45% — the median of 6 frontier models, resolving by 2027-10-14.

Answer

Gemini (Google): 18% — Timing demands rapid cert before judgment or an unusually expedited docket to decide the merits by June 2027. Merits arguments for the 2026-2027 term close by April 2027, leaving barely six months to grant, brief, and decide a case. Courts typically resolve early executive challenges on administrative procedure or preliminary injunctions rather than merits. A direct circuit split would sharply lift odds, but appellate courts rarely diverge from Wong Kim Ark without high court guidance.

Answer

Claude (Anthropic): 32% — Hinges on whether a circuit split or expedited cert push forces SCOTUS to rule on the merits by June 2027. Lower courts have mostly blocked the EO via injunctions, so the case must first reach final judgment and cert grant, which can take 1-2+ years. SCOTUS has historically avoided fast-tracking constitutional blockbusters unless lower courts conflict sharply, and as of late 2025 rulings remained… If the Court grants cert in its current term and sets oral argument for spring 2027, a merits ruling by June 2027 becomes plausible, otherwise unlikely.

Answer

GPT (OpenAI): 58% — A merits case needs to reach the Court quickly enough for the October 2026 or 2027 Term. The Court would need a final appellate judgment or expedited review; emergency-order rulings would not satisfy a merits resolution. Major constitutional disputes often take 1–3 years to reach merits review, making a June 2027 decision plausible but schedule-sensitive. Odds rise sharply if the Court grants certiorari by January 2027 or accepts a direct, expedited challenge to a federal policy.

Answer

Grok (xAI): 71% — SCOTUS grants and decides a merits case on the 14A birthright clause in OT 2026. Trump EO already enjoined; SG will seek cert this Term or next, giving the Court until June 2027 to rule. Major constitutional questions of this type reach merits at ~70% once circuit conflict or nationwide injunction exists. Only a cert denial or further percolation delay would miss the window.

Answer

DeepSeek (DeepSeek): 72% — Whether SCOTUS finishes its merits opinion by late June, not whether it agrees to hear the case. Four circuit courts have split on Trump's 2025 EO; the government's cert petition is already ripe for the 2026-27 term. SCOTUS granted expedited review and set argument for December 2026, so a merits opinion by late June 2027 is the Court's own schedule. Lower-court injunctions already block the EO nationwide, so the issue stays live and not moot; if the Court vacates as improvidently granted or punts on standing, my…

Answer

Qwen (Alibaba): 28% — Requires cert grant in the Oct 2026 term with argument and decision by June 2027—tight but not impossible given active circuit litigation. Multiple district injunctions were issued in early 2025; by now at least one circuit likely has ruled or is close, making cert-eligible by spring 2027. The Court granted cert quickly in Trump v. United States (immunity) and the SB8 case, showing willingness to take explosive executive-power questions fast, but… A single circuit split or a stay application reaching the Court this term would be the development most likely to push this over the threshold.
