GraniteShares has postponed the launch of its planned 3x leveraged XRP ETF from April 23 to May 7 due to a delay in the SEC review process. According to NS3.AI, the ETF aims to provide investors with both 3x long and 3x short exposure to XRP. GraniteShares is utilizing a Rule 485 filing, which allows the company to adjust launch dates without having to restart the entire review process.
