One prediction market prices this story:

  • California — the market puts it at 98%, closing 1 Nov 2026. The market resolves to Yes if the California legislature adopts new congressional district maps between now and November 1, 2026. It resolves to No if no such adoption occurs by that deadline. Readers often mistake the linked story about child marriage for the resolution criteria, but only the legislative action on district maps matters.
