Answer

Gemini (Google): 57% — Persistent high mortgage rates through early autumn continue squeezing contract signings ahead of the seasonally soft winter window. NAR releases October sales in late November, reflecting contracts from August and September when 30-year yields hovered above 6.5%. Monthly existing sales fluctuate near decade lows, with month-over-month declines occurring in roughly 55% of releases since 2022. A sharper-than-expected rebound in pending home sales index prints would be the primary indicator flipping this to an increase.

Answer

Claude (Anthropic): 48% — Hinges on whether mortgage rates and seasonal patterns push existing home sales down or up in the next NAR release. Existing home sales have swung month-to-month with roughly 50/50 directional odds historically, no strong persistent trend either way. Elevated mortgage rates near 6-7% continue to weigh on affordability, but recent reports have shown modest sales recovery as rates eased slightly. Seasonal winter slowdown in home sales activity could tilt toward a decline, but base rate for single-month direction stays close to even.

Answer

GPT (OpenAI): 57% — The call turns on whether mortgage-rate pressure outweighs normal monthly volatility in October closings. NAR's next release, likely November 19, will compare October's seasonally adjusted annual rate with September's. Monthly existing-sales changes are near coin-flips; elevated rates and constrained affordability give a modest downward tilt. A sharp fall in mortgage rates or a September-to-October rebound in contract signings would materially lower the odds.

Answer

Grok (xAI): 53% — October SAAR print vs September, released ~Nov 20. NAR posts seasonally-adjusted existing-home sales around the 20th; only that MoM sign matters. Base rate of MoM declines in the SA series is ~52% over the last decade of rate-driven volatility. A surprise September rebound or a 50-bp rate drop before mid-month would flip the call.

Answer

DeepSeek (DeepSeek): 54% — It hinges on whether October's pending sales softness outweighs September's 1.5% gain, with rates near 6.3%. NAR releases October existing home sales around Nov 19-20; the print reflects closings on contracts signed mostly in August-September. September sales rose 1.5% to a 4.06M pace, so October needs a genuine pullback; mortgage rates hovering near 6.3% have kept buyer traffic weak. Pending home sales fell in August and were flat in September, a mild negative lead; the base rate for month-over-month declines in this rate environment is roughly a…

Answer

Qwen (Alibaba): 57% — High-rate lock-in effect keeps inventory thin, tilting the base rate of monthly declines above even odds. NAR's October data release (~Nov 20) is the relevant report; seasonally adjusted MoM declines occur ~50% of months in neutral conditions. With mortgage rates still elevated, the lock-in effect suppresses new listings, capping sales volume and pushing decline probability to ~55-60%. A surprise drop in rates or a policy shift (e.g., FHA/VA easing) would be the main catalyst to flip this toward an increase.
