REX Shares and Osprey Funds have submitted an updated filing for a proposed SEI Staked ETF, pushing forward one of the more niche staking-wrapped fund structures currently working through the regulatory pipeline. The update signals continued intent from both firms, though an amended submission does not constitute approval, listing, or any guarantee that the product will reach investors.
REX Shares and Osprey Funds have been active in the staking ETF space, previously pursuing staking-wrapped structures for other proof-of-stake assets. The SEI Staked ETF represents an extension of that strategy to the SEI network, a layer-1 blockchain with its own native staking mechanism.

An updated filing indicates the proposal remains active and that the firms are refining the structure in response to feedback or procedural requirements. It does not mean a regulator has ruled on the application, assigned an effective date, or approved the fund for trading.

The product name combines two distinct components: spot exposure to the SEI asset and a staking yield layer. In concept, a staked ETF would hold SEI and participate in network validation, passing some portion of staking rewards through to fund shareholders, subject to fees, custody arrangements, and applicable regulations.

Staking yield in proof-of-stake networks is not fixed. Reward rates depend on total network stake, validator performance, and protocol parameters, all of which can change. The final expense ratio, staking mechanics, reward distribution method, and risk disclosures for any live product would only be established in final fund documents, which have not been published based on the available information.

The SEC's ongoing review of Ethereum and Solana staking ETFs from the same firms provides relevant precedent for how regulators are approaching staking yield within a registered fund wrapper, including questions around custody, validator selection, and how rewards are classified.
The amended submission opens a review window during which the regulator may request further amendments, issue comment letters, or allow the filing to go effective. None of those outcomes is guaranteed on any particular timeline.
Investors and DeFi participants tracking this proposal should monitor for: additional amendments to the filing, a regulatory decision or notice of effectiveness, and final prospectus documents that would specify the fund's ticker, exchange listing, fee structure, and staking methodology. Until those documents are public, the product remains a proposal with no confirmed structure.
The broader staking ETF category is still being defined procedurally, and the outcome of related filings, including those for ETH and SOL staking vehicles, may influence how the SEI application is evaluated.
