All Elite Wrestling posted a video of former long-time WWE superstar Chris Jericho singing his AEW contract with Tony Khan. 

Chris Jericho said in his debut AEW appearance at the Double or Nothing rally at TIAA Bank Field on Tuesday that he is "all in" on All Elite.

In the video, Chris Jericho says he's in AEW for "the long haul." 

Shad Khan and his son, Tony, unveiled the new professional wrestling organization on the same day WWE Smackdown was in Jacksonville.

Their shared vision is to “launch with a roster of the top wrestlers in the world” — seemingly to compete with the World Wrestling Entertainment juggernaut. Initially, they will partner with former WWE star Cody Rhodes and several others who form a group known as “The Elite.”

It’s unclear exactly how much Shad Khan will invest in the project, but the initial response from industry insiders seems to be one of optimism for AEW, which would benefit from striking a TV deal.

A rally for AEW’s inaugural event, dubbed “Double or Nothing,” was held 5 p.m. Tuesday in Lot J next to TIAA Bank Field. It was free and open to the public.
