Blackrock And Fidelity Lead Bitcoin ETF Inflow Rally

Bitcoin ETFs Log $532M in a Third Straight Day of Gains

U.S. Bitcoin $BTC spot ETFs recorded $532 million in net inflows on May 4, according to data from SoSoValue — the third consecutive day of positive flows, suggesting that large investors continued to add exposure even as crypto markets remained volatile.

BlackRock's IBIT and Fidelity's FBTC drove the session. BlackRock's IBIT led with $335.46 million, followed by Fidelity's FBTC with $184.57 million. Together, the two products accounted for roughly $520 million of the total day's flows. Morgan Stanley's MSBT ETF added a modest $12.16 million, while other funds including Bitwise, Ark, Invesco, Franklin, Valkyrie, VanEck, WisdomTree, and Grayscale reported no net inflows for the day.

The May 4 session extended a run that began with a strong start to the month. On May 1 alone, U.S. spot Bitcoin ETFs recorded $629.8 million in inflows, with BlackRock contributing $284.4 million. That surge was notable because it came after Bitcoin ETFs had experienced a short three-day outflow streak — rather than signalling weakness, the market quickly reversed, with BlackRock and Fidelity consistently absorbing selling pressure from other funds.

The inflows also came alongside $BTC climbing above the $80,000 mark and briefly touching $81,000 for the first time in over three months. Fidelity's FBTC has now attracted $11.27 billion in total inflows, cementing its position as one of the leading competing products in the market.

Ethereum ETFs Also Draw Institutional Interest

U.S. Ethereum $ETH spot ETFs were not left out. The category posted $61.29 million in net inflows on the same day, with BlackRock's ETHA accounting for the majority at $54 million, according to SoSoValue data.

The dual-asset inflow day underscores a broader trend. The growth of Bitcoin ETFs, led by BlackRock's IBIT, reflects a shift toward regulated investment products, and steady institutional participation through ETFs suggests long-term viability of the category. By contrast, Solana and XRP ETFs recorded no inflows on the day, pointing to weak institutional interest outside Bitcoin and Ethereum.

Bloomberg ETF analyst Eric Balchunas has flagged the sustained strength of IBIT specifically, noting that the fund ranked eleventh in April flows with $2.3 billion — a strong number given it was the only ETF on the list with a negative year-to-date return.
