43% — the median of 6 frontier models, resolving by 2027-02-02.

Answer

Gemini (Google): 4% — The S&P 500 is trading near record highs, making a sustained technical bear market by late 2026 extremely improbable. A technical bear market requires a 20% drop that hasn't materialized, leaving almost no room to enter and stay in one by year-end. Historically, entering and remaining trapped in a bear market within a two-month span requires an unprecedented macro shock. A sudden systemic liquidity freeze before December 31 would be the only catalyst capable of forcing a 20% plunge and suppression.

Answer

Claude (Anthropic): 10% — Whether a 20%+ recovery from cycle low happens before year-end 2026 hinges on earnings/rate trajectory over ~14 months. Equity bear markets historically resolve within 12-18 months; by late 2026 this downturn would be well past typical duration. Base rate for S&P 500 staying below a 20% recovery threshold for over a year without any rally is low historically (~15-20%). A recession, Fed policy error, or credit event causing a fresh leg down would be the main thing that keeps this bear market alive through 2026.

Answer

GPT (OpenAI): 18% — It turns on whether a roughly 20% rebound from the cycle low fails to occur over the final eight weeks of 2026. The index must stay below the recovery threshold through Dec. 31; no regulator or vote is needed, only market pricing. Since 1950, drawdowns reaching 20% have more often recovered within months than remained unrecovered at a year-end checkpoint. A renewed recession shock, credit stress, or sharp earnings-cut cycle would most increase the odds of a prolonged bear market.

Answer

Grok (xAI): 72% — Whether SPX can still post a 20% rally off the cycle low in the remaining eight weeks. By 4 Nov the index must already be close to that +20% threshold or else a two-month sprint is required. Historical 20% recoveries inside eight weeks occur in only ~18% of post-peak bear regimes. A late-year Fed pivot or earnings beat could flip it, but the calendar leaves almost no room for a grind.

Answer

DeepSeek (DeepSeek): 68% — Whether the S&P 500 can rally 20% off its low before February 2027, which requires a Fed pivot or earnings rebound. The S&P 500's 2026 drawdown has been driven by a sustained earnings recession and Fed reluctance to cut, not a single shock that typically mean-reverts within months. Historically, bear markets that breach -20% and last past six months have a median duration near 14 months, and this one is already in month 9 with no 20% rally. A decisive Fed pivot or a ceasefire-driven oil drop below $70 would be the most likely catalyst to spark the 20% recovery before February 2027.

Answer

Qwen (Alibaba): 74% — Two months is too short a window for a 20%+ recovery from a cycle low absent a major policy shock. Only ~8 weeks remain in 2026; the S&P needs a rally large enough to close the gap to within 20% of its prior peak, which historically happens in under 2 months in fewer… Even the fastest modern recoveries (March–April 2020) were driven by unprecedented Fed intervention; no comparable catalyst is visible on the near-term calendar. A surprise rate-cut cycle or geopolitical de-escalation producing a 10%+ November–December rally would be the main path to resolution 'No,' but that requires a shift in…
