According to the latest reports, the US Securities and Exchange Commission has officially extended the review period for two key cryptocurrency exchange-traded fund proposals: the Truth Social Bitcoin ETF, now due by September 18, 2025 and the Grayscale Spot Solana Trust ETF, with a new deadline of October 10, 2025.
These are just the latest in a string of crypto ETF delays as the agency takes its time despite political shifts and leadership under SEC Chair Paul Atkins.
Regulatory Momentum: Why the SEC is Pressing Pause
Based on available data, under the Securities Exchange Act, ETF proposals must be decided within 180 days of publication but the SEC can extend this review period up to 240 days for further review. In both filings, the Commission said it needs more time “to consider the proposed rule change and the issues raised therein.”
These extensions join a wave of delayed altcoin ETF decisions across major digital assets, including XRP, DOGE, LTC, and ADA.

The SEC’s growing crypto team, led by Commissioner Hester Peirce, suggests a clarity path will come but not before the agency is satisfied with investor protections, custody protocols and comprehensive endorsements of in-kind redemption systems.
What’s in the Pipeline: Altcoin ETFs Await Approval
Currently, reports say more than 70 crypto ETFs are under review, covering altcoins. The SEC has delayed filings from Grayscale, Bitwise, VanEck, Franklin Templeton, and 21Shares for Solana, XRP, Litecoin, ADA, Dogecoin, and HBAR, among others.
Despite the delays, analysts like James Seyffart and Eric Balchunas previously said the delays are procedural, not hostile. They expect most altcoin approvals to be done by October 2025 as the SEC has been using full review cycles for the past year.
Market Implications: Investors Wait as Strategy Evolves
If altcoin ETFs are approved before year end; early inflows into SOL, XRP, DOGE, LTC and ADA could be seen sparking new institutional demand and diversification beyond Bitcoin and Ethereum exposure.
Ongoing crypto ETF delays may dampen investor enthusiasm, extending uncertainty and delaying mainstream access to regulated altcoin investment vehicles. This could weigh on long-term sentiment and keep inflows focused on existing Bitcoin and Ether products.
With staking provisions, in-kind redemption protocols, and asset-specific compliance under the microscope, the SEC seems to be building a solid legal foundation before granting final approval, trading speed for structure.
US vs Global Crypto ETF Dynamics
While the SEC extends deadlines, Canada, Europe and Australia are already listing altcoin ETFs for Solana, XRP, Dogecoin and Litecoin. These regions have more advanced Micro-Asset frameworks (like MiCA in Europe) than the US. European crypto investment products now account for nearly 30% of its $13 billion ETF market according to ETFBook estimates.

Meanwhile the SEC’s delays continue to restrict US investors from accessing regulated exposure in these tokens and give the competitive advantage to jurisdictions that are faster to altcoin integration.
Conclusion
Based on the latest research, the pattern of crypto ETF delays shows the SEC is using extended review windows to navigate the complexities of staking, custody and trading for altcoin products.
While altcoin ETFs (like Solana, XRP, Litecoin and Dogecoin) are expected to be resolved by Q4 2025, continued delays may stall institutional interest in altcoin funds and keep Bitcoin and Ether as the only regulated crypto entry points.
