Paris made his World Cup debut in December 2008 and won his first World Cup race in late December 2012 in Italy, a dead-heat tie with Hannes Reichelt in the downhill on the Pista Stelvio at Bormio. Aksel Lund Svindal was just one hundredth of a second behind for third and Klaus Kröll was fourth, just one hundredth behind Svindal. It was the closest top-four finish in World Cup downhill history (0.02 of a second) and the first tie in a men’s downhill in nearly 35 years (January 1978). Four weeks later, Paris firmly established himself as a top downhill racer on the circuit with a win at Kitzbühel on the classic Streif course.

At the 2013 World Championships in Austria, Paris won the silver medal in the downhill, 0.46 seconds behind gold medalist Aksel Lund Svindal.

Paris gained his first victory in Super-G at Kitzbühel in 2015, and placed second in the downhill the next day. Two years later in 2017, he won his second downhill on the Streif course and in 2019 he concluded a “Hahnenkamm hat trick” with his third downhill win at Kitzbühel. This third victory ties him with Pirmin Zurbriggen, Luc Alphand and Franz Heinzer as the third most successful downhill racer at Kitzbühel; only Franz Klammer, Karl Schranz, (4x) and Didier Cuche (5x) won more often – but only few of them on the entire length of the original ‘Streif’ run.

Paris started the 2019–2020 season with runner-up finishes in the first two speed events at Lake Louise, Canada. On December 27–28, 2019, he won consecutive World Cup downhills in Bormio, becoming the first skier in history to achieve five downhill victories – four in a row – on the Stelvio course. In late January, three days after his first-ever podium on the classic Lauberhorn downhill, Paris suffered an ACL injury during a training session, ending prematurely his season.
