Sinaloa Cartel

CONFIRMED: Emerged from the breakup of the Guadalajara Cartel in the 1980s under Joaquín "El Chapo" Guzmán and Ismael "El Mayo" Zambada. CONFIRMED: Ovidio Guzmán was arrested in Mexico in January 2023 and extradited to the U.S. in September 2023. El Mayo and Joaquín Guzmán López were taken into U.S. custody in July 2024. The Chapitos-Mayiza war began in September 2024. El Mayo pleaded guilty in August 2025 and was sentenced on July 20, 2026 to life without parole plus a $15 billion forfeiture by Judge Brian Cogan in Brooklyn federal court. Joaquín Guzmán López pleaded guilty in December 2025.

ASSESSED: Preserve trafficking revenue and precursor access; defeat the rival faction; keep the political and security protection that lets the cartel operate.

None. Profit-driven criminal enterprise.

Federated trafficking enterprise with negotiated territorial arrangements, now broken into rival factions.

REPORTED: Culiacán is the core command center. Border plazas in the Tijuana-Mexicali area and Sonora feed U.S. distribution. Cell-level structure beneath the two factions is not publicly mapped (DATA DEFICIT).

Industrial-scale production of methamphetamine and fentanyl in Sinaloa, Durango and Chihuahua; cross-border trafficking through ports of entry; taxation of other criminal networks; targeted killings and forced disappearances in the home territory.

CONFIRMED: Chapitos-Mayiza fighting in Sinaloa since September 2024, including Culiacán. CONFIRMED: October 16, 2026 arrests of seven people in Sinaloa, including four relatives of a cell leader tied to the Mayiza, whom U.S. authorities say traffics fentanyl, methamphetamine and cocaine and supplies weapons and manpower.

Cártel de Jalisco Nueva Generación (primary rival); Mexican armed forces and National Guard; U.S. DEA and FBI; the rival Sinaloa faction.

DATA DEFICIT

DATA DEFICIT: We found no sourced operational link between the Sinaloa Cartel and any terrorist group. The FTO designation is a legal tool, not evidence of a terror partnership. Any link will be added to this profile only when sourced.

ASSESSED: A paramilitary capability built around small units, long arms and vehicle-mounted weapons in the home territory, plus commercial drones for surveillance and attack. We do not publish technical specifics.

Sierra Madre Occidental mountains, Pacific coastline and ports, border cities and a large road network.

REPORTED: Use of encrypted messaging and digital payment methods, including cryptocurrency, for settlement. Scale is not independently measured (DATA DEFICIT).

DATA DEFICIT: Plaza-level controllers are not publicly mapped.

ASSESSED: Production, transport, wholesale distribution into the United States, and laundering of proceeds.

DATA DEFICIT: Locations are not publicly confirmed.

Two rival command tables: the Chapitos and the Mayiza.

CONFIRMED: U.S. federal prosecutions in Brooklyn and other districts; El Mayo's life sentence (July 20, 2026); guilty pleas by Ovidio and Joaquín Guzmán López.

Dependence on imported precursor chemicals reaching Pacific ports.

Joint cargo screening, chemical anomaly tracking and supplier prosecutions.

Laundering through trade-based schemes, real estate and cryptocurrency exchanges.

Beneficial-ownership disclosure, financial sanctions and cryptocurrency tracing.

The faction war and the loss of the founding generation leave the Chapitos and the Mayiza exposed to arrest and defection.

Pursue the remaining fugitive leaders and the officials accused of protecting them, while expecting more fragmentation.

Precursor-chemical interdiction at ports and with Chinese and Indian suppliers; beneficial-ownership checks on front companies; sanctions and blockchain tracing against laundering networks; pressure on political protection networks; capture of faction leaders.

5 - Critical (Transnational/Multi-Theater)

ASSESSED: Extreme. The cartel supplies a large share of U.S. illicit fentanyl and methamphetamine and holds territory in Mexico by force.

4 - High (Advanced SALW/Thermal Optics/Coordinated Ambushes)

ASSESSED: High inside its home territory, limited elsewhere.

5 - Critical (State-Permissive Sanctuary/Deep Financial Infrastructure)

ASSESSED: High. The faction split and the founders’ removal have not stopped production or export.

4 - High (Centralized Media Wing/Multi-Lingual High-HD Video)

ASSESSED: Moderate to high. Uses public messages, local patronage and fear to shape local behavior.

ASSESSED: El Mayo’s sentence ends the founding-generation model, but analysts expect it will not end the faction war. Expect more splintering under U.S. and Mexican pressure.
