How to short on Hyperliquid

There is no borrowing step

If you have shorted equities, most of the mechanics you learned do not apply here. There is no stock loan, no locate, no borrow fee and no recall risk.

A perpetual is a contract on a price. Taking the short side is simply agreeing to the other end of it, collateralised in USDC. The interface treats it as a button: Sell instead of Buy.

That makes shorting mechanically identical to going long, which is worth stating plainly because the perceived difficulty puts people off a position that is no harder to open than the one they already know how to open.

The two real differences

Funding usually flows the other way

When the funding rate is positive, longs pay shorts every hour. Crypto perpetuals spend a lot of their time with positive funding, because retail positioning leans long.

So a short is often a position that pays you to hold it. That is genuinely different from a long, and it is the reason funding arbitrage exists at all.

The rate is not a constant. It moves with positioning and it flips sign, so a short entered because the funding was attractive can end up paying it. How the rate is set covers the mechanism.

The loss side has no ceiling

A long can lose its whole value if the price reaches zero. That is a bounded worst case.

A short loses as the price rises, and a price has no upper bound. In theory the loss is unlimited.

Opening one

1. Pick a perpetual market

   Spot is buy and hold; there is no short side. Check the market is a perpetual before anything else. The markets page lists them with their volume and funding.

   You should see a perp market, not a spot pair

2. Check the funding rate and which way it points

   Positive means you are paid. Negative means you pay, and a strongly negative rate on a crowded short is a warning rather than an opportunity.

   You should see a clear view of whether this short will be paid or charged hourly

3. Set isolated margin and modest leverage

   Isolated caps what this position can cost. For a short, the liquidation sits above your entry, and that is the number to watch.

   You should see a liquidation price far above the current price

4. Choose Sell and place the order

   A limit order rests and pays the maker fee; a market order fills now and pays taker. Nothing about shorting changes the fee side.

   You should see a short position showing a negative size

5. Attach a stop above your entry

   For a short, the stop goes above the current price and the take-profit below it, which is the reverse of a long. Putting them on the wrong side is the most common rejection. Setting them properly.

   You should see a trigger order in the TP/SL column, above the market

Reading funding as a crowding signal

This is where shorts get useful information that longs often ignore.

Strongly negative funding means shorts are crowded and paying to stay. That is the setup for a short squeeze: any rise liquidates some of them, their forced buying pushes the price up, and it cascades. High open interest alongside makes it worse.

Strongly positive funding means longs are crowded and paying you. More comfortable to sit in, and the mirror risk applies to them.

Neither predicts direction. Both tell you where the forced buying or selling would come from, which is more useful than a prediction.

What it costs to hold

Three costs, and for a short they do not all point the same way.

Trading fees are identical to a long: 0.045% taker at the entry tier, or 0.0432% with a referral code.

Funding is a cost or a payment depending on the sign. Use the funding calculator with the real rate rather than assuming.

The spread you cross on both sides, which is set by depth rather than by any fee schedule.

Where shorting suits and where it does not

It suits hedging a spot holding you do not want to sell, expressing a view that something is overpriced, and collecting funding when the rate is strongly positive and you can hedge the direction elsewhere.

It does not suit a beginner’s first position. Not because the mechanics are harder — they are identical — but because the crowded-short squeeze is a failure mode that punishes exactly the people who have not yet learned to read funding and open interest together.
