Hasselborg's rink was selected to represent Sweden at the 2018 Winter Olympics. In the lead up to the games, the team took home another silver medal at the European Championships, losing in the final of the 2017 European Curling Championships to Eve Muirhead's team from Scotland. A few months later at the Olympics, Hasselborg led her team to a 7-2 round robin record, in second place behind the host Korean "garlic girls" team, skipped by Kim Eun-jung. In the playoffs, Hasselborg knocked off the Muirhead-led British rink in the semi-final, before beating South Korea in the final to win the gold medal. A month later, Hasselborg skipped the Swedish national women's team at the 2018 World Women's Curling Championship, falling to the Canadian team in an extra end in the final, to take home the silver medal.
