Rex-Osprey, a leading digital asset investment firm, has formally submitted a filing to the U.S. Securities and Exchange Commission (SEC) for approval of the REX-Osprey BNB + Staking ETF. The proposed fund aims to provide investors with exposure to Binance Coin (BNB) while offering the potential to earn staking rewards from the BNB Chain. This marks a notable expansion in the ETF landscape, extending staking-based products beyond Rex-Osprey’s earlier Solana Staking ETF.
The BNB-focused ETF is designed to allocate at least 80% of its assets directly into BNB or via a Cayman Islands subsidiary. The remaining portion may be invested in BNB-linked exchange-traded products (ETPs), providing portfolio flexibility. With Binance Coin operating on a proof-of-staked-authority (PoSA) consensus, the staking component is expected to generate annual yields ranging between 1.5% and 3%.
Dual Strategy Balances Yield and Liquidity
To address liquidity risks associated with staked assets, the ETF will cap staked positions at 15% of the total portfolio. Rex-Osprey also plans to incorporate liquid staking tokens (LSTs), enabling staked holdings to remain tradable and accessible. This dual strategy balances yield generation with investor redemption needs, making the ETF appealing to both retail and institutional participants.
Anchorage Digital Bank, a federally chartered crypto custodian, will serve as the official custodian for both BNB and LST holdings. This ensures a secure regulatory framework for investors, reinforcing confidence in the product’s compliance and asset safety.
Regulatory Pathway Mirrors Solana Staking ETF
The proposed BNB ETF will follow the same Investment Company Act of 1940 registration pathway as Rex-Osprey’s Solana Staking ETF, which has already attracted strong institutional demand. Analysts expect that, if approved, the BNB Staking ETF could start as early as November 9 or 10, 2025, signaling growing interest in staking-enabled ETFs among institutional investors.
The filing comes shortly after VanEck submitted a similar BNB-focused ETF application, highlighting increasing competition in the market. Financial firms are racing to develop first-to-market products that combine regulated ETF structures with staking rewards.
Expanding Digital Asset Investment Options
Historically, cryptocurrency ETFs have predominantly focused on Bitcoin and Ethereum. However, growing investor demand for diversified exposure to other major blockchain ecosystems has encouraged firms like Rex-Osprey to innovate. By targeting BNB, the world’s fourth-largest cryptocurrency by market capitalization, Rex-Osprey is offering a regulated pathway for institutional and retail investors to gain exposure to both the asset and its staking rewards.
The ETF’s staking feature allows investors to capture additional yield while holding BNB, differentiating it from traditional crypto ETFs. This approach may appeal to investors seeking passive income strategies alongside exposure to a high-profile cryptocurrency.
Market Outlook and Industry Implications
If approved, the REX-Osprey BNB + Staking ETF could position Rex-Osprey as a pioneer in the growing niche of staking-enabled ETFs. Analysts suggest that regulated staking products could see significant adoption as investors increasingly prioritize both compliance and yield generation.
The start also reflects a broader trend in the digital asset sector: the integration of staking mechanisms into mainstream investment products. As cryptocurrencies like BNB continue to gain traction among institutional investors, ETFs that incorporate staking rewards may become a standard feature in the market.
Moreover, the introduction of staking-enabled ETFs could accelerate the evolution of the broader digital asset ecosystem, attracting investors who prefer regulated investment vehicles over direct crypto holdings. By combining exposure, yield, and regulatory safeguards, products like Rex-Osprey’s ETF provide a compelling value proposition for a diverse investor base.
Strategic Expansion for Rex-Osprey
For Rex-Osprey, the BNB Staking ETF represents a strategic expansion of its product lineup following the strong reception of its Solana Staking ETF. The firm’s ability to combine innovative ETF structures with staking rewards could solidify its leadership in the digital asset investment space.
As the SEC review progresses, market participants will be watching closely to see if BNB joins the growing list of cryptocurrencies available through regulated ETFs. The approval of such products may set a precedent for future staking-based ETFs and further legitimize the integration of blockchain assets into traditional investment portfolios.
Ultimately, Rex-Osprey’s filing underscores a key development in the evolution of cryptocurrency investment products, highlighting staking as a vital feature for investors seeking exposure, income, and regulatory compliance in the digital asset market.
