From the whale trades we capture ($1,000+) on this market, Oct 25, 2026. Whether it resolved, and each whale's record, are from the daily run. “Made on it” is what each whale took out plus what its shares paid at the end ($1 for the winner, nothing for the rest), counting only trades we captured. A dash means it sold more than we saw it buy, so part of its position is missing and it's left out of the totals. How profit is counted.
