The US spot Bitcoin exchange-traded funds (ETFs) have witnessed significant outflows, with $60.4 million leaving the funds on Monday, December 8, 2025. This marks a challenging day for Bitcoin-focused ETFs, despite notable contributions from funds like BlackRock’s IBIT. In contrast, altcoin ETFs, particularly those tracking Ethereum, XRP, and Solana, have seen growing capital inflows, indicating a shift in investor interest.
Bitcoin ETFs Struggle Amid Outflows
Bitcoin’s performance in the ETF market has been under pressure, as institutional investors pulled substantial capital. Grayscale’s GBTC fund recorded the largest outflows, with $44.03 million exiting. This was followed by Fidelity’s FBTC fund, which experienced a $39.44 million outflow. Despite these withdrawals, BlackRock’s IBIT fund helped soften the blow, bringing in $28.76 million in inflows on the same day.
However, the outflows suggest a shift in institutional sentiment towards Bitcoin-focused ETFs, as the cryptocurrency continues to face price volatility. Bitcoin’s price has fluctuated, making it difficult for some investors to stay confident in the asset class through ETFs alone.
Ethereum ETFs See Positive Momentum
In contrast to Bitcoin, Ethereum-focused ETFs experienced a surge in inflows. On December 8, Ethereum ETFs saw a net inflow of $35.5 million. BlackRock’s ETHA fund was the standout, attracting $23.7 million of that total. This influx reflects growing investor interest in Ethereum as a promising alternative to Bitcoin in the ETF space.
Ethereum’s rise in popularity among institutional investors could be tied to its ongoing upgrades and developments in the broader ecosystem. As Ethereum moves closer to full scalability and continues to see adoption in decentralized finance (DeFi) and other sectors, its appeal in the ETF market remains strong.
XRP and Solana ETFs Show Robust Capital Inflows
Altcoin ETFs have also been gaining traction in the market. Ripple’s XRP, in particular, has seen impressive institutional inflows, with over $900 million flowing into XRP spot ETFs since their launch last month. On December 8, XRP funds alone attracted $38.04 million, highlighting the growing institutional appetite for alternative crypto assets beyond Bitcoin and Ethereum.
Similarly, Solana, another major altcoin, is gaining traction in the ETF space. Fidelity’s FSOL fund recorded $1.18 million in net inflows on December 8, bringing the total capital raised by Solana ETFs to $640 million since their launch in late October. Solana’s rapid adoption and strong technical fundamentals are likely contributing to its success in the ETF market.
Outlook for the Crypto ETF Sector
Despite Bitcoin ETFs facing recent struggles, the broader crypto ETF sector remains optimistic. Experts believe that the popularity of altcoin-focused ETFs like XRP and Solana signals a diversification of investment strategies. As Bitwise Asset Management executive Katherine Dowling points out, crypto ETFs offer a convenient entry point for many investors to gain exposure to digital assets, and altcoin funds have “promising fundamentals” that could fuel further price growth.
Market analysts also view this shift in capital flows as a healthy rebalancing within the ETF market. The move away from Bitcoin-focused ETFs could represent a tactical shift by institutional investors, who are diversifying into promising altcoins while maintaining long-term confidence in Bitcoin as a store of value.
With the continuous growth of the ETF market and altcoin exposure, the trajectory for the next year appears positive, though volatility in the crypto market will likely remain a factor. As Bitcoin continues to mature as a regulated asset, the ETF market could provide deeper and more stable inflows in the coming years.
