Massive Crypto ETF Push: REXShares and Osprey File for 21 Altcoin Funds, Including Staking Products

The competition to dominate the U.S. Exchange-Traded Fund (ETF) market has dramatically intensified, with REXShares and Osprey Funds jointly filing applications for an unprecedented total of 21 new cryptocurrency ETFs.

This massive proposed lineup is noteworthy for its sheer scale and for introducing yield-generating products to the mainstream market.

Highlights of the New ETF Filings:

• Breadth of Assets: The applications span a wide range of altcoins, from established projects like Cardano (ADA), Avalanche (AVAX), and Polkadot (DOT), to newer tokens such as Hyperliquid (HYPE), Sei (SEI), and Ethena (ENA).
• Staking Integration: Several key proposed funds are structured to include staking rewards, offering investors access to yield-generating strategies through regulated ETF vehicles. These include the ADA + Staking, AVAX + Staking, and DOT + Staking ETFs.
• Other Dedicated Funds: The list also features dedicated products for tokens like Chainlink (LINK), Litecoin (LTC), and Stellar (XLM), alongside emerging projects like TAO and SUI.

Market analysts are highlighting the scale of the initiative, which comes shortly after the SEC finalized new general rules to streamline the listing process for crypto spot ETFs.

This strategic timing, following the success of Bitcoin and Ethereum ETFs, could position REXShares and Osprey to capture significant institutional and retail interest. If approved, the launch of 21 funds in one sweep would represent one of the largest single expansions of regulated crypto investment products in U.S. history.
