Seidel’s biggest breakthrough came at the Cincinnati Open in August, where she qualified and recorded her first WTA 1000 victory on her debut at that level, defeating Polina Kudermetova in three sets. She followed this with her first win against a top-20 opponent, defeating eighth seed Emma Navarro, and then beat 29th seed McCartney Kessler to reach a WTA 1000 fourth round for the first time. Her run ended against fellow qualifier Varvara Gracheva in three sets, but the performance propelled her into the top 105 in the singles rankings by 18 August 2025.
At the WTA 500 Korea Open, Seidel qualified once again and reached the quarterfinals with a memorable victory over defending champion and sixth seed Beatriz Haddad Maia in a match lasting nearly three and a half hours. The win, in which she came back from 5-2 down in the third set, was the third longest match of the 2025 season. These results helped her reach a new career-high singles ranking of world No. 95 on 22 September 2025.
