SneakerPing predictions blend an XGBoost ensemble model trained on 365 days of pricing history with a 10-factor heuristic (liquidity, hype score, retail premium, volatility, brand momentum). Each shoe is rescored about once a week. The 7-day and 30-day forecasts have been checked against the actual market on tens of thousands of past target dates; the 90-day, 6-month and 1-year horizons are extrapolations that have not produced a graded result yet, because the first ones do not come due until September 2026, December 2026 and June 2027 respectively. Published accuracy stats cover the checked horizons, on our accuracy page. Confidence scores below 60% indicate sparse historical data; treat those forecasts as directional rather than precise.
