Though it’s still months away, everyone’s already buzzing about the return of the NBA to NBC and Peacock in October. But thanks to a new streaming deal between the Big 12 Conference and NBC Sports, the pros won’t be the only ones gearing up for a major streaming boost when it’s finally tipoff time for the 2205-2026 hoops season.

Beginning this fall, Peacock will play host to a new season-long slate of Big 12 basketball games, featuring both in-conference and out-of-conference matchups that can’t be seen anywhere else. The just-announced addition of Big 12 action adds to a stacked Peacock college basketball lineup that features nearly 200 men’s and women’s games from the Big Ten, the BIG EAST, and more — many of which will be only be presented live on Peacock.
