MIDTERM ODDS EXPLAINED

How midterm
election odds work.

Which 2026 election races are covered?

Compare 2026 Senate election odds, House election odds and governor races by state. We discover open election-winner markets in Polymarket’s midterms collection and look for the corresponding Kalshi event. Coverage reflects available markets, not a complete ballot. Select a state to explore its tracked races.

How are Kalshi and Polymarket election odds compared?

Polymarket supplies its displayed Yes outcome price; Kalshi uses the midpoint of a valid Yes bid and ask. We match explicit party outcomes or exact candidate names. The aggregate is an equal-weight average of available venue prices, without renormalizing outcomes. Review each contract’s settlement rules before comparing.

How often do midterm odds update?

Midterm election odds refresh every five minutes while this page is open. Missing quotes display a dash. A price gap is not a guaranteed trading opportunity. Volume refers to Polymarket’s cumulative event volume only.
