Nasdaq has filed a proposal with the U.S. Securities and Exchange Commission (SEC) to expand its digital asset benchmark index from five to nine cryptocurrencies. The proposed additions include XRP, Solana (SOL), Cardano (ADA), and Stellar (XLM). This expansion would allow the Hashdex Nasdaq Crypto ETF (NCIQ) to transition from the current NCIUS index to the broader Nasdaq Crypto Index (NCI). The SEC's decision on this proposal is expected by November 2, 2025. The inclusion of these assets reflects their growing prominence, with current ETF holdings showing Bitcoin (BTC) at 74.9%, Ethereum (ETH) at 11.6%, XRP at 5.9%, Solana at 4.9%, and Cardano at 1.4%. Separately, Canary Capital has registered multiple staking ETFs in Delaware, including the Canary Marinade Solana Staking ETF and a staked Injective (INJ) ETF, indicating a potential expansion of staking-focused investment products in the U.S. market.
