The Nasdaq Crypto Index has expanded from five to nine digital assets, adding Ripple (XRP), Solana (SOL), Cardano (ADA), and Stellar Lumens (XLM). This expansion is pending SEC approval for the Hashdex NCIQ ETF to align its portfolio with the updated index. Currently, the ETF can only hold Bitcoin and Ethereum due to SEC regulations. Nasdaq filed a proposed rule change on March 7, with a decision expected by November 2, 2025, while Hashdex employs a sampling strategy to manage its current allocations.
