Patrick Mahomes, Chiefs agree to max $503M deal, richest contract in pro sports history

The Kansas City Chiefs made sure they’ll have Super Bowl MVP Patrick Mahomes around as long as possible.

Mahomes agreed to a 10-year extension worth up to $503 million, according to his agency, Steinberg Sports. The deal is worth $477 million in guarantee mechanisms and includes a no-trade clause and opt-out clauses if guarantee mechanisms aren’t met.

It’s the richest contract in professional sports history, surpassing Mike Trout’s $426.5 million deal with the Los Angeles Angels.

“Since he joined the Chiefs just a few years ago, Patrick has developed into one of the most prolific athletes in all of sports,” Chiefs chairman Clark Hunt said in a statement about the quarterback who led them to their first championship in 50 years.
