25% — the median of 6 frontier models, resolving by 2026-11-06.

Answer

Gemini (Google): 28% — Turns on emergency stay applications reaching the shadow docket during the final four weeks before the 2026 midterms. Active post-election day receipt challenges in the Fifth Circuit make emergency docket intervention plausible this month. The Purcell principle heavily disfavors last-minute changes, making summary denials or brief stay orders the most likely vehicles. With only four weeks left before resolution, the tight window keeps the base rate of an official order under one in three.

Answer

Claude (Anthropic): 22% — Hinges on whether a live circuit split or emergency appeal on ballot-receipt deadlines reaches SCOTUS before midterms. No cert grant on mail-in deadlines is currently pending at SCOTUS as of Oct 2026, making a full merits decision unlikely this cycle. Emergency shadow-docket orders on ballot deadlines are plausible close to Nov 2026 midterms, mirroring 2020/2022 patterns, which raises odds above a baseline near zero. A sudden circuit court split or swing-state deadline lawsuit escalating fast in October would be the main trigger to change this estimate.

Answer

GPT (OpenAI): 57% — A late-October emergency appeal is plausible, but no identified case guarantees the Court will intervene before Election Day. State deadline disputes have repeatedly produced emergency applications near federal elections, especially over ballots received after Nov. 3. A party must first lose in a circuit or state supreme court and file quickly enough for merits or stay briefing before Nov. 6. My view would rise sharply if a circuit split or a filed stay application reaches the Court by mid-October.

Answer

Grok (xAI): 18% — An emergency application on receipt cutoffs must already be at the Court or arrive in days. Circuit rulings that trigger Purcell stays typically hit SCOTUS 7-14 days before Election Day; none is public as of 7 Oct. 2020/24 saw multiple mail-deadline orders; 2022 midterms produced almost none, so the base rate for this window is low. A late en-banc extension in PA, WI or MI would reverse the forecast overnight.

Answer

DeepSeek (DeepSeek): 22% — Turns on whether a circuit split on ballot-receipt deadlines ripens into a cert grant or stay application in the next four weeks. The Court has repeatedly declined to take up ballot-receipt deadline cases, most notably denying cert in Republican National Committee v. Pennsylvania in 2024. Any new ruling requires a live dispute with a circuit split or an imminent election deadline forcing an emergency application, and the 2026 midterms give litigants a… The 2020 Pennsylvania and North Carolina emergency orders show the Court will act under election pressure, but only when a state court or federal ruling changes the…

Answer

Qwen (Alibaba): 72% — Election-adjacent SCOTUS emergency orders on ballot deadlines are near-certain in a midterm cycle; the question is timing. The Court has issued emergency orders on ballot receipt deadlines in 2020 (RNC v. DNC, Wisconsin), 2022 (Merrill v. Milligan shadow docket), and 2024 cycles; midterms… With the Nov 3, 2026 general election ~4 weeks away, at least one state deadline case is almost certainly already pending or imminent on the emergency docket. A development that would lower this: if the Court consolidates all such questions into a single merits case held for full briefing, pushing resolution past Nov 6.
