The World Women's Curling Championships serves as a qualifier for next year's PyeongChang Winter Olympics. Seven teams that have the most qualification points from the 2016 and 2017 World Championships will directly qualify for the Olympic curling tournament. Teams which played in any of the four previous World Championships are eligible to vie for the two other Olympic slots at the Olympic Qualification Event to be held in Pilsen, the Czech Republic.
