According to @rovercrc, Bloomberg analysts James Seyffart and Eric Balchunas have significantly increased their approval odds for a majority of spot crypto ETF filings to 90% or higher. This optimistic forecast includes potential ETFs for major altcoins such as XRP (XRP), Solana (SOL), Dogecoin (DOGE), Litecoin (LTC), and Cardano (ADA). The analysts cite increased engagement from the U.S. Securities and Exchange Commission (SEC), including the processing of 19b-4 forms and S-1 amendment requests, as a key positive indicator of regulatory cooperation. In contrast, the SUI ETF is given lower odds of 60% due to a lack of regulated futures and regulatory uncertainty, as noted by Bloomberg. This sentiment is mirrored on the prediction market Polymarket, where bettors assign a 98% chance for an XRP ETF approval and a 91% chance for a SOL ETF approval this year.

According to Crypto Rover, citing a Bloomberg analyst, Ethereum (ETH) and Solana (SOL) staking ETFs could be approved as early as June 2025. The analyst highlights that these ETFs may bypass the traditional 19B-4 regulatory process, significantly reducing approval time to just weeks. For traders, this development is critical as it could drive substantial new institutional inflows into both ETH and SOL, likely increasing volatility and trading volume across the crypto market. The rapid ETF approval process may also set a precedent for other crypto-based ETF products, enhancing overall market liquidity and potentially supporting bullish sentiment in the near term (Source: Crypto Rover on Twitter, May 31, 2025).
