US-listed spot Bitcoin and Ethereum exchange-traded funds (ETFs) have reignited investor enthusiasm, pulling in more than $4.5 billion in net inflows last week.
The strong reversal ended a brief period of outflows and set the tone for October — a month traders often call “Uptober” for its history of bullish crypto performance.

Bitcoin and Ethereum ETFs Pull In $4.5 Billion
Data from SoSo Value shows Bitcoin ETFs brought in roughly $3.2 billion in net inflows, marking their second-largest weekly total on record, just behind November 2024’s $3.37 billion peak.
During the trading period, ETF volumes surged to about $26 billion. The sharp increase signaled stronger investor participation and renewed confidence that an accumulation phase may be underway.
BlackRock’s iShares Bitcoin Trust (IBIT) dominated inflows with $1.78 billion, followed by Fidelity’s FBTC at $692 million. Ark 21Shares added $254 million, while Bitwise captured another $212 million.
The collective surge reflects growing institutional conviction and renewed retail interest in gaining Bitcoin exposure through regulated investment products.
Meanwhile, Ethereum ETFs mirrored this momentum, attracting $1.29 billion in inflows and generating nearly $10 billion in weekly trading volume.

BlackRock’s ETHA fund led with $687 million in inflows, followed by Fidelity’s $305 million. Grayscale recorded $175 million, while Bitwise added $83 million.
Together, these figures indicate that investors are positioning for a broader market recovery rather than focusing on a single asset.
Institutional Demand Reignites Crypto Rally
The synchronized inflows across both Bitcoin and Ethereum ETFs made last week one of the busiest trading periods in recent memory.
This pattern suggests institutional portfolios are rotating back into digital assets, seeking to capture early upside potential as macro sentiment stabilizes.
That renewed optimism helped propel Bitcoin to a fresh all-time high above $125,000. It reinforced the belief that ETF-driven demand is doing more than fueling short-term speculation and may be establishing a base for a new market cycle.
Crypto research firm 10x Research noted that the scale of these inflows is unprecedented. It added that subtle shifts in institutional allocation strategies point to deeper structural support than in previous rallies.
“Behind the scenes, billions of dollars in ETF inflows and a quiet shift in institutional behavior suggest that this breakout may have deeper roots. Even regulators are adding fuel to the fire, with new tax guidance that caught corporate treasuries off guard,” it added.
