@REXShares and @OspreyFunds have submitted an updated filing with the U.S. Securities and Exchange Commission (SEC) for a staked SEI exchange-traded fund, with October 23, 2026, set as the official effective date for a suite of crypto altcoin ETFs.
The updated registration is not limited to Sei Network alone. According to the amended filing, the funds covered include the REX-Osprey $SEI + Staking ETF, $SUI + Staking ETF, $HYPE + Staking ETF, $NEAR + Staking ETF, $AAVE ETF, $ADA + Staking ETF, $ATOM + Staking ETF, and $AVAX + Staking ETF. The document states that this revision is solely to designate a new effective date for previously submitted post-effective amendments.
The registration covers spot exposure funds for $SEI, $SUI, $NEAR, $AVAX, $ATOM, and $ADA, with embedded staking features designed to generate yield for investors alongside standard price exposure. A standalone $AAVE ETF and a $HYPE + Staking ETF round out the lineup.
The structure of these products marks a notable shift in how institutional-grade crypto funds are being designed. Rather than tracking token prices alone, the staking ETFs aim to pass validator-derived rewards directly to investors. As noted in prior REX-Osprey fund documents, staking rewards are paid in the reference asset and passed through to the fund after custodian and validator fees are deducted.
The move reflects a broader push by the pair to establish what could be described as an institutional Staking-as-a-Service model, offering regulated, exchange-traded access to on-chain yield without requiring investors to manage wallets or validators directly. Sei Network confirmed the filing amendment on September 28, 2026.
REX Shares and Osprey Funds have been among the most active filers in the U.S. crypto ETF space, having previously launched products covering Solana, Ethereum, and Dogecoin under their joint REX-Osprey brand.
