The crypto investment landscape could be on the brink of a major expansion, as leading ETF analysts now estimate a 95% chance that spot ETFs for Solana (SOL), Ripple (XRP), and Litecoin (LTC) will gain approval from the U.S. Securities and Exchange Commission (SEC) in 2025. This optimistic forecast marks a significant shift in market sentiment and regulatory expectations.
Rising Confidence in Altcoin ETF Approvals
Bloomberg Intelligence’s renowned ETF experts, Eric Balchunas and James Seyffart, recently updated their projections on X (formerly Twitter), signaling growing confidence in the SEC’s willingness to greenlight a new wave of cryptocurrency-based exchange-traded funds. On June 30, they raised the approval probability for spot ETFs tied to Solana, XRP, and Litecoin from 90% to 95%—a near-confirmation level in regulatory forecasting.

Seyffart noted, “We expect a new wave of ETFs in the second half of 2025.” This sentiment reflects a broader trend: increasing institutional acceptance and regulatory clarity around digital assets. The analysts also assigned the same 95% likelihood to ETFs based on diversified crypto baskets or indices—products designed to track multiple digital assets rather than a single coin.
For Solana, XRP, and LTC, final SEC decisions are expected by October 2025. Meanwhile, crypto basket ETFs could see approvals as early as this week, according to the analysts’ timeline.
Broader Altcoin ETF Momentum Builds
The momentum isn’t limited to just three assets. Balchunas and Seyffart have also upgraded the approval odds for several other altcoin spot ETFs to 90%, including:
- Dogecoin (DOGE)
- Cardano (ADA)
- Polkadot (DOT)
- Hedera (HBAR)
- Avalanche (AVAX)
These products are anticipated to receive final rulings during the fourth quarter of 2025. While not yet at the 95% threshold, the upward revision underscores a clear pattern: the SEC appears increasingly open to expanding the crypto ETF universe beyond Bitcoin and Ethereum.
However, not all filings are viewed equally. Canary Capital’s proposed ETFs for Sui (SUI) and Tron (TRX) face steeper hurdles, with approval probabilities estimated at just 60% and 50%, respectively. These lower odds may reflect concerns over market maturity, liquidity, or regulatory scrutiny surrounding the underlying networks.
Back in June, Balchunas coined the phrase “brace for a potential altcoin ETF summer,” suggesting that approvals could come in rapid succession. Seyffart echoed this, stating that an ETF tracking a broad crypto index might be approved as soon as next month.
Solana Staking ETF Set to Launch
In a landmark development, the REX Osprey Solana Staking ETF is scheduled to begin trading on Wednesday—making it the first U.S.-listed ETF to offer exposure to crypto staking rewards.
This product allows investors to gain indirect exposure to Solana’s network while earning yield through staking—a feature previously unavailable in regulated ETF structures. Initially, the SEC raised concerns about whether the fund qualified as an investment company under the Investment Company Act of 1940.
To address these concerns and secure approval, the issuer agreed to allocate at least 40% of its assets to other exchange-traded products (ETPs), most of which are registered outside the United States. This structural compromise appears to have satisfied regulators—at least for now.

The launch sets a precedent for future products incorporating yield-generating mechanisms, potentially paving the way for Ethereum staking ETFs and other income-focused crypto funds.
SEC Delays Continue on Ethereum Staking
Despite progress on Solana, the SEC remains cautious when it comes to Ethereum-based staking. On the same day the Osprey Solana ETF was confirmed, the commission delayed its decision on whether Bitwise’s spot Ethereum ETF can include staking functionality.
This hesitation highlights an ongoing regulatory divide: while Bitcoin is widely treated as a commodity, Ethereum’s classification—and by extension, its staking mechanism—remains a gray area. The SEC may be wary of endorsing yield-bearing securities that blur the line between passive investment and active participation in network validation.
Additionally, the agency postponed approval for the Osprey Bitcoin Trust to list and trade its shares on a national securities exchange—an unusual move that suggests continued scrutiny over even established players in the space.
Frequently Asked Questions (FAQ)
Why are Solana, XRP, and Litecoin ETFs more likely to be approved?
Analysts believe these assets have strong liquidity, established market presence, and sufficient trading volume—key criteria the SEC evaluates. Additionally, after approving Bitcoin and Ethereum ETFs, the SEC may feel more confident expanding into major altcoins.
What does a 95% approval probability mean?
A 95% chance indicates near-consensus among experts that approval is highly likely. However, it’s not a guarantee—regulatory shifts or legal challenges could still alter outcomes.
How do staking ETFs work?
Staking ETFs invest in cryptocurrencies that support proof-of-stake consensus. The fund earns rewards by participating in network validation, distributing those yields to shareholders over time—offering passive income within a regulated framework.
Will more altcoins get ETFs after 2025?
Yes—analysts expect continued momentum. If SOL, XRP, and LTC ETFs perform well, demand for DOGE, ADA, DOT, and others will grow. Regulatory clarity could accelerate filings across dozens of digital assets.
Are crypto basket ETFs safer than single-asset ETFs?
Diversified crypto basket ETFs spread risk across multiple assets, potentially reducing volatility. They may appeal to conservative investors seeking broad exposure without concentrating on one coin.
What’s stopping lower-profile coins like SUI or TRX from getting approved?
Coins with smaller market caps, lower liquidity, or regulatory uncertainty face higher barriers. The SEC prioritizes investor protection, so it tends to favor more mature and transparent projects first.
Final Outlook: A New Era for Crypto Investing
The rising approval odds for altcoin ETFs signal a maturing market. With Solana leading the charge through its innovative staking model, and major players like XRP and Litecoin close behind, 2025 could mark the beginning of a multi-asset crypto ETF era.
Investors should watch key deadlines in Q3 and Q4 closely. Approvals for DOGE, ADA, DOT, and others would not only validate individual projects but also reinforce the long-term viability of crypto as an asset class.
