It appears that AEW will soon be available on a US streaming service, either through their own platform or by licencing their streaming rights to a service, as WWE did with Peacock for a significant fee.
The history of AEW, which debuted in 2019, is covered in an article by Bloomberg with AEW President Tony Khan. In the article, they note that AEW are considering streaming service, likely through Warner Bros. Discovery:
“In March, Khan acquired the small but respected pro wrestling company Ring of Honor from Sinclair Broadcast Group Inc. for an undisclosed sum, adding a new crop of wrestlers, some intellectual property and an extensive video library. AEW is also considering starting a streaming service, likely through a deal with its broadcast partner, Warner Bros. Discovery Inc., according to a person familiar with management’s thinking, who asked not to be named. Last year, AEW broke $100 million in annual revenue for the first time, the person says.”– Bloomberg
A television agreement between AEW and Warner Bros. Discovery allows for the broadcast of AEW Dynamite on TBS on Wednesdays and AEW Rampage on TNT on Fridays. YouTube currently hosts AEW Dark and AEW Dark: Elevation. Traditional pay-per-view and B/R Live both broadcast pay-per-view events in the US.
