The Nasdaq Crypto ETF expansion plan is accelerating, planning to include 9 tokens such as Solana (SOL), Cardano (ADA), and XRP into 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 has accepted its rule change application as of June 2025, and if approved, 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 a passive influx of funds into newly included tokens such as SOL. As a key node in the integration of traditional finance and the crypto market, this ETF expansion may become a landmark event for regulatory breakthroughs in the crypto industry in 2025.
