Defiance Daily Target 2X Long OKLO ETF (OKLL) is an exchange-traded fund that seeks daily investment results, before fees and expenses, equal to 200% of the daily percentage change in the share price of Oklo Inc. (NYSE: OKLO), a nuclear technology company developing advanced fission power plants and fuel recycling systems using high-assay low-enriched uranium (HALEU) fuel. The fund achieves its leveraged exposure through derivatives including swap agreements with counterparties such as Cantor, Marex, Clearstreet and Nomura, as well as United States Treasury Bills and cash equivalents; it does not invest directly in OKLO shares and is designed for short-term trading rather than long-term holding due to daily reset and compounding effects that may cause performance divergence over extended periods. OKLL operates within the leveraged equity segment of the ETF market, targeting sophisticated investors and active traders seeking amplified bullish exposure to OKLO's stock price movements without requiring a margin account.
Launched on June 23, 2025, OKLL forms part of a suite of first-mover single-stock leveraged ETFs introduced by Defiance ETFs in June 2025, including products like IONZ (2X short IonQ) and SOUX (2X long SoundHound AI), marking the issuer's expansion into targeted high-growth technology and innovation themes. Defiance ETFs, founded in 2018 and headquartered in Miami, Florida, specializes in thematic, income and leveraged ETFs with approximately $7.78 billion in total assets under management across 65 funds as of late 2025. The fund has exhibited significant volatility and performance swings, including a since-inception market price return of around 269% as of mid-November 2025, alongside monthly gains exceeding 100% in September 2025 and over 60% in early October 2025, driven by OKLO's momentum from U.S. Department of Energy selections for advanced nuclear projects and strategic deals such as a clean energy agreement with the U.S. Air Force.
OKLL trades on U.S. exchanges including Nasdaq with assets under management reaching $121.82 million, a net expense ratio of 1.31% and monthly distribution frequency, available to investors in the United States. The fund's portfolio includes top holdings like Oklo Inc. swaps comprising over 200% notional exposure offset by short cash positions, reflecting its leveraged structure. Defiance ETFs positions OKLL as a tactical tool for short-term speculators capitalizing on nuclear energy sector catalysts, amid broader industry tailwinds for advanced fission technologies.
