Final take
Should you choose ForecastEx or Polymarket?
For US-based traders, ForecastEx is the obvious starting point: Polymarket is not legally available in the United States. ForecastEx is the best option for serious traders who already use Interactive Brokers, who want regulated US exposure, and who prefer a brokerage workflow over a consumer app.
