Ismael “El Mayo” Zambada, the legendary co-founder of Mexico’s notorious Sinaloa Cartel, has been sentenced to life in prison after agreeing to forfeit $15 billion in illicit proceeds, one of the largest forfeiture orders in U.S. criminal history.
Zambada, 76, co-founded the Sinaloa Cartel alongside Joaquín “El Chapo” Guzmán in the late 1980s and spent more than three decades overseeing one of the world’s most powerful drug trafficking organisations.
Under a plea agreement with U.S. prosecutors, he pleaded guilty last year to operating a continuing criminal enterprise and racketeering conspiracy. As part of the agreement, he will forfeit up to $15 billion, representing the cartel’s illicit proceeds accumulated over more than 30 years.
Long regarded as the cartel’s chief strategist, Zambada maintained a low public profile while allegedly directing a vast criminal network responsible for trafficking cocaine, heroin, fentanyl and other narcotics into the United States. Prosecutors said he relied on deep-rooted corruption, bribing politicians and senior military officials to protect the cartel’s operations.
Federal prosecutors described him as “one of the most—if not the most—prolific and powerful narcotraffickers in the world,” alleging that under his leadership the Sinaloa Cartel distributed at least 1.5 million kilograms of cocaine while expanding into heroin and fentanyl trafficking.
Court filings also accused the cartel of carrying out kidnappings and assassinations while using sophisticated smuggling routes, including cross-border tunnels and railway networks, to move drugs into the United States.
Zambada’s capture in 2024, after he was allegedly abducted and flown to the United States by Joaquín Guzmán López, a son of “El Chapo,” triggered a violent power struggle within the Sinaloa Cartel. The conflict has reportedly claimed thousands of lives across Mexico’s Sinaloa state.
Although prosecutors secured a record $15 billion forfeiture order, legal experts believe recovering the full amount is unlikely because much of the cartel’s wealth remains hidden or beyond the reach of authorities.
According to the United Nations Office on Drugs and Crime (UNODC), Mexican drug trafficking organisations generate more than $12 billion annually from the sale of heroin, methamphetamine and cocaine.
Having evaded capture for decades, Zambada had been indicted 16 times in the United States since 2009. His lawyers acknowledged that his guilty plea carries a mandatory life sentence and requested that he be housed in a federal medical facility because of age-related health conditions rather than the Supermax prison where “El Chapo” is serving his sentence.
Meanwhile, authorities say violence linked to the cartel’s internal conflict has left more than 3,500 people dead and over 4,100 people missing in Sinaloa since Zambada’s arrest, underscoring the lasting impact of one of the world’s most powerful criminal organisations.
