63% — the median of 6 frontier models, resolving by 2027-10-13.

Answer

Gemini (Google): 83% — The 6-3 conservative majority will likely find state-level climate tort claims preempted by federal statute or common law. AEP v. Connecticut and City of New York establish strong federal preemption precedents that this Court is inclined to extend. A decision will easily issue by June 2027 if the Court hears oral arguments during the 2026-2027 October term. Only a narrow jurisdictional remand avoiding the substantive liability merits would prevent a definitive ruling for defendants.

Answer

Claude (Anthropic): 45% — Hinges on whether SCOTUS grants cert and rules on preemption before Oct 2027. SCOTUS has not yet granted cert in a case squarely presenting this issue as of late 2025/2026, so timing to a final merits ruling by Oct 2027 is uncertain. Prior precedent (AEP v. Connecticut, City of New York v. Chevron denials) shows Court's general skepticism toward state common-law climate claims and federal preemption… If cert is granted and case proceeds on expedited timeline, a 6-3 conservative-leaning Court is more likely than not to side with oil industry on preemption grounds.

Answer

GPT (OpenAI): 63% — The outcome hinges on whether a majority treats state tort claims as displaced by federal climate and energy policy. Five justices must favor defendants after certiorari, briefing, argument, and a merits decision before October 13, 2027. The Court has recently been skeptical of expansive climate regulation, but it has also preserved state-law remedies in cases like AEP v. Connecticut. Odds rise sharply if the Court frames emissions as federally governed interstate pollution rather than ordinary state-law deception or nuisance claims.

Answer

Grok (xAI): 72% — SCOTUS grants and holds state climate-damage torts displaced by the Clean Air Act. A 2026-term grant would produce a merits decision by June 2027, well before the 13 Oct cutoff. The 6-3 Court has already cabined climate regulation (West Virginia v. EPA) and displaced federal common-law nuisance (AEP v. Connecticut); oil defendants have sought… Industry win-rate in energy/environment merits cases since 2022 exceeds 70 percent; a cert grant to the cities or a Kennedy-style recusal would be the clearest downward…

Answer

DeepSeek (DeepSeek): 62% — The Court took this case to settle whether federal law displaces state climate tort claims, and this bench is unlikely to let them proceed. The Court granted cert in Suncor v. Boulder to decide whether the Clean Air Act displaces state-law climate damages claims, a question it has signaled skepticism toward. A ruling is expected by June 2027, well before the deadline, so timing is not the binding constraint; the merits are. The conservative 6-3 majority has repeatedly narrowed state tort liability in preemption cases like American Electric Power v. Connecticut, which cuts strongly toward…

Answer

Qwen (Alibaba): 61% — Turns on whether the 6-3 conservative majority treats climate torts as preempted or political questions rather than traditional state-law claims. The current Court has shown willingness to limit expansive liability theories (e.g., narrowing EPA authority in West Virginia v. EPA 2022), suggesting sympathy for… However, state common-law tort claims are historically within state courts' domain, and some conservative justices (Gorsuch, Barrett) may resist creating blanket… A ruling finding political-question doctrine bars these suits or that federal Clean Air Act preempts state tort claims is the most likely pro-industry path; a narrow…
