IMO, here is an unlikely, but worst possible scenario for your calls, based on your assumption that the calls will be exercised if S&P inclusion is announced:
1. S&P Inclusion announced, your calls exercise. You are ecstatic to be on the hook for $9mil worth of stock valued at... $10mil
2. Over the weekend, Elon Musk's FSD prototype Tesla drives off a cliff. His body is nowhere to be found.
3. Monday morning, due to events of the weekend, TSLA stock drops to $200. You have $4mil worth of stock, and owe $9mil worth based on Friday call execution
