Roundhill Uranium ETF (UX), a series of Roundhill ETF Trust, provides investors with targeted exposure to the price of physical uranium (U3O8), the primary raw material in the nuclear fuel cycle, through swap agreements and related derivatives; these include Spot Uranium Derivatives referencing the daily settlement price of front-month UxC Uranium U3O8 Futures published by CME Group, as well as swaps and direct holdings linked to Uranium Companies such as Yellow Cake Plc and Uranium Trusts such as the Sprott Physical Uranium Trust; the ETF also invests in U.S. Treasury securities and money market funds for collateral purposes, with Spot Uranium Derivatives held via a Cayman Islands subsidiary to comply with regulatory limits; it maintains a gross expense ratio of 0.75%, trades on Cboe BZX Exchange with options availability, and distributes annually. Launched on January 29, 2025, and managed actively by Roundhill Financial Inc. (investment adviser) and Exchange Traded Concepts LLC (sub-adviser), UX represents the first U.S.-listed ETF to directly target physical uranium pricing, distinguishing it from equity-based uranium funds focused on miners. Headquartered in New York and founded via Roundhill Investments (established 2018), the non-diversified fund concentrates over 80% of net assets (valued at notional for derivatives) in uranium-linked instruments, serving institutional and retail investors seeking commodity exposure amid rising nuclear energy demand from AI data centers and global electrification. In a major strategic development, UX commenced trading in January 2025 as Roundhill's innovative pure-play vehicle for uranium spot price tracking, leveraging swaps primarily on Sprott Physical Uranium Trust (holding 66.1 million lbs U3O8 as of November 2024, stored in Canada, U.S., and France) and Yellow Cake (holding 20.2 million lbs as of March 2024); no subsequent acquisitions, partnerships, funding rounds, or product launches have been reported through late 2025. The ETF's performance remains highly sensitive to uranium market volatility, supply concentrations in Kazakhstan, Canada, and Australia, and reference asset risks, with no material operational changes or reorganizations noted post-launch.
