Because multiple eligible Kalshi contracts could cross the provisional Polymarket fifth and the published rule requires venue-displayed per-contract USD volume, the cross-venue top five was not proven. No probabilities, entries, scores or substitute contracts were filed from this capture. Archived API responses remain in the Federation private evidence store and are not included here."
