Wahlberg was traded to the Anaheim Ducks as part of the trade package for Owen Zellweger. The 20-year-old registered 37 points in 68 AHL games for the Rochester Americans in 2025-26.

Wahlberg spent his first full North American season in the AHL, scoring 11 goals and 30 points in 63 games. He uses his large frame and speed to play a hard-nosed, physical, forechecking style. Despite a quick start, he experienced numerous stretches with zero points and was shut out during his six 2025 Calder Cup playoff games with Rochester. He represented Team Sweden at the World Juniors, scoring four goals and eight points in seven games. – Wahlberg spent his first full North American season in the AHL, scoring 11 goals and 30 points in 63 games.

He played 43 games in the SHL this past season with Malmo, scoring five goals and ten points.

Anton Wahlberg is a late riser in the 2023 draft class. His SHL performances in the back half of the season have been very impressive and I’d wager they will get him drafted in the first round despite being on very few draft lists as recently as January. Wahlberg tilts the ice in his team’s favour in just about every facet of the game apart from playmaking. He’s a sound defensive player who has flashed impressive tenacity and intensity on the fore and backcheck at times this season. He’s a strong skater, especially for his size, and is a very good puck carrier through the neutral zone. In the offensive zone, he remains in constant motion, trying to create and exploit soft ice. He’s a good net-front player and his shot is a scoring threat from medium range. As a whole, Wahlberg has a very enticing set of tools which give him second-line upside, and his foundation of habits and intelligence provide him a good fallback game, so even if his skill doesn’t lift him into a top-six, he would still project as a valuable player to have in a bottom six.
