The race to launch spot cryptocurrency exchange-traded funds (ETFs) in the United States has entered a new phase, with recent regulatory shifts signaling a more open stance from the Securities and Exchange Commission (SEC). After years of resistance, the approval momentum is building—not just for Bitcoin and Ethereum, but for altcoins like Solana (SOL), Litecoin (LTC), and XRP. With multiple issuers now actively pursuing spot ETFs for these digital assets, and key applications officially accepted by the SEC, the market is watching closely.
This evolving landscape reflects broader changes within the U.S. regulatory environment. Following leadership transitions at the SEC, including Gary Gensler’s departure, the agency has signaled a willingness to clarify its approach to crypto ETF approvals. A newly formed crypto task force has emphasized the need for transparent rules—opening the door for greater institutional participation.

Solana (SOL) Spot ETF: Five Major Firms in the Running
Solana has emerged as one of the most promising candidates for the next wave of spot crypto ETFs. As of early 2025, five major financial firms have formally submitted applications for a SOL-based ETF: Grayscale, Bitwise, VanEck, 21Shares, and Canary Capital.
While all five filed preliminary documents last year, initial attempts were met with rejection. However, in a significant shift, Cboe BZX Exchange resubmitted 19b-4 filings on behalf of Bitwise and VanEck on January 29, 2025, reigniting hopes for approval.
What sets Grayscale apart is its strategy of converting an existing Solana Trust into a spot ETF—a model that proved successful with Bitcoin after a landmark court victory. The SEC’s recent acceptance of Grayscale’s 19b-4 filing marks a pivotal development.
“This could be a positive signal for anyone facing SEC litigation—or any exchange—especially given the SEC previously claimed Solana was a security,” said Bloomberg analyst James Seyffart.
Eric Balchunas, senior ETF analyst at Bloomberg, echoed this sentiment: “This is the first time the SEC has acknowledged an ETF application tracking an asset it once labeled a security. Just six weeks ago, they asked CBOE to withdraw their Solana filing. We’re clearly in new territory.”
The next critical deadlines for SEC action are March 30 and April 3, 2025—dates that could determine whether Solana becomes the third major cryptocurrency (after BTC and ETH) to receive formal ETF backing.
XRP Spot ETF: Broad Institutional Interest Builds
XRP is also gaining traction in the ETF pipeline. Five institutions—Grayscale, Bitwise, Canary Capital, 21Shares, and WisdomTree—have filed applications for a spot XRP ETF.
Grayscale submitted its 19b-4 form on January 30, 2025, aiming to convert its XRP Trust into an exchange-traded product. Shortly after, on February 6, Cboe BZX filed on behalf of Bitwise, 21Shares, and Canary Capital, signaling coordinated institutional interest.
Once the SEC confirms receipt, the application will be published in the Federal Register, triggering a 21-day public comment period. From there, the SEC has up to 240 days to make a final decision, with potential extensions at 45-, 90-, and 60-day intervals.
Despite past regulatory challenges—including the high-profile Ripple lawsuit—the renewed push suggests growing confidence that XRP’s legal standing may now support ETF approval.
Litecoin (LTC) Spot ETF: First Mover Advantage?
When it comes to progress, Litecoin appears to be leading the pack. Among all altcoin ETFs, only Grayscale and Canary Capital have filed for an LTC-based product—but both have achieved a crucial milestone: SEC acceptance of their 19b-4 filings.
Grayscale submitted its application on January 24, 2025, while Canary Capital filed earlier on January 16. Both are now in the 21-day public comment phase, a standard step before deeper regulatory review begins.
Eric Balchunas remains optimistic: “I still believe Litecoin will be the next approved spot crypto ETF.” His reasoning? LTC’s long-standing reputation as a “silver to Bitcoin’s gold,” its established market presence, and relatively clear regulatory history compared to other altcoins.
With no major legal disputes clouding its status—and strong support from early movers—the path for an LTC ETF may be smoother than for others.

Beyond SOL, XRP, and LTC: The Expanding Crypto ETF Landscape
The momentum isn’t limited to just three assets. The broader market is seeing a surge in innovative ETF proposals:
- In January 2025, Rex filed applications for thematic crypto ETFs, including a Trump-themed token ETF and one based on the meme coin BONK.
- On February 10, New York Stock Exchange Arca submitted a 19b-4 form for a Dogecoin (DOGE) spot ETF, reigniting interest in the popular meme currency.
- Meanwhile, 21Shares filed an S-1 registration statement for a Polkadot (DOT) spot ETF, marking another step toward diversified on-chain exposure.
These developments indicate that investor demand—and issuer innovation—is expanding rapidly beyond core assets.
Frequently Asked Questions (FAQ)
Q: What is a spot crypto ETF?
A: A spot crypto ETF holds actual cryptocurrency rather than futures or derivatives. It provides investors with direct exposure to price movements without requiring them to manage private keys or use exchanges.
Q: Why does SEC acceptance of a 19b-4 filing matter?
A: Acceptance means the SEC will formally review the proposal. It triggers publication in the Federal Register and starts the public comment process—a necessary step before potential approval.
Q: How long does the SEC take to approve a crypto ETF?
A: The full review can take up to 240 days. The SEC often uses multiple extension periods (typically 45 + 45 + 90 + 60 days) to evaluate risks related to market manipulation, custody, and investor protection.
Q: Could Solana really be considered a security?
A: The SEC previously suggested Solana might qualify as a security due to its initial distribution model. However, accepting a SOL ETF application implies a shift in enforcement posture—even if not an official policy change.
Q: Is Litecoin more likely to get approved than other altcoins?
A: Many analysts think so. LTC has no ongoing litigation, a transparent issuance model, and strong network fundamentals—factors that align well with SEC expectations for market integrity.
Q: Will XRP benefit from the Ripple vs. SEC case outcome?
A: Yes. The partial ruling in favor of Ripple—that XRP sales on exchanges aren’t securities—has strengthened arguments for XRP’s classification as a commodity, improving ETF prospects.
Final Outlook: A New Era for Crypto ETFs
The accelerating pace of spot crypto ETF applications—and the SEC’s increasing engagement—signals a turning point in digital asset regulation. With SOL, LTC, and XRP all advancing through formal channels, and major asset managers doubling down on innovation, 2025 could mark the beginning of a diversified crypto ETF ecosystem.
Whether Litecoin breaks through first or Solana captures investor imagination, one thing is clear: the era of Bitcoin-only crypto ETFs is ending.
