What is Costco?
Costco Wholesale runs membership-only warehouse stores that sell groceries, household goods, electronics and fuel in bulk at low margins. Membership fees make up a large part of its profit. Costco shares trade on the Nasdaq under the ticker COST, and one contract references one share.
The xyz:COST perpetual tracks the share price of Costco, settles in USDC and never expires. It is listed on XYZ, a builder exchange: a market run by an outside team on Hyperliquid's order book. You can go long or short with up to 20× leverage, around the clock.

Size a COST trade from its stop
Hypurr Desk asks where your stop goes and how much of your account you are willing to lose there, then works out the size. An example at 1,012.0, from when this page was built:
- Account
- $1,000.00
- Risk
- 1% = $10.00
- Stop
- 2% below entry, at 991.76
- Size
- 0.4723 COST ($478.09)
- Loss at the stop, fees included
- $10.00
- Leverage
- 18× isolated, $26.56 margin
The stop sets the loss, not the leverage: leverage only decides how much margin the position ties up. Move the stop and the size follows, so a wider stop means a smaller position and the same loss. The stop is placed on the exchange with the entry. How risk sizing works.
Questions about COST
What is the maximum leverage on COST?
20×. Hypurr Desk sizes each order from your stop, so the leverage follows from how much you choose to risk.
How often is funding paid on COST?
Every hour. When the rate is positive, longs pay shorts; when it is negative, shorts pay longs. The current rate is shown at the top of this page.
What does it cost to trade COST on Hypurr Desk?
At the exchange's base tier, 0.034% of the position value for market orders and 0.028% for limit orders that rest on the book, including the 0.025% Hypurr Desk fee. There is no subscription and no sign-up.
Can I trade Costco when its home market is closed?
Yes. The perpetual trades around the clock, every day, including weekends and holidays. Prices can jump when the main market reopens, so a stop may fill away from its price.
Do I own Costco when I trade this market?
No. A perpetual tracks the share price of Costco and settles gains and losses in USDC. You never hold any shares, and positions can be closed out if losses use up their margin.
