In a promising development for the cryptocurrency market, U.S.-based spot Bitcoin ETFs have recorded significant inflows over the past five days, amassing nearly $500 million. Data from SoSoValue indicates that as of September 25, the 12 spot Bitcoin ETFs collectively registered inflows of $105.84 million, marking the fifth consecutive day of positive net inflows. In total, these ETFs have attracted $496.56 million in the past week, signaling heightened interest from institutional investors.

Among the top-performing funds, BlackRock’s IBIT, the largest Bitcoin ETF, continues to lead with a substantial inflow of $98.9 million, bringing its total net inflows to a remarkable $21.2 billion. Meanwhile, Bitwise’s BITB attracted $2.1 million. However, some funds like Fidelity’s FBTC and ARK 21Shares’ ARKB experienced outflows, with $33.2 million and $47.4 million being withdrawn, respectively.

Despite these outflows, Bitcoin ETFs overall remain in a strong position, with total trading volume across the 12 funds amounting to $795.85 million on September 25. This volume, while lower than the $1.11 billion recorded the previous day, reflects steady investor participation. Since their launch, these ETFs have accumulated a total net inflow of $17.94 billion. At press time, Bitcoin was trading at $63,675.

Not only Bitcoin ETFs are benefiting from this positive trend. The U.S.-based spot Ethereum ETFs have also seen continued inflows, with net inflows of $43.23 million on September 25. This marks the second consecutive day of positive performance for Ether ETFs. Grayscale Bitcoin Mini Trust was the top beneficiary, attracting $26.6 million, followed by BlackRock’s ETHA and Fidelity’s FETH with inflows of $9.4 million and $6.4 million, respectively.

Despite the strong inflows, the total trading volume for Ether ETFs dropped from $180.42 million on the previous day to $124 million on September 25. Cumulatively, the spot Ether ETFs have seen net outflows amounting to $580.94 million since their launch. Nevertheless, Ethereum was trading positively at $2,613 at the time of writing.

This surge in ETF inflows, particularly into Bitcoin, suggests increasing institutional adoption and growing investor confidence in cryptocurrency as an asset class. Many industry analysts are pointing to these trends as indicators of a potentially bullish phase for both Bitcoin and Ether, even as other macroeconomic factors, such as Federal Reserve policies, continue to influence market sentiment.
