It’s been 20 years since the last NBA expansion, as the then-Charlotte Bobcats, now-Charlotte Hornets joined the league during the 2004–05 season. That gave the NBA uniformity with 30 teams and allowed for six divisions of five teams each.
The topic of NBA expansion has been widely discussed in the two decades since, but there’s been no real movement. That appears to be changing entering the 2024–25 NBA season, with commissioner Adam Silver stating that NBA expansion will be discussed at some point “this season.”
