 This week we talk about prediction markets, incentives, and gambling addiction.We also discuss insider trading, spot-fixing, and Gatorade.Recommended Book: The Kingdom, the Power, and the Glory by Tim AlbertaTranscriptPrediction markets are hundreds of years old, and have historically been used to determine the likelihood of something happening.In 1503, for instance, there was a market to determine who would become the next pope, and from the earliest days of commercial markets, there were associated prediction markets that were used to gauge how folks thought a given business would do during an upcoming economic quarter.The theory here is that while you can just ask people how well they think a political candidate will fare in an election or who they think will become the next pope, often their guesses, their assumptions, or their analysis will be swayed by things like political affiliation or maybe even what they think they’re meant to say—the popular papal candidate, for instance, or the non-obvious, asymmetric position on a big commercial enterprise that might help an analyst reinforce their brand as a contrarian.If you introduce money into the equation, though, forcing people to put down real currency on their suspicions and predictions, and give them the chance to earn money if they get things right, that will sometimes nudge these markets away from those other incentives, making the markets commercial enterprises of their own. It can shift the bias away from posturing and toward monetization, and that in turn, in theory at least, should make prediction markets more accurate because people will try to align themselves with the actual, real-deal outcome, rather than the popular—with their social tribe, at least—or compellingly unpopular view.This is the theory that underpins entities like Polymarket, Kalshi, Manifold Markets, and many other online prediction markets that have arisen over the past handful of years as regulations on these types of businesses have been eased, and as they’ve begun to establish themselves as credible players in the predicting-everything space.In politics in particular, these markets have semi-regularly shown themselves to be better gauges of who will actually win elections than conventional polls and surveys, and though their records are far from perfect and still heavily biased in some cases, such community-driven predictions from money-motivated markets are gaining credibility because of their capacity to incentivize people to put their money where their mouths are, and to try to profit from accurate preordination.The flip-side of these markets, and some might even say a built-in flaw with no obvious solution, is that they are rife with insider trading: people who are in the position to know things ahead of time making in some cases millions of dollars by placing big bets that, for them, aren’t bets at all, because they know what will or what is likely to happen.This seems to have occurred at least a few times with big political events in 2025, and it’s anticipated that it could become an even bigger issue in the future, especially for markets that use cryptocurrencies to manage payments, as those are even less likely than their fiat currency peers to keeps solid tabs on who’s actually behind these bets, and thus who might be trading on knowledge that they’re not supposed to be trading on.That said, it could be argued that such insider trading makes these markets even more accurate, eventually at least. And that points us toward another problem: the possibility that someone on the inside might look at a market and realize they can make a killing if they use their position, their power to sway these markets after placing a bet, giving them the ability to assure a payout by abusing their position—major events being influenced by the possibility of a community-funded payday for those in control.What I’d like to talk about today is the same general principle as it’s playing out in the sports world, and why the huge sums of money that are now sloshing around in the sports betting industry in the US are beginning to worry basically everyone, except the sports betting companies themselves.—In October of 2025, the head coach of the NBA basketball team, the Portland Trail Blazers, Chauncey Billups, Miami Heat player Terry Rozier, and former NBA player Damon Jones, and about 30 other people were arrested by the FBI due to their alleged illegal sports gambling activities. Rozier was already under investigation following unusual betting activity that was linked to his performance in a 2023 game—he was later cleared of wrongdoing, but the implication then and in this more recent instance is that he and those other folks who were rounded up by the FBI may have been involved in rigging things so they could get a big payoff on gambling markets.Similar things have been happening across the sports world, including a lifetime ban for Jontay Porter, a former ...
