Sei Network SEI token ETF targets October 2026 effective date

REX Shares and Osprey Funds have filed a post-effective amendment for a proposed exchange-traded fund (ETF) that offers exposure to the Sei Network SEI token while incorporating staking rewards. The filing sets a target effective date of October 23, 2026, under the ETF Opportunities Trust.

The proposed REX-Osprey SEI + Staking ETF is designed to hold SEI and stake a portion of its holdings through the Sei Network’s proof-of-stake system, allowing the fund to generate income from staking yields. This development is part of a broader movement toward crypto ETFs that target individual proof-of-stake ecosystems, alongside similar filings for assets such as AVAX, SUI, NEAR, and HYPE.

While the October 23 date is a target for effectiveness, it does not guarantee that trading will commence immediately. The fund managers must still fulfill various listing and operational requirements, with potential trading occurring on exchanges such as Cboe BZX. Additionally, Canary Capital has advanced its own proposal for a staked SEI ETF, indicating growing institutional interest in the asset.
