NBA Rookie of the Year Odds 2025: Wells Closing Gap on Favorite Castle
Stop me if you've heard this before: the NBA Rookie of the Year odds landscape is shifting again.
San Antonio Spurs guard Stephon Castle still has a narrow lead atop the oddsboard, but he and Memphis Grizzlies wing Jaylen Wells have separated themselves from the pack. Wells' odds have shortened significantly as he makes a push for the award throughout the season's home stretch.

🏰 Stephon Castle Rookie of the Year odds (-115)
We've been calling attention to Castle's value since he was trading at +2000 odds early in the year. The Spurs remained in the thick of the NBA Play-In Tournament odds race in the West before the trade deadline, which is why they moved for De'Aaron Fox and sent Castle to the bench.
San Antonio being all but out of contention because of the Victor Wembanyama injury hasn't led to the uptick in minutes for the rookie that some expected. Castle, though, has impressed with a high-scoring output during his fluctuating minutes. If he gets more involved, Castle's handle on the award could reflect on the oddsboards.

🐻 Jaylen Wells Rookie of the Year odds (+275)
Memphis' second-round pick leads all rookies in win shares, and he's second in total points, trailing only the aforementioned Castle. Wells has seen an uptick in scoring since returning from the All-Star break as he looks to improve upon his 11.4 points per game throughout the year.
Overall, the Grizzlies wing has proven he's in the Rookie of the Year race to stay. If he can continue to score at a consistent clip, his odds will continue to shrink. We believe he's worth a flier at +275 odds for that reason, and a $10 winning wager would pay out $27.50 in profits.

💡 How to bet on NBA Rookie of the Year
Betting on the NBA Rookie of the Year (ROY) is pretty straightforward. First, pick a reputable sportsbook that offers ROY futures. Check out the odds for different rookies; for instance, if Player A has +300 odds and Player B has +500, Player A is more likely to win. Place your bet by deciding how much you want to wager. If you bet $100 on Player A at +300 and they win, you’ll get $400 back ($100 stake + $300 profit). Keep an eye on the rookies’ performances throughout the season to see how your bet is shaping up.
Now, why do odds move in future markets? Well, it’s mostly about performance and perception. If a rookie starts playing really well or gets injured, their odds will change. A lot of people betting on the same player can also cause the odds to shift as sportsbooks try to manage their risk. Plus, expert predictions and analysis can influence how people bet, which in turn affects the odds. Understanding these factors can help you make smarter bets and maybe even catch some favorable odds shifts.
📖 How to read NBA Rookie of the Year odds
Reading NBA Rookie of the Year (ROY) odds is simple once you know the basics. Odds are typically presented in a format like +300 or -150. Positive odds (e.g., +300) indicate how much profit you'd make on a $100 bet. For instance, a $100 bet at +300 odds would win you $300, plus your initial $100 stake, totaling $400. Negative odds (e.g., -150) show how much you need to bet to win $100. So, a $150 bet at -150 odds would win you $100, plus your $150 stake, totaling $250.
Odds also reflect the probability of an outcome. Lower odds (e.g., +100) suggest a higher probability of the player winning, while higher odds (e.g., +1000) indicate a lower probability. Sportsbooks adjust these odds based on factors like player performance, injuries, and betting patterns.
For example, if Rookie A has +200 odds and Rookie B has +500 odds, Rookie A is considered more likely to win. If you bet $100 on Rookie A and they win, you'd get $300 back ($200 profit + $100 stake). Reading and understanding these odds helps you make informed betting decisions.
