20% — the median of 6 frontier models, resolving by 2029-10-31.

Answer

Gemini (Google): 22% — A nominal 10% national drop requires forced selling or sharp unemployment spikes that chronic supply shortages strongly buffer. Nominal Case-Shiller drops of 10%+ have occurred only during the 2007-2011 crash; minor dips like 2022 reversed at roughly 3%. Mortgage rate lock-in and structural deficits of 2-4M units keep inventory tight enough to prevent broad national nominal panic. A deep recession raising unemployment above 6.5% before 2028 would overwhelm inventory limits and push odds above 50%.

Answer

Claude (Anthropic): 32% — Hinges on mortgage rate path, inventory build, and whether a labor-market downturn forces distressed selling before 2029. National Case-Shiller index has never fallen 10%+ outside 2007-12 bust; last few years saw only mild regional softening despite 7%+ rates. Affordability remains historically stretched and inventory is rising in Sun Belt/Texas/Florida, raising odds of a meaningful correction if rates stay elevated or… A Fed-driven rate drop reviving demand, or continued wage growth outpacing prices, would most likely keep this from resolving yes.

Answer

GPT (OpenAI): 63% — It turns chiefly on whether affordability stress or recession produces enough forced selling to overcome tight housing supply. National nominal home-price drops of 10% are uncommon, but 2007–12 shows they occur when credit and labor markets deteriorate together. By end-2028, the Fed, labor market and mortgage rates must weaken demand before builders and locked-in owners restore supply-demand balance. A sharp rise in unemployment or mortgage delinquencies would raise the odds; sustained rate cuts without recession would materially lower them.

Answer

Grok (xAI): 18% — A 10% national peak-to-trough drop needs a sharp recession plus credit freeze inside ~26 months. Only the GFC produced a national Case-Shiller 10%+ decline in 50 years; 2022 was ~5%. Inventory remains structurally tight and rates are more likely easing than spiking by 2028. An unemployment jump past 6.5% plus mortgage-credit contraction by mid-2027 would reverse this.

Answer

DeepSeek (DeepSeek): 12% — A 10% national home price drop needs a recession-scale shock within 24 months, and none is currently forecast. Case-Shiller national index has never fallen 10% peak-to-trough outside 2006-2012, so the base rate over any 2-year window is roughly 5-10%. Prices are currently rising ~2-4% annually with inventory near historic lows, so a 10% drop requires a sharp reversal within ~24 months. The trigger would be a Fed hike cycle or unemployment spike above 5%, neither of which is forecast by consensus before 2028.

Answer

Qwen (Alibaba): 13% — Requires a recession severe enough to break the lock-in supply constraint that has kept prices elevated despite high rates. National 10%+ Case-Shiller declines have occurred essentially once since WWII (2006-2012), giving a base rate of ~2-3% per year. The mortgage lock-in effect and post-2008 lending standards create a supply floor that 2006 lacked; unemployment would need to spike well above 6% to force enough… A severe recession or financial crisis by mid-2028 would be the main catalyst that moves this above 25%.
