The deal has escalators that would make it worth even more if Fox makes an All-NBA team and the NBA's salary cap rises above $112 million, Gaston said.
Fox would earn a total of $170 million in the deal for being an All-NBA third-team selection, $183 million for a second-team selection and $196 million for a first-team selection, according to Gaston.
Fox, who will turn 23 next month, averaged a career-best 21.1 points to go with 6.8 assists and 3.8 rebounds per game last season.
A Kentucky product, he has steadily improved since he was taken with the fifth pick in the 2017 NBA draft. The Kings are banking on Fox's being able to deliver the franchise to its first playoff berth since 2006.
