The death of the pope is a world event. As the spiritual leader of over a billion Catholics, the pope holds a unique position of both moral authority and diplomatic influence. The death of Pope Francis on April 20, is notable for even more reasons. He was a beloved figure who emphasized humility, justice, and interfaith dialogue in a church that now has a larger presence in the global south than in the global north.
The new pope will be elected through a papal conclave in which over 100 cardinals (who are senior members of the Catholic clergy) will meet together in closed-door deliberations inside the Vatican. It is dramatic viewing as the crowd outside waits for smoke to float out through a chimney indicating that a round of voting has finished. Black smoke indicates that no individual has enough votes to be elected, but white smoke means that the new pope has been chosen.
Papal conclaves capture our imagination because of the potential for drama and internal politics (see the recent Conclave movie for example). Yet, despite the secretive nature of what happens inside the papal conclave, people outside of the conclave have their opinions about who will be the next pope.
In fact, it is even possible to place a bet on who will be the new pope! See this Newsweek article.
To economists, a betting market is a method for aggregating information about uncertain future events. Unlike an opinion poll or an expert's forecast, a betting market incentivizes participants to put their money where their mouth is. This creates an incentive to act on genuine beliefs rather than wishful thinking. When many individuals place bets based on their own knowledge or research, the market odds reflect a collective estimate of the probability of an outcome. In fact, betting markets have been shown to outperform polls in predicting election results, sports outcomes, and even policy decisions.
So, what do the betting markets say? According to one betting venue, the betting favorite is Pietro Parolin, an Italian who has been serving as the Vatican's secretary of state since 2013, while the second favorite is Cardinal Luis Antonio Tagle from the Philippines. According to a different betting venue, Tagle is the favorite. Information is still being aggregated, and it is not clear where the betting lines will be when the conclave begins on May 6.
But be careful. A betting market's ability to predict is only as good as the information and beliefs of the people who place bets. If bettors are primarily betting for entertainment purposes and lack credible information, then the betting odds will not be accurate. For example, bettors might enjoy picking long shots, as if they are trying to win a lottery rather than betting their genuine beliefs. So, betting markets are not perfect aggregators of information, just like surveys and expert predictions are not perfect.
But what if you really want to place a bet? Online gambling is illegal in California, and sports books in Nevada are not taking bets on the new pope. So, if you want to place a bet, you'll have to do it in another country. Many countries in Europe, for example, allow betting on the new pope.
