The explosive growth of cryptocurrency exchange-traded funds (ETFs) has reshaped the digital asset landscape, with Bitcoin (BTC) and Ethereum (ETH) leading the charge. Now, a new wave of altcoin ETFs is gaining momentum, as regulatory clarity and market demand converge to open doors for broader crypto adoption.
Bitcoin’s spot ETF approval on January 10, 2024, marked a turning point. Since then, BTC has surged 144%, reaching an all-time high of $112,000** in May 2025. The launch of **11 spot Bitcoin ETFs**, authorized by the U.S. Securities and Exchange Commission (SEC), unlocked **$45.3 billion in net inflows, amassing over $130 billion in total net assets.
Leading the pack is BlackRock’s iShares Bitcoin Trust (IBIT), which reached $70 billion** in assets just **341 days** after launch—five times faster than State Street’s gold ETF (GLD), previously the fastest-growing ETF. Fidelity’s FBTC follows with **$20 billion, cementing institutional confidence in Bitcoin as a long-term store of value.
Ethereum ETFs, approved in July 2024, have seen a more modest reception. Despite holding $10.7 billion** in net assets, they’ve attracted only **$3.86 billion in net inflows. ETH’s price has underperformed, trading around **$2,500**—down **28.5%** since ETF approval and still **48.4%** below its 2021 peak of $4,880.
However, recent developments hint at a shift. Ethereum ETFs have recorded zero outflows since May 15, contrasting with Bitcoin’s periodic outflows. A pivotal factor? The SEC’s evolving stance on staking.
“Node operators and validators… would not be considered ‘the offer and sale of securities’,” stated the SEC’s Division of Corporation Finance in a May 2025 staff release. This positions staking akin to mining—potentially paving the way for staking-enabled Ethereum ETFs and unlocking billions in passive yield opportunities.
This regulatory thaw has energized issuers to pursue ETFs for major altcoins. With Bitcoin and Ethereum setting the precedent, the next frontier is clear: Solana (SOL), Ripple (XRP), Litecoin (LTC), and even meme coins like Dogecoin (DOGE) are now in line for approval.
Solana Leads the Altcoin ETF Charge
Among potential altcoin ETF candidates, Solana (SOL) stands out with a 90% probability of approval according to Polymarket. Multiple asset managers—including Fidelity, Bitwise, 21Shares, VanEck, Franklin Templeton, and Grayscale—have filed active S-1 registration forms with the SEC.
Recent signals suggest approval may be near. The SEC has requested amended filings within a week, a historical indicator of impending decisions. Bloomberg ETF analysts Eric Balchunas and James Seyffart predict a “potential altcoin ETF summer,” with Solana likely leading the pack.
“ETFs tracking broad crypto indexes may be approved within the next month. The agency may also act early on spot Solana and staking ETF filings,” they noted.
Solana’s high-performance Layer 1 blockchain, known for speed and scalability, gained massive traction during the 2024 meme coin surge. Its native token, SOL, ranks as the 6th-largest cryptocurrency by market cap at $76 billion**, currently trading at **$144.40—down 50.6% from its January 2025 peak.
The launch of Solana futures by CME earlier in 2025 mirrors the path taken by Bitcoin and Ethereum before their ETF approvals, further strengthening the case for regulatory greenlight.

Ripple’s Legal Wins Boost XRP ETF Prospects
Ripple (XRP) is another top contender, with Polymarket pricing in an 89% chance of ETF approval in 2025. The 4th-largest crypto by market cap at $125.7 billion**, XRP trades at **$2.14, still below its all-time high of $3.40 from 2018.
XRP’s path has been shaped by legal progress. After years of litigation with the SEC, Ripple reached a $50 million settlement, though judicial approval remains pending. This week, both parties jointly requested the court to lift injunctions and finalize the agreement—potentially closing one of crypto’s longest-running legal battles.
Bloomberg’s Seyffart remains confident:
“I would be absolutely stunned if the SEC blocked a spot XRP or Solana ETF.”
ETF filings for XRP have been submitted by Bitwise, Franklin Templeton, Grayscale, CoinShares, and others. Ripple CEO Brad Garlinghouse believes XRP could capture 14% of the global payments sector within five years, emphasizing liquidity over messaging in cross-border transactions.
With strong retail support and corporate adoption—firms like Wellgistics and Webus integrating XRP into treasury strategies—the stage is set for a potential price breakout post-ETF approval.
Litecoin’s Bitcoin Parallels Strengthen Its Case
Litecoin (LTC) rounds out the top three altcoins likely to receive ETF approval, with Polymarket odds at 77% and Bloomberg analysts estimating a 90% chance.
Filings have been submitted by Canary Capital, CoinShares, and Grayscale. Notably, while the SEC delayed decisions on Solana and XRP ETFs last month, it left Litecoin’s timeline untouched—interpreted by markets as a positive signal.
The SEC has acknowledged LTC as “highly similar to Bitcoin,” bolstering its regulatory standing. Launched in 2011 by Charlie Lee as “silver to Bitcoin’s gold,” Litecoin features faster block times (2.5 minutes) and uses the Scrypt algorithm instead of SHA-256.
Though its market cap stands at $6.37 billion** and price at **$83.90—down 80% from its 2021 peak—Litecoin’s mature infrastructure and role as a Bitcoin testnet for upgrades like SegWit and Lightning Network make it a trusted legacy asset for institutions.
Beyond Blue-Chips: The Broader Altcoin ETF Pipeline
The ETF wave is expanding beyond top-tier altcoins. Assets like Cardano (ADA), Avalanche (AVAX), Polkadot (DOT), Sui (SUI), Hedera (HBAR), and TRON (TRX) each have around a 75% approval probability.
Multi-asset ETFs are also emerging. Grayscale’s Digital Large Cap Fund (GDLC)—holding BTC, ETH, XRP, SOL, and ADA with $800 million AUM—could see early approval as a diversified entry point.
Meme coins are not being left behind. Dogecoin (DOGE), with a $26.3 billion market cap, has an 80% chance of ETF approval. Filings have been submitted by Bitwise, Grayscale, and 21Shares. Rex Shares and Osprey have even filed for ETFs tied to Bonk (BONK) and political-themed tokens like TRUMP, signaling investor appetite for niche narratives.
“The return dispersion ripe for active [management]. Could produce the next star manager,” said Balchunas, predicting a rise in actively managed crypto ETFs before meme coin products go mainstream.
Regulatory Shift Fuels the Crypto ETF Surge
Over 100 crypto ETF applications are now under SEC review—a surge driven by evolving policy under Chairman Paul Atkins, sworn in April 2025. Atkins has championed a “rational, coherent” regulatory approach, distancing from prior enforcement-heavy tactics.
Recent SEC roundtables have addressed DeFi, tokenization, custody, and securities definitions—signaling a shift toward enabling innovation rather than stifling it. Self-custody has been affirmed as a “foundational American value,” and staking regulations are being reconsidered for legislative backing.

Final Outlook: A New Era for Crypto Investing
The crypto ETF revolution began with Bitcoin but is rapidly expanding. While no altcoin will match BTC’s scale—$2 trillion market cap and $50 billion daily volume—the ETF effect can still trigger massive rallies across smaller assets.
With regulatory tailwinds, institutional interest, and growing retail demand, Solana, XRP, Litecoin, and even meme coins are poised for their moment. As multi-asset and actively managed ETFs emerge, investors will gain more sophisticated tools to navigate the space.
