Probably won't happen: A network television deal
Professional wrestling has often been considered 'second tier' entertainment, meaning it might do well on cable television or, in the modern era, streaming services but it doesn't cut the mustard for the big four networks in the USA - namely NBC, CBS, ABC, and FOX.
However, that all changed when WWE and Fox network banded together to bring Smackdown to an ever larger audience. It is considered a major coup by the WWE to get their programming on as large an entity as Fox.
Don't expect All Elite Wrestling to follow suit. A fledgling wrestling promotion will still be considered quite risky. Only the WWE's long history of successful ventures made their deal with Fox possible, and many television execs will no doubt be waiting to see if AEW can survive and thrive before they even think of offering a deal.
