The NBA is currently under investigation by the Department of Justice (DOJ) due to suspicions that the league interfered with Ice Cube's BIG3 basketball league. This information was reported by TMZ Sports. The DOJ is probing allegations that the NBA tried to undermine the success and growth of the BIG3 league. They are suspected of using their influence and power to deter potential sponsors, television networks, NBA players, and referees from associating with the BIG3.

There are claims that the NBA has set rules that prevent current players from participating in the BIG3. This is notable because many NBA players engage in various summer and international leagues during their offseason. Additionally, the NBA is believed to have used similar strategies to discourage referees from officiating BIG3 games, even though these referees are permitted to work in other leagues.
