A dramatic reversal on prediction platform Polymarket has become one of the most closely watched developments of Serbia’s election day. The student-backed electoral list moved ahead of Aleksandar Vučić’s United Serbia list in market trading on Sunday, October 25, as voter turnout rose sharply compared with the 2023 parliamentary election.
The shift represents a significant change in market sentiment, but the prices are not election results, opinion polls or exit polls.
Student List overtakes Vučić in Polymarket trading
On Thursday, October 22, the Polymarket market for the winner of Serbia’s parliamentary election showed the following prices:
- Aleksandar Vučić – United Serbia: approximately 68%
- Student List – Students Win: approximately 33%
By Sunday morning, the picture had changed dramatically.
A market snapshot circulating on X showed the Student List at approximately 61%. A separate capture of Polymarket’s main election market placed the Student List at 61% and United Serbia at 40%.
The figures continued changing as trading progressed. In a subsequent midday check, Polymarket displayed the Student List at 53% and United Serbia at 48%.
The market had recorded more than $6.3 million in cumulative trading volume.
The reversal highlights how rapidly sentiment among prediction-market participants can change during an election.

What exactly is Polymarket measuring?
Polymarket allows participants to trade contracts linked to the outcomes of future events.
For Serbia’s parliamentary election, the relevant market concerns which electoral list will secure the greatest number of seats in the 250-member National Assembly.
Contract prices are commonly expressed as implied probabilities, but they are determined by trading activity rather than representative surveys of voters.
This distinction is essential.
A price of 61% for the Student List does not mean that 61% of Serbian voters support the list, nor does it establish that the list will receive 61% of parliamentary seats.
Market quotations may fluctuate significantly because of trading volume, liquidity, new information and participants’ expectations.
The market also measures the largest seat-winning list, not necessarily which political group will ultimately form a government.
Turnout significantly higher than in 2023
The Polymarket reversal has taken place alongside unusually high early voter participation.
According to CeSID and Ipsos, an estimated 27.3% of voters had cast their ballots by 11:00 local time on Sunday, compared with 15.1% at the same point in the December 2023 parliamentary election.
That represents an increase of 12.2 percentage points.
Earlier, election-monitoring organisation CRTA estimated turnout at 19.8% by 10:00, compared with 9.8% in 2023.
The higher turnout has become a central feature of election-day coverage.
However, there is no verified evidence that the rise in turnout caused the change in Polymarket prices.
Higher participation alone cannot establish whether the governing coalition or student-backed opposition is gaining support.
Opinion polls showed a closely contested election
Surveys conducted ahead of the election offered differing pictures of voter preferences.
An Ipsos Strategic Marketing survey published on October 22 reported 47.4% support for the Vučić-led United Serbia list and 40.0% for the Student List.
An NSPM survey published on October 20, by contrast, placed the Student List at 44.5% and United Serbia at 42.7%.
These differences reflect the uncertainty surrounding the contest and underline the importance of comparing polling methodology, fieldwork dates and voter populations.
Unlike opinion polls, Polymarket prices do not measure the preferences of a representative sample of Serbian voters.

Why the election matters
Serbia’s snap parliamentary election follows nearly two years of student-led demonstrations and political tensions.
The protest movement expanded following the November 2024 collapse of the railway station canopy in Novi Sad, which killed 16 people.
The demonstrations brought renewed scrutiny to government accountability, public institutions and corruption allegations.
The Student List is contesting the election against the Vučić-led United Serbia coalition, which has emphasised economic development, infrastructure investment and political stability.
Both competing political programmes and concerns about the integrity of the election have attracted significant attention domestically and internationally.
Market expectations are not election results
Despite the substantial change in Polymarket trading, no conclusion about the electoral outcome can be drawn from the market prices alone.
The relevant contracts will ultimately be resolved according to the election result, with Serbia’s Republic Electoral Commission serving as an authoritative source.
Polling stations are scheduled to close at 20:00 CET (19:00 UTC).
Until official results or clearly attributed independent projections become available, changes in prediction markets remain observations about trading activity rather than evidence of actual votes cast.
Votendi will continue monitoring the election, official turnout figures and the release of results, while distinguishing verified electoral data from opinion polling and prediction-market movements.
