The Nasdaq Crypto ETF expansion plan is accelerating, aiming to include nine tokens such as Solana (SOL), Cardano (ADA), and XRP in its benchmark index to promote portfolio diversification. Currently, the Hashdex Nasdaq Crypto Index ETF (NCIQ) is limited to holding BTC and ETH, but the SEC accepted its rule change application in June 2025. If approved, it will allow investment in all index component assets, with results expected to be announced by November 2, 2025. This move will enhance institutional capital allocation efficiency, reduce tracking error risks, and may trigger passive capital inflows for newly included tokens like SOL. As a key node in the integration of traditional finance and the crypto market, the expansion of this ETF could become a landmark event for regulatory breakthroughs in the crypto industry in 2025.
