In a significant development for cryptocurrency investments, US-based spot Bitcoin and Ether exchange-traded funds (ETFs) kicked off 2026 with a remarkable performance, achieving combined net inflows of approximately $646 million on the very first trading day. This surge occurred despite the prevailing mixed sentiment in the broader cryptocurrency market.
On Friday, spot Bitcoin ETFs recorded net inflows of $471.3 million, while spot Ether ETFs contributed an additional $174.5 million. According to data compiled by Farside, these figures brought total inflows across the two types of ETFs to an impressive $645.8 million. Notably, this marked the largest net inflow for US spot Bitcoin ETFs in 35 trading days, since November 11, when the collective inflows reached $524 million in a single day. On the other hand, spot Ether ETFs also saw their highest single-day inflow in 15 days, marking their largest since December 9, when $177.7 million was recorded.
The strong inflow figures come in the wake of a challenging December for crypto ETFs, a month marked by a general market decline. Many participants in the cryptocurrency space view ETF inflows as a barometer of mainstream investor sentiment toward the asset class and a potential short-term price direction indicator. Historically, rising flows into ETFs often suggest growing investor confidence, while persistent outflows may indicate caution.
Recent trends reflect this cautionary sentiment. Over the past month, spot prices for both Bitcoin and Ether have fallen by approximately 1.56% and 1.39%, respectively. This downtrend coincides with a broader bearish market phase that started shortly after Bitcoin reached an all-time high of $125,100 on October 5. This peak was followed by a notable liquidation event on October 10, valued at $19 billion, which has contributed to a more cautious atmosphere among market participants. This mounting apprehension is echoed by the Crypto Fear & Greed Index, which has remained in the “Extreme Fear” zone since early November, recently registering a score of 25.
Despite the current sentiment, some industry executives express optimism about future trends. The Chief Marketing Officer of Tonso, known as “Wal,” shared insights on social media, suggesting that institutional investors are returning to the market. On Friday, he remarked, “spot Bitcoin ETFs are back,” noting that many institutional investors had sold off Bitcoin in the fourth quarter of 2025 for tax loss harvesting. He asserted that these investors are now gearing up to re-enter the market, indicating that this resurgence might just be the beginning of a new bullish phase.
In 2025, US investors demonstrated considerable engagement with cryptocurrency ETFs, pouring in excess of $31.77 billion into these investment vehicles. Among these, spot Bitcoin ETFs captured the majority of interest, amassing $21.4 billion in net inflows. However, this represented a decline from the $35.2 billion net inflows that were recorded in 2024.
As the cryptocurrency landscape evolves, the actions of institutional investors and the performance of ETFs will continue to be closely monitored for indications of shifts in market sentiment and price dynamics.
