How the funding rate is calculated
Each venue computes a premium: the difference between the perpetual's mark price and the spot index, averaged over the interval. A fixed interest component, usually 0.01% per eight hours, is added, and the result is clamped to a maximum. Hyperliquid settles every hour, Lighter and RISEx hourly, while Binance, Bybit, OKX, and BloFin settle every four or eight hours depending on the market.
The payment is rate multiplied by position notional. A 0.01% rate on a $100,000 position is $10 per interval, regardless of how much margin backs the position. That is why funding matters more the higher your leverage: at 20x, a $10 payment is 0.2% of your margin every interval.
Reading and comparing funding
Persistently positive funding means the market is paying to be long: traders are crowded on that side and willing to pay for it. Extreme readings, positive or negative, often precede sharp reversals because the crowded side is the one that gets liquidated when price turns. Funding near zero means the perp is trading close to spot.
Because intervals differ, raw rates are not comparable across venues. Proliquid's funding pages normalize every rate to an 8-hour equivalent and an annualized figure. Annualized funding is an extrapolation of the current rate, not a promised yield; rates change every interval. When two venues disagree on the same market, a long on the cheaper venue and a short on the dearer one collects the difference: that is funding arbitrage, before fees, slippage, and the margin required on both sides.
Example: what a BTC long pays over a day
WORKED EXAMPLEA trader holds a $50,000 BTC long on Hyperliquid at 10x leverage, so $5,000 of margin. Hourly funding is running at +0.0012%.
- Rate per hour
- +0.0012% (longs pay)
- 8-hour equivalent
- +0.0096%
- Annualized
- About +10.5%
- Payment per hour
- $0.60
- Payment per day
- $14.40, or 0.29% of margin
- Same size on a venue at -0.0050% / 8h
- Receives $7.50 per day
Over a month the Hyperliquid long pays about $432 in funding, 8.6% of its margin. A short on the negative-funding venue against it would have collected the spread instead.
