The Iowa Electronic Markets (IEM) are operated by the University of Iowa's Tippie College of Business as academic research and teaching tools. Established in 1988, the IEM is one of the oldest electronic prediction markets in the world with a well-documented track record of political election forecasting.
The IEM operates under a no-action letter from the CFTC, with trading limited to small stakes ($500 maximum investment). The markets have been particularly notable for their accurate presidential election forecasts, often outperforming polls.
Editor's Verdict
The Iowa Electronic Markets are the academic gold standard for election prediction — 35 years of research data and a verified track record of outperforming polls on presidential outcomes.
