REX-Osprey Files for BNB Staking ETF, Tracking Binance Coin and Staking Rewards

Thursday, Aug 28, 2025 6:49 pm ET2min read

REX-Osprey has filed with the SEC for a BNB + Staking ETF, which would track Binance Coin's performance, including staking rewards. The fund plans to invest at least 80% of its net assets in BNB or its subsidiaries, with 20% allocated to other ETFs providing exposure to BNB. The ETF's staking mechanism involves locking BNB tokens to earn transaction fees and network rewards, but poses risks such as slashing penalties and technology vulnerabilities. The filing comes after Solana's success and broader institutional adoption of Binance Coin.

REX-Osprey has filed with the U.S. Securities and Exchange Commission (SEC) for a BNB + Staking ETF, aiming to track the performance of Binance Coin (BNB) and include staking rewards. The fund plans to invest at least 80% of its net assets in BNB or through a Cayman Islands subsidiary, while allocating 20% to other ETFs that provide exposure to BNB. The ETF's staking mechanism involves locking BNB tokens in the BNB Chain’s delegated proof-of-stake validation process to earn transaction fees and network rewards.

The filing comes as BNB reached new all-time highs above $882 in August, driven by record network activity of 16.8 million weekly active users on BNB Chain. The token has emerged as the fourth-largest digital asset with a market capitalization exceeding $119 billion, supported by growing institutional adoption and corporate treasury strategies. Recent SEC guidance on liquid staking provided regulatory clarity that could accelerate approval of staking-based ETF products.

The ETF’s staking component involves locking BNB tokens in BNB Chain’s delegated proof-of-stake validation process to earn transaction fees and network rewards. The fund aims to stake all its holdings while maintaining sufficient liquidity, with staked tokens subject to approximately a seven-day unbonding period. REX-Osprey will delegate BNB holdings to validators through crypto custodian Anchorage Digital Bank, passing all staking rewards, minus fees, directly to investors. This structure includes liquid staking tokens that provide tradeable representations of staked BNB, enabling yield generation without complete illiquidity.

However, staking presents multiple risk factors, including slashing penalties for validator misbehavior that could result in significant principal losses. The concentration of BNB Chain validation among Binance-related entities creates governance risks, while technology vulnerabilities could compromise staked assets. The fund must also find its way around the 15% illiquid asset limits imposed by SEC regulations, which may potentially constrain staking levels during certain market conditions.

Despite these complexities, institutional demand for yield-generating crypto products has grown as traditional fixed-income returns remain compressed. Staking rewards offer regular income streams that align with institutional investment mandates, which require cash flow generation beyond price appreciation.

Institutional interest in BNB has accelerated through corporate treasury adoption strategies pioneered by holders of Bitcoin and Ethereum. BNC Network Company recently purchased 200,000 BNB, worth approximately $160 million, becoming the largest corporate holder of Binance Coin outside of exchange operations. Similarly, Windtree Therapeutics signed a $60 million securities purchase agreement with options for an additional $140 million to implement BNB-focused treasury strategies. If completed, the biotechnology firm would become the first Nasdaq-listed company with direct BNB holdings, potentially inspiring similar corporate adoption.

Most recently, B Strategy has launched a $1 billion BNB treasury vehicle that aims to become the “Berkshire Hathaway of the BNB ecosystem” through a listing on U.S. public markets. The initiative combines Asia-Pacific liquidity networks with American regulatory frameworks, backed by family offices connected to Binance founder Changpeng Zhao.

The corporate adoption wave occurs alongside Binance’s expansion into Islamic finance through Sharia Earn, a compliant staking platform serving 31 countries. The $4 trillion Islamic finance market was seen as a massively untapped demand for halal crypto products that avoid interest-based returns.
