78% — the median of 6 frontier models, resolving by 2027-09-16.

Answer

Gemini (Google): 78% — The index almost always sets records over any ten-month span unless an active recession severely impairs aggregate corporate earnings. Historically the S&P 500 records at least one all-time high in roughly 70-80% of all rolling ten-month windows outside protracted bear markets. A recovery before July 2027 requires corporate earnings growth to absorb interest rates without triggering a sharp spike in US unemployment. A formal Fed-induced credit contraction or prolonged US recession by early 2027 would push recovery past the deadline and invalidate this.

Answer

Claude (Anthropic): 88% — Whether the index has already set new highs by mid-2026, and if not, whether it can recover in the ~1yr window left. Historically, S&P 500 has recovered to new highs within 1-3 years after most pullbacks that aren't accompanied by deep recessions. With a full year (Sept 2026-Jul 2027) plus likely prior gains already baked in from today's date, base rate favors a new high given typical ~10% annualized drift. Main risk is a severe recession, credit crisis, or geopolitical shock causing a prolonged bear market that outlasts the window.

Answer

GPT (OpenAI): 88% — A one-year window is long relative to typical S&P 500 drawdown recoveries, absent a recession or credit shock. Since 1950, the S&P 500 has historically made fresh highs in most rolling one-year periods after non-bear-market pullbacks. Corporate earnings growth and Fed easing or stable policy would usually restore a record close well before July 2027. A sustained U.S. recession, inflation-driven rate hike cycle, or systemic credit event would be the main reason recovery misses the deadline.

Answer

Grok (xAI): 62% — Whether the implied 2026 drawdown fully retraces to a closing ATH by 30 Jun 2027. S&P must print a close above the prior record; that requires earnings growth plus no policy shock in the next 9.5 months. Median recovery from 10-20 % corrections is 4-11 months, so the window sits near the historical base rate. A 2026-27 recession or post-election fiscal surprise would push the high past July and flip the call.

Answer

DeepSeek (DeepSeek): 78% — Whether the current drawdown resolves within roughly ten months, as most 10-20% pullbacks historically do. The S&P 500 needs to reclaim its prior record close, which requires the current pullback to end and a sustained rally to follow. Historically, the median recovery time from a 10%+ correction to a new high is about 4-8 months, and only deep bear markets (2000, 2008) take years. The Fed's rate path and whether earnings growth stays positive are the key swing factors; a recession signal would push this below 50.

Answer

Qwen (Alibaba): 72% — The S&P 500 historically recovers to new highs within 12–18 months of most pullbacks, and this window gives it a full year. Since 1950, the S&P 500 has reached a new all-time high within 12 months of a prior peak roughly 70–75% of the time absent a recession. A full 12-month window (to July 2027) is generous; the main risk is a sustained bear market driven by recession or a major credit event. If the current drawdown is under 20% and no recession is underway, base rates favor recovery; a confirmed recession would drop this below 40%.
