PolyKal stops updating prices before the first polls open and does not report election results. Prices use the same method as the Midterms pages: Polymarket shows the market's displayed Yes price. Kalshi shows the midpoint of the highest Yes bid and the lowest Yes ask when they are within 8¢ of each other, and otherwise the highest Yes bid. Options with no Yes bid show —.
Available from 16 October 2026.
Available from 24 November 2026. Bid, ask, spread, order book depth and open interest for each option.
Available from 24 November 2026. Notes on large price moves, with the facts reported in the same period.
Available from 20 October 2026. One row per option, per day, Polymarket prices only (CSV).
Each platform resolves its market on the official result named in its own rules. The rule text is quoted on this page.
The two platforms have different rules for what counts as winning, different fees, different users and different amounts of money in each market.
Options listed on both Polymarket and Kalshi are compared side by side, in alphabetical order. Options listed on only one platform are shown separately, without a gap figure. The list follows the markets, not an official candidate list.
No. PolyKal stops updating prices before the first polls open and keeps the last pre-election prices as a snapshot. It does not report election results.
Every 15 minutes until prices stop updating before the vote.
