The U.S. Securities and Exchange Commission (SEC) is set to issue final decisions on at least 16 spot altcoin ETF applications in October 2025, covering assets including SOL, XRP, LTC, DOGE, ADA, and HBAR.

The SEC has accelerated its review process, shortening the timeline to under 75 days through new universal listing standards, and has withdrawn 19b-4 filings from some issuers.

Key decision dates include: Canary's LTC ETF (October 2), Grayscale's Solana and LTC trust conversions (October 10), and WisdomTree's XRP fund (October 24).

Market expectations are high for Litecoin and SOL ETF approvals: Polymarket data shows a 93% probability for LTC, while Bloomberg analysts see near-certain approval for SOL.

If approved, these ETFs could bring capital inflows to altcoins, though institutional investors may prefer multi-crypto portfolio products over single-token ETFs—potentially altering altcoin price appreciation patterns.

In October 2025, the U.S. SEC will deliver final rulings on at least 16 spot cryptocurrency ETF applications covering tokens beyond Bitcoin and Ethereum, such as SOL, XRP, LTC, DOGE, ADA, and HBAR. Recent developments show the SEC withdrawing multiple delay notices and accelerating the approval process via new universal listing standards, compressing review timelines to under 75 days.

According to crypto reporter Eleanor Terrett, the SEC has requested issuers of LTC, XRP, SOL, ADA, and DOGE ETFs to withdraw their 19b-4 filings, as these are no longer necessary following the adoption of universal listing standards.

Since their approval, Bitcoin and Ethereum spot ETFs have seen significant capital inflows, substantially boosting their prices. The key questions now are whether these new altcoin ETFs will be approved and if they will similarly drive price appreciation.

Multiple Altcoin ETF Final Deadlines Fall in October

Data compiled by Twitter user Jseyff shows that final deadlines for several altcoin spot ETFs are scattered throughout October. The first pending decision is Canary's LTC ETF, with a deadline of October 2.

Next are Grayscale's Solana and LTC trust conversions on October 10, followed by WisdomTree's XRP fund on October 24.

According to a list of upcoming approvals created by Bloomberg ETF analyst James Seyffart, decisions could be announced any time before the final deadlines.

Applications have been submitted by institutions including Grayscale, 21Shares, Bitwise, Canary Capital, WisdomTree, and Franklin Templeton. Notably, BlackRock and Fidelity are absent from this round, but this doesn't diminish the potential impact—approvals could pave the way for larger-scale products in the future.

Since the BTC and ETH spot ETFs, no other cryptocurrencies have received SEC approval, with the SEC repeatedly delaying decisions as in the past. However, the impending final rulings must deliver a clear "Yes" or "No" to the market.

The market awaits with bated breath.

The approval or rejection of the first-mover Litecoin and SOL ETFs will likely set expectations for subsequent applications.

Probability of Approval

In late July, the SEC's new listing standards primarily focused on eligibility requirements and operational mechanisms for crypto ETPs. Firstly, in-kind creation and redemption were formally permitted, meaning authorized participants can exchange ETP shares using actual crypto assets rather than cash.

The SEC also announced listing standards for spot ETFs. These new standards are expected to take effect in October 2025, aiming to streamline the ETF listing process. The "universal listing standard" requires crypto assets to have been listed on futures markets of major exchanges like Coinbase for at least six months. This rule ensures sufficient liquidity and market depth to prevent manipulation.

Litecoin, known as a long-established altcoin, stands as a prime candidate for initial approval due to its maturity and non-security status. Litecoin founder Charlie Lee stated in a recent interview that he expects a spot LTC ETF to launch soon. This view is based on the SEC's approval of universal listing standards for crypto ETFs and LTC's inclusion among the ten qualifying assets.

Charlie Lee discussed LTC's prospects within the evolving regulatory framework. He noted that the SEC's recent approval of universal crypto ETF listing standards was a key catalyst, emphasizing that Litecoin meets the conditions for expedited approval.

Currently, Polymarket betting shows the probability of a Litecoin spot ETF approval this year has risen to 93%.

Regarding the SOL spot ETF, Bloomberg ETF analyst Eric Balchunas stated, "To be honest, the success rate for a SOL spot ETF approval is now close to 100%. The universal listing standard makes the 19b-4 filings and their deadlines meaningless. Now it's just about the S-1 forms. The baby could arrive any day now—be ready."

Notably, ADA is the last asset awaiting a decision at the end of October, with Polymarket odds for its ETF approval also at 93%.

Clearly, the SEC's decisions in early October will set the tone.

Previously, the SEC approved the Hashdex Crypto Index ETF. Recently, the Hashdex Nasdaq Crypto Index US ETF (NCIQ) added support for XRP, SOL, and XLM, enabling the product to provide US investors with exposure to five crypto assets—BTC, ETH, XRP, SOL, and XLM—through a single investment vehicle.

The SEC also previously approved the conversion of the Bitwise 10 Crypto Index Fund into an ETF, covering assets including BTC, ETH, XRP, SOL, ADA, SUI, LINK, AVAX, LTC, and DOT.

Will Approval Boost Prices?

Bitfinex analysts previously predicted that crypto ETF approvals could trigger a new altcoin season or rally, providing traditional investors with more avenues for crypto exposure.

However, not all analysts agree.

Bloomberg ETF analyst James Seyffart noted that the current market dynamic represents an "altcoin season" shaped by Digital Asset Trust Company (DATCO) structures rather than traditional token price increases. Seyffart pointed out that institutional investors prefer multi-crypto portfolio products over single altcoin ETFs. He emphasized that institutional capital favors gaining crypto exposure through regulated products rather than direct token ownership—a structural shift that could permanently alter altcoin appreciation patterns.
