Resolves YES if Swift Centre has a better Brier score than Polymarket, across their five forecasts. Resolves NO otherwise.

Context: Swift Centre claims that Polymarket is not the ultimate source of truth and that their forecasters can beat Polymarket.

Here were their five forecasts:

1) The Swift Centre forecasters saw a ~4% chance of the United States acquiring Greenland in 2026, distinctly lower than the 12% that was on the relevant Polymarket question.

2) The likelihood of Russia and Ukraine agreeing to an indefinite ceasefire of peace agreement this year was forecasted at 22%, considerably lower than the ~43% odds on Polymarket.

3) The forecasters saw a ~6.5% chance of the US taking control of the Panama Canal in 2026, lower than Polymarket’s odds of ~15%.

4) The likelihood of Iranian Supreme Leader Khamenei being out of power by the end of March 2026 was pegged by the Swift Centre forecasters at 27%, compared with Polymarket’s 26%...

5) ...while the likelihood of the US undertaking military strikes on Iran by the same date was estimated at 68%, notably higher than Polymarket’s ~55%. 

If there's controversy as to the outcomes of the Polymarket markets (Swift Centre disputes the resolution or something), then I will side with Polymarket's interpretation; after all, the Swift Centre are forecasting Polymarket questions, not their own analogues.
