History

Historical Context

The Iowa Electronic Markets, launched during the 1988 presidential race, first proved that electronic prediction markets could out-perform polls, correctly signaling George W. Bush’s win in 2000 with a 70 % probability. Maine’s 2018 adoption of ranked-choice voting gave analysts new data points, and after Kalshi’s October 2024 court victory, modern platforms such as Polymarket now assign an 86-89 % chance to Hannah Pingree in the 2026 race.
