The Sidorova rink was initially selected to represent Russia at the 2018 Winter Olympics, but after their poor play during the 2017–18 season, the Russian Curling Federation was forced to hold a best-of-seven Olympic Trials between Team Moiseeva and Team Sidorova to see who would represent the "Olympic Athletes from Russia" team at the Olympics. Team Moiseeva won the series four games to one, earning them the Olympic spot. At the 2018 Winter Olympics in PyeongChang, South Korea, the team struggled, finishing in a dismal ninth place with a 2–7 record. Team Moiseeva also represented Russia at the 2018 World Women's Curling Championship where Portunova played third on the team. They had a much stronger tournament at the World's, qualifying for the playoffs with a 7–5 round robin record and defeating the United States to win the bronze medal.
