Who Will Win NBA Rookie of the Year in 2026?

Flagg begins as the betting favorite at -225 to win the NBA Rookie of the Year award during the 2025-26 season.

Although itโ€™s not surprising to see Flagg start as the ROY front-runner, his price tag to win this award is notable. If his price holds until October, Flagg would be the biggest preseason favorite to win Rookie of the Year since at least 2007, as the Sports Odds History database doesn’t go back further than that.

Kevin Durant and Wembanyama are the only other rookies to have minus odds prior to the start of the season. Durant was -200 before claiming the trophy in 2007-08, while Wembanyama was -145 (as of Oct. 24) en route to securing the award in 2023-24.

However, it’s worth noting that Wembanyama didn’t maintain his status as the favorite from start to finish. He was eventually passed by Oklahoma City Thunder big man Chet Holmgren, which allowed bettors to take advantage of some plus-money prices on Wembanyama.

Flagg is a deserving favorite, especially as a generational prospect in a rookie class that lacks a lot of top-end talent. But I have a hard time backing him at his current odds.

As a result, I’d rather target a player further down the board and hope for better value on Flagg at a later date.

Because high-draft picks have an advantage, it’s worth targeting the four players who heard their names called right after Flagg went No. 1 overall.

Dylan Harper (No. 2 pick) could become the third straight Spurs player to win this award, though he’s likely to come off the bench unless there is a trade that opens his path.

V.J. Edgecombe (No. 3 pick) won’t have the counting stats unless the Philadelphia 76ers have another injury-riddled season. Kon Knueppel (No. 4 pick) could have a similar usage problem with the Charlotte Hornets.

The player that should step into a high-usage role on a bad team from Day 1 is Ace Bailey, who was drafted No. 5 overall by the Utah Jazz. His pre-draft process garnered a lot of attention, but he’s also a walking bucket and the exact type of player who can challenge Flagg in this race.

Flagg is still my pick to win ROY, but it’s Bailey or pass from a betting perspective.

Prediction: Cooper Flagg
