High political polarization ahead of Serbia’s October 25 snap parliamentary election has driven above-average turnout expectations, with the contest between Aleksandar Vučić’s United Serbia list and the student-led opposition list mobilizing both core supporters and previously disengaged voters. Recent large-scale rallies, including a reported 150,000-person student demonstration in Belgrade, alongside sustained protests over governance and corruption issues, have intensified campaign activity and raised participation forecasts. Polling estimates vary notably, from around 65 percent in one survey to nearly 80 percent in another, reflecting uncertainty over how effectively the student movement can convert protest energy into votes versus the ruling party’s disciplined base. Analysts highlight turnout as the decisive variable that could determine seat outcomes under proportional representation, keeping the 62–70 percent bands closely priced as traders weigh mobilization dynamics and potential last-minute shifts in voter engagement.
