Canada's federal election was one of the most-traded political prediction markets of 2025. The combination of a high-profile Liberal leadership transition, a surging Conservative party under Pierre Poilievre, and a compressed campaign period made it a genuine prediction market laboratory.
What the Market Got Right
Prediction markets correctly priced a Conservative seat lead significantly earlier than polling aggregates, reflecting the structural advantage that Poilievre's campaign had built in crucial Ontario ridings. This is a case study in prediction markets outrunning conventional polling analysis.
The Minority Government Market
The most interesting Canadian election market was not "who wins a majority" but "what type of government forms." Minority government probability was chronically underpriced in the first half of the campaign, creating a genuine value position for traders who understood Canadian electoral system dynamics.
Canadian federal elections frequently produce minority governments because of the multi-party system. The base rate is about 60% minority outcomes in the modern era. This base rate was underweighted by most prediction market participants who defaulted to binary thinking.
NDP and BQ as Wild Cards
The NDP and Bloc Québécois's seat outcomes determined minority vs majority outcomes for both major parties. Markets that tracked NDP and BQ seat count predictions were the most analytically demanding — and the most mispriced — because they required regional analysis rather than national polling.
- →Riding-level polling (not just national polls) is essential for Canadian seat prediction markets
- →Quebec markets behave differently from ROC (rest of Canada) — treat them as separate analytical domains
- →Third-party vote splitting creates binary outcome scenarios that require seat modelling, not just vote share analysis
