Projection

Lists by number of seats

All 18 lists declared by the Republic Electoral Commission. The faint band is the 90% uncertainty range, the red tick the 3% threshold.

Polls only measure the five larger lists separately; the other values are estimates (see Methodology).

What do the polls say?

National polls published since the 2023 election. Only 2026 polls measuring the current lists count towards the average; earlier ones show the trend.

Odds and ranges

Pollsters differ widely. The figures below come from 1,000 simulated elections: each is a complete 250-seat result in which lists gain at each other's expense.

Seat ranges

Dot: central estimate. Band: 90% of simulations. Dashed red line: 126 (majority).

What would it take?

Pick a list and a seat target — the model works backwards to find the smallest support needed (the other lists keep their relative shares).

All 18 lists can be adjusted and the result updates instantly. Only this section changes — the rest of the page shows the poll average.

Percent of:

The threshold is 3% of all ballots cast (incl. invalid): about 3.08% of valid votes, exactly 3% in “all ballots” mode. Register: 6,450,523 voters (RIK, 10 October 2026). 2023: 58.77% turnout, 2.73% invalid. When turnout changes, minority lists keep the same number of votes.

Coalition builder

Click the lists: which alliance would reach a majority (126) or two-thirds (167, for constitutional change) on the poll average?

What if…

What if the rules were different?

The same vote shares, calculated under eight different allocation rules: the systems of the Hungarian Election Monitor plus three Serbian specifics and the largest remainder method. District-based systems (first-past-the-post, two-round, instant runoff, STV, regional) are not included, because Serbia is a single nationwide constituency and there is no district-level data for the 2026 lists.

Background

Methodology

Serbia elects its 250 MPs in a single nationwide constituency from closed lists. The model's self-check: with the official 2023 votes it reproduces the actual 129 / 65 / 18 / 13 / 13 / 6 / 2 / 2 / 1 / 1 allocation exactly.

Seat allocation

  • 250 seats, D'Hondt: each list's votes are divided by 1, 2, 3…; the 250 largest quotients win seats.
  • 3% threshold of those who voted (including invalid ballots).
  • Minority lists: exempt from the threshold; under 3% their quotient is multiplied by 1.35.
  • Hemicycle: lists are ordered left to right by their political position on Serbian Wikipedia (centre-left–left → centre → centre-right → right). Of the two “big tent” lists, Studentska lista is placed in the centre and Ujedinjena Srbija centre-right.

Poll averaging

  • Recency: exponential decay with a 21-day half-life.
  • Voter register: per the RIK decision of 10 October, 6,450,523 voters (2023: 6,500,666), including 102,147 registered abroad. It may still change slightly until 22 October.
  • Sample size: weight by √sample (1,000 if unknown).
  • House balancing: each pollster gets one vote — the frequently publishing Faktor Plus does not drown out the others.
  • Missing data: if a poll does not measure a list separately, it is left out rather than counted as zero.
  • Withdrawn lists (NPS, ZLF, DS, Kreni-Promeni) and MI–SN, which is not running: removed, with the other values scaled up proportionally.

Estimates and uncertainty

  • Minority lists: modelled as an estimated number of votes (not a percentage), because the number of minority voters is fairly stable: VMSZ about 60,000 (2023: 64,747 parliamentary, 58,295 provincial; shrinking population), SPP about 24,000 (in 2023 still on a joint list with DSHV), SDA, the Albanian and the Russian list with their 2023 vote counts. The percentage follows from turnout; the other lists share the rest proportionally.
  • Small Serbian lists (Karić, Liberalno zelena, Ćale, Gajić): an equal part of the polls' “other” item.
  • Simulation: poll resampling + sampling noise + a shared 3-point “industry-wide error”; minority vote counts ±20%.

The simulation is a mathematical estimate, not a forecast. Serbian pollsters' methodology is not very transparent (according to a 2026 BIRODI analysis, weighting and funding are rarely disclosed), and some houses are accused of bias.

This project was created to analyse Serbia's parliamentary election and visualise different scenarios, as a sister site of the Hungarian Election Monitor. If you have a comment on the model — for example about a new poll, how a list is classified, or the estimated votes of minority lists — please get in touch using the contacts below! The polling data and the methodology are continuously updated. My aim is to give an independent, objective picture of Serbia's electoral process using all available and relevant data: the model combines the latest polls with Serbia's actual electoral rules, and checked against the official 2023 results it reproduces the real seat allocation exactly.
