Planner reasoning

This is a Kalshi question about SCOTUS overturning Obergefell v. Hodges before 2029. The key drivers are whether any case challenging Obergefell is actually on the Court's docket (e.g., the Kim Davis cert petition), whether cert has been granted or denied, how many justices have signaled willingness to revisit it, and the procedural timeline needed for a merits ruling before Jan 2029. Market prices on both venues plus court docket and news searches will anchor the estimate.

# Current state No case seeking to overturn Obergefell is currently pending before the Supreme Court; the only recent vehicle, Kim Davis v. Ermold, had its cert petition denied on 2025-11-10 without noted dissent from any justice. The market resolves YES only if SCOTUS actually overturns Obergefell before 2029-01-01 — not if states pass resolutions, activists file new suits, or justices make rhetorical statements. # Timeline of key events - 2015-06-26: SCOTUS decides Obergefell v. Hodges, 5-4, establishing nationwide same-sex marriage right (confirmed, Wikipedia). - 2020 (cert denial in earlier Davis case): Thomas and Alito issue statement calling Obergefell a mistake threatening religious liberty, urging future reconsideration (confirmed, law.cornell.edu). - 2022-06: Dobbs v. Jackson decided; Thomas concurrence explicitly urges Court to "reconsider" Obergefell, Griswold, Lawrence (confirmed, Wikipedia/RFMA page). - 2022-12-13: Respect for Marriage Act signed, codifying federal/interstate recognition of same-sex marriage as a backstop if Obergefell falls (confirmed). - 2025-01: Idaho passes House Joint Memorial 1, first state resolution urging SCOTUS to reverse Obergefell (reported, ABC/NBC News). - 2025 (through year): At least nine states (Idaho, North Dakota, Montana, South Dakota, Michigan, others) introduce bills/resolutions targeting Obergefell (reported, Newsweek/ABC). - 2025-11-10: SCOTUS denies cert in Kim Davis v. Ermold "without comment" — no Thomas/Alito dissent statement this time (confirmed, supremecourt.gov, NBC News). Legal experts uniformly call it a weak vehicle lacking votes to grant (Notre Dame's Garnett, other law professors). - Liberty Counsel (Davis's counsel) vows to bring new test cases, framing overturn as "not if, but when" (reported, WKYT). - 2026 (mid-year, per GDELT): Media commentary (WND, Daily Signal, Rawstory) describes a "renewed/invigorated campaign" and intra-GOP disputes over marriage equality, but no new SCOTUS cert grant reported. # Event Will the Supreme Court overturn Obergefell v. Hodges (marriage equality) before January 1, 2029? # Outcomes to forecast - Yes (Obergefell overturned before 2029) - No (Obergefell remains in force through close) # Kalshi market anchor **Current YES price: 7%** (KXOBERGEFELL-29). 7-day change: -1pt; 30-day change: -3pt (declining, consistent with the Nov. 2025 cert denial). Range over 70 days: 5%–15%. Average daily volume: 151 contracts — modest liquidity. This is the consensus to beat. # Sub-question answers 1. **Active case/cert petition asking to overturn Obergefell?** None currently pending. Kim Davis v. Ermold was the vehicle; cert was denied 2025-11-10 (supremecourt.gov, No. 25-125). No successor case has been filed as of latest reporting. 2. **Cert grants/denials since 2024 and justice votes?** Only the Davis denial (Nov 2025), which came without any noted dissent or statement from Thomas/Alito/others — a notable contrast to their 2020 statement urging reconsideration (NBC News, Cornell). 3. **Justices signaling willingness to revisit?** Thomas (Dobbs concurrence, 2022) and Alito (2020 statement) remain the only on-record justices urging reconsideration; neither issued a fresh statement in 2025, suggesting no immediate appetite even from them. No Dobbs-majority justice (Kavanaugh, Barrett, Gorsuch, Roberts) has publicly commented either way on Obergefell's safety (claude_news synthesis). 4. **Time remaining for cert→decision cycle before 2029?** Not directly addressed by research, but structurally: with no cert granted as of Nov 2025, a typical cert-to-decision cycle (12-18+ months) would still allow a case granted in 2026-2027 to be decided before Jan 2029 — timing is not the binding constraint; lack of a qualifying vehicle and votes is. 5. **State legislatures/AGs building test cases?** Yes — at least nine states (Idaho first, Jan 2025, then North Dakota, Montana, South Dakota, Michigan) have passed resolutions or introduced bills urging SCOTUS to reverse Obergefell or restricting licenses (ABC News, Newsweek). These create political pressure but no state has yet produced a clean litigated test case reaching SCOTUS. 6. **Prediction market pricing?** Kalshi prices Yes at 7%, trending down. Polymarket has no matching market (0 hits for "Obergefell," "same-sex marriage," "marriage equality overturn"). # Key facts (high-confidence, factual) 1. [supremecourt.gov] Cert denied in Kim Davis v. Ermold, Nov. 10, 2025, no noted dissent. 2. [NBC News] Denial contrasts with 2020, when Thomas/Alito publicly urged reconsideration. 3. [ABC/Newsweek] ≥9 states have passed/introduced anti-Obergefell resolutions since Jan 2025. 4. [Lambda Legal] As of the survey, no pending SCOTUS case sought to overturn Obergefell. 5. [Gallup via Newsweek] 68% national support for same-sex marriage (May 2025); Republican support down to 41% from 55% peak. 6. [Wikipedia] Thomas's 2022 Dobbs concurrence explicitly invited reconsideration of Obergefell. # Cross-market signals - Kalshi related: "Which SCOTUS justices resign under Trump — Alito" priced 64% (rising), which could matter if Alito's replacement shifts the Court's composition/appetite — but replacement ideology direction is unclear. - Polymarket: No matching markets exist; no cross-market signal available. - Sportsbook implied: N/A (not applicable to this event type). # Analyst opinions and speculation - Legal scholars (Garnett, unnamed law professor) say there were never votes to grant Davis's petition and call it an "unsympathetic" vehicle — suggesting current bench lacks appetite even among conservative justices. - Liberty Counsel and conservative activists frame overturn as inevitable ("not if, but when"), actively seeking new test cases — pure advocacy, not evidence of Court receptivity. - Media (WND, Daily Signal) push narrative of "invigorated campaign" in 2026, but no corroborating cert grant or docket movement reported. # Directional lean per outcome - **Yes**: Supported by Thomas/Dobbs concurrence, sustained state-level resolutions, and activist commitment to new litigation. Opposed by lack of any pending vehicle, no dissent in Nov 2025 denial, high public support, and RFMA backstop reducing urgency. - **No**: Strongly favored — no active cert petition, denial without dissent, weak state test-case pipeline (resolutions ≠ litigation), and consistently declining Kalshi price. # Gaps / unknowns - No visibility into any post-Davis test case currently being assembled by state AGs. - Unknown whether Court composition could change materially before 2029 (Alito resignation market at 64%) and how a replacement would vote. - Court docket tool failed — cannot independently verify absence of other live petitions beyond Davis. # Calibration anchors - Kalshi current YES price: 7% (declining 3pts over 30 days) — anchor. - Precedent: 2020 Davis cert denial with Thomas/Alito statement did not lead to any near-term grant; 2025 denial without any statement is a weaker signal for eventual reconsideration than 2020.

1. Both forecasts jump straight to below-market pricing (3% and 6% vs. 7% anchor) without adequately weighing the note that "typical cert-to-decision cycle (12-18+ months) would still allow a case granted in 2026-2027 to be decided before Jan 2029" — i.e., there's still ~3 years of runway for a new vehicle to emerge, be litigated, and reach SCOTUS, which is longer than either rationale implicitly assumes when they treat the lack of a *current* pending case as near-dispositive. 2. Neither forecast substantively engages with the Alito resignation cross-market signal (64% priced, rising) — if Alito is replaced under Trump before 2029, the brief flags "replacement ideology direction is unclear," but a strategic Trump appointee replacing an aging justice could plausibly increase rather than decrease appetite for revisiting Obergefell; this tail scenario is waved away rather than analyzed. 3. Forecast 1's claim that the required mechanism is "nearly impossible on this timeline" arguably overstates certainty (0.85 confidence, 3% probability) given the brief explicitly lists this as a "Gaps/unknown": "No visibility into any post-Davis test case currently being assembled by state AGs" — nine states have already produced legislative pressure, and neither forecaster models the probability that one of these produces a litigated vehicle within 3 years. 4. Both forecasters treat the absence of a Thomas/Alito dissent statement in the Nov 2025 denial as strong evidence of "no appetite," but the brief also notes this could simply reflect the *unsympathetic* nature of the Davis vehicle specifically (per Garnett) rather than a broader retreat from their 2020/2022 positions — the forecasts don't distinguish "weak vehicle" from "no interest," which matters for how much weight to put on a future, better vehicle. 5. Neither rationale explicitly addresses the base rate for the Court reversing a 5-4 constitutional rights precedent it created only ~14 years prior absent a change in majority composition — Dobbs took ~30 years and required multiple new appointees; this reference class arguably justifies going even lower than 3-6%, yet neither forecaster used it to sanity-check their number, they merely adjusted narratively off the Kalshi anchor. 6. Both forecasts converge suspiciously close to the market (3% and 6% vs 7%) with high stated confidence (0.85, 0.72), but given the "modest liquidity" (151 contracts/day) explicitly flagged in the brief, the Kalshi price itself may be noisy/thin, and neither forecaster discusses whether such thin liquidity should reduce anchoring weight on the market price.

4% (78% confidence)

Yes: 4% No: 96%

With cert denied in Kim Davis v. Ermold in November 2025 without even a Thomas/Alito statement, no successor case pending, and no litigated vehicle in the pipeline (state resolutions are not lawsuits), the mechanical path to overturn before January 2029 requires an extraordinary compression: a new case filed, litigated through lower courts, granted, argued, and decided in ~3 years, plus five votes the current record does not evidence. The critique's strongest point (base rate for reversing a recent 5-4 precedent absent composition change — Dobbs took ~30 years) actually argues for going below the 7% Kalshi anchor, which is thinly traded and likely carries longshot bias. The counterpoints (Alito replacement tail, weak-vehicle vs. no-interest distinction) preserve modest tail risk but don't establish a live pathway. I settle at 4%, between the two forecasts and below the market, reflecting residual uncertainty about unseen test cases and possible composition changes.
