Bloomberg Analysts Unveil Highly Optimistic Forecast
Bloomberg Intelligence ETF analysts Eric Balchunas and James Seyffart have published a comprehensive chart detailing the likelihood of spot cryptocurrency ETF approvals in the United States by the end of 2025. The data, released on April 30, assigns a 90% probability to Solana (SOL) and Litecoin (LTC), as well as to a digital asset index basket. XRP (XRP) follows at 85%, while Dogecoin (DOGE), Polkadot (DOT), Cardano (ADA), Hedera (HBAR), and Avalanche (AVAX) range between 75% and 80%. The analysts note that all 19b-4 filings for these assets have been formally acknowledged by the U.S. Securities and Exchange Commission (SEC), with decision deadlines stretching from July to December 2025.
SEC Delays and Commodity Classification
On the same day, the SEC delayed rulings on the Franklin Templeton XRP ETF and the Bitwise Dogecoin ETF, a move that market participants interpret as routine rather than a negative signal. Analysts emphasize that the SEC is expected to classify SOL, LTC, XRP, and others as commodities, a designation that has historically paved the way for spot ETF approvals. Furthermore, most of these assets already have regulated futures markets, which satisfies a key requirement the SEC has used in previous Bitcoin and Ethereum ETF approvals. This regulatory tailwind underpins the high probability estimates.
Polymarket Predictions Align with Traditional Analysis
Decentralized prediction market Polymarket reflects a similar surge in confidence. As of April 30, the Solana ETF contract showed an 89% chance of approval by year-end, up 15% with a total volume of $142,806. Litecoin and XRP both trade at 79% on Polymarket, with respective volumes of $42,181 and $65,640. Particularly notable is the Cardano bet: while its Polymarket odds lag at 69%, it has attracted the highest total volume ($366,581) among all crypto ETF contracts, indicating intense trader interest despite the more conservative Bloomberg estimate of 75%. The convergence of traditional analyst models and prediction market data strengthens the case that 2025 could be a historic year for altcoin ETFs.
What Lies Ahead for Crypto ETFs
Investors are now watching closely as SEC deadlines approach. With Bitcoin and Ethereum spot ETFs already commanding billions in daily trading volume, the approval of Solana, Litecoin, XRP, and others would represent a major expansion of the crypto ETF ecosystem. Such approvals would unlock institutional capital flows into a wider array of digital assets, potentially triggering a new market rally. However, analysts caution that the SEC's delayed decisions—combined with the volatile political landscape of a U.S. election year—could still alter the timeline. The second half of 2025 remains the decisive window for the crypto ETF narrative to become reality.
