BJ's Wholesale Club is not owned by BlackRock, as it operates as a widely held, publicly traded corporation listed on the New York Stock Exchange under the ticker symbol BJ. While massive global asset management firms like BlackRock, The Vanguard Group, and other institutional investment entities own substantial blocks of shares on behalf of their mutual fund and exchange-traded fund clients, these holdings represent passive institutional investments rather than outright corporate ownership or private control of the warehouse enterprise.
