The Nasdaq Crypto ETF expansion plan is accelerating, aiming to include nine tokens such as Solana (SOL), Cardano (ADA), and XRP in the benchmark index to promote diversification of holdings. 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. 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 risk, and may trigger a wave of passive fund inflows for newly included tokens like 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.
