Polymarket has launched a new prediction market—will there be a meteor shower of impact level this year? These probability-based trading markets are becoming an interesting testing ground for Web3 applications. Users can express their judgments on various events by trading prediction contracts, thereby discovering the market's pricing efficiency for real events. Whether it's climate, space, or geopolitical events, prediction markets are driving the price discovery mechanism of information. This also reflects how decentralized applications find their place in real-world scenarios.
