After my morning coffee and some snooping through 13Fs. Their put exposure was 54,000 contracts = to 5,400,000 shares; not 5,400,000 contracts, like I said it was early in the morning. Also, the value they show, $55,080,000 is just the end of Q share price not their cost. So it still looks like in the Q3 they were only paying from a couple of dimes per share to a $1; the cost was around $1,080,000 - $5,400,000. They had added another 20,000 contracts during Q4, probably as the stock was now trading at 10.They've been buying puts on GME since Q4 2015, 4,000 puts, adding or subtracting each Q. Remember, 13F only shows portfolio at quarters end, so some of their activity during that time is undisclosed. This chart shows it was it must have been a good trade going from 40s to less than 4.

It appears as GME's price rose through Dec to Jan they became more aggressive. I have found 2 trades that were probably M.C. with losses of $13 - $25 million and another $25 - $30 million. So it really wasn't WSB that brought down Melvin Capital, it was their hubris. I can't wait for the Michael Lewis book and subsequent movie.
Started writing this over 12 hours ago but got sidetracked. There's a big difference between delta hedging 5,400,000 shares and my mistake of 540,00,000 shares. An initial delta hedge of say a 30 delta put for all of M.C.'s shares would be shorting 1,620,000 shares of GME. Looking at all major holdings of GME for Q3 2020 ( you can easily spot the market makers ), there are 19,498,157 puts and 6,878 ,037 calls; again, doing the math - 30 delta put - MMs would short 5,849,447 shares in total. 13 Fs obscure more than they reveal, they don't reveal short positions or written options and you won't find strike prices or option value. Ironically, Melvin Capital by buying puts was supplying the tinder for the Great Gamma Squeeze of 2021.
