October 2025 could be a defining month for the cryptocurrency market, with the U.S. Securities and Exchange Commission (SEC) approaching final decisions on 16 different exchange-traded fund (ETF) filings. Unlike previous cycles that focused mainly on Bitcoin and Ether, this new batch includes altcoins such as Solana, XRP, and Litecoin, signaling growing diversification in investor demand.
This week’s “Byte-Sized Insight” dives into why this wave of ETF proposals feels different, how recent regulatory developments could reshape the process, and what the potential outcomes might mean for investors and the broader crypto space.
A shift inside the SEC
On September 17, the SEC approved a new framework known as “generic listing standards” for exchange-traded products tied to spot commodities — a move that includes digital assets. Experts believe these updated standards could greatly simplify the approval process, removing the need for individual rule changes that have historically delayed crypto-related ETFs from entering traditional finance.
The timing also reflects a broader political transformation. According to Zach Pandl, Head of Research at Grayscale, the Trump administration’s arrival brought new momentum toward regulatory clarity.
“President Trump and his administration came in with a clear message from voters — they wanted transparency and a clear rulebook for crypto in the U.S.,” Pandl explained. “We’re now seeing coordinated efforts across the White House, Congress, and regulators like the SEC to respond to that.”
He added that bipartisan cooperation has strengthened confidence among both companies and investors that crypto is now a permanent part of the U.S. financial landscape.
Beyond Bitcoin: demand for altcoin exposure
The big question is how much investor appetite truly exists for non-Bitcoin ETFs. Bloomberg Intelligence ETF analyst James Seyffart noted that Solana and XRP are the most promising candidates, largely because they already have established futures markets. However, he warned against assuming they will attract the same scale of inflows as Bitcoin ETFs.
“They’ll likely perform well in terms of assets and volume,” Seyffart said, “but the real opportunity may lie in diversified or index-style products.”
Pandl agreed, referencing Grayscale’s latest crypto index fund. “We’re not just focused on single-asset products anymore — we’re also working on diversified crypto ETPs that can give investors a broader, more balanced exposure,” he said.
What could follow approval
If the SEC gives the green light, Seyffart expects a wave of innovation across the ETF landscape.
“You’ll start seeing everything from staking-based Solana ETFs to covered call products, leverage, and inverse plays. It’s going to evolve rapidly,” he predicted.
Whether October brings immediate market impact or simply sets the stage for long-term growth, one thing is clear: the regulatory tide is turning. For the first time, altcoin ETFs may finally be on the verge of joining Bitcoin in mainstream U.S. markets.
