ETF Opportunities Trust - REX-Osprey DOGE ETF is a United States-domiciled, non-diversified exchange-traded fund launched in September 2025 and listed on Cboe BZX Exchange under the ticker DOJE. The Fund seeks to provide investment results, before fees and expenses, corresponding to the performance of Dogecoin (DOGE); offers brokerage-account-based exposure to spot DOGE price movements; invests, under normal market conditions, at least 80% of net assets, plus borrowings for investment purposes, in DOGE and other assets providing DOGE exposure; may hold DOGE directly, invest through the wholly owned REX-Osprey DOGE Subsidiary organized in the Cayman Islands, and utilize DOGE-linked exchange-traded products, futures contracts, swap agreements and other derivatives; and may hold foreign securities and cash or cash-equivalent instruments. The Fund is advised by REX Advisers LLC and is offered through ETF Opportunities Trust, whose principal executive offices are in Richmond, Virginia. REX-Osprey is a strategic collaboration between REX Shares, an alternative-strategy ETF and ETN provider, and Osprey Funds, a digital-asset-focused investment firm. The Fund targets U.S. investors seeking regulated, exchange-traded exposure to the Dogecoin ecosystem without directly purchasing or custodying DOGE. In September 2025, REX-Osprey launched DOJE alongside the REX-Osprey XRP ETF, positioning DOJE as the first U.S.-listed ETF designed to offer spot Dogecoin exposure and the first U.S. memecoin ETF. Effective May 10, 2026, the Fund amended its investment objective, replacing its prior objective of seeking 1x the performance of Dogecoin with an objective of seeking the performance of Dogecoin, in each case before fees and expenses.
