- The SEC will decide on multiple altcoin ETF applications, including Solana and index funds, by July 2, 2025.
- Bloomberg analysts assign a 90% approval chance for at least some spot altcoin ETFs, led by Solana.
- ETF filings surged 300% in 2025, signaling growing institutional interest in regulated altcoin exposure.
Several ETF proposals are awaiting the SEC’s response, including filings by Grayscale and Bitwise for Solana and crypto index funds. These applications, which seek to track the performance of Solana and multiple cryptocurrencies, have received increased attention from regulators. Notably, analyst Eric Balchunas reported that fund issuers were recently instructed to update their registration filings, particularly for Solana-linked products.
This move signals an active review phase by the SEC. Among the proposals under review are spot Ether staking ETFs and basket funds covering multiple altcoins. The SEC’s decision deadline for many of these applications falls on July 2, making the coming weeks critical for market participants watching closely for approval signals.
SEC Eyes Altcoin ETFs in July Shift
The U.S. Securities and Exchange Commission is preparing to decide on a new wave of cryptocurrency exchange-traded fund (ETF) applications this July. At the center of this development is the growing interest in altcoin-based ETFs, particularly those tied to Solana and broader crypto index products.
For the first time, mainstream investors could soon gain regulated access to a wider set of digital assets beyond Bitcoin and Ethereum. This possible expansion into Solana and other altcoins marks a major shift from previous SEC actions, which had largely restricted crypto ETFs to Bitcoin products. The growing regulatory consideration for altcoins has been referred to as the potential start of an “Altcoin ETF Summer,” according to Bloomberg Intelligence.
Altcoin ETF Filings Surge Amid Rising Institutional Interest
As of mid-2025, ETF filings have jumped to 72 submissions, a 300 % increase compared to the previous year. More than half of these applications focus on Solana and XRP, reflecting a clear institutional interest in altcoin exposure. This sharp rise in filings follows the earlier approval of spot Bitcoin ETFs in January, which led to $7 billion in net inflows and a 40% increase in assets under management.
Importantly, this inflow was driven by institutions previously hesitant due to regulatory uncertainty. If altcoin ETFs receive approval, they may follow a similar trend in attracting significant capital. Market observers have linked this filing surge to growing clarity from the SEC around crypto-related investment vehicles.
Altcoin ETF Hopes Rise as SEC Decision Nears
After the approval of Bitcoin spot ETFs, fund assets grew to $167 billion by May, illustrating strong demand for regulated crypto exposure. This historical precedent is now shaping expectations for altcoin ETFs. According to Bloomberg, staking features for Ethereum and diversified crypto index offerings are gaining regulatory consideration, especially with updated issuer filings.
Grayscale and Bitwise remain among the key applicants pursuing these new ETFs, aiming to provide safer market access without requiring direct token ownership. Their filings include plans for diversified crypto baskets, offering exposure to several digital assets through a single investment vehicle. The SEC’s decision on these products, expected in early July, could define the scope of retail and institutional participation in altcoins moving forward.
