BLOCKINSIDERLoadingCrypto ETF flows turned volatile this week as Bitcoin saw heavy month-end outflows while Ethereum stayed resilient with steady institutional inflows.
Crypto ETF investors had another volatile week between July 27 and 31, 2026. While Bitcoin ETFs saw mixed flows throughout the week, Ethereum funds continued to attract fresh institutional money despite overall market uncertainty.
BlockInsider breaks down the week's Bitcoin and Ethereum ETF activity, explaining how major market events shaped institutional investment decisions throughout the week.
The week began with improving market sentiment after tensions in the Middle East eased, reducing demand for safe-haven assets. Oil prices declined, while investors started moving capital into riskier assets, especially Ethereum.
Bitcoin quickly climbed above $65,562, but institutions remained cautious. U.S. spot Bitcoin ETFs recorded a net outflow of $11.6 million, led by BlackRock's IBIT with $8.8 million and Fidelity's FBTC with $2.8 million.
Meanwhile, Ethereum benefited from the shift in sentiment. Spot Ethereum ETFs attracted $11.7 million in net inflows, led by BlackRock's ETHA, showing institutions were adding exposure to ETH instead of Bitcoin.
On July 28, the crypto market turned completely cautious ahead of the U.S. Federal Reserve's interest rate decision.
As a result, Bitcoin fell to a low of $62,714, while spot Bitcoin ETFs recorded net outflows of $49.7 million, mainly due to BlackRock's IBIT with $54.8 million. The only positive inflow came from Grayscale's BTC fund, which added $5.1 million.
Ethereum continued to outperform. Along with growing interest following Morgan Stanley's new Ethereum and Solana institutional trusts, spot Ethereum ETFs recorded $9.4 million in net inflows.
The Federal Reserve kept interest rates unchanged, giving markets some relief after days of uncertainty. Bitcoin recovered toward $64,638 as investor confidence improved.
The change in sentiment was reflected in ETF flows. Spot Bitcoin ETFs attracted $32.1 million in net inflows, with BlackRock's IBIT adding $89.8 million. However, some investors took profits, resulting in outflows of $43.1 million from Fidelity's FBTC and $14.6 million from ARKB.
Ethereum ETFs moved in the opposite direction. Spot Ethereum ETFs recorded a $32.9 million net outflow.
Institutional demand picked up sharply on Thursday as large investors returned to Bitcoin ETFs. Although technology stocks remained under pressure after earnings, many institutions increased their crypto exposure.
Spot Bitcoin ETFs recorded one of the week's biggest inflows at $233.1 million, led by BlackRock's IBIT with $183.4 million, followed by Fidelity, Bitwise, ARKB, and several other funds that saw inflows.
Ethereum also remained positive. Spot Ethereum ETFs added $12.8 million, with BlackRock's ETHA leading the day's inflows.
The week ended with heavy selling as investors booked profits before the end of July. Weak quarterly earnings from Coinbase and Strategy, along with slower progress on U.S. crypto legislation, also weighed on market sentiment.
Bitcoin dropped below $63,000, while spot Bitcoin ETFs recorded a $265.4 million net outflow, led by BlackRock's IBIT which recorded an outflow of $122.7 million, followed by Fidelity's FBTC and Grayscale's GBTC.
Despite broader market weakness, spot Ethereum ETFs still recorded a $9 million net inflow, led by BlackRock's ETHB, suggesting institutions continued accumulating ETH even as Bitcoin faced strong selling pressure.
Looking at the previous week's flows, institutional investors became more cautious this week.
Last week, Bitcoin ETFs recorded a net inflow of $33.8 million, showing strong buying interest. This week, that trend reversed as Bitcoin ETFs ended with a net outflow of $61.5 million.
Most of the selling came on the last day of the month as investors booked profits. Ethereum performed better, recording small but steady inflows on most trading days.
