Methodology: one official Bubba estimate per market is captured shortly after listing. Each entry is graded once the Kalshi market settles. Hit rate measures directional correctness (did Bubba's gap point the right way). Brier score measures probability calibration (mean of (estimate − outcome)²; lower is better).
