BREAKING: REX Shares Files for Revolutionary BNB Staking ETF with SEC

Wall Street meets crypto staking as REX Shares drops regulatory paperwork for what could become the first BNB-focused staking ETF.

The Regulatory Play

Filing with the SEC signals serious institutional intent—REX isn't just dabbling. They're positioning at the intersection of traditional finance and yield-bearing digital assets.

Why BNB Matters

BNB's ecosystem dominance and built-in staking mechanics make it a prime candidate for ETF treatment. This isn't just another crypto fund—it's a targeted play on blockchain's utility token economy.

The Bottom Line

If approved, this ETF would let investors capture staking yields without the technical headaches of direct blockchain involvement. Finally, traditional finance might actually understand crypto's value proposition—though they'll probably still take their 2% management fee for the privilege.

Staking integrated into ETF design

The proposed fund will use a C-corporation and a Cayman Islands subsidiary to custody and stake BNB (BNB). This structure ensures compliance while distributing staking rewards, typically 3-5% annualized yield on the BNB Chain, back to shareholders in the FORM of dividends.

Custody and staking services would likely be handled by a regulated partner such as Anchorage Digital, as seen in Rex’s solana product.

Bloomberg ETF analyst Eric Balchunas highlighted the filing on Aug. 27, noting its similarities to Rex’s Solana (SOL) Staking ETF, which launched earlier in 2025 and quickly grew to more than $133 million in assets under management.

If approved, the BNB Staking ETF could launch within weeks, making it one of the first U.S.-regulated investment products offering direct exposure to staked BNB.

BNB’s growing role in institutional portfolios

The filing coincides with a spike in institutional interest in BNB. By the second quarter of 2025, more than 30 publicly traded companies had allocated close to $800 million in BNB as a treasury asset.

For example, corporate purchasers Nano Labs and BNB Network Company have positioned BNB as a diversification asset. BNB is more appealing for yield-based products because of its limited supply, continuous token burns, and inexpensive transaction costs.

But approval isn’t guaranteed. Due to concerns about market manipulation and custody, the SEC has previously postponed applications for Avalanche (AVAX) and Cardano (ADA) ETFs. However, Rex’s filing shows that altcoin ETFs are gaining traction and could be a game-changer for integrating BNB into the mainstream financial industry.
