Primary sources: Hyperliquid funding, Hyperliquid contract specifications, and the current OKX contract/funding pages for the exact instrument you intend to trade. Hyperliquid facts checked July 15, 2026.
Journey: Hyperliquid guide hub. Next: export and normalize Hyperliquid funding history before opening either leg.
Get the sign right
- Positive funding: longs pay shorts.
- Negative funding: shorts pay longs.
- If HL is +0.03% per normalized eight hours and OKX is +0.01%, short HL receives the larger amount while long OKX pays the smaller amount.
- The gross spread is approximately 0.02% per normalized interval before fees and basis movement.

Expected net = funding received − funding paid − entry fees − exit fees − slippage − transfer costs − basis loss
The risks the “market-neutral” label hides
- Funding reversal: the spread can shrink or change sign while both legs remain open.
- Basis risk: the two perpetual prices and oracle/mark systems can diverge.
- Liquidation mismatch: equal notional does not mean equal margin safety.
- Execution leg risk: one order can fill while the hedge does not.
- Transfer risk: rebalancing collateral across venues is not instantaneous.
- Operational and custody risk: one venue can reject orders, enter maintenance, or restrict access.
- Contract mismatch: quote currency, multiplier, and funding caps can differ.
Controlled execution workflow
- Confirm both contracts reference sufficiently comparable underlying exposure.
- Calculate equal delta using actual contract size, not equal margin deposits.
- Use small isolated positions first so one venue cannot consume unrelated collateral.
- Prefer limit execution when the spread is wide enough to wait, but define how long one leg may remain unhedged.
- Reconcile fills and notional immediately after entry.
- Monitor the next funding estimates on both venues and define an exit threshold before opening.
- Keep enough free collateral on both sides to survive basis movement.
- Close both legs in a controlled sequence and reconcile funding, fees, and slippage.
When to skip the trade
Skip it when the spread is smaller than conservative round-trip costs, the instruments are not equivalent, either book is thin, collateral cannot be rebalanced safely, or the expected return depends on a single unusually high funding print persisting.
Next step: use the funding history and cost guide and review isolated versus cross margin before testing a two-venue hedge.
