Bitcoin, Ethereum ETFs Log Record $1 B Daily Inflows

In an unprecedented milestone, U.S.-listed Bitcoin and Ethereum ETFs collectively recorded $1 billion in net inflows within a single trading day on May 24. This surge eclipses the previous high-water mark of $750 million set in March and signals growing institutional confidence in crypto-based investment vehicles.

ETF landscape

Since their launches earlier this year, Bitcoin ETFs have seen rapid adoption. BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) currently manage a combined $9.2 billion in assets under management. Ethereum ETFs, introduced in late April, have drawn $3.7 billion across products such as VanEck’s Ethereum Strategy ETF (EFUT) and Franklin’s Ether ETF (ETHX).

According to data from CoinShares, total AUM across all U.S. crypto ETFs stands at $14.5 billion—nearly quadruple the level seen at the start of Q2. “These inflows underscore a major shift: crypto is maturing into a mainstream asset class,” said ETF strategist Amanda White of Horizon Financial.

Daily inflow details

On May 24 alone, Bitcoin-focused vehicles saw combined inflows of $720 million, while their Ethereum counterparts attracted $280 million. Notably, IBIT led Bitcoin ETFs with $340 million, followed by FBTC at $220 million. In the Ethereum space, EFUT accounted for $160 million and ETHX $95 million.

Smaller issuers also participated: VanEck’s Broad Digital Assets ETF (BDAT) drew $45 million after adding selective Ethereum exposure, demonstrating cross-market interest among diversified investors.

Bitcoin vs. Ethereum

Performance comparison

While Bitcoin ETFs captured the lion’s share of flows, Ethereum’s younger cohort is gaining ground. Over the past week, spot Bitcoin rallied 3.2% to $111,800, whereas Ethereum climbed 4.7% to $3,960—suggesting that investors are embracing ETH’s smart-contract narrative alongside Bitcoin’s digital-gold thesis.

Correlation dynamics

Historically, Bitcoin and Ethereum have exhibited an 0.85 correlation over 30-day windows. However, inflow patterns show a slight decoupling: ETH ETFs saw a relatively higher percentage gain of AUM (8.2% daily) versus Bitcoin’s 5.6%. “This reflects growing appetite for programmable-money use cases,” explained crypto strategist Elena Fields at Digital Asset Insights.

Market implications

The record inflows add fresh fuel to an already tight supply backdrop. On-chain data shows net Bitcoin issuance at all-time lows—only 900 new BTC entering exchanges daily. With institutional vehicles mopping up supply, prices could face upward pressure.

Meanwhile, Ethereum’s issuance model shifts following the Shanghai upgrade, which unlocked 4.1 million staked ETH. Yet, the combination of staking churn and ETF demand has kept net float constrained. “ETF flows are becoming a key driver of price discovery,” said on-chain expert Jake Smith of Chainalysis.

Looking ahead

Investors will be watching next week’s CPI report and Fed minutes for hints on macro headwinds. If inflation cools and rate-cut expectations rise, crypto ETFs could see another leg of inflows. Analysts at Bloomberg Intelligence peg a 60% chance of ETFs attracting a further $500 million daily by June’s end.

Moreover, the SEC’s pending verdict on spot Ethereum ETF applications could unlock billions more. A green light for additional ETH products would broaden investor choice and potentially replicate the Bitcoin ETF success story.
