Different platforms settle funding rates at different times. The key alignment method for cross-platform arbitrage is: convert both funding rates into an "hourly rate" before comparing, instead of directly comparing single settlement amounts. You also need to know each platform's settlement time so you can execute accurately before and after settlement.
Why different settlement times cause problems
Hyperliquid settles its funding rate every hour, while major centralized exchanges such as Binance and OKX usually settle every 8 hours (00:00, 08:00, 16:00 UTC).
If the rate is positive on Hyperliquid and also positive on Binance, Hyperliquid's hourly payment speed is 8 times faster than a typical centralized exchange. This means the same directional exposure held for 8 hours on Hyperliquid can create several times more funding cost than on a centralized exchange. A single settlement amount cannot be compared directly.
Alignment method: convert to an hourly rate
When you pull real-time funding rates from both sides with an API, divide Binance's rate by 8 (for 8-hour settled contracts) to get an hourly rate. Then compare it with Hyperliquid's rate.
Conversion logic: compare the "hourly funding rate," not the "single settlement rate." If the difference between the two exceeds a threshold (for example, an hourly rate difference above 0.02%), there may be a possible arbitrage window.
Settlement time alignment: watch for shifted settlement windows
Different platforms settle at different times. Besides converting the rate, you also need to know both settlement schedules, so you can evaluate the net funding gain before and after each settlement.
Binance USD-M perpetual contracts settle at UTC 00:00, 08:00, and 16:00. Some 1-hour settlement contracts have their own schedule. OKX defaults to 8-hour settlement, but in extreme market conditions it may automatically adjust to 4-hour or 1-hour settlement. Hyperliquid settles hourly.
Complete operation process
1. Monitor rates in real time. Use APIs to pull real-time funding rates from both sides, convert them into hourly rates, and filter coins where the difference exceeds your threshold.
2. Open positions on both sides. Short on the platform with the higher funding rate (you receive funding), and go long on the platform with the lower funding rate (you pay less). The two sides offset market direction risk, and the net gain comes from the rate difference.
3. Calculate settlement times across platforms. The two funding rates settle separately at their own settlement times, not at the same time. You only pay or receive funding if your position is open across that settlement point, so include both settlement schedules in your calculation.
4. Monitor and exit. Keep watching the funding rate difference on both sides. If the difference falls below your threshold, or if the rate flips on one side, close both positions and exit the arbitrage.
Risk reminder: Funding rate arbitrage is not risk-free. In practice, you still face cross-platform deposit and withdrawal costs and delays, margin requirements on both sides, price slippage and taker fees, and the risk of technical failure on a single platform. Hyperliquid's hourly settlement also requires more frequent monitoring and execution.
Next steps
Before running any cross-platform funding rate arbitrage, check the target coin's funding rate settlement schedule on both platforms (on Binance, check the contract info page; on Hyperliquid, use the metaAndAssetCtxs endpoint from the API). Use the hourly rate as the common comparison basis, not the single settlement amount.
