New York Stock Exchange trading floor as crypto ETF inflows accelerate

$825 Million Hit Crypto ETFs in One Day—But the Strongest Signal Was Not Bitcoin

Wall Street poured more than $825 million into U.S. spot Bitcoin and Ether exchange-traded funds in a single session. The bigger signal, though, was buried beneath that headline number.

The money did not stop with Bitcoin.

According to Decrypt, U.S. spot Bitcoin ETFs collected $606.29 million on Thursday, August 20. That was their strongest daily intake since May 1 and their fourth positive session in a row.

Spot Ether ETFs added nearly $221 million, while XRP and Solana funds pulled in $13 million and $15 million, respectively.

BlackRock’s IBIT supplied $502.99 million of the Bitcoin total, while Fidelity, Bitwise, and ARK 21Shares all finished positive. VanEck’s HODL moved the other way with a $3.59 million outflow.

The same dataset showed that every listed crypto-asset ETF category attracted money during the session. That combination—heavy Bitcoin buying plus positive flows into Ether, XRP, and Solana—made Thursday broader than a one-coin surge.

That breadth matters because it separates this session from a simple Bitcoin chase. Investors were adding exposure across the biggest parts of the crypto market even after prices had already moved sharply higher.

The money broadened—but Bitcoin demand narrowed.

There was an important split inside the Bitcoin number. BlackRock’s iShares Bitcoin Trust, IBIT, captured $502.99 million of the $606.29 million total.

In other words, roughly 83 cents of every new dollar entering U.S. spot Bitcoin ETFs went into one fund.

Fidelity’s FBTC took in $64.74 million, Bitwise’s BITB added $26.4 million, and ARK 21Shares’ ARKB drew $12.2 million. VanEck’s HODL was the exception, posting a $3.59 million outflow.

That concentration is not automatically bearish. IBIT is the largest and most liquid product in the category, so it is a natural destination when institutional demand accelerates.

But it does show that the $606 million headline was not a uniform vote of confidence across every Bitcoin fund.

The four-day Bitcoin ETF inflow streak now totals about $1.61 billion. Cointelegraph reported that August inflows reached roughly $2.07 billion through Thursday, already making it the strongest month of 2026 with seven trading sessions still to go.

Cumulative net inflows into the U.S. Bitcoin products reached about $53.4 billion, while the Thursday session alone extended the category’s positive run to four consecutive trading days.

Ether funds also logged four straight positive sessions. Their weekly intake reached roughly $512.2 million, August inflows climbed to about $754.9 million, and total net assets rose to approximately $13.58 billion.

Thursday’s Ether figure was the largest across 203 trading sessions spanning 296 calendar days. The last bigger daily intake came on October 28, 2025, when the funds drew about $246 million.

Ether delivered the cleaner surprise.

Bitcoin still attracted the most dollars, but Ether produced the more revealing comparison. Its nearly $221 million intake was the category’s largest daily inflow since October 2025 and extended its own positive streak to four sessions.

The smaller funds also accelerated. XRP’s $13 million intake was more than five times the prior session’s $2.35 million, while Solana’s $15 million was more than seven times its previous $2.10 million.

Every listed crypto-asset ETF category finished the day with net inflows.

That is the detail worth watching. Bitcoin leadership is normal.

Simultaneous demand for Ether, XRP, and Solana is a stronger indication that investors are widening their risk appetite rather than making one defensive allocation to the largest coin.

Price confirmation arrived, but so did a warning.

Bitcoin traded near $77,000 Friday after briefly approaching $80,000 overnight. The rally also pushed it back above its 200-day moving average for the first time since November 2025.

The ETF data support the move, but they do not guarantee that it continues. Daily fund flows can reverse quickly, and the concentration in IBIT means investors should distinguish broad crypto demand from broad demand across Bitcoin products.

The next useful test is straightforward: can Bitcoin funds extend the streak without relying so heavily on one issuer, and can Ether, XRP, and Solana products keep attracting capital after the first burst of enthusiasm?

If both happen, this becomes more than a powerful Bitcoin rebound. It starts to look like regulated crypto demand is widening again.
