Funding Rate (US100)

The US100 funding rate is a periodic payment between long and short traders on perpetual futures, designed to keep the contract price anchored to the spot index. When the rate is positive, longs pay shorts; when negative, shorts pay longs. It is the main ongoing cost (or income) of holding a leveraged US100 perpetual position.

A persistently positive US100 funding rate signals crowded long positioning and bullish sentiment — longs keep paying to stay in the trade. A negative rate signals short-side dominance and bearish sentiment. Extreme funding rates in either direction often indicate an overcrowded trade and raise the risk of a sharp reversal or short squeeze/long squeeze.
