Nasdaq has taken a significant step towards bringing Dogecoin (DOGE) into the mainstream with its formal SEC filing to list and trade the 21Shares Dogecoin Exchange Traded Fund (ETF). This application kicks off a review process that, if successful, could see the popular memecoin gain greater prominence in traditional financial markets. The SEC will now review this application and publish it for public comment before making a final decision on approval or denial of the ETF. 21Shares’ earlier S-1 filing, submitted separately in April, further signals the company’s ambition to offer institutional investors a way to gain exposure to Dogecoin without directly holding the token.
