This market resolves YES if South Dakota Amendment L (An Amendment to the South Dakota Constitution Requiring that a Proposed Constitutional Amendment or Revision Receive an Affirmative Vote of Sixty Percent of the Votes Cast.) is approved by voters at the November 3, 2026 general election under its official approval rule: Simple majority of votes cast on the amendment (S.D. Const. art. XXIII); L itself needs only a simple majority Only the November 3, 2026 vote counts; earlier votes on similar proposals do not. YES means voter approval at this election, not that the measure is later implemented. What the votes mean (official summary): YES: Adopts the amendment; future amendments need 60% (AG pamphlet). NO: Leaves the Constitution as it is; majority approval continues (AG pamphlet). Results: resolves on the result certified by South Dakota State Canvassing Board. It may resolve earlier once official returns or the Associated Press show the outcome cannot change and no recount is pending; if a recount or certified correction changes the outcome before resolution, the certified result controls. No vote: if the measure is removed from the ballot, a court orders its votes not to be counted, or the vote is postponed beyond November 3, 2026, the market resolves N/A. Later legal challenges: resolution follows voter approval as certified. A court later invalidating, enjoining or delaying the measure does not change the resolution. Starting probability: 50% is a neutral starting seed, not a forecast.
