Polymarket launches 15-minute gold, silver prediction markets with Chainlink

Extending sub-hourly up-or-down markets from crypto into gold and silver is a meaningful test of whether short-cycle prediction contracts can find demand in traditional macro assets, where intraday moves are typically smaller and driven by different flows. The choice of Chainlink as oracle partner puts settlement infrastructure front and center: at this cadence, any latency or dispute in price feeds becomes a product risk rather than a back-office detail. The stated plan to add stocks and forex signals Polymarket is positioning itself as a general short-term event venue, not a crypto-native one. Worth watching is whether these commodity contracts attract liquidity comparable to crypto markets, and whether oracle reliability holds as frequency rises.
