Sinaloa Cartel's birth: Guadalajara legacy to 1990s

In the heart of the Mexican state of Sinaloa, in the city of Culiacán, lies the epicenter of one of the world's most powerful and notorious criminal organizations: the Sinaloa Cartel. Over decades, this cartel has evolved from a local smuggling group into a transnational giant with operations in over 50 countries, known for its brutality, widespread violence, innovative methods, and remarkable ability to survive and adapt. The cartel's history is closely intertwined with some of Mexico's most legendary drug lords and an ongoing struggle for control over lucrative smuggling routes to the United States.

The organization's roots trace back to the Guadalajara Cartel of the 1980s, which dominated Mexican drug trafficking at the time. When the Guadalajara Cartel was weakened by law enforcement efforts and internal conflicts, former members such as the charismatic Joaquín "El Chapo" Guzmán and the more reclusive strategist Ismael "El Mayo" Zambrada stepped forward. They formed alliances that laid the foundation for the new Sinaloa Cartel, bringing their experience, networks, and knowledge, which enabled rapid expansion in the 1990s.

2000s consolidation: Bloody victory and USA tunnels

In the early 2000s, the Sinaloa Cartel consolidated its position as a dominant player through bloody conflicts with rival cartels such as the Juárez Cartel and the Gulf Cartel. They secured control over vital smuggling routes to the USA, not least by exploiting widespread corruption and implementing advanced smuggling methods. The cartel's engineers developed complex underground tunnels beneath the Mexico-US border, often equipped with lighting, ventilation, and even rails capable of transporting tons of narcotics unimpeded. This technical innovation underscored the cartel's resourcefulness and foresight.

El Chapo and El Mayo: Empire leaders and their fall

For decades, Joaquín "El Chapo" Guzmán and Ismael "El Mayo" Zambrada formed the core of the Sinaloa Cartel's leadership. While El Chapo was the public face, notorious for his escapes and mythical status, El Mayo was the tactical mastermind, focusing on logistics, network building, and the systematic bribery of officials, all while avoiding the limelight. Under their leadership in the 2010s, the Sinaloa Cartel was responsible for up to half of all narcotics reaching the USA. El Chapo's spectacular prison escapes in 2001 and 2015 reinforced his legend, but his final capture in 2016 and subsequent life sentence in the USA in 2019 marked a significant turning point for the cartel.

After El Chapo: Fragmentation and Los Chapitos' fentanyl rule

Following El Chapo's downfall, the Sinaloa Cartel has become more fragmented, primarily divided into four main factions: Ismael "El Mayo" Zambrada's group, "Los Chapitos" led by El Chapo's sons, Aureliano "El Guano" Guzmán's faction, and Rafael Caro Quintero's network. Although these factions operate with considerable autonomy, they continue to share resources such as smuggling tunnels and money laundering networks. Los Chapitos have particularly distinguished themselves by dominating the production of the synthetic opioid fentanyl, while El Mayo traditionally focused on the cocaine trade until his presumed arrest in 2024.

Technological edge: Submarines, drones, and laundering

The Sinaloa Cartel has consistently pushed the boundaries of technological innovation in smuggling. In addition to traditional methods like narco-submarines and aircraft, they have implemented drones for cross-border drug transportation. Authorities have reported modified commercial drones capable of carrying up to 10 kg of methamphetamine across the Mexico-US border. They have also embraced cryptocurrencies like Ethereum to launder millions of dollars, often in collaboration with intermediaries from China, to obscure financial flows and evade international financial surveillance.

Fentanyl kings: Deadly production since 2020

Since 2020, the Sinaloa Cartel has increasingly dominated the fentanyl market. They import precursor chemicals from China and produce the deadly pills in clandestine laboratories in the state of Sinaloa, Mexico. According to US authorities, this cartel is behind an overwhelming share of the fentanyl seized in the USA – a drug that is a primary cause of the tragic surge in overdose-related deaths, with over 100,000 fatalities annually. This line of business is extremely profitable, generating vast sums of money for the organization; a pill that costs about $1 to produce can sell for up to $50 on the streets in the USA.

Global network: Alliances in Europe, Africa, Asia

The Sinaloa Cartel has also expanded globally, establishing partnerships in Europe, Africa, and Asia, underscoring the organization's nature as an international criminal enterprise. In Europe, they collaborate with Italian mafia families and Albanian criminal networks to secure cocaine distribution. In Africa, they have utilized local militias in the Sahel region to transport cocaine from Latin America to Europe via West African coasts. In Asia, they have established an important base in Hong Kong, from which they procure chemicals for methamphetamine production and coordinate distribution through alliances with Chinese triads and other criminal groups. These global networks demonstrate the cartel's ability to adapt to local conditions and exploit geopolitical weaknesses.

US pressure: FTO label and Ovidio Guzmán extradition

The Sinaloa Cartel has faced significant legal challenges, particularly from the USA. In February 2025, the cartel was designated a Foreign Terrorist Organization (FTO) by the United States, which has intensified international efforts to freeze its assets and combat its operations. This step followed a series of high-profile arrests, including that of Ismael "El Mayo" Zambrada in 2024 and the extradition of Ovidio Guzmán, one of El Chapo's sons, in 2023. Despite these measures, the cartel has maintained its operations through decentralization and the use of cryptocurrencies to circumvent financial restrictions and continue money laundering.

Corruption's power: Bribery securing Mexico survival

A crucial factor in the Sinaloa Cartel's long-term survival is its deep infiltration of political and judicial systems, especially in Mexico, through widespread corruption. Testimony from Joaquín "El Chapo" Guzmán's trial indicated that the cartel spent up to $1 million monthly on bribing high-ranking officials. This systematic corruption undermines both Mexican and international law enforcement efforts, making it extremely difficult to dismantle the cartel's power base and influence.

Indelible innovation: Tech and global dominance

Over decades, the Sinaloa Cartel has demonstrated an unparalleled ability to adapt, innovate, and withstand pressure from authorities worldwide. Despite leadership changes, international sanctions, and intensified law enforcement efforts, this cartel remains a central and formidable player in the global drug trade. The cartel's enduring capacity to leverage new technologies like drones and cryptocurrency, along with global alliances, combined with the unwavering demand for narcotics, will likely secure its position as one of the world's most powerful criminal organizations for the foreseeable future.
