Wembymania is transforming one of the sleepier parts of the NBA’s calendar.

The fan frenzy over rookie Victor Wembanyama, the San Antonio Spurs’ No. 1 overall draft pick, has created unprecedented levels of ticket sales for the NBA Summer League, a developmental event growing quickly in stature but historically followed by only the most avid of basketball fans.

Tickets for Wembanyama’s Summer League debut Friday in Las Vegas are no longer available on the primary market, with all 17,500 seats at UNLV’s Thomas & Mack Center selling out by Wednesday.
