Following the national championships, Valieva participated in the 2021 Channel One Trophy, a televised team competition organized in lieu of the cancelled European Championships. Selected for the Red Machine team by captain Alina Zagitova, Valieva won both the short program and free skates, helping the Red Machine win the trophy. For her final event of the season she participated in the senior Russian Cup Final, winning the short program by a wide margin. In the free skate Valieva attempted a quadruple Salchow in competition for the first time, but fell on this in addition to making errors on both quad toe loop attempts. As a result, she finished third in that segment, however, she won overall by 2.04 points over teammate Maiia Khromykh due to her higher score in the short program.
