AI Summary grounded in real data · zero hallucination
Our model assigns a 39% probability to a Portland Timbers victory, higher than Seattle Sounders FC's 35%. This is primarily driven by Portland's strong 'Attack (goals/game)' (deltaPct 3.9) and 'Home Advantage' (deltaPct 3.7). However, 'Defense (goals against/game)' (deltaPct -3.9) poses a key risk, and the edge against the market is not calculated.
Logistic-regression statistical model — predicts Seattle Sounders FC vs Portland Timbers by accumulating the log-odds contributions of 12 proven structured metrics. Only structured metrics enter the probability; qualitative and folklore factors get a label only. Predictions are sealed with SHA-256 before the game.
