Perpetual futures never expire, which raises a question: what keeps the perp price glued to the real price of the asset? The answer is the funding rate, a small periodic payment between traders. If you hold positions for more than a few hours, funding directly affects your bottom line, so it is worth five minutes to understand.
The problem funding solves
A traditional futures contract has an expiry date, and at expiry it settles to the real price. That settlement anchors the contract's price to reality. A perpetual contract never settles, so without a substitute mechanism, its price could drift far from the actual market.
Funding is that substitute. It uses a simple incentive: make the crowded side of the market pay the uncrowded side.
Who pays whom
- When the perp trades above the underlying price, meaning longs are dominant, the funding rate is positive and longs pay shorts. Holding a long costs money, holding a short earns money, and the pressure nudges the perp price back down.
- When the perp trades below the underlying price, the rate is negative and shorts pay longs, nudging the price back up.
The payment flows directly between traders. The exchange does not take it.
How often and how much
On Hyperliquid, which powers Hyperbeat Trade, funding changes hands every hour. Hyperliquid computes the rate as an 8 hour figure and charges one eighth of it each hour, so a position pays or receives a small amount for every hour it stays open. The countdown next to the market name ticks down to the next hourly payment.
The amounts are small per hour. Say the current rate is 0.001 percent per hour. On a 10,000 USDC position that is about 0.10 USDC each hour, or roughly 2.40 USDC a day. That sounds trivial, but two things can make it bite:
- Leverage. Funding is charged on your full position value, not your margin. On a 20x position, funding relative to your actual margin is 20 times larger.
- Time. During strong trends, funding can run high for weeks. Annualized, a persistently elevated rate can exceed 30 or even 100 percent against the crowded side.
Under the hood: how Hyperliquid sets the rate
The funding rate is built from two parts: an interest component and a premium.
- Interest is a fixed 0.01 percent per 8 hours (0.00125 percent per hour), the baseline longs pay shorts when the market is balanced.
- Premium reflects how far the perp is trading from the oracle price of the underlying, using the order book's impact prices.
The full rate is premium + clamp(interest − premium, ±0.05%), and Hyperliquid caps funding at 4 percent per hour so it can never run away in a violent market. Each hour, your payment is position size × oracle price × funding rate, so it is measured against the position's full notional value, not your margin. You never compute this yourself, but it explains why the number moves the way it does.
Where to see funding on Hyperbeat Trade
- The stats strip next to the market name shows the current funding rate and a live countdown to the next hourly payment. Hover over it for an annualized figure.
- The market selector has an 8H Funding column for every market, sortable, which is handy for comparing markets and spotting extremes.
- The Positions tab has a Funding column showing the cumulative funding your position has paid or received since it opened.
- The Funding History tab records every individual payment, and you can export it as CSV.
What funding means for your trading
- Short-term traders can mostly ignore it. If you are in and out within minutes or hours, funding is a rounding error next to spreads and fees.
- Position holders must budget for it. If you plan to hold a long for a month while funding is strongly positive, you are paying rent the whole way. Factor it into your target.
- Funding is a sentiment gauge. Extremely positive funding means the market is heavily long, which often accompanies overheated moves. Extreme readings in either direction are worth noticing, though they are not a timing signal by themselves.
- Getting paid to hold. If your position happens to be on the uncrowded side, funding works for you. Some traders build entire strategies around collecting funding while hedged, but that is an advanced topic with its own risks.
The one-line summary
Funding is the perp market's balancing mechanism: the crowded side pays the uncrowded side, hourly, until prices realign. Check the rate before you open a position you intend to hold, and glance at your cumulative funding in the Positions tab while it is open.
