US Bitcoin Spot ETFs See $378M Net Inflows, Grayscale GBTC Ends 78-Day Outflow Streak

·

The US bitcoin spot ETF market showed strong signs of recovery on Friday, March 3, 2025, with a total net inflow of $378.3 million—marking the end of seven consecutive days of outflows. This shift signals renewed investor confidence in digital asset exposure through regulated exchange-traded products.

According to preliminary data from Farside Investors, nine out of 11 actively traded bitcoin spot ETFs recorded positive inflows on the day, while the remaining two saw neutral flow activity. The reversal is particularly significant given the prolonged period of capital withdrawal that had dominated market sentiment in recent weeks.

Grayscale GBTC Turns the Tide After 78 Days

One of the most notable developments was Grayscale Bitcoin Trust (GBTC) recording its first net inflow since converting to a spot ETF in January 2025. The fund attracted $63 million in fresh capital, breaking a historic 78-day streak of continuous outflows—a trend that began shortly after its regulatory approval and conversion.

This turnaround suggests that investor perception around GBTC may be shifting. After months of outflows due to higher fees compared to competitors like BlackRock’s IBIT and Fidelity’s FBTC, the renewed interest could reflect strategic rebalancing by institutional investors or improved market positioning.

As of March 4, 2025, GBTC manages approximately 291,239 BTC, valued at around **$18.3 billion**, according to Grayscale’s official fund data. While this represents a 53% decline from its peak holdings of 619,220 BTC on January 11, it remains the largest bitcoin spot ETF by assets under management (AUM). BlackRock's IBIT follows in second place with roughly $16.9 billion in AUM.

Fidelity and Franklin Templeton Lead Strong Institutional Demand

Fidelity’s FBTC emerged as the top-performing ETF by inflow volume on Friday, drawing in approximately $102 million—the highest single-day amount among all funds. This reinforces Fidelity’s growing reputation as a trusted gateway for traditional finance (TradFi) investors entering the digital asset space.

Meanwhile, Franklin Templeton’s EZBC posted a record-breaking $60.9 million in net inflows—the largest daily increase since its launch—highlighting increasing diversification in investor preferences beyond just the largest players.

In contrast, BlackRock’s IBIT, despite its massive scale, saw a relatively modest inflow of $12.7 million on the day. This lower figure may reflect market saturation after rapid accumulation earlier in the year or a temporary pause as investors rotate into alternative offerings with different fee structures or tax efficiencies.

These movements underscore a maturing market where capital is no longer chasing only the biggest name but is being allocated based on value, strategy, and long-term sustainability.

Market Implications of Renewed Inflows

The return of net inflows across multiple issuers indicates several key shifts in the macro and micro landscape:

Moreover, the fact that even GBTC—long criticized for its premium structure and higher expense ratio—can attract inflows again suggests that liquidity dynamics and market depth are improving across the board.

What caused the sudden reversal in US bitcoin spot ETF flows?
