PQ Holds 72% Quebec Election Odds as Poll Lead Persists

Quebec Election Polls Keep the PQ Ahead as Its Odds Hold Near 72%

The Parti Quebecois is priced at roughly 72% to win the October 5 Quebec National Assembly election. That strong implied probability rests on a consistent polling lead, not on anything close to 72% of voters supporting the party. The three most recent public polls place the PQ between 30% and 34% in a fragmented five-party field.

This is exactly where vote share and win probability can look dramatically different. A party can have only one-third of the vote and still be the clear favorite to finish first, especially when its rivals divide most of the remaining support.

At publication, Kalshi quoted the PQ around 70% to 71%, while Polymarket quoted it around 72% to 73%. The average bid-ask midpoint is approximately 72%. The small cross-venue spread is useful: two different trader pools are reaching nearly the same conclusion about the party's chance of finishing first.

The next tier is much lower. The Coalition Avenir Quebec is priced around the mid-teens, and the Quebec Liberal Party is near the low teens. Those prices can change quickly in a provincial campaign, but the PQ currently has a larger market lead than its raw polling lead suggests.

What the Latest Quebec Election Polls Show

Vote-Scope's Quebec polling table lists 70 polls from eight pollsters, with the latest fieldwork ending August 12. The newest Abacus Data survey of 300 adults has the PQ at 34%, the Quebec Liberals at 25%, the CAQ at 23%, Quebec solidaire at 10%, and the Conservative Party of Quebec at 8%.

Two other August polls tell a similar story. Leger measured the PQ at 30%, the Liberals at 24%, and the CAQ at 20% among 998 adults. Synopsis put the PQ at 30%, the Liberals at 26%, and the CAQ at 20% in a sample of 1,040 adults.

The exact margin changes from poll to poll, but the ordering is stable across those three surveys: PQ first, Liberals second, CAQ third. That repeated first-place position is more important to the winner market than whether the PQ is at 30% or 34% in any single poll.

Why 30% to 34% Support Can Produce 72% Win Odds

Quebec's first-past-the-post system converts local riding victories into National Assembly seats. The market is not simply asking whether the PQ wins a majority of the province-wide vote. Traders are assessing whether its support is likely to translate into more seats than every other party.

Fragmentation magnifies the leader's advantage. In the latest Abacus poll, the Liberals and CAQ combine for 48%, but they compete separately. The PQ does not need to beat that combined number. It needs to win more ridings than either party can win on its own.

Consistency also matters. A one-off 34% poll would be weaker evidence than three different pollsters placing the PQ first. The market's 72% price appears to reflect the repeated ordering and the limited time left before October 5, not an expectation that the PQ will receive 72% of ballots.

The Referendum Strategy Is New Campaign Context

The campaign gained a new strategic issue on August 18. The Associated Press reported that PQ leader Paul St-Pierre Plamondon would delay an independence referendum until after Donald Trump's presidential term ends in January 2029, while still pledging a referendum during a first PQ term.

That announcement may reduce the immediacy of the referendum question for some voters, but there is not enough evidence to claim it caused the current market price. The PQ was already leading the August polls. The cleaner interpretation is that the strategy becomes one of the next issues that could either preserve or erode the lead.

The Case Against the PQ at 72%

The PQ is favored, but the polling margins are not insurmountable. The Liberals are only four points behind in the Synopsis poll, and the CAQ reaches 23% in Abacus. A shift of a few points, combined with efficient regional vote distribution, could materially change the seat race.

There is also model risk in translating province-wide support into seats. Parties do not distribute their voters evenly. A party can lead the popular vote while wasting support in safe ridings, and a close rival can outperform its provincial share by winning more competitive seats.

Finally, the latest Abacus sample is only 300 adults. The broader evidence is stronger because multiple pollsters agree, but no single topline should justify a 72% price on its own.

What to Watch Before October 5

Watch whether the Liberals close the gap, whether the CAQ consolidates center-right voters, and whether riding-level projections continue turning a roughly one-third PQ vote share into a first-place seat total. Any new poll that puts another party first would be more consequential than a small change inside the PQ's existing 30% to 34% range.

The market's current message is not that seven in ten Quebec voters support the PQ. It is that a stable polling lead in a fragmented field gives the party roughly a seven-in-ten chance of finishing first.
