CMLL announced that current CMLL World Heavyweight champion Claudio Castagnoli has signed a contract with the promotion, with the Swiss Superman now under a dual contract with AEW as well.

While AEW has announced multiple CMLL stars as under dual AEW/CMLL contracts, Castagnoli is the first from AEW to be under a similar dual deal.

The Death Riders member has been CMLL World Heavyweight champion since November 28, 2025, beating Gran Guerrero at the Leyenda Azul event in Mexico City. It’s his first run with any CMLL title.

CMLL’s Mistico, Mascara Dorada, Hechicero, and Persephone also have dual contracts.
