What is different about BTC on Hyperliquid
The BTC market on Hyperliquid is the oldest and deepest perp on the exchange, listed on the validator-operated dex rather than on a HIP-3 dex, so it uses the standard fee schedule and none of the deployer rules that stock and commodity markets carry. It trades every hour of every day. What sets it apart is less about hours and more about plumbing: where the price comes from, how funding is computed, how the margin table bends for very large positions and how big a single order may be. Those details decide where a liquidation lands and what a long holding costs, so this section goes through them one by one, with the numbers taken from our verified data and from the Hyperliquid API at build time.
The oracle never looks at Hyperliquid's own BTC spot book
Each validator computes a spot price as a weighted median of Binance (weight 3), OKX (2), Bybit (2), Kraken (1), KuCoin (1), Gate (1), MEXC (1) and Hyperliquid spot (1) and publishes it about every 3 seconds; the clearinghouse then takes the stake-weighted median of every validator's submitted price. For Bitcoin there is an extra rule: for a market like BTC, whose main spot liquidity is outside Hyperliquid, Hyperliquid's own spot price is left out of the oracle. The Hyperliquid weight in that list therefore does nothing for BTC, and the funding rate is measured against centralised exchange spot prices only. The mark price, which drives margin checks, liquidations and stop triggers, is the median of three inputs: the oracle plus a 150-second average of the gap to Hyperliquid's mid, the median of Hyperliquid's best bid, best ask and last trade, and a weighted median of CEX perp mids (Binance (weight 3), OKX (2), Bybit (2), Gate (1) and MEXC (1)). A sharp wick on the Hyperliquid book alone moves only one of those three inputs, which is why a thin moment on one venue rarely liquidates a BTC position by itself. The live table above shows the gap between mark and oracle at build time.
One more detail matters if you compare prices across venues: the oracle is a USDT price while margin and PnL are in USDC, with no USDC/USDT conversion (a quanto contract). So the BTC number on Hyperliquid can differ slightly from a USDC spot quote whenever the two stablecoins are not exactly at par.
Funding: the interest-rate baseline and the premium
Funding is paid every hour at one eighth of an eight-hour rate built from two parts: the average premium of the book over the oracle, sampled every 5 seconds, and a fixed interest component of 0.01% per eight hours. The interest component minus the premium is clamped to ±0.05%, so as long as the premium stays inside that band the hourly rate equals the interest component alone, 0.00125%. That figure is a baseline, not a lower bound: when the premium leaves the band, funding moves away from it in either direction and in some hours turns negative. BTC's premium is measured with an impact size of 20,000 USDC per side, the same as ETH, against 6,000 USDC for other assets. In the seven days before this build, 76% of the hourly BTC payments were exactly 0.00125%; the share moves from week to week and differs between markets.
In the twelve months to September 30, 2026, a BTC long paid a summed funding of 5.953% of its position value. A full year at the baseline would have summed to 10.95%; the actual total was lower, and 19% of the hours were negative (shorts paid longs). The worst rolling week summed to -0.132%. Payments are computed on the oracle price, not the mark, and capped at 4% per hour. The seven-day table on this page shows the recent run; the full mechanics are in our Hyperliquid funding rate guide.
The baseline is positive, so in hours that sit on it, longs pay shorts. A position held for 30 days with every hour at the baseline would pay 0.9% of its notional value. Opening and closing the same position once with taker orders at the entry tier costs 0.09% of notional, so those 30 days of funding equal about 10 such round trips. Both figures are shares of position value, so leverage scales them equally and does not change the comparison. Over a 91-day quarter at the baseline the total would be 2.73%: for a hedge held that long at the baseline, funding rather than the trading fee is the main cost. A short that offsets spot Bitcoin collects the same transfer in those hours and pays when funding turns negative. How a short perp position works on a DEX, including the margin it ties up, is covered in our guide to short selling with perpetuals.
Margin tiers, order caps and what size really costs
BTC has the highest leverage on the validator dex, 40x, but only for the first $150M of position value; the part above that is margined at 20x. Maintenance margin is half of the initial margin at each tier's maximum, which at the top tier means an isolated long opened at full leverage sits about 1.27% from its liquidation price. Over the last 30 complete UTC days, the average daily high-to-low range of BTC was 2.47% and the widest day was 4.07%. Most retail positions never reach the second tier; the number that matters for them is how small the distance is at the top of the slider.
Large positions are also liquidated differently. Above 100,000 USDC of value, only 20% of the position goes to the book as a liquidation order at a time, followed by a 30-second cooldown in which any further liquidation order is for the whole position. There is no liquidation clearance fee, but if the account falls below two-thirds of its maintenance margin before the book can absorb it, the liquidator vault takes the position and the remaining maintenance margin is not returned.
Order limits follow the leverage class. Because BTC allows 25x or more, a single market order may be worth up to $30M and a resting limit order up to 10 times that; the smallest order is $10. Sizes step in units of 0.00001 BTC. Prices may carry 5 significant figures, but a whole-dollar price is always valid, whatever its number of significant figures, so at today's price the tick is $1, about 0.0012% of the price.
Weekends and the round-the-clock book
Unlike stock and index perps on HIP-3 dexs, BTC has no internal weekend oracle and no discovery bounds: the same external spot prices feed it on Saturday as on Tuesday. CME's Bitcoin futures trade 24/7 except Saturday 2:00–4:00 a.m. CT and a 4:00–4:02 p.m. CT pause Monday to Friday, so even they pause briefly; Hyperliquid publishes no scheduled maintenance window for its BTC book. Liquidity does thin out at weekends. In the year to September 25, 2026, an average weekend day traded 47% of an average weekday's BTC volume on Hyperliquid, and the average daily range was 2.38% at weekends against 3.94% on weekdays. Quiet is not the same as safe: the worst weekend day in that window, Saturday January 31, 2026, closed -6.54% from its open.
Fees, and the maker fee that is not a rebate
As a validator-dex market, BTC pays the standard perp schedule shown in the fee table below, with no HIP-3 multiplier and no growth mode. At the entry tier both sides pay: the maker rate is a fee, not a rebate. Maker rebates on Hyperliquid come only from a separate program for accounts with a large share of maker volume, so a new account placing resting BTC orders should expect to pay the maker rate. On a $10,000 taker fill that is $4.50. Spot Bitcoin on Hyperliquid is a different market: it is the bridged Unit token, deposited from the Bitcoin network with a minimum of 0.0003 BTC and an arrival time of about 30 minutes. Under portfolio margin that spot balance can back perp positions at a loan-to-value of 50%.
