74% — the median of 6 frontier models, resolving by 2029-10-31.

Answer

Gemini (Google): 74% — Persistent supply deficits and steady nominal wage growth make nominal annual price gains the overwhelming historic default. Nominal existing-home median prices have risen YoY in over 80% of years since 1970, falling primarily during severe housing busts. Mortgage rate easing from 2024-2025 peaks unlocks marginal buyer demand faster than new inventory can catch up by 2027. A deep US recession driving double-digit national unemployment by late 2026 is the primary scenario that would force broad price cuts.

Answer

Claude (Anthropic): 75% — Hinges on whether mortgage rates ease enough to sustain modest price growth without a demand shock or recession. US median home prices have risen YoY in all but a handful of years since 1990s, including through most rate-hike cycles. Housing supply remains structurally tight in many metros, supporting nominal price floors even amid affordability strain. A recession or sharp rate spike causing forced selling and inventory surge would be the main scenario that flips this negative.

Answer

GPT (OpenAI): 71% — The result mainly turns on whether mortgage rates ease enough to revive demand faster than listings grow. NAR’s annual median existing-home price has risen in most calendar years since 1990, including through several weak-sales periods. The Fed, bond market, and lenders must deliver materially lower borrowing costs during 2027; affordability is the key near-term constraint. A sharp recession with forced selling or a sustained inventory surge would most likely flip the outcome negative.

Answer

Grok (xAI): 78% — Whether 2027 avoids a recession-driven housing correction after 2026 levels. NAR annual median existing-home price must simply exceed the 2026 figure once full-year 2027 data are in. Nominal US existing-home medians rose in ~35 of the last 40 years; only deep recessions produce annual drops. A 2027 recession pushing unemployment above 7% would be the clearest reversal.

Answer

DeepSeek (DeepSeek): 58% — It hinges on whether mortgage rates fall enough in 2027 to thaw a frozen, low-inventory market. NAR's median existing-home price has risen YoY in roughly 13 of the last 15 years, so the base rate is high. The Fed's 2026 cuts have pushed the 30-year toward 6%, and further easing into 2027 would lift buyer demand against still-tight supply. A recession that spikes unemployment and forces distressed selling is the main scenario that would flip this to a decline.

Answer

Qwen (Alibaba): 74% — Persistent inventory shortage from rate lock-in keeps supply constrained enough to outpace any demand softening. Since 1999, median existing-home prices rose YoY in roughly 20 of 27 years (~74% base rate), and the current supply drought is structural, not cyclical. Homeowners holding sub-5% mortgages continue to suppress listings; even a mild 2027 slowdown is unlikely to generate the forced-selling volume needed to break prices. A sharp recession with unemployment above 6% and a surge in distressed inventory would be the main scenario to flip this, but that remains a tail risk rather than the…
