If I sold GME $300 naked call and get assigned, and the broker doesn't have any shares available to borrow, what happens? If the shares are available to borrow, I will be short 100 shares of GME when assigned. But I'm not sure what happens when broker doesn't have any shares to lend me. Will I be sued by the broker or the call holder? I know selling naked calls is risky but I'm ok with that as long as GME doesn't cross $3000.
