REX-Osprey Staked SEI ETF Sets November 20 as Effective Date

The first US staked SEI ETF is scheduled to become effective on November 20, 2026, according to a filing by REX Shares and Osprey Funds with the US SEC. The fund gives brokerage account holders exposure to Sei (SEI), the token of the Sei layer-1 blockchain, plus staking rewards. The sponsors set the date in an October 22 amendment covering 21 of their funds, according to the SEC filing.

When Does the Staked SEI ETF Take Effect?

The REX-Osprey SEI + Staking ETF lists November 20, 2026 as its effective date. The same sponsors had set October 23 before the October 22 amendment. The filing covers 21 REX-Osprey funds at once, including staked products on NEAR, HYPE, SUI and AVAX. Sei runs a proof-of-stake network, so the fund can hold the token and earn staking rewards at the same time. Sei is one of the layer-1 blockchains built for trading, and traders can follow the token on the SEI price chart.

How the REX-Osprey SEI + Staking ETF Works

The fund holds spot SEI and adds staking rewards to the position, so investors get the token's price plus the yield the network pays to stakers. US investors can already buy SEI on crypto exchanges. The ETF moves that exposure into a regular brokerage account and handles the staking. Rewards come from the network itself: staking secures the Sei ecosystem and pays SEI to the addresses doing the work, and the fund passes those rewards to its investors.

A Second SEI ETF Is Still in Review

Canary Capital is pursuing its own Staked SEI ETF. Its S-1 Amendment No. 2, with BitGo as custodian, is still in review with the SEC, and about 90% of its portfolio is designed to be staked. The REX-Osprey fund is the one with a set effective date today.
