Expansion of the NBA

Since beginning with 11 teams in 1946, the National Basketball Association expanded several times before reaching its current 30 teams. The most recent additions were the Charlotte Hornets and Miami Heat (1988), the Minnesota Timberwolves and Orlando Magic (1989), the Toronto Raptors and Vancouver Grizzlies (1995; the latter relocated to Memphis in 2001), and the Charlotte Bobcats (2004).

Commissioner Adam Silver stated in a February 2024 interview on The Pat McAfee Show that Las Vegas was an expansion team candidate. Seattle is also considered a top expansion candidate should an expansion occur, with Mexico City, Montreal, and Vancouver also being less likely expansion options. In September 2024, Silver stated that the NBA would have discussions about a potential expansion of the league sometime during the 2024–25 season, with an ESPN article stating that the potential expansion teams may begin play in the 2027–28 season should one occur. In April 2025, Silver stated that the league could begin a formal expansion process in the summer of 2025.
