Hintermann made his World Cup debut at age 20 in November
2015 at
Lake Louise, and was 40th in the downhill. He scored his first World Cup points three weeks later at
Val Gardena, at 29th place in the downhill. Hintermann won his first World Cup race (and first podium) the following season, in the
combined at
Wengen in January
2017. In October 2024, Hintermann announced that he had been diagnosed with lymphoma, which is why he did not compete in any races during the 2024–25 World Cup season. On 13 March 2026, Hintermann declared his immediate retirement, citing what he regarded as the excessive risks of the sport. He stated that before his last downhill races, he had suffered from panic attacks. Since he had qualified by finishing among the top 25 in the
2026 downhill standings, race organizers at the World Cup Finals gave Hintermann a farewell run at
Kvitfjell – the site of Hintermann's two downhill World Cup victories. ==World Cup results==
