Bitcoin ETFs notch $2.4 billion in eight-day inflow streak; Ethereum ETFs’ catch-up phase appears to stall, analyst says

U.S. spot Bitcoin exchange-traded funds' net inflow streak extended into an eighth day on Wednesday, adding $389.5 million to a total of $2.4 billion for the period, according to data compiled by The Block.

BlackRock's IBIT continues to dominate over the other Bitcoin funds, attracting $278.9 million in net inflows on Wednesday alone, followed by Fidelity's FBTC with $104.4 million. Bitwise's BITB, Grayscale's BTC mini product, and Hashdex's DEFI brought in $11.3 million, $10.1 million, and $1.2 million, respectively. Grayscale's higher-fee converted GBTC fund experienced the only net outflows of the day, at $16.4 million, while the other ETFs registered zero flows.

IBIT also leads the eight-day streak, accounting for $2.3 billion or 96% of the net inflows. 

"8 straight days of inflows into spot Bitcoin ETFs," The ETF Store President Nate Geraci said on X. "Category has now taken in nearly $11.5 billion in 2025. Year two. Still 'no demand.'"

The U.S. spot Bitcoin ETFs have picked up $46.9 billion worth of cumulative net inflows since their debut in January 2024, with nearly $125 billion in assets now under management amid the concurrent price rise, per The Block's Bitcoin ETF Tracker page.

Meanwhile, U.S. spot Ethereum ETFs attracted net inflows of $19.1 million on Wednesday, again led by $15.1 million into BlackRock's ETHA fund. Last week, the Ethereum ETFs' heightened 19-day , $1.4 billion record net inflow streak came to an end, and the pace of flows has declined since. Despite more volatile flows, the Bitcoin ETFs attracted over $3.8 billion during the same 19-day period. Total net inflows for the Ethereum funds, which launched later in July 2024, currently stand at $3.9 billion.

"The data suggests institutions remain constructive on crypto's medium-term upside, but Ethereum's catch-up phase appears to be over," BRN Lead Research Analyst Valentin Fournier told The Block. "Despite the increase in institutional flows, momentum remains soft, weighed down by geopolitical concerns and a lack of catalysts."

Hawkish FOMC and geopolitical factors weigh on markets

Bitcoin is currently trading for $104,810, according to The Block's BTC price page , down 0.3% over the last 24 hours and 2.5% during the past week. Ethereum has fallen 8.3% to $2,527 over the same period as macro factors continue to weigh on market sentiment despite the positive ETF flows.

The Federal Open Market Committee left U.S. interest rates unchanged on Wednesday as expected, but the tone of the statement and follow-up comments was notably hawkish, Fournier said. "Bitcoin continues to hold above $100K, but struggles to break resistance, and looks increasingly likely to retest the $102K support unless momentum returns," he added. "With macroeconomic uncertainty elevated and no short-term catalyst on the horizon, we're staying cautious. The recovery in ETF inflows offers some reassurance, but price action remains fragile."

However, 21Shares Crypto Investment Specialist David Hernandez took a more positive stance. "As confidence in a perfectly engineered 'soft landing' wanes, and as global financial currents diverge, bitcoin's fundamental properties — its scarcity, decentralization, and neutrality — make it an increasingly relevant and compelling asset for investors navigating an uncertain future," Hernandez told The Block. "Bitcoin has firmly cemented itself above $100,000, and its resilience amid geopolitical shocks demonstrates its widespread adoption and developing investment case."
