Investors aren’t easing off the gas. Bitcoin and Ethereum ETFs just brought in over $1 billion in combined net inflows on a single day, their biggest haul in months. With crypto markets heating back up and institutional interest holding steady, Thursday’s surge is a strong signal that traditional investors aren’t sitting this rally out.
Bitcoin ETFs Carry the Weight
Let’s start with the heavy lifter. Bitcoin ETFs were responsible for the bulk of the action, pulling in just under $935 million in one day. Most of that came from one fund: BlackRock’s iShares Bitcoin Trust (IBIT), which brought in a massive $877 million on its own.
This puts IBIT’s total year-to-date inflows above $7.7 billion, making it one of the most popular ETFs in the country, crypto or otherwise. Fidelity’s FBTC and ARK’s ARKB chipped in as well, but IBIT clearly stole the spotlight.

This marks the seventh straight day of positive flows for Bitcoin ETFs. Since they launched in January, U.S.-based spot Bitcoin ETFs have pulled in over $44 billion combined. That’s a big number, and it’s growing steadily.

Ethereum Gets a Boost Too
Bitcoin may be leading the charge, but Ethereum isn’t being left behind. On the same day, Ethereum ETFs saw $110.5 million in inflows. That’s their best single-day total since February.
Grayscale’s ETHE fund led the way with just under $44 million, followed closely by Fidelity’s FETH, which brought in a similar amount. Bitwise’s ETHW also saw smaller but meaningful gains.

Altogether, Ethereum ETFs have now had five consecutive days of inflows. For the month of May, they’ve collected over $210 million so far. That momentum is notable, especially considering that ETH ETFs have had a slower start than their Bitcoin counterparts.
What’s Driving This Inflow?
A few things are happening at once. First, Bitcoin recently surged to new highs, brushing up against $110,000 earlier this week. That’s brought a fresh wave of attention to crypto markets, even among more cautious investors.

Second, inflation worries and an uncertain macro environment are pushing institutions to diversify. Many are now treating Bitcoin like digital gold, and ETFs give them an easy, regulated way to get exposure without having to deal with private keys or custody risk.
BlackRock’s IBIT, for example, has already become one of the most actively traded ETFs in the U.S. this year, a strong sign that crypto isn’t just a niche bet anymore.
Still Waiting on the SEC
Despite all the enthusiasm, there are still some hurdles. The SEC recently delayed a decision on whether to allow in-kind redemptions for Bitcoin and Ethereum ETFs. Right now, redemptions are done in cash. If in-kind redemptions are approved, institutions could swap shares directly for crypto, which could make the process cheaper and more tax-efficient.
The delay isn’t unexpected, but it’s a reminder that regulatory clarity is still a work in progress.
Looking Ahead
This billion-dollar day isn’t just a blip. It shows that crypto ETFs are becoming a serious part of the investment landscape. If current trends continue, we might look back at days like this as the point where traditional finance fully opened the door to crypto, and never looked back.
