October 10, 2026 — Serbia’s parliamentary election on October 25 is approaching with sharply divergent opinion polls. Now betting and prediction markets offer another way to examine the contest — but their prices must not be confused with surveys of voters or with official election results.
In a screenshot captured on October 10, the prediction platform Polymarket priced Aleksandar Vučić – United Serbia at 61% and Student List – Students Win at 39% in its market for the electoral list that will win the largest number of seats. The snapshot showed approximately $701,357 in cumulative trading volume. Those prices can change from minute to minute.
The numbers do not mean that Polymarket expects the two lists to receive 61% and 39% of the vote. They represent market-implied probabilities of a specific outcome: which list finishes first in seats.
What Serbian bookmaker Meridianbet is pricing
Domestic bookmaker Meridianbet has published over/under markets on the vote shares of individual lists. At the time of Votendi’s October 10 check, the line for United Serbia stood at 45.6% of the vote, with decimal odds of 1.85 for either over or under. The Student List had a line of 39.05%, with odds of 1.80 for over and 1.90 for under.
| Electoral list | Vote-share line | Under odds | Over odds |
|---|---|---|---|
| Aleksandar Vučić – United Serbia | 45.6% | 1.85 | 1.85 |
| Student List – Students Win | 39.05% | 1.90 | 1.80 |
| Ivica Dačić – Factor of Stability | 3.95% | 1.75 | 1.95 |
A line of 45.6% means a bet is settled according to whether the list’s eventual result is above or below that threshold. It is not a declaration that the list will receive exactly 45.6%. Likewise, decimal odds of 1.85 describe the gross return, including the stake, for a successful bet; they are not an 85% chance of success. Bookmakers also build a margin into their prices.
Meridianbet’s seats markets have separate lines: 124.5 seats for United Serbia and 105.5 seats for the Student List. Again, these are over/under thresholds rather than seats already won or official seat projections. Serbia’s National Assembly has 250 seats, and securing a majority requires at least 126.
Polymarket asks a different question
Polymarket is a prediction market: traders buy and sell contracts tied to a defined outcome, and prices are produced by supply and demand. The 61% and 39% shown in the October 10 screenshot refer to the market’s pricing of which list will win the most seats, not each list’s national vote share or seat total.
Under Polymarket’s published resolution rules, the winning electoral list is the one with the greatest number of National Assembly seats. Ties are broken first by valid votes and then, if needed, by the listed names in alphabetical order. The platform identifies Serbia’s Republic Electoral Commission as the final official reference in an ambiguous case.
For example, a list could win the largest number of seats without winning an absolute majority. Winning Polymarket’s “most seats” market is also not the same as forming the next government or becoming prime minister. Polymarket explains that its displayed percentages normally reflect the midpoint between available buying and selling prices, with an exception for wide spreads. Such market prices reflect traders’ positions, not a representative sample of Serbian voters.
Why the betting numbers matter when the polls disagree
Votendi has already documented an unusually wide spread among Serbia’s published national opinion surveys. Its October 5 analysis compared the latest eligible pollster snapshots, finding that the lead margin differs by 20.7 percentage points between CRTA and Faktor Plus.
| Pollster snapshot | Student-list family | United Serbia / SNS family |
|---|---|---|
| NSPM, published Sept. 30 | 44.4% | 41.7% |
| Faktor Plus, published Sept. 21 | 37.1% | 48.6% |
| Nacija, published Aug. 3 | 41.6% | 44.1% |
| CRTA / Stanford DAL, published July 15 | 44.9% | 35.7% |
The gap between these polls is not solved by looking at betting prices. Surveys estimate voter preferences among particular populations at particular times; bookmakers set market thresholds with a commercial margin; and prediction-market contracts trade on a discrete future event. Each measures something different.
Nor should the Meridianbet thresholds be read as a new opinion poll. They provide a separately observable market reference that can be compared with pollster estimates only if the different definitions and incentives are kept clear. In some cases traders may react to surveys, campaign events or perceived turnout effects. The resulting prices do not reveal an independently verified polling sample or methodology.
What will the official results actually decide?
On October 25, voters will cast ballots for electoral lists. The Republic Electoral Commission (RIK) will publish the official results and seat allocation through the legal counting process. Serbia uses a proportional system with the D’Hondt method to distribute 250 seats, subject to the electoral threshold and special rules for national-minority lists.
Until those results are counted and established, no betting line or prediction-market percentage is an actual election result. An official vote-share figure records ballots received; an official seat count records mandates allocated. A market price expresses the current valuation of a future outcome — which can turn out to be incorrect.
Three different signals, one election
Serbia’s election now has three types of publicly observable information: polls reflecting respondents’ stated intentions; bookmaker lines setting thresholds for wagers; and prediction-market prices representing the trading market’s implied probability of a specified winner. The relationship among these measures is informative, but none should substitute for another.
Votendi will continue to show Serbian polling organisations separately rather than impose a potentially misleading average. Readers can compare the source surveys, publication and fieldwork dates and party-list configurations in the Serbia 2026 election hub. When the election is held, the final benchmark will be the official RIK result — not the last price displayed on a betting screen.
