KuCoin vs Lighter

Ranked only with 24 hours of funding history (288 samples) and a stddev above zero: a young listing, or a venue whose rate has not moved since listing (Ondo Perps at launch, Polymarket in July), reads artificially stable and shows as Provisional, never as the leader. Stability is not directionality: a persistently positive but tight band ranks above a rate that flips every settlement.

Every row is a month of funding at the venue's average daily cost over the hours measured in the trailing 30 days (average x 30). A venue ranks only with 576 of the 720 hours (24 days) behind that average; under the floor the row is provisional, unranked, and shows its day count (the venues added on 2026-09-22 and 2026-09-23 start there). Funding is signed: on a month where shorts paid longs the figure is negative and "cheapest" means "was paid the most".
