How the contract works
A contract on this market settles at $1 if the Parti Québécois wins the greatest number of seats in the National Assembly after the 5 October 2026 election, and at nothing if any other party finishes first. The price at any moment reflects what buyers and sellers currently think that chance is: a contract trading at 0.30, for example, would imply the market sees roughly a three-in-ten chance of that outcome, not that anyone has predicted the result. Settlement is based on official results published by Élections Québec, and if the election has not taken place by 31 January 2027, the market resolves against a PQ win by default. A position taken now can typically be sold before the 5 October result, at whatever price the market has moved to by then.

How the price has moved
The only pricing available for this market comes from a single venue, Polymarket, where the consensus currently sits at 74% on total volume of $81,295 to date. There is no second venue to compare it against, so no cross-market spread exists to describe, and no published day-over-day or week-over-week move figures are available for this market at this time. That absence of a documented trend reflects the market's limited trading history so far rather than any claim that the price has been stable or volatile.
Analysis
Context
Quebec holds a general election on 5 October 2026, choosing all 125 members of the National Assembly under a single-member riding system. The governing Coalition Avenir Québec (CAQ), led by François Legault since 2018, has spent much of its second mandate losing public support amid economic strain and immigration debates. The Parti Québécois (PQ), the sovereignist party led by Paul St-Pierre Plamondon since 2020, nearly disappeared from the legislature in the 2022 election, winning just 3 of 125 seats despite taking close to 15% of the province-wide vote, a result driven by how thinly Quebec's electoral map spreads sovereignist-leaning support outside its rural and regional strongholds. Since then, the PQ has rebuilt its standing in provincial polling, positioning itself as the main alternative to a CAQ government that has struggled to hold its 2018 and 2022 coalition together, while Québec solidaire and the Quebec Liberal Party compete for the remaining opposition space.
Across the one venue currently listing this market, Polymarket, the consensus sits at 74%, on total volume of $81,295. That volume is modest for a marquee provincial election roughly eight weeks out, and with only one venue quoting a price there is no cross-market spread to check the reading against, which is itself useful information: this is a comparatively thin, single-source market rather than one where multiple independent pools of money agree closely on the number. A single new poll, debate performance or CAQ cabinet shake-up could move a market this size more than it would move a deeper one.
The structural story behind the price is Quebec's electoral geography. In 2022, the PQ took nearly 15% of the province-wide vote but only 3 seats, while Québec solidaire won 11 seats on a similar vote share, because sovereignist-leaning support was spread thinly across many ridings rather than concentrated enough to win them outright. For the PQ to convert a polling lead into the most seats in 2026, that support needs to be geographically efficient — concentrated in francophone, non-metropolitan ridings where it can top a fragmented field — rather than merely large in the aggregate. The CAQ's decline after two terms in office, and the possibility that federalist-leaning voters split between the CAQ, the Liberals and Québec solidaire, is the main mechanism that lets a PQ plurality translate into a seat majority, since Quebec uses single-member ridings decided by whoever finishes first, not proportional representation.
The campaign itself has not yet formally started. Quebec elections typically feature televised leaders' debates in the final weeks before polling day, and past Quebec campaigns, including 2018 and 2022, have shown late movement once debates and get-out-the-vote operations begin. The 74% consensus should be read as a snapshot taken well before that phase, not a forecast that accounts for it.
What moves the probability
CAQ fatigue after two terms
François Legault's government has governed since 2018 and shown signs of eroded support in its second mandate. A weakened incumbent is the single biggest reason a PQ plurality looks achievable, since it widens the opposition vote for the PQ to consolidate.
Riding-level vote efficiency
Quebec's single-member system means the PQ needs its support concentrated in specific ridings, not just large province-wide. The 2022 result, 3 seats on nearly 15% of the vote, shows this can go the other way if support stays too thin across too many ridings.
Splitting of the federalist and centrist vote
If the CAQ, Quebec Liberal Party and Québec solidaire divide the non-sovereignist vote roughly evenly, the PQ can win ridings with a plurality well short of a majority. A consolidation of that vote behind one party would work against the PQ.
Thin, single-venue trading
With $81,295 in total volume on one venue, this market has less depth than many major political contracts, so a single poll or debate moment could move the price more sharply than in a deeper market.
The campaign itself has not started
Formal campaigning and televised debates typically occur in the weeks before an October Quebec election. Past races have shown late swings once that phase begins, which the current price predates.
The case for
- François Legault's CAQ has visibly lost ground after eight years in office, leaving the PQ as the main beneficiary of anti-incumbent sentiment in many regions.
- Quebec's single-member riding system rewards support that is concentrated geographically, and the PQ's base is heavily weighted toward francophone, non-metropolitan ridings.
- If the CAQ, the Liberals and Québec solidaire split the remaining vote in 2026 the way they did in 2022, a PQ plurality in many ridings becomes easier to achieve without a majority of the province-wide vote.
- The PQ has had roughly two years of sustained polling advantage over the CAQ heading into the 5 October 2026 vote, giving it more time to organize and fundraise than in past cycles.
The case against
- The 2022 election showed that a large PQ vote share does not automatically produce a large seat count, since the party won only 3 of 125 seats despite close to 15% of the vote.
- A late consolidation of federalist-leaning voters behind the CAQ or the Liberals, particularly in and around Montreal, could deny the PQ the seat count even if its overall vote share holds up.
- Formal campaigning and the televised debates that typically precede a Quebec election have not yet happened, and past races have shifted meaningfully in their final weeks.
- Total trading volume of $81,295 on a single venue is thin for a provincial election of this size, meaning the current price may not reflect the same weight of information as a more heavily traded market.
What to watch
The formal election campaign for the 5 October 2026 vote will open in the weeks beforehand under Quebec's election law, followed by the televised leaders' debates that Quebec campaigns typically hold in September. New public polling released during that period, any CAQ cabinet or leadership developments, and the final week of get-out-the-vote activity are the events most likely to move this price before Élections Québec certifies the result. If the vote does not occur by 31 January 2027, the market resolves against a PQ win under its own rules.
