How to read this chart

The green line is the TruthIndex™, the chance of this outcome. It combines the prices on both venues and gives more weight to the venue with more money in its order book. The two thinner lines are Polymarket's and Kalshi's own prices, and the grey band between them shows how far apart the two venues are.

The pale bands behind the lines are the rating zones (Toss-up, Lean, Likely and Safe), so you can see when the race moved from one rating to another. Move along the chart, or use the arrow keys, to read the values for each day.

Contract shown: Mary Peltola

If Mary Peltola wins the 2026 Alaska Senate election, then the market resolves to Yes.

For parliamentary elections, the party or coalition with the most seats wins. If two parties tie in seats: the one entering government will resolve to Yes and all others to No. If both or neither enter government, the one with the higher share of the vote will resolve to Yes and all others to No. For coalitions/alliances, only those formally registered with electoral authorities before the nomination deadline count, not post-election governing arrangements. Overhang seats, leveling seats, and appointed seats count only if specified. For referenda/plebiscites, the specified option achieves the required threshold per applicable law (simple majority, supermajority, dual majority, turnout requirements). If multiple thresholds exist (e.g., majority of votes AND majority of states), all must be met. For presidential or direct elections, the candidate who wins according to the electoral system (electoral college, popular vote, or runoff as applicable) and either (i) is inaugurated/sworn in/takes office, or (ii) the scheduled inauguration date passes without a different candidate taking office is the winner. The market resolves based on the official certification or declaration by the relevant electoral authority. Contested results are resolved based on the final certified outcome by the appropriate electoral authority or highest court with jurisdiction. In cases of competing claims (two presidents, disputed succession), the individual recognized by the hierarchical majority of Source Agencies prevails. The market remains open until the rescheduled election or two years from the original date, whichever comes first. Repeated postponements count towards the 2-year deadline. If results are annulled by a court/authority AFTER announcement but BEFORE the winner takes office, the Contract remains open until re-run election or expiration.
