There is no naked shorts here. The short interest went above 100% simply because the same shares were lent out more than once.
A holds 100 shares of GME. B borrows the 100 shares & sells them short to C (Who is actually a buyer). D borrows the 100 shares from C and sells them short to E (Who is actually another buyer). Here you go, the same 100 shares were lent twice & shorted twice.
When you look at the short interest, it will show 200 shares short while in reality only 100 shares exist. If all the outstanding shares are those 100, then you have a short interest of 200% of the outstanding.
In such a cycle, there are 3 different owners, A (The original owner), C and E, each is supposed to own a 100 shares. But there is only a 100 shares available, so how can this happen?
It's because it's all artificial. These A, C & E shareholders are only shareholders on paper. Since there are 200 shares short outside, it created 2 artificial owners.
If the shorts want to cover, they must find a seller and to cover 200 shares short, you need any 2 of the 3 owners to sell their 200 shares, once this happens, the extra 200 shares disappear (Gets offset) and you are left with only 1 owner having the original 100 shares.
It's very similar to how option contracts are created, except it doesn't have any expiry & there is some original number of outstanding shares there.
Another question, if the company pays dividends, where will the company come with money to pay dividends to the other 200 artificial shares? The answer is they won't. The shorts will pay the dividend (As a cost to their short position) to the 200 shares owners, while the company will only be responsible to pay the dividend to the original 100 shares.
This is not naked shorting. Naked shorting is actually selling short shares where there is no locates. This is not the case here, everytime a short seller in our case sold shares short, there was a locate and a lender willing to lend the shares (Because the shares are residing in his margin account and are shortable).
