Despite a challenging start to Q2, U.S.-based Bitcoin exchange-traded funds (ETFs) have experienced five consecutive weeks of net capital inflow – a positive sign indicating persistent institutional interest in Bitcoin investments, even as inflows begin to moderate. Recent data from Farside Investors reveals a strong showing on May 16th, with spot Bitcoin ETFs attracting $260 million in a single session. This marks the third consecutive day of gains following temporary withdrawals earlier in the week that disrupted investor flows. Notably, BlackRock’s iShares Bitcoin Trust (IBIT) led the charge, absorbing nearly $130 million alone. Fidelity’s Wise Origin Bitcoin Fund (FBTC) and ARK and 21Shares’ jointly managed fund (ARKB) also saw inflows of roughly $68 million and $58 million respectively. Grayscale’s newest offering, the Bitcoin Mini Trust, added a modest $4.6 million to the total. Although overall inflow for the week remained positive, it was significantly lower than April’s peak, when ETFs posted over $3 billion in just five days. The last time U.S. Bitcoin ETFs crossed the $1 billion weekly mark was at the end of April, with an influx of $1.8 billion. These sustained yet tapering inflows suggest a shift from intense accumulation to cautious investment. The data suggests that while enthusiasm hasn’t vanished entirely, investors may be adjusting their strategies after several weeks of substantial Bitcoin purchases.
