Will the Supreme Court overturn gay marriage?
I assess a modest but non-negligible chance that the Supreme Court will overturn Obergefell and thus marriage equality by 2029 — my independent probability is 10%, higher than the market's 5% but still low given legal, political, and practical constraints.
Analysis
**Stage 1 — Blind analysis (ignore market price):**
- The baseline legal reality is straightforward: Obergefell v. Hodges (2015) currently governs same-sex marriage nationwide. There is no contemporaneous, widely reported certiorari grant or clear lower-court conflict that squarely presents a vehicle for the Supreme Court to reverse Obergefell.
- That said, the Court's behavior since Dobbs (2022) demonstrates that the current conservative majority is willing to revisit and overturn precedent in high-profile areas of constitutional law. The doctrinal path used in Dobbs — emphasizing originalist reasoning and re-evaluating substantive due process precedent — is available as a template to challengers of Obergefell.
- Political and social context matters: public support for same-sex marriage is high (>60–70% in most recent national polls), many states have codified protections, and millions of marriages are on the books. Overturning Obergefell would create significant legal dislocation and political backlash, raising the bar for the Court from a prudential perspective.
- Procedural requirements are central: to overturn Obergefell the Court needs an appropriate case (standing, proper posture, and a legal question framed for overruling). Currently, the news you supplied points to state-level precautionary steps (e.g., Virginia's effort to remove dormant ban language) — these indicate planning for a contingency, not a live certiorari vehicle.
- Considering all of the above, the risk is asymmetric: the Court has shown it will overturn precedent in certain areas, and conservative litigants and states are actively seeking test cases and statutory architectures that could force review. But existing facts — lack of a cert grant, strong popular support, and the complex fallout of an outright reversal — all push the probability down.
- My independent, evidence-based probability that the Supreme Court will overturn marriage equality by 2029 is 10%. This reflects a low baseline probability driven by procedural scarcity and political restraints, tempered upward for demonstrated Court willingness to revisit precedent and the active planning by state actors to create future test cases.
**Stage 2 — Market calibration (now look at market price Yes=0.05 / No=0.95):**
- The market currently prices 'Yes' at 5%. I am higher at 10%. The market's pricing appropriately reflects the absence of an imminent cert grant and the political/administrative friction to overturning Obergefell. Markets tend to anchor to current observable signals (no cert, no major litigation headlines) and heavy public sentiment in favor of No.
- Why I think the market may be underpricing the tail risk: markets often underweight low-frequency, high-impact legal events when there is no immediate paper trail (no cert, no lower-court split). But the legal and political ecosystem can produce a rapid change in price once a vehicle appears — for example, a lower court ruling upholding a state ban, or a cert grant on a rancorous fact pattern could quickly increase the odds.
- Specific reasons markets might be mispricing (supporting a higher independent probability): (1) the Court's demonstrated willingness to revisit precedent post-Dobbs, (2) active state-level contingency planning that increases the supply of plausible future plaintiffs and cases, (3) the non-zero chance of a 2027–2028 litigating vehicle reaching the Court with standing and a narrow question that the Court could use to repudiate or substantially limit Obergefell, and (4) tail risk around potential changes in the Court's composition depending on the 2028 election cycle and retirements.
- How to trade the difference: a rational trader who believes the 10% independent probability could expect the market to reprice materially upward if any of the following occur: a cert petition filing that frames the issue squarely, a split among federal circuits on recognition/definition questions, or explicit signals from conservative legal organizations that a test case is being assembled. Until such triggers appear, the market's 5% is defensible; my 10% primarily reflects a non-zero tail risk premium.
- Bottom line: the market price is not absurdly far from my independent view; it is conservative (low) relative to the nonzero structural risks. I would treat the difference as an expression of market caution and short-term signal scarcity rather than a glaring mispricing — but I would increase conviction if concrete litigation developments emerge.
Arguments
For
- The current conservative majority has already overturned a major precedent (Dobbs), demonstrating institutional willingness to reverse established rulings.
- Conservative states retain dormant constitutional bans and can pass laws or take actions that create litigable conflicts likely to reach the Supreme Court.
- Legal strategies could yield a narrow vehicle that invites the Court to roll back or limit Obergefell on doctrinal grounds (substantive due process/originalist arguments).
- A small but real chance of Court composition changes (retirements, appointments) before 2029 could make overturning more likely.
- If lower courts produce a split on recognition, parental rights, or licensing consequences of same-sex marriage, the Court often steps in to resolve high-profile circuit splits.
Against
- No currently reported certiorari petition or clear lower-court conflict directly challenging Obergefell—procedural prerequisites are absent for now.
- Strong and growing public support for same-sex marriage increases political and reputational costs of an outright reversal, which may act as a deterrent for the Court.
- Practical legal chaos if Obergefell were reversed (thousands of marriages, interstate recognition issues) makes a wholesale overturn less attractive than narrower, incremental rulings.
- Many states and localities have statutory protections or marriage registries that complicate immediate implementation of a reversal, reducing the incentive to act.
- Litigants and advocates on both sides are likely to pursue more targeted strategies (religious exemptions, narrow carve-outs), which can achieve conservative goals without provoking a full-scale reversal.
Key drivers
- Presence or absence of a proper Supreme Court vehicle (certiorari petition, circuit split, standing)
- Supreme Court's institutional appetite to revisit precedent (post-Dobbs precedent behavior)
- State-level legislative and constitutional maneuvers that create litigable conflicts (e.g., bans, non-recognition statutes)
- Public opinion and political backlash (electoral/political costs of overturning a popular right)
- Composition of the Court through 2028 and any retirements or appointments
Risk factors
- A sudden lower-court ruling that supports state bans or declines to recognize marriages, producing a cert-worthy split
- Coordinated litigation strategy by conservative legal organizations to manufacture a clear vehicle
- A change in the Court's composition that increases the number of justices willing to overrule Obergefell
- Underestimation of the Court's willingness to overturn widely-accepted precedent after Dobbs
- Inaccurate public reporting or misinformation (social posts claiming 'official reconsideration' without an actual cert petition)
Scenarios
Best case
A conservative litigating coalition successfully manufactures a clear, well‑standing case (for example, a lower‑court ruling refusing to recognize same-sex marriages under state law producing a circuit split). The Supreme Court grants certiorari, hears the case within the 2026–2028 term cycle, and issues a decision by 2028 that explicitly overturns Obergefell or substantially narrows its reach, leading to legal rollback in some states.
Most likely
No immediate Supreme Court reversal occurs before 2029, but conservative states continue to prepare and file targeted litigation. The Court may issue decisions narrowing aspects of marriage law (religious exemptions, administrative recognition questions) rather than wholesale overturning; the probability of a full overturn remains low but non-zero, concentrated in the event of a high-quality vehicle or Court composition change.
Worst case
The Court leaves Obergefell intact through 2029. State-level dormant bans remain unenforceable, and the political and logistical costs of overturning are judged too high. Efforts like Virginia's cleanup proceed to remove dormant bans without any Supreme Court reversal, preserving nationwide marriage equality.

Who will Trump pardon?
AI15%MKT44%Edge-29HypedI assess a 15% chance that Barron Trump will receive a presidential pardon before Jan 21, 2029 — low because there is no current legal exposure and pardoning a family member carries heavy political cost, but nonzero because presidents can and sometimes do issue preemptive clemency and Trump has shown a willingness to use pardons broadly.
