Resolution criteria on PolyGram: This market will resolve according to the median home value for all property types in the Washington, D.C. Metro area on June 30, 2026. If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket. The resolution source will be official data from the Parcl Labs Sales Price Index for the Washington, D.C. Metro area (Parcl_ID: 2900475). The settlement price will be calculated by multiplying the published price index value (price per square foot) by 1800 square feet, which is the median home size in the Washington, D.C. Metro area. Parcl is set to publish this data on June 30, 2026.

The Washington, D.C. Metro median home value will be calculated on 30 June 2026 using Parcl Labs' Sales Price Index methodology: the published price per square foot multiplied by 1800 square feet, the area's median home size. The current order book on Polymarket implies a 27% probability that the median will fall within a specific bracket, reflecting trader positioning ahead of the settlement window's closure in mid-2026.
The D.C. Metro housing market has experienced significant volatility over the past five years, with median values fluctuating between approximately $550,000 and $650,000 depending on market conditions and measurement methodology. Historical precedent suggests that Federal Reserve policy shifts, mortgage rate movements, and regional employment trends in the federal government and technology sectors have been primary drivers of valuation changes. The current implied probability of 27% suggests traders are pricing in either a relatively narrow band outcome or positioning against consensus expectations formed earlier in the market's lifecycle.
Key catalysts through June 2026 include quarterly Federal Reserve policy decisions, which directly influence mortgage rates and buyer affordability across the region. Employment data from the federal government and Northern Virginia's tech corridor will signal demand strength. Additionally, any significant policy changes affecting remote work arrangements or federal workforce composition could reshape migration patterns into the metro area. Recent housing data releases and mortgage rate trajectories will provide concrete signals for position adjustments as the settlement date approaches.
