Hyperliquid Funding Rates Explained: Hourly Formula, Caps, Oracle vs Mark Price, Open Interest and Volume (2026)

Hyperliquid funding rates are paid every hour between longs and shorts to keep each perpetual's price pinned to its oracle price; the rate is computed from the perp's hourly average premium plus a 0.01% per-8-hour base rate, paid at one eighth of the 8-hour figure each hour, and capped at 4% per hour. Positive funding means longs pay shorts, negative means shorts pay longs. This guide explains the formula, the oracle-versus-mark distinction, how to read Hyperliquid open interest and volume, where to find the data (app, Coinglass, Hyperdash, DefiLlama, API), typical funding regimes and the basics of funding arbitrage.

Key takeaways

• Funding is hourly on Hyperliquid, not every 8 hours as on most CEXs; rates are quoted as 8-hour equivalents and paid at 1/8 each hour.
• Formula: premium relative to the oracle price plus a clamped interest component around a 0.01% per 8h base rate; hourly payments are capped at 4%.
• Oracle price (CEX spot median) drives funding; mark price (oracle + book + external perps) drives liquidations and P&L.
• Open interest is the total notional of open positions; rising OI with rising price signals new longs, rising OI with falling price signals new shorts.
• Hyperliquid daily volume is $5–15 billion as of September 2026, the largest on-chain; OI typically $8–15 billion.
• Funding is a transfer between traders; the protocol keeps none of it.

Hyperliquid funding rates: why perps need funding

A perpetual future has no expiry, so nothing forces its price to converge with the underlying. Funding is the fix. When the perp trades above the oracle price, longs pay shorts, making it costly to stay long and attractive to short until the gap closes; when the perp trades below, shorts pay longs. Hyperliquid runs this mechanism for every perp on the platform, from BTC and HYPE to HIP-3 markets like XYZ100, NVDA and WTI crude.

Two design choices set Hyperliquid apart. First, funding settles every hour, which keeps the perp much closer to its index than 8-hour cycles do and reduces the "funding sniping" seen on exchanges where traders open positions seconds before settlement. Second, funding is computed from on-chain data (the order book's impact price versus a validator-provided oracle), so anyone can verify it.

The Hyperliquid funding formula

Hyperliquid follows the same premium-and-interest structure as major exchanges, adapted to hourly payment.

Step 1: Premium. Every few seconds the engine samples the impact bid and impact ask prices (the average execution price for a fixed notional, so a few tiny orders cannot skew it) and computes:

premium = (max(impact bid − oracle, 0) − max(oracle − impact ask, 0)) / oracle

Over the hour these samples are averaged into the average premium index.

Step 2: Interest component. A fixed interest rate of 0.01% per 8 hours represents the cost of holding the quote asset versus the base asset. The difference between the interest rate and the premium is clamped to ±0.05%.

Step 3: 8-hour funding rate.

funding_8h = average premium + clamp(0.01% − average premium, −0.05%, +0.05%)

Step 4: Hourly payment.

hourly payment = (funding_8h / 8) × position size × oracle price

capped so that no single hour exceeds 4% of notional in either direction.

Worked example: BTC trades at an average 0.04% premium to its oracle during the hour. funding_8h = 0.04% + clamp(0.01% − 0.04%) = 0.04% − 0.03% = 0.01%. Hourly rate = 0.01% / 8 = 0.00125%. A $100,000 long pays $1.25 for that hour. If the premium spikes to 0.5%, the clamp binds at −0.05%, funding_8h = 0.45%, hourly = 0.05625%, and the same long pays $56.25 per hour, roughly $1,350 a day.

Notice that when the market is perfectly balanced (premium = 0), funding settles at the base rate of 0.01% per 8h, or about 0.00125% per hour, paid by longs. Over a year that is roughly 11%, which is why "neutral" funding still slightly favors shorts.

How funding hits your account

Payments are debited or credited to the position's margin at the top of each hour and shown in the Funding tab. On an isolated position, paid funding reduces margin and nudges your liquidation price toward the market; received funding does the opposite. On cross, it flows through account value. See how this interacts with liquidation math in Hyperliquid leverage and liquidation.

Hyperliquid oracle price vs mark price

Two reference prices run side by side, and confusing them causes real losses.

The Hyperliquid oracle is deliberately external: it reflects where the asset trades on the broader market, not on Hyperliquid alone. That is what makes funding meaningful, since the premium measures Hyperliquid's perp against the world's spot price. For HIP-3 markets the deployer supplies the oracle (for example, equity prices from licensed data feeds for NVDA or index calculations for XYZ100), and during off-hours the oracle holds the last close or uses proxy inputs, which is why funding on stock perps can widen sharply on weekends.

The mark price protects you from manipulation. Because it blends the oracle with the book's EMA and external perp prices, a whale slamming the Hyperliquid book cannot liquidate you unless the wider market moves too. Hyperliquid tightened these safeguards after the JELLYJELLY manipulation attempt in March 2025.

Reading Hyperliquid open interest

Open interest (OI) is the total notional value of all open positions on a market, counted once per matched long/short pair. Hyperliquid's platform-wide OI has typically sat between $8 billion and $15 billion as of September 2026, with BTC, ETH, SOL and HYPE accounting for most of it.

How to interpret changes:

Combine OI with funding: rising OI plus sharply positive funding means crowded longs and elevated liquidation cascade risk; rising OI with negative funding means crowded shorts and squeeze potential. The liquidation heatmaps on Coinglass and Hyperdash show where those crowded positions would be forced out.

OI is also capped per market by the protocol: when a perp's open interest reaches its cap, only reduce-only orders are allowed until it falls. Caps are visible in the market info panel and are one of the tools used to keep illiquid perps from becoming systemic.

Hyperliquid volume: daily, 24h and share

Hyperliquid daily volume for perps has commonly ranged from $5 billion to $15 billion in 2025–2026, with single-day peaks above $20 billion during major volatility. Spot volume adds several hundred million to a few billion a day. At its peak Hyperliquid held 70%+ of all on-chain perp volume; competition from Lighter and Aster has pulled that share down at times, but it remains the largest venue by a wide margin (see Hyperliquid vs Lighter and vs Aster).

Why volume matters beyond bragging rights:

• Fees and buybacks. Roughly 0.02–0.03% of volume is collected as net fees, so a $10 billion day yields about $2.5–3 million, nearly all of which the Assistance Fund spends buying HYPE. This is the link between "hyperliquid 24h volume" and the token; see revenue, volume and valuation.
• Liquidity. High volume means tighter spreads and lower slippage for your orders, which usually outweighs fee differences between venues (details in Hyperliquid fees).
• Volume-to-OI ratio. Volume / OI around 1 signals mostly intraday churn; well below 1 indicates positions being held; a spike in volume with flat OI often marks a liquidation flush.

Typical Hyperliquid funding regimes

Funding on Hyperliquid clusters into recognizable regimes. The table uses 8-hour-equivalent rates, which is how the app displays them; divide by 8 for the hourly payment and multiply by roughly 1,095 for a crude annualized figure.

Patterns worth knowing as of September 2026:

• BTC and ETH spend most of their time between 0.005% and 0.03% per 8h. Sustained readings above 0.05% have historically preceded pullbacks.
• HYPE funding runs hotter than majors because holders use the perp to lever up on the token.
• New listings and memes frequently print 0.1%–1% per 8h in their first days, which is where the 4% hourly cap becomes relevant.
• HIP-3 stock perps show funding spikes ahead of earnings and over weekends when the oracle is stale relative to news; commodity perps like gold and oil follow their futures curves more calmly. See stocks and oil market pages.

Funding arbitrage on Hyperliquid

Because funding is a payment from one side to the other, a delta-neutral trader can collect it. The basic cash-and-carry trade:

1. Buy the asset on spot (Hyperliquid spot for HYPE, PURR or Unit-bridged BTC/ETH/SOL, or on any exchange).
2. Short the same notional on the Hyperliquid perp.
3. Collect positive funding every hour while price exposure nets to zero.

The reverse trade (long perp, short spot via borrowing) collects negative funding but is harder to execute without a lending venue such as HyperLend on HyperEVM.

Cross-venue funding arbitrage exploits differences between exchanges: long the perp where funding is lower (or negative) and short where it is higher, harvesting the spread. The predictedFundings endpoint exists precisely for this comparison, and bots on 3commas, Freqtrade and custom builder-code apps automate it.

Costs and risks to model before you try:

• Fees on both legs (0.045% taker or 0.015% maker on the perp, 0.07% / 0.04% on spot), which at elevated funding are recovered within a day or two, but at neutral funding take weeks.
• Funding can flip. A crowded-long market can turn negative within hours after a flush; the trade then pays instead of earning.
• Liquidation risk on the perp leg. Hold modest leverage (2x–3x) and keep spare margin; a hedged trade still liquidates if the perp leg's margin runs out.
• Basis risk between spot on one venue and the perp on another, plus bridge time and cost if you rebalance.
• ADL. In extreme moves a profitable short can be auto-deleveraged, breaking the hedge.

Risk note: funding arbitrage is not risk-free yield. Returns vary, and the leveraged leg can be liquidated. Nothing here is financial advice.

Funding rates as a trading signal

Even if you never arbitrage, funding tells you about positioning:

• Fade extremes. Rates above 0.1% per 8h with rising OI have repeatedly marked local tops; deeply negative rates with rising OI, local bottoms.
• Confirm trends. A rally on neutral funding is healthier than one on extreme funding, because it is not built on leverage that must unwind.
• Time entries. If you want to be long a crowded market, entering right after a funding flush (when OI drops and rates normalize) is usually cheaper than paying peak funding.
• Track whales. When the largest addresses on the leaderboard flip sides, funding often follows within hours.

Bottom line

Hyperliquid pays funding every hour, computed from the perp's average premium over an externally sourced oracle price plus a 0.01% per-8h base rate, clamped and capped at 4% per hour, with the mark price rather than the oracle governing liquidations. Read funding together with open interest and volume: crowded, high-funding, high-OI markets are where liquidation cascades start, and the data is free in the app, on Coinglass, Hyperdash, DefiLlama and the API. Funding arbitrage can turn the mechanism into income, but only after fees, flips and liquidation risk are accounted for. Master these three numbers and the Hyperliquid app DEX becomes far easier to read.
