Ethereum Updates Today: Ethereum ETFs Surpass Bitcoin in Q3 Inflows Amid Rising Interest in Altcoins

During the week ending October 31, 2025, Ethereum ETFs saw net inflows totaling $15.97 million, with Grayscale's

Mini Trust ETF (ETH) leading the sector by bringing in $56.05 million in fresh investments, as reported by . This signals renewed institutional engagement after recent market turbulence. Since its inception, Grayscale's ETH ETF has accumulated $1.54 billion in total inflows, reinforcing its leadership among Ethereum ETFs. At the same time, Ethereum's price climbed to $3,857, while more than $500 million worth of ETH was transferred to long-term wallets, indicating increased institutional accumulation.

The surge in Ethereum ETF activity comes amid a broader wave of optimism in the crypto sector, spurred by the introduction of

(SOL) and (LTC) ETFs. This week saw the debut of Grayscale's Solana ETF (GSOL) and Bitwise's BSOL, with BSOL attracting $129 million in its first two days and GSOL securing $4 million on launch day, according to . Zach Pandl, Grayscale's Head of Research, predicts that U.S. spot Solana ETFs could capture 5% of the token's total supply within one to two years, which would mean over $5 billion in inflows at current valuations, based on data from . This outlook is strengthened by Solana's notable staking rewards, offering a 5.7% annual yield, a feature not available in Bitcoin ETFs.

The momentum behind Ethereum ETFs also reflects a growing institutional interest in altcoins. In Q3 2025, spot Ether ETFs attracted $9.6 billion, outpacing the $8.7 billion that flowed into Bitcoin ETFs, according to

. Experts attribute this trend to increasing regulatory certainty and rising demand for Ethereum's smart contract capabilities. "Institutions started with through ETFs, but are now shifting toward Ethereum, with other altcoins likely to follow," commented Leon Waidmann from Onchain. This movement is supported by Nansen data, which shows that savvy investors are accumulating tokens like (UNI) and (AAVE) in anticipation of further altcoin ETF launches.

Nevertheless, some obstacles remain. Charles Schwab cautioned that despite recent ETF approvals by the SEC, the crypto market is still only lightly regulated, which could pose risks for investors. Furthermore, BlackRock's decision not to file for altcoin ETFs may slow the pace of inflows, as its Bitcoin ETF alone attracted $28.1 billion in 2025, while other Bitcoin ETFs saw net outflows totaling $1.27 billion.

Grayscale's move from trusts to ETFs, as seen with GSOL, has enhanced both liquidity and price transparency, removing the premiums and discounts that often affect closed-end crypto trusts. Pandl noted that diversified crypto ETPs, which provide exposure to several tokens, are likely to become more popular as investors look to simplify their portfolios.

As the crypto ETF market continues to grow, Ethereum and Solana are set to establish distinct positions. Pandl pointed out that, although both are smart contract platforms, their differing architectures allow them to complement each other in institutional portfolios. With Solana ETFs already drawing over $150 million and stablecoin issuance rising on the network, the next stage for the market may depend on regulatory changes and broader economic conditions, according to
