CJNG Exploits Sinaloa Cartel Fracture, Advances Into Contested Border Territories

ACLED conflict tracking data and InSight Crime analysis confirm that CJNG has accelerated territorial expansion along several fronts, exploiting the continued internal fracture of the Sinaloa Cartel following the July 2024 arrest of Ismael 'El Mayo' Zambada. CJNG fighters have launched offensives along the border of Sinaloa state, while also intensifying operations in Baja California, Zacatecas, and Chiapas. Los Chapitos — one of the warring Sinaloa factions — reportedly announced a tactical alliance with CJNG to counter El Mayo's faction. Security analysts warn that the combination of CJNG's succession crisis and the Sinaloa civil war is creating an unprecedented reorganization of Mexico's criminal landscape, with violence potentially spiking in previously stable corridors.
