital is (i.e., how much money they have borrowed from banks to invest along side their own and investor capital - many hedge funds use leverage to boost their potential gains) and whether or not their losses on the short positions put those loans from banks at risk (and thus posing a systematic risk to the entire banking system). Something similar happened in 1998 when a CT-based hedge fund - Long-Term Capital Management - suffered huge losses when a trading strategy suddenly went awry and the lost vast amounts of money very rapidly. The firm had, I believe, a 28 to 1 leverage ratio (i.e, if they had $1 billion of their own and investor capital in the firm, they then borrowed $28 billion from outside banks to invest). Their losses were so huge that they could not re-pay the bank the full amount of their loans and, for a short time, it was a very scary situation (and not completely well publicized) for the entire international banking system.

Let's hope this is not the case here but it does raise the issues of better and smarter regulation of the securities markets and the participants, including hedge funds and other institutional investors (should we allow 150% of a stock's outstanding float to be shorted?) AND some of the more lunatic fringe element of the "day traders" that have popped up on Reddit and Robin Hood and who are causing huge dislocations to the normal functions of the financial markets.
