On September 5, 2023, Nasdaq recently submitted an application to the U.S. Securities and Exchange Commission (SEC) to include XRP, Solana (SOL), Cardano (ADA), and Stellar (XLM) in its cryptocurrency index (NCI) to expand the coverage of Hashdex's Nasdaq Cryptocurrency Index U.S. ETF (NCIQ). If approved, this ETF will shift from tracking only Bitcoin (BTC) and Ethereum (ETH) to include 9 mainstream cryptocurrencies, providing broader exposure to digital assets. The SEC is expected to make a decision by November 2, 2025. Market analysis suggests that this move could drive institutional funds into the altcoin market, enhance liquidity, and further facilitate the integration of cryptocurrencies with traditional finance.
