 Kennedy was the subject of an article in The New York Times about racist practices at the banking firm JPMorgan Chase. In 2018, Kennedy attempted to deposit money earned from his football career at a local JPMorgan bank after talks with an employee who made a good impression on him, Ricardo Peters. Kennedy's ample wealth would have qualified him under normal circumstances as a "private client" who would qualify for a variety of perks. However, Peters, who is black, was fired from the bank for unclear and disputed reasons, and Kennedy's application buried. Kennedy recorded later conversations with the replacement employee at JPMorgan; in them, the new employee indicated that the regional manager was afraid of talking with a large black man like Kennedy, and that the coveted private client status was unlikely to come to Kennedy despite his large deposit. In addition, Ricardo Peters said that JPMorgan sometimes turned away black people with large savings; in one incident, Peters was directly discouraged by his boss from taking on as a client a black woman who had suddenly come into a large inheritance.
