Entered already? You can add stake to the same prediction — or cancel for a full refund — until lock.

Predict where this event's index price will be, with any stake from $0.10 up to $1,000,000, while the round is open. One prediction per round — you can add stake to it, but the level is locked in.

At the boundary the round locks. No entries, top-ups, or cancellations after lock. Until lock you can cancel for a full refund.

When the measurement window ends, the settlement index P1 decides it: the prediction(s) closest to P1 win. Winners get their stake back plus the losers' pool, split in proportion to stake.

Fewer than two players, everyone tied, or an index outage voids the round and every entry is refunded in full. Each round is pinned to the headline shown above when the round opens.

Zero fees — winners take the entire losing pool, and a winner never gets back less than their stake.
