Preliminary data shows that the United States spot Bitcoin exchange-traded funds (ETFs) had the second-best-ever joint net inflow day of $886.6 million.

Top Performers in Net Inflows

According to early data from Farside Investors, BlackRock’s iShares Bitcoin Trust (IBIT) ranked second with $274 million, while the Fidelity Wise Origin Bitcoin Fund (FBTC) received the highest inflow at $378.7 million.

With $138.7 million in net inflows, the ARK 21Shares Bitcoin ETF (ARKB) ranked third-best according to Farside statistics.

With a record $1.04 billion, it is the greatest net inflows the funds have seen since March 12. One day later, on March 13, Bitcoin reached an all-time high of $73,679.

Grayscale Bitcoin Trust and Market Reactions

Since it changed from a closed-end fund to a spot ETF in January, Farside data revealed that the Grayscale Bitcoin Trust (GBTC) witnessed a rare inflow day at $28.2 million, the sixth time it has received an inflow.

With its high management fee of 1.5% and reduced discount that saw many investors see a chance to escape, GBTC has experienced nearly $17.8 billion in net withdrawals.

Originally holding 620,000 BTC when the first Bitcoin ETFs debuted, Grayscale’s Bitcoin fund has dropped to 285,481 BTC, valued at $20.2 billion, per Apollo Bitcoin Tracker.

Industry Reactions and Market Impact

Responding to Bitcoin detractors on X who said the Bitcoin ETFs would find little demand, ETF Store president Nate Geraci shot back.

Geraci wrote: “I was advised some months ago that all of the ‘degen retail’ investors who wanted to buy had already done so, and there was nobody left. How would this be?”

Bloomberg ETF analyst Eric Balchunas wrote on X that it was “big-time flows all around today for The Ten,” the Bitcoin ETF bar Hashdex’s, which joined the market months after the others had started and has battled to see inflows.

With each issuer posting no flows for June 4, the Bitcoin ETFs from Invesco Galaxy, Franklin Templeton, WisdomTree, and Hashdex had no interest.

It comes as CoinGecko reports Bitcoin has rebounded 2.9% to $71,000 over the past 24 hours.
