Mexico's drug war in 2026 is dominated by two super-cartels locked in a nationwide fight: the Jalisco New Generation Cartel (CJNG) and the fractured Sinaloa Cartel. Between them they drive most of the country's organized-crime violence — and the map shifted sharply in February 2026, when CJNG founder Nemesio "El Mencho" Oseguera was killed by the Mexican army in Jalisco, triggering a wave of coordinated attacks. This is a plain-language map of who controls what, state by state, as of 2026.
Cartel territory is fluid and contested, not neatly drawn — but the broad picture below reflects the dominant force in each region. Track the situation live on the ConflictZone.io map, and see the full Mexico drug cartel war breakdown.
The Two Dominant Cartels in 2026
CJNG — the most powerful cartel
The Jalisco New Generation Cartel is considered by the Mexican government the country's most powerful and dangerous criminal organization. From its heartland in Jalisco, it has pushed into Michoacán, Guanajuato, Colima, Veracruz, Zacatecas, Guerrero, Baja California and beyond. Its long-time leader "El Mencho" was killed on 22 February 2026, and the succession struggle since has made CJNG both aggressive and unstable.
Sinaloa Cartel — fractured and at war with itself
Once a near-monopoly over Sinaloa state, the Sinaloa Cartel split after the 2024 capture of its leaders into two warring factions: "Los Chapitos" (the sons of Joaquín "El Chapo" Guzmán, centred in central Sinaloa) and "Los Mayos" (loyalists of Ismael "El Mayo" Zambada, centred in western Sinaloa). Their internal war has turned the cartel's home state into a battleground and weakened it against CJNG.
Cartel Control by Region (2026)
- Jalisco, Colima, Nayarit — CJNG heartland.
- Sinaloa — a war zone: Los Chapitos (central) vs Los Mayos (west), with CJNG probing from outside.
- Sonora, Durango, Chihuahua — the "Golden Triangle," historic Sinaloa Cartel opium/meth country, now contested amid the infighting.
- Michoacán — CJNG vs the local self-defense alliance Cárteles Unidos.
- Guanajuato — CJNG against the remnants of the Santa Rosa de Lima cartel; one of Mexico's most violent states.
- Zacatecas & Guerrero — open CJNG–Sinaloa battlegrounds over trafficking corridors; among the deadliest.
- Tamaulipas & Nuevo León — Gulf Cartel and the Northeast Cartel (CDN) dominate the border northeast.
- Baja California / Quintana Roo / Veracruz — contested plazas where CJNG and Sinaloa-aligned groups fight over ports, tourism corridors and smuggling routes.

The Deadliest Flashpoints
Most of Mexico's cartel homicides in 2026 cluster where CJNG and the Sinaloa factions collide over drug-trafficking corridors — above all Zacatecas, Michoacán and Guerrero, plus Sinaloa itself during the Chapitos–Mayos war and Guanajuato's grinding local conflict. The killing of El Mencho in February 2026 added a fresh layer of instability as CJNG's rivals tested its cohesion.
