When WWE finally returns either in the fall or early next year.
I've searched pretty thoroughly, and while there's a lot of speculation that WWE will no longer be holding any shows after WrestleMania, they haven't made any announcement to that effect.
It just seems like so many people and websites are incorrectly assuming that WWE & AEW (or any other wrestling company for that matter) will be forced to shut down due to the stay-at-home order.
I get that professional wrestling doesn't, at first glance, seem like it would be considered an essential business, but if you read the actual order (link below), WWE falls into 2 of the categories that are exempt from the order. One provision allows for essentially any form of media to continue to do business. Another exception allows for any company not doing business with customers face-to-face.
Any of the businesses that fall under the huge list of exceptions aren't even required by law to comply with the 10 people/6 feet limitations. They're strongly encouraged to do so, but not required by law.
I'm not saying wrestling companies won't decide to shut down, but there's nothing legally preventing them from continuing to do the shows as they have been.
