Jay-Z does not own a stake in the Brooklyn Nets. The iconic rapper and entrepreneur purchased a small minority ownership percentage in the franchise back in 2003 when the team was still located in New Jersey, and he played a massive promotional role in helping orchestrate their relocation to the Barclays Center in Brooklyn. However, in 2013, he sold his entire ownership share to launch his new career as a certified sports agent with Roc Nation Sports, complying with strict NBA rules that prohibit team owners from simultaneously representing professional athletes.
