Polymarket's real estate prediction market feature is now live. This means users can now trade and hedge on housing price trends through on-chain prediction markets, effectively combining traditional real estate investment with the liquidity of crypto markets. Such applications expand the boundaries of prediction markets—from political elections and sports events to physical asset price discovery—demonstrating how Web3 infrastructure is gradually integrating into mainstream finance. As one of the largest asset classes, real estate could benefit from decentralized methods that provide more transparent price signals and risk hedging tools, which are practically meaningful for market participants and asset valuation.
