Each prediction stakes 1–100 points, deducted immediately — a wrong guess loses the stake
Correct binary, head-to-head, multiple-choice, or weight-band prediction: stake × that market's number of outcomes (e.g. 2x on a 2-outcome market, 25x on a 25-outcome one)
Numeric-closest guess: everyone's stake pools together and the closest guess(es) split the pool proportional to their own stake; ties split it between just the tied winners
Early prediction bonus: +5 flat points for correct predictions made in the first 25% of a market's open window
No score changes after a market closes — resolution locks in the outcome
