REX Shares and Osprey Funds have filed a registration statement for a new exchange-traded fund that provides investors with exposure to the Sei asset. The product is slated to officially take effect on October 23, 2026.
Why it matters
The fund is designed to integrate spot-asset access with staking rewards, allowing investors to capture yield from the underlying token within a traditional exchange-traded product structure.
The registration covers a combined financial vehicle offering Sei exposure and staking functionality within one exchange-traded product. This filing represents the first step toward official market entry.
The players
REX Shares
REX Shares is an investment firm that specializes in developing exchange-traded products and innovative financial vehicles.
Osprey Funds
Osprey Funds is an asset management firm focused on providing investment access to digital assets and cryptocurrency markets.
The details
This new ETF seeks to bridge the gap between digital asset ownership and staking rewards by embedding the functionality directly into the fund structure. By consolidating these features, the firms aim to offer a streamlined method for accessing Sei through standard investment accounts.
Timeline
The registration statement for the new ETF is set to take effect on October 23, 2026.
Market Dynamics
The introduction of this product follows the established precedent of spot Bitcoin ETFs providing regulated access to digital assets, though this fund extends the model by adding staking capabilities. This reflects a broader trend of issuers attempting to capture yield for investors within traditional market wrappers.
Investors may eventually gain a regulated way to earn staking rewards on Sei without managing private wallets or complex technical infrastructure. The fund potentially offers a simpler alternative for retail portfolios interested in yield-generating digital assets.
The takeaway
This registration highlights the increasing sophistication of crypto-based exchange-traded products seeking to replicate yield-generating mechanics. Investors should monitor the final regulatory status and associated fee structures as the product nears its expected launch date.
What happens next
The REX-Osprey SEI + Staking ETF is scheduled to reach its effective date on October 23, 2026, marking the next milestone in its regulatory timeline.
