While the league has not committed to that path yet, it has explored the idea with a reportedly exorbitant price tag. According to ESPN's Brian Windhorst, the NBA has floated an expansion fee of $2.5 billion apiece for two new teams, with multiple offers expected from Las Vegas and Seattle-based groups.

ANALYSIS: The NBA is in dire need of a cash infusion, and with no plans to allow fans back into arenas, Adam Silver could look to add two expansion teams to provide financial relief to its existing 30 teams.
It should be noted that these are just exploratory rumors right now, but the rumored price tag on a possible expansion team entry fee will be roughly $2.5 billion dollars, which would represent the highest sale price for a professional sports team in North American history.
