Throughline

Throughline appears in Before Kalshi and Polymarket there was the Iowa Electronic Markets as the NPR history podcast whose reporting is excerpted in the Planet Money feed. In this source, Throughline provides the historical arc behind prediction markets rather than a narrow current-events segment.

The episode’s Throughline material connects modern platforms such as Kalshi and Polymarket to the Iowa Electronic Markets and older Election Betting Markets. Its wiki role is to supply historical depth for a topic the existing prediction-market branch had mostly treated through current regulation and ethics.
