Justin Gaethje says a disappointing payday in his last bout pushed him toward a title-or-retire mindset.
Gaethje faces Paddy Pimblett for the interim lightweight title at UFC 324.
The opportunity arose after Ilia Topuria stepped away temporarily.
Gaethje had warned he would consider retirement without a title fight.
He revealed his bout with Rafael Fiziev was the first time he earned less than a previous fight.
That result strengthened his resolve to compete only in the biggest matchups.
Gaethje said championship pay now aligns with his contract and career goals.
At 37, he admits he is nearing the end of his career.
His plan is clear: beat Pimblett, challenge Topuria, then decide his future.
