NBA Rookie of the Year Prediction Markets: Cameron Boozer’s Early Lead Over the 2026 Draft Class

The 2026 NBA Draft class is only a few weeks old, but prediction markets are already picking favorites for Rookie of the Year, and the early Summer League slate is giving bettors plenty to chew on. Markets tracking the award have pulled in well over a million dollars in volume on some outcomes, a sign of just how much attention this rookie class is getting before a single regular-season game tips off.

From Duke’s Cameron Boozer landing in Memphis to a trio of first-round picks turning heads in Las Vegas and Salt Lake City, the gap between what sportsbooks priced in on draft night and what’s actually happening on the floor is narrowing fast.

What the Prediction Markets Are Saying

Prediction markets built around the 2026-27 Rookie of the Year race are treating most individual long shots as extreme underdogs, with several outcomes pricing in around a half a percent or less. That’s standard for a field this deep, but the total money moving through these markets shows real appetite for betting on which rookie breaks out first.

• Cameron Boozer (Memphis Grizzlies, No. 3 overall) opened as the overall favorite for Rookie of the Year at sportsbooks like BetMGM, priced around +240
• AJ Dybantsa (Washington Wizards, No. 1 overall) and Darryn Peterson (Utah Jazz, No. 2 overall) both opened around +400
• Later first-round picks like Zuby Ejiofor (Atlanta Hawks, No. 23), Allen Graves (Toronto Raptors, No. 19) and Chris Cenac Jr. (Boston Celtics, No. 27) are longer shots in the prediction markets, but each has already flashed real production

Summer League Form Is Backing Up the Betting Markets

Boozer wasted no time validating his draft slot. In his Las Vegas Summer League debut, the Grizzlies forward dropped 23 points on 7-of-12 shooting to go with six rebounds and four assists in a win over Chicago. Through three summer outings spanning Las Vegas and Salt Lake City, he’s averaging 18.7 points, 5.7 rebounds and 4.0 assists while shooting north of 62 percent from the field. That kind of efficiency out of the gate is exactly why oddsmakers made him the favorite even though he went third overall rather than first.

The later picks aren’t fading quietly, either. Ejiofor, the 23rd overall selection out of St. John’s, has posted a double-double in every Summer League appearance for Atlanta, including a 19-point, 15-rebound line in a win over Oklahoma City. Graves, taken 19th by Toronto, torched the Celtics for 22 points and 13 rebounds on 9-of-16 shooting in his summer debut, an overtime loss that still turned heads around the league. And Cenac Jr., Boston’s No. 27 pick out of Houston, forced that same overtime with a buzzer-beating three before finishing with 14 points, 10 rebounds and four blocks.

Prediction Markets vs. Sportsbooks: Different Angles on the Same Question

It’s worth understanding how these two betting products differ before putting any money down. Traditional sportsbooks price Rookie of the Year as a futures market with odds tied to a payout, while prediction markets let bettors trade contracts on binary outcomes that move in real time as new information comes in. Anyone comparing a live NBA odds board to a prediction market screen will notice the contract prices update far more aggressively after events like a breakout Summer League performance.

That’s part of why the gap between Boozer’s price and the later first-rounders is so wide right now. The books and markets alike are still weighting draft slot and expected role heavily, but three strong summer showings from Ejiofor, Graves and Cenac Jr. are the exact kind of data points that can shift a long shot into a live underdog fast.

Who Has the Edge Right Now

Nothing about Rookie of the Year is settled in July, and Summer League is a small sample against lesser competition. Still, Boozer’s blend of draft pedigree, opportunity in a rebuilding Memphis backcourt-heavy roster and immediate on-court efficiency make him the most defensible favorite across both sportsbooks and prediction markets today. Bettors comparing futures at DraftKings against a prediction-market contract should watch how Boozer’s price moves once the preseason schedule starts, since that’s typically when public perception catches up to what these early performances are already showing.

For now, the Ejiofor, Graves and Cenac Jr. storylines are worth monitoring as value plays rather than favorites. If any of the three carries Summer League momentum into training camp with real rotation minutes, the prediction markets pricing them near zero could look very different by opening night. Anyone using a betting calculator to weigh these long shots should factor in how thin the current sample size really is before committing serious stakes.
