“Say a few words about why you’re making this forecast…”
With every forecast you make, you create training data for SCORE’s AI. Remember to make a comment on your trades!
Trading is open for two weeks, after which the markets are frozen until the final result is known. From each round, only about 10 markets will resolve and pay out. DARPA will begin to reveal those resolved markets in mid-2020. For more details, read Explanation of Payouts.
To compete for more immediate payouts, make sure to participate in Survey weeks! Round 5 Surveys open January 6, 2020.
