Rnz: Afternoons With Jesse Mulligan

Celebrity weddings, the war in Ukraine, election outcomes; the future is now a marketplace with the rise of prediction apps like Polymarket and Kalshi. Users can put money on trades about what might happen in politics, pop culture and sports. Bobby Allyn is a technology correspondent for National Public Radio who met two traders making $100,000 a month on these sites. Supporters say the wisdom of crowds is more accurate than polls. But there are fears prediction markets are ripe for misinformation and manipulation. Allyn explains how they work, who is making money and what is being done to manage what some see as nothing more than high-tech gambling.
