Answer

Gemini (Google): 7% — With under four months remaining until his term concludes on January 3, 2027, the window for an early departure is exceptionally narrow. McConnell stepped down from leadership to finish his Senate term as a rank-and-file member, making voluntary resignation strategically pointless this close to the finish line. The primary catalyst would be acute health incapacity or death, but Kentucky's vacancy-filling procedures and his legendary institutional obstinacy incentivize holding the seat to the final gavel. Actuarial mortality and sudden severe incapacitation over a 110-day span for an 84-year-old establish the small baseline probability.

Answer

Claude (Anthropic): 4% — McConnell announced in early 2025 he will not seek re-election in 2026, meaning his term ends January 3, 2027 regardless. This market requires him to leave early, before that date. McConnell, age 84, has had health scares (falls, freezing episodes) but has consistently stated intent to serve out his full term. He's shown no signs of resigning early; senators who plan to retire almost always finish their term unless health crisis or death intervenes. Base rate for sudden resignation/death in a ~4 month window for an elderly senator is low but non-trivial given his health history.》…

Answer

GPT (OpenAI): 9% — Only about 110 days remain, and McConnell has already said he will not seek reelection in 2026 while continuing to serve through the term’s January 3, 2027 expiration. Senators very rarely resign in the final months absent a health crisis, scandal, or a concrete succession advantage; a late resignation would mainly let Kentucky’s Democratic governor set an interim process, reducing partisan incentive. His 2023 freezes and age-related scrutiny raise the health-tail risk, but he has continued in office since. A verified hospitalization or explicit incapacity announcement would change this sharply.

Answer

Grok (xAI): 8% — McConnell already announced he will not seek re-election and will serve out the term ending 3 Jan 2027; with ~3.5 months remaining, an early resignation is near-zero because Kentucky’s Democratic governor would appoint a replacement. Death is the only realistic vacating event. An 84-year-old male’s baseline 3.5-month mortality is ~4 %, modestly elevated by his documented freezes and falls, producing a single-digit chance. No pending health crisis or scandal is public; only a sudden incapacitating event would flip the outcome.

Answer

DeepSeek (DeepSeek): 12% — McConnell already announced in Feb 2025 he won't seek reelection in 2026, so he leaves at term end regardless — the market needs an *early* exit, which is a much narrower event. He is 83 with a history of freeze episodes, but he has publicly committed to serving out the term and has kept voting; no reporting suggests imminent resignation. Historically, senators who announce retirement overwhelmingly finish their terms; early departures usually follow health crises or scandal, neither of which is currently documented. The decisive factor would be a new medical event or leadership deal forcing a resignation, and absent that, the base rate for a sitting senator quitting mid-term in a ~3.5-month…

Answer

Qwen (Alibaba): 12% — McConnell announced in February 2024 he would not seek re-election in 2026, meaning his term naturally ends January 3, 2027. The question asks whether he steps down *before* that date. Senators occasionally resign early to give governors time to appoint successors or for health reasons, but McConnell has shown no public indication of early departure. He's 84 and had a notable freezing episode in 2023, but has remained active. Base rate of senators resigning months before term end is low (~5-10% in comparable windows). Health deterioration is the main wildcard.
