REX Shares and Osprey Funds have submitted an updated filing with the U.S. Securities and Exchange Commission (SEC) for a proposed SEI Staked ETF, marking a continued effort to bring a staking-integrated exchange-traded product tied to the SEI network to U.S. markets. The submission remains a proposal: no approval, launch date, or fund terms have been established.

An Updated Submission, Not an Approval

The filing pairs two firms with established track records in the crypto ETF space. REX Shares has previously brought leveraged crypto ETFs to market, including the Strive 2x Leveraged ETF tracking ASST, while Osprey Funds is a digital asset manager that has pursued SEC-registered crypto investment vehicles. Their collaboration reflects a broader industry push to expand the range of crypto-native products available through regulated brokerage accounts. The filing also lands amid a widening slate of U.S. proposals that would fold staking rewards into exchange-traded structures, an area where regulators have yet to on a uniform approach.

The proposed product is described as a SEI Staked ETF, meaning it would seek exposure to SEI (the native asset of the Sei network, a proof-of-stake layer-1 blockchain) while incorporating staking yield into its structure. The available information does not specify what the updated submission changes or adds relative to any prior version. Readers can search SEC EFTS filings directly to track submission activity.

What Distinguishes a Staked ETF Filing

Staking, in general terms, involves pledging tokens to help operate a proof-of-stake network in exchange for rewards. A staked ETF proposal is structurally distinct from a standard spot ETF because it attempts to capture those network staking rewards inside a regulated wrapper, a design that raises additional questions for the SEC around custody, yield treatment, and investor disclosure. Whether the updated filing addresses those questions in a materially new way remains an open item until the full document is reviewed.

The distinction is significant for creators and digital asset holders tracking infrastructure developments. ETF products tied to proof-of-stake networks introduce questions about who holds validator keys, how rewards are distributed, and whether staking activity affects a fund's tax treatment. None of these are settled matters in U.S. regulatory practice, which is part of why updated filings tend to follow initial submissions. Related regulatory maneuvering around tokenized share structures illustrates how creative product design continues to test SEC boundaries.

What to Watch Next

The next meaningful development would be an SEC response, whether a request for additional information, a comment letter, or a decision. No timeline is established by the available evidence. The filing update confirms that REX Shares and Osprey remain active on the product, but the gap between an updated submission and a tradable ETF remains wide.

Regulatory decisions on staked crypto ETFs will likely carry implications beyond SEI itself, potentially setting precedent for how staking yield is treated inside registered fund structures. That makes this filing worth monitoring even for investors and builders not directly focused on the SEI ecosystem.
