Parcl and Polymarket have entered a partnership to bring housing data into prediction trading. The collaboration focuses on using daily price indices rather than property-level data. It adds a new angle to real estate prediction markets in the US.

• Polymarket will launch housing-focused markets that settle against Parcl’s published daily indices. Traders can take positions on whether home prices in selected cities rise or fall over set periods. Settlement is based on clearly defined, publicly available index values.

• Parcl will provide the independent index data and act as the reference point for market resolution. Each market will link to a dedicated Parcl resolution page showing final values and methodology. This is designed to allow public verification of outcomes.

• The first markets will focus on major US metropolitan areas with higher liquidity. Market questions will cover monthly, quarterly, and yearly index movements, as well as threshold-based outcomes. Additional cities and formats will be added over time.

• The partnership also includes plans for future product collaboration. Parcl is exploring the integration of Polymarket’s implied probabilities into its analytics platform. This would add an extra forecasting signal alongside existing housing data.
