For the 2024 presidential race, Miller is once again relying on PredictIt. He praises the site for “having a more stable group of investors” than the populations screened by pollsters. “You have tens of thousands of people betting on the site at all times of the day,” he says. “The maximum contract is $850, and 37,000 ‘shares’ are traded on average every day.” Put simply, Miller regards PredictIt as a highly liquid market resembling an exchange for, say small-cap stocks or high yield bonds that gathers huge numbers of buyers and sellers. “Financial markets are forward-looking, and incorporate information instantaneously, and PredictIt provides the same benefits,” says Miller.
Is Harris ahead of Trump? This model says yes
For gauging Biden-Trump rematch, Miller developed a “generalized, linear model” based on results from the most recent sixteen presidential elections starting in 1960. Starting with that year’s Kennedy-Nixon race, every presidential race has been decided by 538 electoral votes. “The model’s based on a lot of historical data,” says Miller. It shows that the daily pricing on PredicitIt translates closely into the share of the popular vote favoring each candidate. Say on a certain day, bettors give candidate A a quote of 52 cents, amounting to 52% chance of winning. By Miller’s reckoning, those 52% odds should also mean that at that moment, the best forecast holds that 52% of likely voters plan to cast their ballots for candidate A.

Did your average investor really think that Kamala is gonna win?
