On June 2, 2024, Nasdaq submitted a rule change proposal to the SEC, seeking to include XRP, SOL, XLM, and ADA in its digital asset benchmark index, and to allow the Hashdex Nasdaq Crypto ETF (NCIQ) to shift from the current NCIUS index to the broader Nasdaq Crypto Index (NCI), which includes nine digital assets. If approved, the ETF would be permitted to invest in all nine cryptocurrencies, including the newly added four. The SEC’s final decision deadline is November 2, 2025.
