The main event for Double or Nothing 2026 was made official last night on Dynamite.

AEW World champion Darby Allin will defend his title against former champion MJF in a title vs hair match, where if MJF loses the match, he has to shave his hair.

The contract was signed last night after Allin successfully defended the gold against Konosuke Takeshita. After both signed the contract, MJF attacked Allin and then knocked him out with the Dynamite Diamond Ring.

MJF was about to hit a tombstone piledriver from the second rope but Kevin Knight came out to save Allin from further damage as MJF bolted.

MJF lost the title to Allin in an episode of Dynamite in April during WrestleMania week, a squash match which was super quick.
