Deep dives

Understanding Prediction Markets

Prediction markets serve as platforms where participants can bet on the outcomes of future events, enabling them to purchase shares that pay out contingent on specific results. For example, one can create a market speculating on the outcome of the 2024 U.S. presidential election by buying shares indicating whether a particular candidate will win. The value of these shares is indicative of the collective beliefs about the event's probability, and interestingly, the sum of the prices of yes and no shares often equals one dollar, reflecting the market's consensus. This structure not only enhances engagement but offers a more accurate measure of public opinion compared to traditional polling.
