As of March 23, 2026, Yes shares for New York Islanders defenseman Matthew Schaefer to win the Calder trade at 97 cents, implying an overwhelming 97% crowd-sourced probability of claiming the award.

Current Top Contenders in the Calder Memorial Trophy Market
- Matthew Schaefer (New York Islanders) – 97% (Yes at 97¢)
- Macklin Celebrini (San Jose Sharks) – 1.5–2%
- Cutter Gauthier (Anaheim Ducks) – 1–1.5%
- Other rookies (including emerging defensemen and forwards) – <1% combined
Schaefer’s probability has remained exceptionally high since early February 2026, when it first climbed above 90%. The 18-year-old defenseman has separated himself from the field through consistent excellence and impact on a rebuilding Islanders team.
Why Schaefer Is the Overwhelming Favorite
Several factors explain the near-unanimous trader support for Matthew Schaefer as the 2025-26 Calder Memorial Trophy winner:
- Elite Production for a Defenseman — Schaefer has recorded 48 points (12 goals, 36 assists) in 68 games, an exceptional output for a rookie blueliner. His ability to contribute offensively while maintaining strong defensive metrics has drawn widespread praise.
- Ice Time and Responsibility — The Islanders have trusted Schaefer with top-pair minutes, including power-play and penalty-kill duties. He leads all rookies in average time on ice and ranks highly in advanced metrics such as expected goals for percentage and Corsi.
- Team Context — Despite the Islanders’ modest standing in the Metropolitan Division, Schaefer’s individual impact has been undeniable. He has frequently been the catalyst for transition play and zone exits, providing stability on a young defensive corps.
- Lack of Serious Challengers — While Macklin Celebrini and Cutter Gauthier have enjoyed strong rookie campaigns, neither has matched Schaefer’s combination of production, consistency, and two-way reliability. The gap in voter perception, mirrored by Polymarket traders, has widened significantly.
The market’s extreme skew toward Schaefer reflects a consensus that only a major late-season collapse or injury would prevent him from claiming the award.
Market Mechanics and Resolution
Polymarket’s 2025-26 NHL Calder Memorial Trophy contract is binary. It resolves Yes if Matthew Schaefer is officially named the winner by the Professional Hockey Writers’ Association. In the event of a tie (rare for the Calder), the market typically resolves No unless specific rules state otherwise.
High volume and tight spreads ensure the price accurately incorporates the latest information, including injury updates, statistical milestones, team performance, and expert commentary. The probability has held steady near 97% for several weeks, with minimal movement even after strong performances by other rookies.
What Traders Are Watching in the Final Weeks
The remaining regular-season games will have limited impact on the outcome, given Schaefer’s substantial lead in key voting metrics:
- Sustained Performance — Continued strong play from Schaefer would further solidify his position.
- Injury Risks — Any significant absence for Schaefer or a sudden surge from a rival could cause minor shifts, though a reversal appears highly unlikely.
- Voter Sentiment — Final voting occurs after the regular season. Schaefer’s two-way game and leadership qualities have resonated strongly with writers.
For NHL fans tracking the 2025-26 Calder Memorial Trophy race, Polymarket provides one of the clearest public signals of collective belief. Schaefer’s 97% probability reflects near-universal agreement that the young defenseman is the most deserving rookie of the season.
As the regular season winds down, this market stands as a near-certainty in an otherwise unpredictable NHL campaign. Matthew Schaefer’s remarkable rookie year is on track to be rewarded with the league’s top individual honor for first-year players.
