37% — the median of 6 frontier models, resolving by 2029-11-10.

Answer

Gemini (Google): 42% — The outcome hinges on whether rising supply and labor market softness can outweigh chronic structural inventory lock-in. NAR monthly year-over-year median prices dip negative in about 20% of post-1970 years, but 2023 already showed it can happen. Sunbelt inventory surges and prolonged 6%-plus mortgage rates weaken pricing power into 2027 as unemployment ticks higher. A rapid Fed easing cycle pushing mortgage rates under 5.5% would revive buyer competition and abort any sustained price drops.

Answer

Claude (Anthropic): 40% — Hinges on whether elevated mortgage rates and inventory buildup finally break nominal price stickiness by late 2027. Nominal YoY home price declines are historically rare post-2012, with only brief dips in 2022-23 despite rate shocks, so base rate is modest. Inventory has been rising in many markets and affordability remains stretched, giving more room for a YoY dip than in prior cycles. A 2027 recession, continued rate persistence above 6.5%, or a labor market crack would most likely tip this into decline; absent that, sellers hold firm and prices stay…

Answer

GPT (OpenAI): 63% — A sustained affordability squeeze must outweigh tight existing-home supply long enough to force nominal price cuts. NAR’s national median existing-home price has fallen year-over-year before, notably during the 2007–11 housing bust, but it is not routine. Mortgage rates near or above 6% through 2027, rising inventory, and weak labor markets would make a December 2027 decline likely. I would lower this materially if rates fall below 5% in 2027 while listings remain constrained by owners’ locked-in low-rate mortgages.

Answer

Grok (xAI): 28% — NAR median prints a YoY drop only if a 2027 recession or rate spike hits before year-end. NAR existing-home median fell YoY solely in 2006-11 and a few 2023 months; Fed cuts expected 2026-27 support prices. Structurally tight inventory means even weak demand rarely produces national declines outside deep recessions. Unemployment above 5.5% by mid-2027 would most change the odds, matching 2008 precedent.

Answer

DeepSeek (DeepSeek): 34% — It hinges on whether mortgage rates stay near 6%+ long enough to force sellers to capitulate before late 2027. Case-Shiller and NAR median prices have never posted a sustained YoY decline without a recession or a 2008-style credit shock; neither is the base case now. The Fed has begun cutting, and 30-year rates near 6.2% in late 2026 are already pulling buyers back, which historically stabilizes prices within 12-18 months. A renewed inflation spike pushing the 30-year back above 7.5% into 2027, combined with rising unemployment, is the one development that would flip this to likely.

Answer

Qwen (Alibaba): 24% — Lock-in effect keeps inventory too thin for national price declines unless a recession forces distressed selling. National median YoY declines are rare outside severe downturns; even the 2022 rate shock produced only brief, marginal dips in NAR data. The 13-month window carries roughly a 25-30% recession probability, but even the 2001 recession didn't produce national price declines—only 2008-level unemployment… A single month of YoY decline lowers the bar meaningfully, but the lock-in effect (homeowners holding sub-4% mortgages) would need to break via mass layoffs or a credit…
