Planner reasoning

Utah's congressional map was redrawn following the Prop 4 litigation, with a district court adopting a new map (Map C) in late 2025 over the legislature's objections; the key uncertainties are appellate outcomes (Utah Supreme Court, possible SCOTUS/emergency stay) and whether the legislature enacts a replacement before candidate filing. The Polymarket price is the primary anchor; news search plus cross-venue checks will identify any late-breaking legal developments.

# Current state Utah is now using a court-ordered new congressional map (Plaintiffs' "Map 1," adopted by Judge Dianna Gibson on Nov. 10, 2025) for the 2026 midterms. The Utah Legislature's Supreme Court appeal was dismissed for lack of jurisdiction (Feb. 20, 2026), candidate filing under the new map closed in March 2026 with 41 candidates filed, and a remaining lawsuit by Reps. Burgess Owens and Celeste Maloy was voluntarily dismissed (July 2026). Primaries per Wikipedia are scheduled June 23, 2026 under the new map, indicating strong resolution toward "Yes." # Timeline of key events - 2025-08-25: Judge Gibson rules Utah's existing map unlawful (violates Prop 4 anti-gerrymandering commission process); orders new map before 2026 filing (confirmed, PBS). - 2025-09-06: Gibson issues amended order (confirmed, KSL, referenced in appeal). - 2025-11-10: Gibson rules Legislature's replacement "Map C" and SB 1011 also violate Prop 4; adopts Plaintiffs' Map 1 instead (confirmed, Democracy Docket). - 2025-12-09: Republican legislators vote to postpone candidate filing deadline to March 9-13, 2026, reportedly to buy time hoping Utah Supreme Court reinstates old boundaries (confirmed, SLTrib). - 2025-12/2026-01: Legislature formally appeals to Utah Supreme Court, challenging Aug. 25/Sept. 6 orders (confirmed, KSL). - 2026-02-20: Utah Supreme Court dismisses Legislature's appeal for lack of jurisdiction (no final judgment yet); court-ordered map stands (confirmed, Utah News Dispatch, KUER). - 2026-03-09 to 03-13: Candidate filing period under new map; closes with 41 candidates filed across four districts (confirmed, Utah News Dispatch). - 2026-06-23: Primary elections held under new map (per Wikipedia, scheduled/confirmed as occurred by article tense). - 2026-07-10: Owens and Maloy dismiss their separate lawsuit challenging the new map (confirmed, KSL/GDELT). # Event Will Utah use a new congressional district map (replacing the 2021 legislature-drawn map) for the 2026 midterm elections? # Outcomes to forecast - Yes - No # Kalshi market anchor No direct Kalshi price returned for this exact ticker in tool output; Kalshi keyword searches ("Utah congressional map," "redistricting") returned no directly matching market, only tangential Utah political markets (Senate 2028, Governor 2028). Polymarket is the clearest available direct proxy: **90.5% YES**, flat over 7 days (+0%), +1% over 30 days, range 68.5–94.5% over 90 days, $93,640 total volume — indicating the market has converged toward high confidence after early-2026 volatility (likely reflecting the Feb. 20 Utah Supreme Court dismissal and March filing confirmation). # Sub-question answers 1. **Status of Map C/new map** — Map C was struck down by Gibson on Nov. 10, 2025 along with SB 1011; she instead adopted Plaintiffs' Map 1, which is the map now in effect and used for 2026 candidate filing and primaries (Democracy Docket, KUER). 2. **Appeals/stays** — Utah Supreme Court dismissed the Legislature's appeal on Feb. 20, 2026 for lack of jurisdiction (no final judgment existed to appeal); a separate Owens/Maloy lawsuit was voluntarily dismissed July 10, 2026. No stay or reversal of the court-ordered map has succeeded (Utah News Dispatch, KSL). 3. **Legislative replacement attempt** — Legislature attempted Map C (rejected by court) and delayed the filing deadline (Dec. 9, 2025) to buy time for a hoped-for Supreme Court reversal, but no successful replacement map or restoration of the 2021 map occurred (SLTrib). 4. **Filing deadline/lock-in** — Filing deadline was postponed to March 9-13, 2026; filing closed under the new map with 41 candidates; primary held June 23, 2026, per Wikipedia — map effectively locked in by filing period. 5. **Market pricing** — Polymarket: 90.5% YES (flat/rising trend). No matching Kalshi-direct price was returned in research; Kalshi keyword search found no exact match market. 6. **Base rate for court-ordered maps surviving to use** — Not directly addressed in research; general pattern in 2026 cycle (e.g., Missouri court allowing new GOP-backed map in Aug. 2026) suggests court-cleared maps close to an election tend to survive absent Supreme Court intervention, consistent with Utah's trajectory. # Key facts (high-confidence, factual) 1. [Democracy Docket] Nov. 10, 2025: Gibson adopted Plaintiffs' Map 1 after striking down Map C/SB 1011. 2. [Utah News Dispatch/KUER] Feb. 20, 2026: Utah Supreme Court dismissed Legislature's appeal; map stands. 3. [Utah News Dispatch] March 2026: Candidate filing under new map closed with 41 candidates. 4. [KSL/GDELT] July 10, 2026: Owens/Maloy dismissed their lawsuit against the new map. 5. [Wikipedia] Primary election held June 23, 2026, consistent with new map in use. # Cross-market signals - Kalshi related: No direct match found; adjacent Utah political markets (Senate 2028 GOP 93%, Governor 2028 Dem 14%) unrelated to redistricting question. - Polymarket: 90.5% YES, stable, moderate volume ($93.6k), suggesting market views outcome as largely settled but not fully certain (some residual litigation/tail risk). - Sportsbook implied: N/A (not applicable to this event type). # Analyst opinions and speculation - [270toWin] Redistricting has shifted District 1 ~40% leftward, now viewed as safely Democratic — implies real-world electoral consequences already being priced by analysts, reinforcing that the new map is operative. - GOP legislators' filing-deadline delay was characterized by SLTrib as a stalling tactic hoping for a Utah Supreme Court reversal that ultimately did not materialize procedurally. # Directional lean per outcome - **Yes** (new map used): Strongly supported — court map adopted, appeal dismissed, filing/primary conducted under new map, competing lawsuit dropped. Only residual risk: an unresolved final-judgment appeal path Legislature could still pursue before November, but no signs of success to date. - **No** (old map retained): Weakly supported — relies on a future successful appeal or emergency stay reinstating 2021 map before November 2026; no evidence found of any pending mechanism likely to achieve this after Feb. 2026 dismissal and completed filing/primary process. # Gaps / unknowns - No live Kalshi-direct price was retrieved for this exact ticker (only Polymarket proxy available). - Unclear if Legislature refiled appeal after a "final judgment" was entered post-Feb. 2026 dismissal; no confirmation of further Utah Supreme Court proceedings before November. - No explicit historical base-rate data on court-ordered map survival rates was returned by research tools. # Calibration anchors - Polymarket price (proxy anchor): 90.5% YES, stable. - Precedent: Missouri's 2026 court-cleared map was allowed to stand for November use (Aug. 2026), supporting general pattern that post-filing, court-affirmed maps proceed to use absent late intervention.

1. Both forecasts converge tightly (0.96/0.97) despite the brief explicitly flagging an unresolved gap: "Unclear if Legislature refiled appeal after a 'final judgment' was entered post-Feb. 2026 dismissal; no confirmation of further Utah Supreme Court proceedings before November." Neither rationale addresses this specific procedural loophole—the Feb. 20 dismissal was for lack of jurisdiction (no final judgment existed), meaning the Legislature could still appeal once a final judgment issues, and neither forecaster explains why that residual path is safely dismissed rather than merely unaddressed by evidence. 2. Both forecasters price above the Polymarket anchor (90.5%) by justifying it as "lagging" the facts, but neither considers that Polymarket's stability at 90.5% over 7 days despite the July 10 Owens/Maloy dismissal (a bullish Yes event) could instead reflect market participants pricing in exactly the unresolved final-judgment appeal risk the brief flags — i.e., the market may be better calibrated than the analysts assume, not lagging. 3. Neither forecast meaningfully distinguishes between "No" scenarios: e.g., a court-ordered emergency stay reinstating the 2021 map vs. resolution ambiguity in how "new map" is defined (what if courts later modify Map 1 again before November — is that still "Yes" under a "new map" or could it trigger definitional disputes?). The brief's own "Gaps/unknowns" section raises "resolution-wording ambiguity," but only Forecast 1 mentions this in passing without adjusting probability distinctly from Forecast 2. 4. The base-rate reasoning is thin in both forecasts — the brief admits "No explicit historical base-rate data on court-ordered map survival rates was returned," yet both forecasters treat the Missouri precedent (a single data point) as sufficient support without acknowledging its limited generalizability (different state, different legal posture, GOP-favorable map vs. Utah's plaintiff-favorable map facing a hostile Republican legislature with an active grievance). 5. Both forecasts effectively treat the question as already resolved (primaries held, filing closed) but the event only formally resolves at the November 2026 general election — neither considers scenarios where administrative or logistical complications (e.g., a mid-cycle map change forced by an unexpected late ruling affecting the general election ballot specifically, as opposed to primary ballots already printed) could still occur between July and November, a ~4-month gap that is not fully covered by "no visible pending mechanism" reasoning. 6. Confidence levels (0.85 and 0.88) are similar to the probability estimates themselves, but neither forecaster explains why their stated confidence is not higher given how one-sided the evidence is (nearly all evidence points to Yes with only speculative tail risk) — this suggests underlying uncertainty about the completeness of the evidence brief itself (e.g., the missing Kalshi price, unclear appeal status) rather than genuine uncertainty about the outcome, which should be flagged explicitly rather than folded into a single confidence number.

96% (86% confidence)

Yes: 96% No: 4%

The new court-ordered map (Plaintiffs' Map 1) is already operative: the Legislature's appeal was dismissed (Feb. 20, 2026), candidate filing closed under it in March 2026 with 41 candidates, the June 23 primary was conducted under it, and the last remaining challenge (Owens/Maloy) was voluntarily dismissed in July 2026. Reverting to the 2021 map for November would require an extraordinary emergency intervention after primaries have already produced nominees in the new districts — practically infeasible under Purcell-type reasoning and with no identified pending motion. The critique's strongest point is the unresolved final-judgment appeal path and the possibility that Polymarket's 90.5% is correctly pricing that risk rather than lagging; I weight this by staying modestly below the two forecasts' near-certainty, but even a successful post-election-cycle appeal would not undo the map actually used in November. Remaining 4% covers that latent appeal route, any late definitional/resolution ambiguity, and gaps in the evidence brief.
