Key Takeaways:

  • REX-Osprey filed with the SEC for a BNB-focused ETF that includes staking rewards, allocating at least 80% of assets to BNB.
  • The ETF would be accessible to retail investors, unlike the earlier BNB Chain Trust limited to accredited investors.
  • The filing reflects a broader trend of crypto ETFs with staking features, following VanEck’s similar proposal and rising sector-wide inflows.

REX Shares and Osprey Funds (REX-Osprey) have filed with the U.S. Securities and Exchange Commission (SEC) to launch a BNB-focused exchange-traded fund (ETF) that incorporates staking rewards, underscoring growing institutional interest in yield-generating crypto products.

The proposed REX-Osprey BNB + Staking ETF would allocate at least 80% of its assets to BNB, the native token of the Binance ecosystem, either directly or through a Cayman Islands subsidiary, while the remainder could be invested in other BNB-related ETFs.

BNB staking on the BNB Chain, which operates under a proof-of-staked-authority mechanism, currently yields 1.5% to 3% annually, potentially appealing to income-seeking investors.

Unlike Osprey’s 2024 BNB Chain Trust, which requires a $10,000 minimum and targets accredited investors, this new ETF aims to be broadly accessible.

The fund plans to stake all BNB holdings, subject to liquidity thresholds set by regulators, with Anchorage Digital Bank serving as custodian.

The filing follows VanEck’s May 2025 application and comes amid record inflows into Bitcoin and Ether ETFs, which have posted all-time high trading volumes.

Analysts suggest that approval of altcoin ETFs -including those tied to Solana, TRUMP, and Sui – could fuel a potential “altcoin season.”
