final rationale
Mean of 5 draws (0.65, 0.66, 0.67, 0.67, 0.64). (0) Nothing is resolved yet. The resolution source (srbija.gov.rs) shows no new PM election, and the parliamentary vote is not until 25 October 2026. Đuro Macut remains caretaker PM. (a) The rules give a deadline of 30 June 2028, about 20 months away, so even a slow 4-6 month formation like 2022 or 2023 fits easily. Trading closes on 25 October. (b) Status quo: Vučić resigned the presidency on 27 September specifically to run as the United Serbia PM candidate. If his list wins as SNS lists have since 2012, the Assembly is expected to elect him, possibly within weeks, as with Macut in 2025. (c) NO: independent polls (CRTA July 45-36, BIRODI around 48-39) show the Student List ahead. A Student List plurality and government, a deadlock, or a disputed result could keep Vučić out. A health event or substitution of another SNS figure as PM would also resolve NO. (d) YES: a fragmented opposition across seven-plus lists, a 112-seat SNS baseline, and coalition partners (SPS, minority parties) give United Serbia a path to 126 seats. Vučić has already announced a 12-minister cabinet. My decomposition starts from the sibling 'most seats' market at 64% for United Serbia. I take about 92% conversion to PM given an SNS plurality, plus about 15% chance he still forms a coalition if he trails. That gives roughly 0.64, close to the Polymarket anchor of 66.65%. The same-topic Kalshi market (61%, wide spread) also sits near this. I shade slightly below the anchor but find no strong unpriced information.

Planner reasoning
This is a Polymarket question, so polymarket_direct is the price anchor and resolution_source is required (credible reporting, with the Serbian government as fallback). Vučić's term as president runs until 2027, and there has been talk of him switching to the PM role, so Wikipedia background on Serbian elections and the government, plus related markets on Serbian elections, will help triangulate. GDELT adds niche Serbian news headlines on whether he plans to become PM.

Research loops, bottom lines
- current state: As of October 4, 2026, Vučić has resigned the presidency specifically to pursue the premiership, is the SNS's formally declared PM candidate, and polling (albeit divergent depending on pollster) still gives SNS a plausible path to a majority or plurality in the October 25 vote; however, no election has occurred yet, no new government has been formed, and a resurgent Student List creates genuine uncertainty about whether SNS secures a majority sufficient to install Vučić as PM before the question
- base rate: The outside-view/base-rate pattern since 2012 strongly favors the nominee of whichever list wins the election eventually being confirmed as PM (with a typical 4-6 month lag for government formation), and Vučić is the explicit SNS nominee for this role; however, this cycle is unusual in that independent polling (CRTA/Stanford, BIRODI) for the first time since SNS took power shows the opposition Student List leading, which breaks the historical pattern of guaranteed SNS plurality and injects real
- yes case: The strongest YES path is mechanically simple and well-precedented: if Vučić's "United Serbia" list wins a plurality/majority on October 25 — plausible given opposition fragmentation, Vučić's own minority-party coalition strategy, and the pre-dissolution 112-seat SNS baseline — the Assembly is expected to elect him PM, and the 2025 Macut precedent shows such investiture can be completed in under a month, comfortably within the market's June 2028 deadline and even within the market's own Oct 25,
- no case: The NO case rests on three independent, non-trivial failure paths — an outright opposition/Student List win (live per divergent independent polling and 59% distrust of government), a contested/annulled or deadlocked result triggering prolonged crisis beyond the market's practical attention span, or a personal disqualifying event (health, withdrawal, intra-coalition substitution) given that the entire plan is a "one-man show" with no clear SNS backup for the premiership itself.

(washingtontimes.com)
- [2026-10-04] Currently incumbent PM Đuro Macut (independent, nominated by Vučić in 2025) remains in office in a caretaker capacity pending the election outcome; he is not a candidate expected to continue post-election.

(bloomberg.com)
- [2026-10-02] Pre-election monitoring (CRTA/civic groups) reports ongoing irregularities:
the past seven days have been marked by Aleksandar Vučić's resignation as President, the process of granting pardons to 49 individuals without following the legally prescribed procedure, the identification of a large number of phantom voters, bot attacks targeting the media, and violence and incidents in the streets of Belgrade and Novi Sad.
(gradjanske.org)
- [2026-09-22] Press-freedom watchdog CPJ documented rising attacks on journalists ahead of the vote:

(eualive.net)
- [2026-10-02] Pre-election polling is sharply divergent: a government-aligned pollster shows SNS well ahead, while an independent pollster showed the Student List leading.
The latest September Faktor Plus survey, conducted by an agency close to the regime, gives SNS 48.6 percent and the Student List 37.1 percent, while the independent CRTA survey from June 2026 put the Student List ahead at 31.5 percent compared with 25 percent for SNS.
(veridica.ro)
- [2026-09-26] Analysis frames three possible election outcomes determining whether Vučić becomes PM:
SNS majority and Vučić as PM; SNS first without a stable majority; or a student/opposition surge.
(eurasiareview.com)
- [2026-10-04] By law/constitution, the 250-seat Assembly election is decided by proportional representation (3% threshold); a PM must be elected and sworn in by the new Assembly after the vote — this has not yet occurred as of today, with the election itself 21 days away and government formation/swearing-in to follow afterward.
BOTTOM LINE: As of October 4, 2026, Vučić has resigned the presidency specifically to pursue the premiership, is the SNS's formally declared PM candidate, and polling (albeit divergent depending on pollster) still gives SNS a plausible path to a majority or plurality in the October 25 vote; however, no election has occurred yet, no new government has been formed, and a resurgent Student List creates genuine uncertainty about whether SNS secures a majority sufficient to install Vučić as PM before the question's 2028 deadline.
NOT FOUND: No official Republic Electoral Commission results exist yet (election is Oct 25, after the question's current "today" date of Oct 4); no confirmation of post-election government formation timeline or coalition talks; no independent, non-regime-aligned poll from within the final two weeks of the campaign.
report: base rate
- [2026-10-04] Historical base rate: every Serbian government since 2012 under SNS dominance has eventually seated the SNS-nominated PM candidate once that party/coalition won a parliamentary majority; e.g., after the 2022 election SNS took six months of negotiations before forming government in October 2022 with Brnabić, and after the 2023 election it took over four months (17 Dec 2023 election to 2 May 2024 swearing-in of Vučević). https://freedomhouse.org/country/serbia/freedom-world/2023
- [2024-06-10] After the December 2023 election, Vučić did not appoint a PM-designate until 30 March 2024, and the new cabinet was only voted in by the Assembly on 2 May 2024 — roughly 4.5 months of post-election negotiation before a PM was sworn in.
After December 2023 elections, in May 2024 Serbia finally got new government. First President of Serbia Aleksandar Vučić appointed Miloš Vučević as Prime Minister-designate on 30 March 2024.
- [2023-10-?] Freedom House's account of the 2022 cycle shows an even longer lag:
Brnabić was reelected prime minister in October 2022, following a six-month delay in forming a government after the April elections.
This is the relevant reference class for "how long does it take a winning SNS list to actually seat its PM" — consistently 4-6 months, not weeks.
- [2026-09-28] Vučić resigned as President on 27/28 September 2026 specifically to become a prime-ministerial candidate, confirming he is not currently constitutionally eligible to hold both posts and must go through the parliamentary nomination/election process like his predecessors.
Serbia's populist President Aleksandar Vucic resigned Sunday to pursue a bid to become prime minister in an upcoming early parliamentary election... he was resigning to lead his right-wing Serbian Progressive Party in the Oct. 25 ballot.
- [2026-10-03/04] Reporting frames the outcome as contingent on the election result:
If the SNS wins a majority of seats, the parliament is expected to elect Vucic as prime minister.
This is the standard "winner nominates PM" pattern seen in 2012, 2014, 2016, 2020, 2022 and 2023 cycles — i.e., historically, when SNS/Vučić's list has won a majority, its chosen figurehead was always eventually confirmed as PM.
- [2026-09-?] Polling is split along partisan lines, which is itself typical of the SNS-era reference class (government-aligned pollsters consistently show much larger SNS margins than independent pollsters).
the latest September Faktor Plus survey, conducted by an agency close to the regime, gives SNS 48.6 percent and the Student List 37.1 percent... The independent CRTA survey from June 2026 tells a very different story, putting the Student List ahead at 31.5 percent compared with 25 percent for SNS.
- [2026-07-15] An independent CRTA/Stanford poll published mid-July 2026 was the first to show the opposition Student List ahead:
found that among decided voters, 44.9% would support the Student List, compared with 35.7% for President Aleksandar Vučić's SNS.
This is a notable break from the historical pattern in which SNS/Vučić-aligned lists have won every parliamentary election since 2012.
- [2026-08-30] A separate BIRODI estimate (reported ~34 days before Oct 4, i.e. early September 2026) showed an even larger opposition lead:
The SNS-Aleksandar Vučić list would receive approximately 1,593,000 votes or 38.6 percent
versus a Student List lead near 48.5%. This is an outside-view data point suggesting the SNS "automatic win → automatic PM" base rate may not hold this cycle, unlike 2012-2023.
- [2026-09-22] A sibling prediction market tracking the seat-share question ("Will Vučić–United Serbia win the most seats") was priced around 65% in late September 2026, i.e., treating a Vučić-list plurality as more likely than not but with real downside risk versus the Student List.
Aleksandar Vučić – United Serbia leads at 65%, ahead of Student List – Students Win at 35%... The market currently prices the SNS-led United Serbia alliance at 65.0% percent
- [2026-10-04] Even conditional on an SNS/United Serbia plurality, base-rate precedent (4-6 months of post-election negotiation in 2022 and 2023) implies that formal parliamentary election and swearing-in of Vučić as PM would likely not occur until roughly Q1-Q2 2027, well after the market's October 25, 2026 close, though well before the question's actual June 2028 deadline.
- [2026-10-04] No historical instance was found of a losing or second-place list's nominee becoming PM in this era; SNS has controlled the premiership nomination continuously since 2012, making "incumbent bloc's nominee eventually becomes PM" the dominant base-rate pattern whenever that bloc wins a plurality/majority.
BOTTOM LINE: The outside-view/base-rate pattern since 2012 strongly favors the nominee of whichever list wins the election eventually being confirmed as PM (with a typical 4-6 month lag for government formation), and Vučić is the explicit SNS nominee for this role; however, this cycle is unusual in that independent polling (CRTA/Stanford, BIRODI) for the first time since SNS took power shows the opposition Student List leading, which breaks the historical pattern of guaranteed SNS plurality and injects real uncertainty not present in prior cycles.
NOT FOUND: No official, non-partisan exit poll or final pre-election poll aggregate for the October 25, 2026 vote; no confirmation of how quickly a new National Assembly would convene or elect a PM in this specific cycle; no statement from Polymarket, Lines.com or other bookmaker specifically on the "PM by 2028" contract's own pricing (excluded per instructions).
report: yes case
YES means: Aleksandar Vučić is elected by the National Assembly and formally sworn in as Prime Minister of Serbia, resulting in a new government, before June 30, 2028.
- [2026-10-04] Wikipedia's live election page confirms the mechanics most favorable to Vučić: the Assembly has
25 October 2026. All 250 seats in the National Assembly, 126 seats needed for a majority
, and the pre-dissolution SNS-led bloc ("AV–SNSDS") already held 112 seats under Vučić's own leadership, putting it closer to a majority than any rival list.
- [2026-10-02] An independent opinion piece reports Vučić's explicit coalition-building strategy for crossing the 126-seat threshold even without an outright SNS majority:
Vučić, for his part, is counting on assembling a parliamentary majority with Ivica Dačić's Socialist Party of Serbia and the parties representing national minorities which are elected by a different set of privileged rules.
This gives Vučić a plausible majority path even on weaker SNS vote shares.
- [2026-10-02] The same analysis frames the likeliest realistic scenario as SNS winning a plurality and governing via coalition rather than needing an outright majority:
the actual conflict is poised to play out during the high-stakes interval between the parliamentary and presidential votes
is preceded by its own observation that
if the Student List does not lead the parliamentary race, the protests that follow are unlikely to have the same momentum as they would if it wins the largest share of the vote but Vučić nevertheless manages, through coalition-building and electoral maneuvering, to secure enough mandates to form a government
, i.e., even a narrow SNS win plausibly converts into a governing majority.
- [2026-10-03] Vučić is behaving as a government-in-waiting, not a mere candidate: at the Belgrade Arena rally he publicly announced his cabinet structure and conditions for taking office, saying
there will be 12 ministers and a prime minister in the new Government of Serbia... I will not accept to be the prime minister in a government of rotten compromises, where each party must have two or three ministers. Instead of 31 ministers, there will be only 12 ministers and the Prime Minister.
This level of specific governing-plan detail signals confidence in an imminent, successful path to the premiership rather than hedging against defeat.
- [2026-10-04] Reuters/AP reporting corroborates the straightforward constitutional mechanism required for YES:
Vucic, who is constitutionally prohibited from running for a third term as president, declared upon resigning that he would lead his populist Serbian Progressive Party in the parliamentary election. If his party wins a majority of seats, the parliament is expected to elect Vucic as prime minister.
- [2025-04-16] Crucially for timing within the question's window, the most recent government-formation precedent was far faster than the 2022/2023 cycles cited elsewhere: Vučević's resignation was acknowledged on 19 March 2025, Macut was nominated as mandate holder on 6 April, and
the cabinet of Đuro Macut was formed on 16 April 2025, following the latter's election as Prime Minister of Serbia by the National Assembly on the same day
— under one month from resignation-acknowledgment to swearing-in. This shows SNS-controlled assemblies can seat a new PM in weeks, not months, when the party already holds a working majority, undercutting any assumption that formation must take until 2027.
- [2025-04-16] That same investiture vote shows how comfortably an SNS-anchored coalition can clear the 126-seat threshold:
Required majority → 126 out of 250; Yes 153/250; No 46/250
, with the Alliance of Vojvodina Hungarians and United Serbia confirming support in advance — demonstrating the minority-party "privileged rules" leverage Vučić is again counting on for 2026.
- [2026-10-04] The coalition's own branding and structure show continuity and institutional readiness: the "Aleksandar Vučić – United Serbia" list already
included SPO, DHSS, and Social Democratic Party of Serbia (SDPS)... Prior to the 2026 Serbian parliamentary election, the SNS-led coalition was renamed to "Aleksandar Vučić – United Serbia." SNS unanimously nominated Aleksandar Vučić, the president of Serbia, as candidate for Prime Minister and head of the United Serbia electoral list
, meaning there is no intra-coalition leadership dispute to slow down post-election formation — the nominee and junior partners are already locked in before the vote.
- [2026-10-04] A sibling market tracking the seat-share question still prices a United Serbia majority above even odds, with analysts citing structural factors (opposition fragmentation across
Aleksandar Vučić's SNS has won four consecutive early elections since 2012, each time benefiting from a fragmented opposition that could not consolidate in time. The current field features at minimum seven competing lists. The math doesn't lie: when votes scatter across seven thresholds, the largest single bloc wins seats at a disproportionate rate under Serbia's proportional representation rules
) that favor an SNS-led majority outcome, the single necessary precondition for Vučić's installation as PM.
BOTTOM LINE: The strongest YES path is mechanically simple and well-precedented: if Vučić's "United Serbia" list wins a plurality/majority on October 25 — plausible given opposition fragmentation, Vučić's own minority-party coalition strategy, and the pre-dissolution 112-seat SNS baseline — the Assembly is expected to elect him PM, and the 2025 Macut precedent shows such investiture can be completed in under a month, comfortably within the market's June 2028 deadline and even within the market's own Oct 25, 2026 close window.
NOT FOUND: No official Republic Electoral Commission results (election is Oct 25, after today's Oct 4 date); no confirmed post-election mandate-consultation calendar for 2026 akin to the dated steps found for 2024/2025 cycles; no independent final-week poll beyond the June 2026 CRTA survey and September Faktor Plus survey already cited.
report: no case
YES means: Aleksandar Vučić is elected by the National Assembly and formally sworn in as Prime Minister of Serbia, resulting in a new government, before June 30, 2028.
- [2026-10-02] Independent, non-regime polling remains genuinely unresolved:
estimating support for the new political force is challenging due to the scarcity of reliable opinion polls, with a July CRTA poll indicating the Student List could secure 45% of the vote, compared to 36% for the SNS-led coalition
, directly contradicting the government-aligned Faktor Plus numbers and showing a plausible path to an SNS defeat, which would mean no Vučić premiership at all. (osw.waw.pl)
- [2026-10-02] Trust data reinforce the opposition case rather than SNS dominance:
according to the spring Eurobarometer survey, 59% of Serbians do not trust the current government, while 39% do
, a structural headwind for an SNS majority large enough to instal Vučić. (osw.waw.pl)
- [2026-10-02] A credible, non-SNS analytical outlet frames a hung or contested outcome as a live possibility, not a tail risk:
three outcomes are plausible. An SNS majority would return Vucic as prime minister and preserve existing policy
— implying the other two outcomes (opposition win or contested result) do not produce a Vučić premiership. (geopoliticalmonitor.com)
- [2026-10-02] Even the "SNS wins" branch carries execution risk: the same analysis notes a third, contested-result scenario tied to documented post-vote violence precedent, where "a disputed count would likely renew street protests and delay decisions," raising the chance of a protracted crisis rather than a clean swearing-in. (geopoliticalmonitor.com)
- [2026-09-28] Serbia's own leading foreign-policy think tank (OSW) frames Vučić's whole maneuver as resting on one person with no fallback:
the ruling camp lacks a prominent candidate capable of securing victory in the presidential election... this reflects the model developed over the years, involving centralisation of power in Vučić's hands
— a single-point-of-failure structure where any incapacitation, scandal, or withdrawal of Vučić personally (not just an SNS loss) stops the premiership plan with no SNS "Plan B" ready to step in as PM instead. (osw.waw.pl)
- [2026-10-02/2026-09-28] Vučić has a documented cardiac history: he was hospitalized for chest pain and high blood pressure in the US in 2025, with his own cardiologist noting "similar problems" over the prior decade and that resuming "regular activities" was "unrealistic" in the short term — a concrete, recurring personal-health risk to a single 56-year-old figurehead whose premiership plan depends entirely on him personally winning, being elected, and being sworn in. (thepeninsulaqatar.com, tass.com)
- [2026-10-02] Hard external deadlines stacked right after the vote could destabilize any new government before it is fully seated:
several of the country's most sensitive external arrangements, including a US sanctions license for its only oil refiner and a gas supply deal with Russia, expire within weeks of the vote
, creating a plausible crisis window (oil/gas supply shock) in the exact period government formation is supposed to occur. (geopoliticalmonitor.com)
- [2026-09-28] Base-rate "losing-protest" precedent is directly on point and shows irregularities/annulment campaigns have never actually blocked an SNS-declared winner, but it also shows the opposition's standard playbook (street protests, hunger strikes, international-investigation resolutions) will recur regardless of outcome, and this time is explicitly tied by OSW to
an increase in electoral irregularities observed in recent years
, raising (not lowering) the odds of a disputed, internationally-contested result that delays or derails formal government formation. (osw.waw.pl)
- [2026-10-02] The EU has conditioned its own engagement on the vote's legitimacy: EU Enlargement Commissioner Marta Kos told the European Parliament in September that further Serbian EU progress "depends on the next government" and that Brussels "expects a free and fair vote," meaning a widely-perceived-as-fraudulent SNS win could trigger international non-recognition dynamics that complicate (though not legally block) Vučić's path to the PM chair. (geopoliticalmonitor.com)
- [2026-10-04] Resolution-criteria technicality: the market requires Vučić be "elected by the National Assembly and... formally sworn-in," and explicitly excludes any interim/caretaker premier; if the Oct 25 vote produces a hung parliament (as happened in Belgrade's 2023 city election, a
hung parliament, considering that no side had a majority to form a government
) national-level coalition talks could drag on, and if talks fail or produce a different compromise PM (precedent names floated for other offices include Dačić, Vučević, Macut, Brnabić), Vučić personally may never be the one actually elected and sworn in even if "his" bloc nominally wins a plurality. (en.wikipedia.org)
BOTTOM LINE: The NO case rests on three independent, non-trivial failure paths — an outright opposition/Student List win (live per divergent independent polling and 59% distrust of government), a contested/annulled or deadlocked result triggering prolonged crisis beyond the market's practical attention span, or a personal disqualifying event (health, withdrawal, intra-coalition substitution) given that the entire plan is a "one-man show" with no clear SNS backup for the premiership itself.
NOT FOUND: No polling conducted in the final two weeks before October 25; no reporting of any concrete SNS contingency/backup PM nominee specifically for the premiership (as opposed to the presidency); no confirmation of Vučić's current health status beyond the 2025 hospitalization.

(0) Nothing is resolved yet. The resolution source (srbija.gov.rs) shows no new PM election, and the parliamentary vote is not until 25 October 2026. Đuro Macut remains caretaker PM. (a) The rules give a deadline of 30 June 2028, about 20 months away, so even a slow 4-6 month formation like 2022 or 2023 fits easily. Trading closes on 25 October. (b) Status quo: Vučić resigned the presidency on 27 September specifically to run as the United Serbia PM candidate. If his list wins as SNS lists have since 2012, the Assembly is expected to elect him, possibly within weeks, as with Macut in 2025. (c) NO: independent polls (CRTA July 45-36, BIRODI around 48-39) show the Student List ahead. A Student List plurality and government, a deadlock, or a disputed result could keep Vučić out. A health event or substitution of another SNS figure as PM would also resolve NO. (d) YES: a fragmented opposition across seven-plus lists, a 112-seat SNS baseline, and coalition partners (SPS, minority parties) give United Serbia a path to 126 seats. Vučić has already announced a 12-minister cabinet. My decomposition starts from the sibling 'most seats' market at 64% for United Serbia. I take about 92% conversion to PM given an SNS plurality, plus about 15% chance he still forms a coalition if he trails. That gives roughly 0.64, close to the Polymarket anchor of 66.65%. The same-topic Kalshi market (61%, wide spread) also sits near this. I shade slightly below the anchor but find no strong unpriced information.

(0) Not resolved. The election is on 25 October 2026, and the government website shows no new PM election or swearing-in. Vučić resigned the presidency on 27 September to be the SNS-led list's PM candidate. (a) The rules' deadline is 30 June 2028, about 21 months away, which leaves ample time for post-election government formation. The 2025 Macut cabinet was seated in under a month; the 2022 and 2023 cycles took 4-6 months. (b) Status quo: caretaker PM Macut stays in office. Nothing resolves until a newly elected Assembly votes in a PM, and Vučić is the declared nominee of the bloc that has won every election since 2012. (c) NO: independent polls (CRTA/Stanford in July: Student List 45 vs SNS 36; BIRODI also has the opposition ahead) prove right, and the Student List or an opposition coalition seats the next PM. Lesser paths are a deadlocked or contested result where a compromise SNS figure becomes PM, or a health or personal event involving Vučić. (d) YES: SNS wins a plurality, helped by opposition fragmentation, its institutional advantages and partners such as SPS and the minority parties, and the Assembly elects Vučić within weeks or months. The Polymarket anchor is 66.65%, Kalshi's comparable market is about 61%, and the 'United Serbia most seats' market is 64%. A slight premium over the plurality odds is reasonable because SNS could still form a coalition without the most seats, offset by substitution and health risk. I find no unpriced information that justifies moving off the anchor, so I hold about 66%.

The resolving condition is not documented as met: the Serbian government homepage updated October 4 contains no qualifying appointment, while October 3–4 reporting describes Vučić campaigning rather than holding the premiership. There are 21 days until the October 25 election and trading close, but the binding resolution deadline is June 30, 2028, at 11:59 PM ET—approximately 21 months away. If nothing changes, Macut remains caretaker and no qualifying successor takes office, producing the parent market's “Other” outcome and therefore No for this binary contract. I retain Polymarket's 66.65% YES anchor because the research establishes no clearly unpriced development; Kalshi's 61% post-election contract and Polymarket's 64% most-seats contract have different criteria and are context only. The YES scenario is an SNS majority or coalition with Socialists and minority parties electing and swearing in Vučić, whose resignation and explicit candidacy are corroborated by France24 on September 27 and Al Jazeera on October 4. The NO scenario is a Student List-led government or another compromise premier being sworn in first, which defeats this contract even if Vučić subsequently becomes prime minister before the deadline. Electoral uncertainty remains substantial: OSW's October 2 analysis cites July CRTA polling showing roughly 45% for the Student List against 36% for SNS, whereas Veridica's October 2 report cites government-aligned September Faktor Plus polling showing SNS ahead 48.6% to 37.1%, leaving no reliable contemporary consensus. Within the 33.35% NO allocation, I reserve roughly two percentage points for non-electoral failure to complete or establish the qualifying investiture: nomination, de facto control, or caretaker service would not suffice, although historical four-to-six-month formation delays and ordinary official-publication lags should fit comfortably inside the actual deadline.

The condition is not documented as met: the Serbian government's October 4 homepage contains no qualifying investiture announcement, while France24's September 27 reporting and October 3–4 campaign coverage describe Vučić pursuing the premiership. There are 21 days until the October 25 election and trading close, but nearly 21 months until the controlling June 30, 2028, 11:59 PM ET deadline. If nothing changes, Macut remains caretaker and no qualifying successor takes office, triggering the parent market's Other fallback and therefore No for this Vučić contract. I retain Polymarket's 66.65% YES anchor, rounded to 67%, because the research provides no demonstrably unpriced edge; Kalshi's different-deadline contract and the related parliamentary-plurality market are context, not equivalent anchors. YES results if United Serbia obtains a majority alone or with Socialist/minority-party support and Vučić becomes the next Assembly-elected, formally sworn-in premier, consistent with his explicit candidacy and the governing bloc's institutional advantages. NO results if the Student List forms a government or a compromise premier is sworn in first—even if Vučić subsequently becomes PM before 2028. The September Faktor Plus poll reported on October 2 favors SNS 48.6%–37.1%, whereas OSW's October 2 analysis cites July CRTA polling favoring students approximately 45%–36%, leaving substantial uncertainty because the surveys differ in timing and provenance. Historical four-to-six-month formation delays fit comfortably within the deadline, so my 33% No allocation principally reflects electoral and coalition risks, with a smaller allowance for formal-status uncertainty: credible-reporting consensus, or official Serbian information if ambiguous, must establish a qualifying investiture rather than merely a plurality, claimed victory, or caretaker appointment.

(0) The condition has not already been met: the Serbian government website through October 4 reports no National Assembly election or swearing-in of Vučić, so he must still be elected and formally sworn in by June 30, 2028. (a) The parliamentary election is 21 days away on October 25, while roughly 21 months remain until the resolution deadline. (b) If nothing changes, Đuro Macut remains caretaker prime minister and Vučić never qualifies, producing No. (c) No results if the Student List wins, coalition talks deadlock, or an SNS plurality ultimately installs a compromise candidate rather than Vučić; independent CRTA and BIRODI polling showing opposition leads makes this material. (d) Yes results if United Serbia wins enough seats and adds the Socialists or minority parties to reach 126 seats, after which its explicitly nominated candidate Vučić is elected and sworn in. SNS has converted governing majorities into its chosen prime minister consistently since 2012, and historical formation delays of four to six months would still leave ample time before June 2028. I anchor on Polymarket's 66.65% Yes price but apply a modest discount because the latest polling is sharply contradictory, no final independent poll exists, and the related seat-plurality market gives United Serbia only about a 64% chance.
