REX-Osprey Staked SEI ETF Effective Date
Sei (SEI) · Listings & TGEs · October 23, 2026
REX Shares and Osprey Funds set October 23, 2026 as the effective date of their Staked SEI ETF filing, a US ETF with spot SEI and staking.
REX Shares and Osprey Funds have updated their Staked SEI ETF registration with the US SEC, setting October 23, 2026 as the effective date. The proposed exchange-traded fund would give US investors spot exposure to SEI, the native token of the Sei layer-1 blockchain, with staking rewards, and was filed alongside similar staked products for NEAR, HYPE, SUI and AVAX. A competing Canary Capital Staked SEI ETF (S-1 Amendment No. 2, custody with BitGo, ~90% staked) is also in review. An effective date on a filing is not a guaranteed trading start: sponsors can amend or delay it, so treat October 23 as the scheduled date for a first US staked SEI ETF.
