At the 2016 Junior World Championships in Sochi, Odermatt won the bronze medal in super-G and the gold medal in giant slalom, which allowed him to make his World Cup debut in March 2016 in the giant slalom at the season finals in St. Moritz. At the 2018 Junior World Championships in Davos, Odermatt won an unprecedented five gold medals (combined, downhill, super-G, giant slalom, and team event).
He gained his first World Cup podium at Kranjska Gora in March 2019,[1] and his first win in December 2019 in a super-G at Beaver Creek.[2] In the next season, Odermatt achieved his first victory in giant slalom in Santa Caterina[3] and finished second in the giant slalom and overall World Cup titles, both times after Alexis Pinturault.
Odermatt had his breakthrough in the 2021–22 season, winning seven races as well as the overall and giant slalom season titles. He achieved his childhood dream of winning the historic giant slalom in Adelboden and represented Switzerland at the 2022 Winter Olympics, where he won the gold medal in the giant slalom, recording the fastest time in the first run and finishing 0.19 seconds ahead of runner-up Žan Kranjec.[4] The next season, Odermatt set a new record for overall men's points in a World Cup season with 2,042,[5] overtaking Hermann Maier, and tied Maier (2000–01), Ingemar Stenmark (1978–79) and Marcel Hirscher (2017–18) for the men's record for most wins in a World Cup season with 13. He also won gold medals in downhill and giant slalom at the 2023 World Ski Championships, recording his first win in a professional downhill event.
In the 2023–24 season, Odermatt again claimed 13 wins, including the first 9 giant slalom races, and became the fourth man in World Cup history to win four season titles in the same year, claiming the overall, downhill, super-G and giant slalom globes.[6] The following year, Odermatt surpassed Pirmin Zurbriggen as the most successful male Swiss skier in World Cup history with his 41st victory,[7] and became the second man to win four consecutive GS races in Adelboden after Stenmark (1979–1982).[8]
