The 2025 NBA draft lottery is next week and could change the fortunes of a struggling franchise.
Duke's Cooper Flagg is the overwhelming favorite to be the No. 1 overall selection, and the lottery will determine which team gets the right to select him.
What follows is a look at the rules for the NBA draft lottery, each team's odds for the 2025 edition of the event, and an overview of the lottery's history.
NBA Draft Lottery Rules
Every NBA team that doesn't make the postseason is eligible for the lottery. That leaves 14 teams with a chance of landing the top pick in the draft. Each team is assigned odds for landing the top selection in the reverse order of the standings. The teams with the three worst records in the league have the highest odds of receiving the top selection at 14.0%. The odds decrease after that, with the 14th worst record having only a 0.5% chance of getting the top selection.
The default odds are as follows.

NBA Draft Lottery History
The NBA draft lottery began in 1985 as a way to combat perceived tanking by the league's worst teams in order to obtain the top players entering the draft. The system was implemented to add an element of luck to the process.
The first lottery system involved the random drawing of an envelope from a hopper with each envelope having a team's name on it. Each team in the lottery therefore had the same odds of landing the top slection. The New York Knicks were the winners of the first lottery in 1985 and subsequently drafted Patrick Ewing with the first selection.
In 1987, the league modified the lottery system so that only the three picks were determined by it. After the top three selections were assigned, the remaining non-playoff teams would select in reverse order of their records.
The envelope system was in use until 1989 when the league switched to a weighted lottery system in 1990. The odds and processes have been modified slightly over the years with the latest change coming in 2019. Now, the league's three worst teams have equal odds of landing the top pick as a defense against tanking for the top selection.
