OKX announces the listing of SEI perpetual futures, margined in USDT, available from November 14, 2025. The trading option includes leverage and 24/7 trading hours.

Cryptocurrency exchange OKX has revealed its plans to list USDT-margined perpetual futures for SEI, set to go live on November 14, 2025, at 07:30 UTC. This move marks an expansion of OKX’s derivatives offerings, catering to traders interested in SEI pairs.

Details of the SEI Perpetual Futures

The newly introduced SEI/USDT perpetual futures will feature a settlement in USDT, with a face value of 10. Traders can utilize leverage options ranging from 0.01x to 50x. The trading hours for these futures are set to be 24/7, providing continuous access to the market.

Pricing for the futures will be based on the SEI/USDT index, with SEI’s value calculated in USDT equivalents. The funding rate for these futures will be determined by a formula that considers the average premium index and interest rate, clamped within a range of 1.50% to -1.50%. Details on the funding rate mechanism can be found in OKX’s product documentation.

Funding Fee Settlement and Trading Agreement

The funding fee for the SEI perpetual futures will be settled every four hours. However, if the funding rate reaches its cap or floor, the settlement interval may adjust to hourly. This automatic adjustment is part of OKX’s strategy to maintain market stability and can be further explored in their product documentation.

Traders interested in participating must adhere to the OKX Perpetual Futures Trading User Agreement, which outlines the terms and conditions of trading on the platform.

According to OKX, this addition aims to enhance the trading experience by providing more flexible and diverse financial instruments. It reflects the growing interest and demand for SEI within the crypto derivatives market.
