One reason the NBA isn’t yet prepared to dive head-long into expansion talks is that a potential Celtics sale could reset the market, sources tell ESPN’s Tim Bontemps, Kevin Pelton, and Brian Windhorst. If the Celtics set a new record for the highest sale price ever for an NBA team, it would only increase the price tag for incoming expansion franchises, as ESPN’s trio notes.

Commissioner Adam Silver recently stated that the NBA is “not quite ready” to move forward on the expansion process, though he left the door open for those discussions to happen later on in the 2024/25 league year.

With the NBA continuing to drag its heels on expansion, league sources and people connected to potential bidding groups are viewing the 2027/28 season as the target date for when one or more expansion teams could begin playing, with the ’26/27 campaign considered an increasingly unrealistic – albeit not impossible – option, according to Bontemps, Pelton, and Windhorst.

Based on the growing valuations of NBA franchises, it’s not unrealistic to project that a pair of new teams could net the league $10 billion combined – or even more than that – in expansion fees, ESPN’s reporters suggest.

While some current NBA team owners are wary of further diluting their share of the league’s revenue by slicing off two more pieces of a “pie” currently being shared 30 ways, expansion fee payments (which don’t have to be shared with the players’ union) exceeding $300MM apiece could help sway those ownership groups, as Bontemps, Pelton, and Windhorst point out. Additionally, the $76 billion media rights deal negotiated by the NBA earlier this year has assuaged some owners’ concerns about sharing revenues with 31 partners instead of 29, the ESPN trio adds.

Here are a few more items of note from ESPN’s in-depth FAQ on the possibility of expansion:

• Although the National Basketball Players Association has no real voice in the expansion process, the union would be “very much in favor” of adding 36 new jobs (30 standard roster spots and six two-way slots) for its members, sources tell ESPN.
• Seattle and Las Vegas are widely considered the favorites to land expansion teams, but they likely won’t be the only cities receiving consideration. Sources who spoke to ESPN view Mexico City as the most likely candidate to seriously enter the mix along with Seattle and Vegas, though Bontemps, Pelton, and Windhorst acknowledge there would be a number of “logistical hurdles” to contend with.
• If Seattle and Las Vegas land expansion teams, they would both have to be Western Conference clubs, meaning one current Western team would have to move to the Eastern Conference. According to ESPN, that decision would likely come down to the Pelicans, Grizzlies, and Timberwolves, with Minnesota considered the most logical choice to move East since the Wolves are geographically closer to five Eastern opponents than they are to their closest Western opponent (Denver). Still, it could be a “protracted fight” to determine which team would change conferences.
• The ownership group of the NHL’s Seattle Kraken – led by Samantha Holloway and her father David Bonderman – is considered the most likely bidder for a Seattle franchise, per ESPN. Hall of Fame NBA executive Rick Welts has served as an advisor for the Kraken ownership group, which also includes the sons of former Sonics owner Barry Ackerley. Chris Hansen, who previously attempted to relocate the Sacramento Kings to Seattle, isn’t expected to lead a bid to bring the NBA to the city, but would be willing to assist in the process, ESPN’s trio adds.
• Active NBA players aren’t permitted to own a stake in an existing franchise, but the rules for an active player becoming a stakeholder in an expansion franchise (before it begins play) aren’t as clear. Those rules may need to be clarified in the coming years, with LeBron James seriously interested in getting involved in a bid for a Las Vegas team. According to ESPN’s report, former Bucks co-owner Marc Lasry is putting together a group to bid for a Vegas franchise — that group is expected to include longtime WNBA star Candace Parker.
