The article argues that political prediction markets can offer a useful, though imperfect, indication of the 2028 US presidential race by making participants financially accountable for their forecasts. It says these markets may reveal distinctions that opinion polls and partisan commentary miss, such as the difference between a candidate’s chances in a party primary and in a general election.

At the time cited, Marco Rubio had a 17% market-implied chance of becoming president, narrowly ahead of JD Vance on 16%, while Gavin Newsom and Jon Ossoff were each on 11%. The Democratic nomination market had traded $153.4 million in volume, with Newsom at 20%, Alexandria Ocasio-Cortez at 16% and Ossoff at 15%; on the Republican side, Vance led nomination odds at 40% to Rubio’s 29%. The author notes concerns around regulation and manipulation, but says increased market liquidity has strengthened their value as a source of probabilistic information.
