How would an NBA expansion to 32 teams work?

NBA Commissioner Adam Silver addressed league expansion during comments on Tuesday night, clarifying that it is currently a "curiosity" rather than a concrete plan. He stated the league needs to "do the work" to evaluate whether expansion beyond 30 teams is beneficial ("additive"), considering economic impact, competitive balance, and national footprint. Silver emphasized assessing potential markets' desire for a team and their infrastructure capabilities.

The analysis identifies three primary cities frequently discussed as potential NBA expansion locations, envisioning a move to 32 teams. Seattle is presented as the most obvious choice, with fans longing for the return of the Supersonics since their 2008 relocation. Arguments for Seattle include its position as the 20th largest US media market (larger than nine current NBA teams), proven ability to support professional sports (highlighting the NHL's sellout Kraken), and the emotional appeal of restoring a historic franchise.

Las Vegas is described as inevitable ("when not if"), likely within the next five years, driven by strong financial potential. Silver himself has referred to it as the potential "31st franchise." The city's embrace of the WNBA's Las Vegas Aces (top attendance) demonstrates existing local fan support beyond just tourism. Placing an expansion team in Vegas, rather than relocating an existing team, is seen as preferable, capitalizing on its status as a major tourist destination to boost visiting team attendance.

Mexico City represents a significant international opportunity for the NBA, tapping into Mexico's surging basketball interest, including a reported 25% year-over-year viewership jump (2022-2023), making it a top 10 international market. It would become the NBA's largest city by population. While the massive population suggests strong support potential, the main hurdle identified is establishing the necessary infrastructure. Despite the logical appeal, Mexico City is viewed as less realistic for near-term expansion compared to Seattle or Vegas, noting the NFL's prolonged but unrealized efforts there.
