Sonny Vaccaro predicted that Zion Williamson will receive a record endorsement deal for a rookie from a sneaker company.

"In my lifetime, I think it's going to be the biggest bidding war ever done," said Vaccaro.

LeBron James signed a 7-year deal worth $87 million with Nike before ultimately getting a lifetime deal. Kevin Durant signed a 7-year, $60 million deal with Nike before his rookie season.

Sneaker insiders predict that Williamson will ink a deal before the May 14th draft lottery. There could be up to 6 sneaker brands - Nike, Adidas, Under Armour, New Balance, Puma, and Anta - in contention for his signature. 

Williamson's AAU team was sponsored by Adidas.

Vaccaro added that Williamson's appeal goes beyond sneakers.

"If Zion doesn't change, I predict that he will be the first basketball athlete at 18 years old that the world is rooting for to become a billionaire. I say billionaire, very easily. He is going to have an opportunity to be the face of every company and every major corporation. He is the most marketable person I've seen, for a lot of different reasons."
