Polymarket has launched 15-minute up/down prediction markets for gold and silver, expanding its high-speed trading format beyond cryptocurrencies into other asset classes. The new markets are powered by Chainlink, which serves as Polymarket's official oracle partner for these short-duration contracts. The platform plans to add more commodities in the near term, with expansion into equities and forex markets to follow. Both Polymarket and Chainlink confirmed the launch on X, underscoring the deepening partnership between the two projects.
