Overview
After years of discussion, the NBA appears to be moving toward adding two franchises, with reporting indicating the board of governors will vote to explore teams in Seattle and Las Vegas for the 2028–29 season. This briefing summarizes how expansion could unfold, what’s driving it, and the big outstanding decisions.
Why now?
- Expansion is primarily an economic decision for existing owners. Selling new franchises dilutes ownership shares but generates large expansion fees that go directly to owners. Published ranges put fees in the roughly $7–$10 billion-per-team range; combined proceeds could be on the order of tens of billions, making the timing attractive.
- Beyond revenue, both Seattle and Las Vegas are viewed as ready markets with viable arenas and fan interest, which reduces some of the traditional franchise risk.
Likelihood and process
- An exploratory, nonbinding vote is expected first; insiders say a formal approval could follow as soon as the July board meeting during Las Vegas Summer League. Final approval of expansion requires 23 of 30 owner votes.
Players and the NBPA
- The board of governors controls expansion; the players’ union does not have a veto.
