Reading the Massachusetts election markets
These prices describe contracts about the massachusetts governor election, 2026, rather than the share of voters supporting a party. A 60% contract price is not a prediction of a 60% vote share.
Kalshi prices use a valid two-sided bid/ask midpoint. Polymarket prices come from its outcome-price feed. We show Democratic, Republican and any verified independent contracts separately, without forcing the prices to add up to 100%.
History comes from provider time series and observations stored by 567politics. If a provider is unavailable, available stored history is labeled. Missing data stays missing.
