4% — the median of 6 frontier models, resolving by 2076-10-05.

Answer

Gemini (Google): 4% — Reaching 150 requires either an already alive centenarian living 50 more years or halted senescence proven before 2050. No human has reached 123 years, and biological aging involves systemic failure modes that current therapies cannot fully halt. Interventions to halt human senescence would need widespread Phase III validation and multi-decade safety trials by 2045. Breakthrough whole-body epigenetic reprogramming in primates demonstrating indefinite vitality would markedly lift these odds.

Answer

Claude (Anthropic): 1% — No human has verified a lifespan near 120; reversing senescence at scale by 2050 is biologically implausible. Oldest verified human age is 122; no credible scientific pathway exists to extend this to 150 within ~24-50 years. Halting biological senescence entirely would require breakthroughs far beyond current gene therapy, senolytics, or partial reprogramming research. Even optimistic longevity researchers (de Grey, Sinclair) target modest lifespan extensions, not a jump to 150+ by mid-century.

Answer

GPT (OpenAI): 6% — It turns on whether human rejuvenation can be made safe, repeatable, and deployed decades before 2076. No verified human has exceeded 122 years, so 150 requires a roughly 28-year gain beyond the observed record. Cell reprogramming, gene therapy, and senolytics must clear safety and multidecade efficacy trials, then reach patients by about 2050. I would raise this sharply if a controlled human trial showed durable reversal of multiple aging biomarkers with lower mortality.

Answer

Grok (xAI): 8% — Halting human senescence in 24 years, since no one alive can hit 150 by 2050. No verified supercentenarian is old enough to reach 150 before 2050 even with extreme extension. Mouse-to-human translation plus multi-year trials historically take 15-25 years; current programs remain preclinical. Max recorded lifespan has not risen since 1997; a 2030s human reprogramming trial success would shift odds.

Answer

DeepSeek (DeepSeek): 3% — This needs a verified 150-year-old human by 2076, and no one alive today is even close to that trajectory. The oldest verified human was Jeanne Calment at 122; the record has barely moved in 30 years despite better medicine. Even if senescence were halted tomorrow, the first treated cohort would need ~50+ years to reach 150, pushing resolution past 2076. Animal reprogramming results (e.g., mice) don't yet translate to human lifespan extension, and no human trial has shown reversal of aging.

Answer

Qwen (Alibaba): 1% — No living human can reach 150 by 2050, and halting senescence in 24 years is beyond any credible research timeline. The oldest verified human ever lived 122 years; anyone reaching 150 by 2050 would need to have been born before 1900 and still be alive today. Even the most aggressive longevity researchers (e.g., Altos Labs, Calico) target partial age-reversal, not full senescence arrest, with no demonstrated human results. Life expectancy as a population metric sits at ~85 in the best countries; jumping to 150 requires eliminating nearly all mortality, which has no plausible pathway by…
