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.

“With his dynamic play and infectious personality, he is one of the most recognized and beloved figures to put on the Chiefs uniform. He’s an extraordinary leader and a credit to the Kansas City community, and I’m delighted that he will be a member of the Chiefs for many years to come.”
