The forecasting accuracy of Forecast’s users was also fairly good: “Forecast’s midpoint brier score [...] across all closed Forecasts over the past few months is 0.204, compared to Good Judgement’s published result of 0.227 for prediction markets.”
For what it’s worth , as noted in Nuño’s comment this comparison holds little weight when the questions aren’t the same or on the same time scales; I’d take it as fairly weak evidence from my prior that real-money prediction markets are much more accurate.

Right, definitely, I forgot to add this. I wasn’t trying to say that Forecast is more accurate than real-money prediction markets (or other forecasting platforms for that matter) but rather that Forecasts’ forecasting accuracy is at least clearly above the this-is-silly level.
