Bitcoin ETF Surge Drives Daily Volume to $7.5 Billion
Momentum isn’t just alive in crypto exchange-traded funds (ETFs), it’s surging. Bitcoin ETFs clocked a staggering $608.99 million in net inflows on Wednesday, May 21, notching their 6th consecutive day in the green and registering $7.64 billion in total value traded, levels last seen in February 2025.
Blackrock’s IBIT was once again the heavyweight, drawing $530.63 million and accounting for the lion’s share of the day’s inflows. Fidelity’s FBTC followed with $23.53 million, while Grayscale’s Bitcoin Mini Trust and Bitwise’s BITB added $22.14 million and $20.49 million, respectively.

Smaller but notable contributions came from Vaneck’s HODL ($6.09 million), ARK 21Shares’ ARKB ($4.29 million), and Valkyrie’s BRRR ($1.83 million). Remarkably, no outflows were reported across the 12 Bitcoin ETFs, signaling continued investor confidence. Total net assets rose to $129.02 billion.
Ether ETFs also kept pace, albeit with more modest movement. A net inflow of $587,130 was recorded, marking the 4th straight day of inflows. While Blackrock’s ETHA brought in $24.86 million, it was nearly offset by Fidelity’s FETH, which saw $24.28 million in outflows. Still, the balance tilted positive. Ether ETFs saw $657.66 million in trading volume, with net assets closing at $8.74 billion.
With both Bitcoin and Ether ETFs in extended inflow territory, institutional enthusiasm is proving anything but fleeting.
