Civil rights leader Jesse Jackson had just trounced Michael Dukakis<\/a> in the Michigan presidential primary \u2014 despite polls predicting Dukakis would win easily. Professor Robert Forsythe and two of his University of Iowa colleagues, George Neumann and Forrest Nelson, wondered how economics might do a better job than traditional polls.<\/p>\n It doesn\u2019t take a Ph.D. to guess the punchline here. \u201cWell, we would make a market off of it,\u201d Forsythe recalled them concluding. <\/p>\n By the time they finished their meal, the trio had settled on an idea: a marketplace for betting on the outcome of events that could serve as a tool for forecasters. \u201cIt\u2019s amazing after a three-beer lunch what you come up with,\u201d he said.<\/p>\n The economists built a prediction market at the University of Iowa as an academic experiment to test whether their idea that betting markets could provide useful information about future events would even work. It did. The Iowa Electronic Markets<\/a> helped plant the seed for the modern-day prediction market companies that have ballooned into a multibillion-dollar industry<\/a>, offering contracts on everything from the Super Bowl<\/a> to the number of times Elon Musk will post on X in early February. <\/p>\n Forsythe sees Kalshi and Polymarket as direct descendants of his academic experiment, and he has been gratified to see the ideas that he and his colleagues spent decades working on now operating at such a massive scale: Kalshi saw more than $1 billion in trading<\/a> on Super Bowl Sunday alone. \u201cIt\u2019s good to see markets having the kind of success they are \u2014 we really launched something,\u201d Forsythe said, adding that the success of companies running with their idea has also stirred \u201ca bit of jealousy.\u201d<\/p>\n The original market in November 1988 was a modest enterprise. They stuck the server in an empty faculty office that was so small it barely had room for two chairs. <\/p>\n They called it the \u201cIowa Political Stock Market\u201d and recruited university staff members and students to buy and sell contracts on how likely Dukakis was to prevail against Republican George H.W. Bush. At the time, most students didn\u2019t even have personal computers to make trades, so they went to student computer labs \u2014 destinations that became outright crowded on Election Day. <\/p>\n Forsythe remembers waiting anxiously with his collaborators for the returns to come in, watching two separate television sets at Forrest Nelson\u2019s house. \u201cAt one point, we were pretty much dead on,\u201d he said, with one of them exclaiming: \u201cOh God \u2014 it better not change very much.\u201d<\/p>\n They didn\u2019t have to worry: Even with a tiny pool of less than 200 traders, the market was shockingly accurate. Its prices correctly indicated that Bush would get exactly 53.2% of the popular vote. The market\u2019s forecast for Dukakis\u2019 vote share was 45.2% \u2014 just 0.2 percentage points below the actual total of 45.4%.<\/p>\n While many of the early traders were political junkies who followed every campaign development, others were students who got more interested once they had \u201ca few dollars on the line,\u201d giving them a financial incentive to seek out new, relevant information that could affect the future outcome, Forsythe said. <\/p>\n The biggest profit in that first market? $13.54, on a $250 investment.<\/p>\n By the next presidential election, the operation had gone national as the \u201cIowa Electronic Markets\u201d with the blessing of the federal Commodity Futures Trading Commission <\/a>\u2014 but only with the understanding that it would remain an operation that ran for \u201csolely academic and experimental purposes,\u201d with no outside advertising, and individual traders couldn\u2019t invest more than $500. The Iowa prediction markets continued to outperform many leading polls<\/a>, especially during the run-up to an election. <\/p>\n The experiment caused a stir among economists and political scientists and people in finance and business circles. While betting on elections had been around for centuries<\/a> \u2014 including in the U.S. during the late 19th and early 20th centuries \u2014 the idea of turning such a market into a modern financial exchange opened up a universe of possibilities. <\/p>\n The Iowa experiment inspired a host of early efforts<\/a> to create electronic prediction markets in the private sector, and even the Defense Department<\/a>, that went well beyond elections. But most of the new entrants, such as Intrade and Tradesports, have floundered after running afoul of federal regulators and federal laws prohibiting internet and sports gambling.<\/p>\n \u201cThere were a lot of people who knew immediately what it was all about and were excited to have the opportunity to trade on the markets,\u201d said Eric Zitzewitz, an economics professor at Dartmouth who has studied prediction markets for decades. \u201cPart of the reason it was at universities first is because it was illegal everywhere else.\u201d<\/p>\n Forsythe said companies wanting to take their prediction market overseas approached him and colleagues, given the restrictions in the U.S. \u201cIn hindsight it probably would have been a smart thing to do,\u201d he said. George Neumann died in 2015 and Forrest Nelson in 2023.<\/p>\n After Polymarket was founded in 2020 and Kalshi the following year, both companies faced fierce pushback from federal regulators during the Biden administration. But a federal court in September 2024 ruled in the industry\u2019s favor<\/a>. <\/p>\n President Donald Trump\u2019s return to office in January 2025 ushered in a new era of regulators who have opened their arms to commercial prediction markets. It didn\u2019t hurt when the president\u2019s son Donald Trump Jr. became an investor in Polymarket<\/a> and a paid adviser to Kalshi. <\/p>\n Both companies have grown exponentially since then, offering the opportunity to bet on events far beyond the original scope of the academic experiment. This month, for example, Kalshi traders were able to bet not only on the outcome of the Super Bowl, but also which song Bad Bunny would sing first <\/a>during the halftime show and whether the game\u2019s announcers would mention the word \u201cGatorade.\u201d<\/a><\/p>\n \u201cWhile the IEM was quite different from Kalshi in liquidity and scale, it did provide something critical to the history of prediction markets: it helped prove that they are accurate,\u201d Jack Such, a Kalshi spokesman, said in a statement.<\/p>\n Commercial prediction markets have resisted efforts by states to classify and regulate them<\/a> as gambling companies, insisting that they \u2014 like their precursor in Iowa \u2014 should be overseen by federal regulators. But there are no federal rules specifically designed for prediction markets to prevent market manipulation or protect consumers.<\/p>\n That has raised some concerns among longtime prediction market experts and researchers. <\/p>\n \u201cIt\u2019s very easy to get into these markets and spend a lot of money and lose a lot of money, and so it is worrisome,\u201d said Thomas Gruca, a professor of marketing at the University of Iowa and the current director of the Iowa Electronic Markets, which has been in continuous operation since its founding. \u201cThere are only so many people who actually have good information. Then you have a lot of people with opinions and money.\u201d<\/p>\n Forsythe agrees that some guardrails are necessary as for-profit prediction markets have taken off, particularly when it comes to issues like market manipulation. The bigger and more influential a market becomes, the more tempting it could be for certain actors to try to manipulate the prices to inflate the chances of a political candidate, for instance. \u201cYou need some kind of oversight in terms of fair reporting, market manipulation and so forth,\u201d he said. (Kalshi recently detailed its support<\/a> for federal regulation to protect prediction market integrity and trust.)<\/p>\n And though Kalshi and Polymarket made headlines for correctly predicting<\/a> that Trump would comfortably win the 2024 election, some research studies have also shown that prediction markets tend to be less accurate<\/a> on speculative questions for which there is little public information to help traders make forecasts.<\/p>\n Still, Forsythe believes that prediction markets, both old and new, can still offer real value in predicting events with major, real-world consequences. And he always expected the industry to take off once it had access to a broad commercial market. \u201cThe only thing I\u2019m surprised about is it took so long to get there,\u201d he said.<\/p>\n","protected":false},"excerpt":{"rendered":" The billion-dollar prediction markets industry began like a joke: Three economists walked into a bar.
