Alexei Eala of the Philippines enters the Birmingham semi-finals as the 37th-ranked player and the favourite at 1.71 decimal odds. The 20-year-old has shown strong grass-court form in this event, defeating Anastasia Charaeva and Priscilla Hon in straight sets before her quarter-final appearance. Eala's recent run includes three losses to higher-ranked opponents in Elena Rybakina, Ons Oliynykova and Ivana Jovic, but her consecutive main-draw victories on grass suggest renewed confidence on this surface.

Rebeka Masarova of Switzerland, ranked 132nd, arrives as an outsider at 2.20 odds but carries genuine momentum into the semi-final. The Swiss player has won four of her last five matches, including consecutive three-set victories over Tamara Martincova and Magdalena Fręch, plus a straight-sets win over Harriet Dart. This marks Masarova's deepest run in Birmingham, and the head-to-head record remains level at 0–0 between these two grass-court competitors.
