Daily $125 Prize for Time-Series Prediction

Total Reward: $45,625 per year Start: Sep 22, 2021 | End: Jan 1, 2023 or later Sponsor: Microprediction


Every day $125 is awarded for aggregate prediction accuracy in a randomly chosen sub-category. 

Winner determination

  1. Every day at midnight standings will be polled from one of several sub-categories listed by sponsor on the leaderboard.
  2. Every algorithm with a positive score and an assigned email will have a chance of winning the current prize, proportional to their score raised to an exponent. If the chosen algorithm has no email assigned, the prize will jackpot. 
  3. After midnight, points will be multiplied by a discount factor.
