56% — the median of 6 frontier models, resolving by 2027-01-01.

Answer

Gemini (Google): 2% — Across a basket of major world leaders, at least one almost certainly resigns, loses an election, or is removed before 2027. Several tracked leaders like Yoon Suk Yeol, Olaf Scholz, and Justin Trudeau face immediate electoral or impeachment perils. Over multi-year horizons, the base rate of at least one turnover among 10+ major world leaders approaches 98-99%. Only unprecedented simultaneous survival across all contested democracies through December 2026 could keep this market intact.

Answer

Claude (Anthropic): 15% — Whether any one of likely many monitored leaders dies, is overthrown, or formally exits before Jan 1 2027. With a short ~2-month window remaining and typically a broad list of leaders tracked, base rate of at least one unexpected death/coup/resignation is non-trivial. Aging leaders, coup-prone regions, and ongoing political crises (e.g., unstable coalitions, health issues) make a zero-event outcome unlikely across a full list. A single confirmed permanent exit (death, coup, formal resignation completing) before Jan 1 2027 flips this to No, and such events are historically frequent across…

Answer

GPT (OpenAI): 24% — The result hinges on whether any monitored leader faces a completed succession in the remaining 66 days. Late-year elections and constitutional handovers routinely produce departures, while deaths, coups and resignations add a small tail risk. A scheduled election result counts only once the incumbent actually leaves office; a caretaker extension delays qualification. I would raise this sharply if the list excludes leaders with imminent post-election or fixed-term transitions, especially before 31 December.

Answer

Grok (xAI): 91% — No unexpected death, coup or effective resignation among tracked heads in the remaining 65 days. Only permanent occupancy end counts; elections, caretakers and 25th-style pauses are excluded by the rules. Annual in-office death or ouster rates for G20-level leaders are ~1-2%; 65 days therefore implies ~0.3% per person. A sudden health event for Xi, Putin or a Gulf monarch would move the number most; none is currently reported as critical.

Answer

DeepSeek (DeepSeek): 88% — The short window and narrow removal criteria make a qualifying permanent exit unlikely before 2027. Only ~2 months remain until 2027-01-01, and permanent removals require a discrete triggering event, not just an election result. Most monitored leaders face no imminent removal mechanism: US impeachment needs 67 Senate votes, France's Macron is term-limited to 2027, and caretaker roles explicitly… The highest-risk cases are Israel's Netanyahu (elections due by Oct 2026) and Brazil's Lula (Oct 2026 election), but both would likely remain in caretaker roles past Jan…

Answer

Qwen (Alibaba): 90% — Only ~2 months remain; permanent removals (coups, deaths) of listed leaders are rare in such short windows. Base rate of permanent removal (coup/death/forced ouster) among major listed leaders is roughly 1-2 per year globally, making a 2-month hit ~5-8%. Electoral defeats, announced resignations, and temporary suspensions are explicitly excluded, narrowing the qualifying events further. A sudden coup in an unstable listed state (e.g., Sahel region, Myanmar) or a leader's death would flip this; no specific imminent signal is public.
