REX Shares and Osprey Funds (REX-Osprey) have filed with the US Securities and Exchange Commission for a BNB exchange-traded fund (ETF) featuring staking yield. The filing comes as asset managers step up their push into crypto ETFs and yield-generating strategies.
According to the filing, the REX-Osprey BNB + Staking ETF would allocate at least 80% of its capital to BNB (BNB), the native token of the Binance ecosystem, or gain exposure to the asset through a Cayman Islands subsidiary. The remaining assets could be invested in other ETFs or exchange-traded products offering additional BNB exposure.
BNB staked on the Binance Chain, which uses a proof-of-staked-authority consensus, is estimated to generate annual yields of 1.5% to 3% for the network's validators.
The new ETF, if approved, may differ from the Osprey Funds’ BNB Chain Trust, launched in 2024. While still offering exposure to BNB, the BNB Chain Trust is geared toward accredited investors and has a minimum buy-in of $10,000.
The fund intends to stake all of its BNB, but only if its adviser can keep illiquid assets under 15% of the portfolio, a regulatory threshold designed to ensure investors can still redeem their shares for cash. Anchorage Digital Bank has been appointed custodian for the fund’s BNB, related holdings and liquid staking tokens.
The REX-Osprey BNB + Staking ETF is similar to another BNB ETF filed in May 2025 by asset manager VanEck — the first BNB fund proposed in the United States. VanEck is also seeking permission to capture BNB’s staking yield.
Cointelegraph contacted Osprey for comment but had not received a response at time of publication.

ETF action picks up
According to SoSoValue.com, investor trading within US crypto ETFs has picked up in the past few months. Bitcoin (BTC) ETFs have seen monthly inflows ranging from $3 billion in April to $6 billion in July. Meanwhile, Ether (ETH) ETFs saw a $5.4 billion inflow in July and a $3.7 billion inflow so far in August.
During the week of Aug. 15, Bitcoin and Ether ETFs posted their highest combined trading volume to date. Ether ETFs alone recorded about $17 billion in trades — a figure that, according to a Bloomberg ETF analyst, amounted to “blowing away record.”
As many crypto enthusiasts await “altcoin season,” Bitfinex analysts say a significant rally among such tokens may only happen if more crypto ETFs are approved in the US.
Altcoins featured in ETFs awaiting a decision from the SEC include Solana (SOL), Official Trump (TRUMP), and Sui (SUI).
