Bitcoin ETFs Pull $590M on BlackRock’s Second-Largest Day of Inflow

• Bitcoin ETFs command $109.3 billion in net assets, or 5.83% of BTC’s market cap.
• BlackRock’s IBIT holds $56.73 billion worth of Bitcoin.
• Ethereum ETFs hold $6.2 billion in net assets, representing 2.87% of ETH’s market cap.

U.S. spot Bitcoin (BTC) exchange-traded funds (ETFs) could be entering into a weeks-long run of inflows as funds garner over half a billion at the start of the week.

It was also the second-biggest day of inflows on record for BlackRock’s leading fund, whilst all other funds saw net outflows, or zero flows either way. Meanwhile, Ethereum (ETH) funds continue to lag.

Bitcoin ETFs

As per SoSoValue, Bitcoin ETFs recorded a sturdy $591.29 million in daily total net inflows on April 28, 2025, marking day six of a noticeably large inflow streak.

Since April 21, 2025, funds have pulled just over $3.59 billion in net inflows. Investors are slowly reversing the billions in exits between February and March 2025.

Taking the top spot by a long stretch is BlackRock iShares Bitcoin Trust (IBIT), which raked in a gigantic $970.93 million in net inflows, its second largest inflow since Nov. 7, 2025.

The leading fund has tallied $42.17 billion in cumulative net inflows and currently commands $53.88 billion in net assets.

Oddly, the rest of the flows are negative, starting with ARK 21Shares’ Bitcoin ETF (ARKB), which took the biggest hit, shedding $226.3 million in net outflows. ARKB has recorded $2.88 billion in cumulative net inflows and holds $4.77 billion in net assets.

It’s followed by Fidelity’s Wise Origin Bitcoin Fund (FBTC) ,which posted $86.87 million in net outflows. FBTC is the second-largest fund by cumulative net inflows and net assets with $11.77 billion and $18.94 billion, respectively.

Grayscale’s Bitcoin Trust (GBTC) saw a further $42.66 million exit its fund. It’s the worst-performing fund by far, as it’s the only fund with negative flows. GBTC’s cumulative net outflows have now reached $22.73 billion, and its net assets have shrunk by more than half to $18.07 billion.

Smaller losses were incurred by the Bitwise Bitcoin ETF (BITB), which tallied a humble $21.13 million in net outflows. The fund has notched $2.07 billion in net inflows and currently holds $3.67 billion in Bitcoin.

Finally, VanEck’s Bitcoin ETF (HODL) lost a very modest $2.68 million in net outflows. Its cumulative net inflows now stand at $864.94 million, with net assets now at $1.37 billion.

Ethereum ETFs

Ethereum funds are drawing some inspiration from the momentum behind BTC ETFs, and pulled a modest $64.12 million in daily total net inflows on April 28, 2025.

Once again leading the charge, BlackRock’s iShares Ethereum Trust (ETHA) bagged $67.47 million in daily net inflows. Its cumulative net inflows now stand at $4.18 billion, and net assets at $2.25 billion, ranking it first amongst competitors.

Just one fund saw outflows, the Bitwise Ethereum ETF (ETHW), which posted $3.35 million in exits. The fund’s cumulative net inflows have now dropped to $318.03 million, and net assets to $168.3 million, ranking it fourth and fifth, respectively.
