#XRPETF Spot XRP ETF Filings: As of March 2025, nine firms, including Grayscale, Bitwise, Franklin Templeton, and ProShares, have filed for spot XRP ETFs, with Franklin Templeton’s filing on March 11 storing XRP at Coinbase Custody. XRP leads altcoins with 10 active ETF filings, compared to Solana’s five. The SEC’s final deadlines for these applications stretch into October 2025, with some as early as May 22. Polymarket bettors estimate a 79-82% chance of approval by year-end, boosted by Coinbase’s regulated XRP futures product launch.
