3 prediction markets price this story:

• Missouri — the market puts it at 1%, with $83 traded in the last 24 hours, closing 1 Nov 2026. The market resolves to Yes if the Missouri legislature adopts new congressional district maps between now and November 1, 2026. It resolves to No if no such maps are adopted by that deadline. Readers often mistake the current court-ordered map as final, but only newly adopted maps count toward resolution.
• Before Nov 3, 2026 — the market puts it at 3%, with $1k traded in the last 24 hours, closing 3 Nov 2026. The market resolves to Yes if the U.S. Supreme Court issues an order allowing Missouri's HB 1 map to govern the November 3, 2026 election before that date. The outcome is No if no such order appears in any relevant proceeding by the deadline. Readers often mistake a lower court ruling for a final Supreme Court decision.
• Republican party — the market puts it at 89%, with $5 traded in the last 24 hours, closing 7 Nov 2029. For the outcome "Yes" to resolve, a Republican must be sworn in as a U.S. Senator from Missouri for the term starting in 2029. For the outcome "No," this specific event does not occur within that timeframe. Readers often mistakenly believe that winning an election or being appointed is sufficient, but only the official swearing-in ceremony counts toward resolution.
