What Is the Largest Contract in NFL History
The largest contract in NFL history is the fully guaranteed deal signed by quarterback Josh Allen with the Buffalo Bills in April 2024. The contract is worth up to $258 million over six years, with a record $150 million guaranteed at signing, making it the highest total value and largest guaranteed package in league history. The deal is structured with significant escalators tied to passing yards and touchdowns, which push the potential total value to the top of the list.
The previous record holder was quarterback Patrick Mahomes of the Kansas City Chiefs, whose 10-year extension signed in July 2020 was worth up to $450 million with $141 million guaranteed. Mahomes' deal remains the highest average annual value ever at $45 million per year, but Allen's new contract surpasses it in total money and guaranteed cash, reflecting the current market for elite quarterbacks. Both contracts are fully guaranteed for injury and include large signing bonuses that set new benchmarks for NFL compensation.
