As sports contracts continue to break records, the race for the title of the largest deal in history has produced a lineup of astonishing figures. From baseball to soccer, athletes across the globe are landing contracts worth hundreds of millions, showcasing the ever-growing financial power of professional sports. This article explores the most lucrative contracts ever signed, highlighting the athletes and the staggering amounts involved.
The Changing Landscape of Sports Contracts
In March 2019, Mike Trout made headlines when he signed a 12-year, $430 million contract with the Los Angeles Angels, a deal believed to be the largest guaranteed contract awarded to an athlete at that time. Trout’s average salary amounted to approximately $36 million per year.
However, it soon became apparent that Lionel Messi was quietly raking in a far more substantial sum under his contract with FC Barcelona. In January 2021, Spanish newspaper El Mundo leaked details of Messi’s four-year contract, revealing an astronomical value of $674 million. This revelation shifted the narrative globally, showing that Messi, with an average annual salary of $168.5 million, actually held the title for the most lucrative sports contract up to that point.
The record for the largest sports contract has since continued to evolve. December 9, 2023, marked a new milestone when Shohei Ohtani signed a 10-year, $700 million deal with the Los Angeles Dodgers, surpassing all previous contracts in headline value. Barely two years later, this record was eclipsed by Juan Soto’s remarkable 15-year, $765 million contract with the New York Mets.
