Cardano's ADA has met the U.S. SEC futures-trading requirement tied to spot ETF listing eligibility after CME ADA futures completed six months of trading on Aug. 9, CryptoSlate reported. Under the SEC's general listing standards, cryptocurrencies that have traded for at least six months on a regulated futures market can qualify as eligible underlying assets for spot exchange-traded products, a threshold meant to show market maturity and resistance to manipulation. That means any new issuer seeking to launch a spot ADA ETF would likely face a lighter regulatory review process, although the milestone does not amount to approval of any specific filing. The development came two days after Grayscale withdrew its application for a spot ADA ETF, and no asset manager currently has a pending application for a single-asset spot ADA ETF.
