After a tense build-up to the Olympics, the American won her second straight overall World Cup title on Friday, five races before the end of the season.
Norway's Ragnhild Mowinckel won the race with Germany's Viktoria Rebensburg second.
"That's really exciting, for sure".
"For Wendy, I knew she had a really good run because I could hear the announcers from the top, but I thought 'not today Wendy!'" Shiffrin said, according to U.S. Ski & Snowboard. "To have the overall locked in now before going to Are is pretty cool".
Holdener needed a top two finish to have any hope of keeping the title race alive.
The World Cup continues on Saturday with a slalom in Ofterschwang, followed by one race each of every discipline at the World Cup Finals in Are, Sweden.
