In a dramatic move that could alter the global drug trade, a faction of the Sinaloa Cartel led by El Chapo’s sons has formed a covert alliance with their long-time enemy, the Jalisco New Generation Cartel. This unexpected truce, forged in desperation after months of war and external pressure, could usher in a new era of dominance for CJNG — and ignite fresh violence across Mexico and beyond.

Desperation Breeds an Unthinkable Pact

The once-dominant Sinaloa Cartel, for years a global powerhouse in fentanyl trafficking, has fractured under the weight of internal divisions and relentless attacks from U.S. and Mexican authorities. The most dramatic consequence: an unprecedented alliance between the cartel’s Los Chapitos faction — led by the sons of Joaquín “El Chapo” Guzmán — and the rival Jalisco New Generation Cartel, known for its militarized tactics and ambitions of supremacy.

According to four individuals with direct knowledge — including two high-level Sinaloa operatives — the alliance emerged from sheer necessity. “Los Chapitos were gasping for air, they couldn’t take the pressure anymore,” said one cartel figure. “Imagine how many millions you burn through in a war every day: the fighters, the weapons, the vehicles.”

From Betrayal to Bloodshed: How the War Began

The internal rupture began when Joaquín Guzmán López, one of the Chapitos, betrayed his father’s longtime partner Ismael “El Mayo” Zambada by kidnapping him and handing him over to U.S. federal agents last summer. That betrayal detonated a bloody feud between the two factions — Zambada’s old guard and the younger, ambitious Chapitos.

The result: more than 1,300 people dead and over 1,500 missing in Sinaloa alone. Entire neighborhoods in cities like Culiacán emptied as residents fled daily shootouts and cartel executions. One afternoon this month, a father and son were ambushed in traffic, their vehicle struck by over 50 rounds. A fruit vendor selling drinks nearby whispered, “My hands are trembling. I don’t want to sell like this.”

High Stakes Negotiations With Global Consequences

To escape their weakening position, the Chapitos initiated talks with CJNG, offering territory in exchange for arms, cash, and protection. The discussions took months, often taking place in neutral zones outside contested areas — even outside Mexico. “It’s like if the U.S. and China need to reach a deal,” said one cartel insider. “Neither side wants to go to the other’s turf.”

The alliance is a strategic jackpot for CJNG. It gives them access to the Chapitos’ fentanyl production expertise, international trafficking routes, and financial infrastructure — an outcome analysts say could vault the Jalisco group to unprecedented power.

“It’s like bringing Messi to your football team,” said Eduardo Guerrero, a veteran Mexican security analyst. “Combining both forces will mean having an enormous global production capacity.”

Crackdowns Fuel Chaos, Not Control

The alliance has been catalyzed by intensifying enforcement. Under pressure from the Trump administration, Mexican forces have flooded Sinaloa with troops, raiding labs and making high-profile arrests. The U.S. boasts a 30% drop in fentanyl seizures at the border. But experts caution that these tactics may only be forcing traffickers to adapt, not retreat.

“They’ve just shifted production to other states,” said one cartel operative. “The heat in Sinaloa is too much now.”

Retired U.S. diplomat John Creamer echoed the frustration of decades-long anti-drug policy: “You can never truly put a stake through the heart of an entire cartel. The drug trade always bounces back. That’s what makes this war so frustrating.”

A New Narco Order — and More Violence Ahead?

While the cartel merger may offer temporary gains for both sides, it could also trigger wider warfare. Smaller groups like the Gulf Cartel, Northeast Cartel, and local self-defense forces may resist the new configuration, leading to violent realignments in Michoacán, Jalisco, Sonora, and beyond.

In Culiacán, murals of the disappeared line the streets, and forensics teams pull tortured bodies from cars as families wail in grief. Even in the shadows of this trauma, some residents profit from the violence, selling refreshments at murder scenes. “It was the first good day in months,” said a lemonade vendor, “but I didn’t want it to be like this.”

The Mexican criminal underworld is entering a volatile new chapter. What began as a local feud between El Chapo’s heirs and an aging kingpin may soon reshape organized crime networks from Bogotá to Bangkok. Whether this cartel super-merger brings dominance or implosion, one truth endures: Mexico’s narco war remains far from over.
