REX Shares and Osprey Funds have filed an N-1A registration statement with the U.S. Securities and Exchange Commission seeking approval for the Rex-Osprey BNB Staking ETF. The proposed fund would offer U.S. investors spot exposure to Binance Coin (BNB) while capturing additional yield from staking rewards, a feature not available in existing crypto ETFs. The application is structured under the Investment Company Act of 1940, mirroring the route used for recently-filed Solana products. If the SEC grants clearance, the ETF could begin trading as early as 9–10 November 2025, according to a timeline outlined in the filing.
