Bitcoin ETF has seen a drop in weekly inflows as Bitcoin’s price has fallen below the $104,000 level.
According to SoSoValue data updated on May 16, 2025, weekly inflows to Bitcoin ETFs dropped to $603.74 million. This is a 35% decrease from the previous week’s $934.17 million.
Weekly Bitcoin ETF inflows drop 35%
Bitcoin spot ETFs experienced their third consecutive week of declining inflows. The week through May 16, 2025, registered $603.74 million in new money. That represents 35% less than last week’s $934.17 million and follows the downward trend from the April 25 high at $3.06 billion.
The weekly trend of inflows has been weakening steadily since late April, and the inflows have been weakening progressively: $3.06 billion (Apr 25), $1.81 billion (May 2), $934.17 million (May 9), and now $603.74 million (May 16). Although weakening, the past three months are much better compared to the first half of the year.
Weekly volume traded was $14.38 billion for the week ended May 16, higher than last week’s $11.93 billion but lower than the $18.76 billion for the week ended April 25. May 16 daily data brings more upbeat momentum with $260.27 million in net inflows and $2.70 billion in daily trading volume. This daily data shows weekly inflows have declined, but investor appetite is still there on a daily basis.
ETF provider performance shows concentration of inflows
A breakdown of Bitcoin ETF flows by issuer indicates that inflows remain dominated by a few top issuers. BlackRock’s IBIT remains on top with $129.73 million of daily inflows, as data from May 16 indicates. It accounted for nearly half the day’s total. Fidelity’s FBTC followed with $67.95 million and Ark’s ARKB with $57.98 million.
BlackRock’s IBIT remains in the lead with a net asset value of $65.72 billion. That is more than 53% of the combined assets of all Bitcoin ETFs. IBIT has total inflows of $45.55 billion from inception. Fidelity’s FBTC is at number two, with assets of $20.56 billion and total inflows of $11.59 billion.
Grayscale’s GBTC, while showing a slight positive price momentum of 0.05% on May 16, still has zero daily inflows. Its net total outflows have now increased to $22.99 billion. It still retains the third-highest asset size with $19.55 billion in net total assets.
Some smaller ETFs did not experience any inflows on May 16 despite the positive price action. They include Bitwise’s BITB (+0.29%), VanEck’s HODL (+0.24%), and Valkyrie’s BRRR (+0.28%). There was one, Hashdex’s DEFI, which experienced negative price action at -0.40% for the day.
Bitcoin price drop is synchronized with changing investor trends
Bitcoin’s price action below the $104,000 level appears to dictate investor sentiment in ETF markets. Bitcoin’s price volatility shows investors are becoming jittery as the market moves away from recent highs.
In spite of this volatility, overall net assets in all the Bitcoin ETFs have kept increasing. It stood at $122.67 billion as of May 16. That is above $121.23 billion on May 9 and $113.15 billion on May 2. The increase in overall assets in spite of declining inflows implies that new capital coming into the market has softened.
Bitcoin market capitalization in ETFs has also increased to 5.95% from earlier readings. Weekly inflows, while lower, remain positive for most of the large ETF providers. The week of March and early April was an exception, where Bitcoin ETFs experienced high outflows, for instance, -$713.30 million for the April 11 week and -$838.27 million for the March 14 week.
