  • San Antonio Spurs guard Stephon Castle won ROY in 2025.

For the second straight season, a San Antonio Spurs player won Rookie of the Year.

Stephon Castle claimed NBA’s Rookie of the Year award in 2025 after averaging 14.7 points, 3.7 rebounds, and 4.1 assists in 26.7 minutes per game. Castle led all rookies in total points (1,190), steals (74), and free throws made (249).

This comes after Spurs center Victor Wembanyama established himself as a franchise player with his Rookie of the Year campaign in 2023-24. The future is bright in San Antonio.

NBA betting odds for the 2025-2026 Rookie of the Year market won’t be released until draft night, which is slated to take place on Wednesday, June 25.

Odds to Win NBA Rookie of the Year

While NBA odds likely won’t be made available until draft night, bettors will act fast when this market is released.

Washington Wizards center Alex Sarr started as the betting favorite, but was quickly passed by Memphis Grizzlies center Zach Edey, who entered the year with +300 odds to win ROY. Edey was one of the more popular bets last summer, starting as early as draft night when he was selected with the No. 9 pick.

Castle entered the year with a +1200 value after being the No. 4 overall pick. He earned more usage as the season went on, but his ROY campaign benefited from a weaker class.

That won’t be the case next year.

Cooper Flagg, who is expected to be the No. 1 overall pick, will likely start as the betting favorite. He should have a more favorable price than Wembanyama, who was a -145 preseason favorite in 2023-24. But I’d expect bettors to be interested in backing Flagg at any number right away.

Dylan Harper, VJ Edgecombe, Ace Bailey, and Tre Johnson will likely be Flagg’s biggest challengers in this market. Their landing spot could ultimately determine their chances of making an immediate impact.

Still, this is probably Flagg’s award to lose next year.

Prediction: Cooper Flagg
