US Bitcoin ETFs See $1.2 Billion Inflows, Still Lag Behind 2025 Peak
By John Nada·Mar 18, 2026·4 min read
US spot Bitcoin ETFs saw $1.2 billion in inflows over a week, marking a positive trend despite lower totals compared to October 2025. Institutional interest persists in the crypto ETF space.
US spot Bitcoin exchange-traded funds (ETFs) extended their inflow streak to seven consecutive days, totaling approximately $1.2 billion, according to data from SoSoValue. This marks the longest inflow run since October 2025, although the current figures remain significantly lower than the $6 billion seen during that month. The latest inflows suggest sustained institutional interest in Bitcoin ETFs, despite total trading volumes falling to $2.6 billion on Monday.
On March 13, spot Bitcoin (BTC) ETFs added $199.4 million, which contributed to the impressive seven-day inflow streak. This positive trend in Bitcoin ETFs contrasts sharply with the ongoing challenges in the broader market, where total assets under management in Bitcoin ETFs have risen to $96.7 billion. However, net year-to-date flows still show a negative trajectory, following $1.8 billion in cumulative monthly outflows against $1.7 billion in cumulative inflows. This mixed performance underscores a complex and evolving landscape for Bitcoin ETFs, highlighting the volatility and unpredictable nature of crypto investments.
The recent rebound in ETF inflows aligns with broader trends in crypto investment products. According to CoinShares, these products collectively attracted about $2.7 billion over a three-week period, bolstering year-to-date inflows to approximately $1.2 billion. This resurgence indicates that while Bitcoin ETFs face their challenges, the overall crypto investment environment may be stirring back to life, driven by renewed interest from institutional investors.
In addition to Bitcoin ETFs, other altcoin ETFs also experienced notable inflows. Ether (ETH) ETFs saw inflows of $138.3 million, marking the largest influx since March 4. Similarly, Solana (SOL) displayed a positive trend with $17.8 million in inflows, also the biggest since early March. These movements suggest that investor sentiment may be shifting favorably towards altcoins, potentially as a diversification strategy amid Bitcoin's fluctuating performance.
XRP ETFs, which had been under pressure in recent weeks, posted their first gains after an eight-day losing streak, receiving $4.64 million in inflows. This comes despite a challenging start to March, where XRP ETFs faced $33.5 million in outflows. Interestingly, year-to-date, XRP ETFs remain in the green, buoyed by $73.7 million in inflows during January and February. This resilience could indicate that investors are still finding value in XRP, particularly as regulatory clarity continues to evolve.
The performance of Solana stands out notably, leading all crypto ETFs year-to-date with a remarkable $223 million in net inflows. This trend reflects a growing acceptance and interest in Solana as a viable alternative to Bitcoin and Ethereum, possibly driven by its technological advancements and community support.
However, the situation for Ether ETFs remains concerning, with $364.5 million in year-to-date outflows. This follows $358.5 million in inflows in March, juxtaposed against a staggering $723 million in outflows during the first two months of the year. The volatility faced by Ether ETFs may highlight the challenges of maintaining investor confidence amid market fluctuations and competitive pressures from newer cryptocurrencies.
The mixed performance across the crypto ETF landscape provides a window into the current state of institutional investment in digital assets. While Bitcoin remains a key player, the significant inflows into altcoin ETFs suggest that investors are increasingly willing to explore beyond traditional options. This trend is indicative of a more diversified approach, as institutional investors look to capitalize on emerging opportunities within the crypto space.
Additionally, as the market evolves, the implications of these trends suggest a complex interplay between investor sentiment, regulatory developments, and technological advancements. The sustained interest in Bitcoin ETFs indicates that institutional players are still keen on maintaining a presence in the market, even as they navigate the inherent risks associated with cryptocurrency investments.
The ongoing inflow streak for Bitcoin ETFs, albeit at lower levels than seen in previous peaks, demonstrates that there is still appetite for these investment products. As institutional strategies adapt to market conditions, the potential for future inflows could continue to shift, reflecting broader trends in the crypto ecosystem. The next few months will be critical in determining whether the current uptick in inflows can be sustained and whether it will translate into long-term growth for Bitcoin and other altcoin ETFs.
