Between September 29 and October 3, 2025, Bitcoin spot ETFs attracted over $3.24 billion in new investments, marking the second-largest weekly inflow in the history of these funds. The largest single-day inflow occurred on October 3, exceeding $985 million, while the smallest inflow during the week was around $430 million on September 30, according to SoSo Value.
During the same period, Ethereum ETFs also performed strongly, drawing roughly $1.3 billion — the highest weekly inflow since mid-August. Their peak single-day inflow was $547 million on September 30, with the lowest at $80.79 million on October 1.
The surge in ETF investments coincided with a notable rise in cryptocurrency prices. Bitcoin climbed more than 10% during the week, reaching a new all-time high above $125,000 on October 5.
The latest figures underscore the growing institutional interest in crypto ETFs, highlighting their role as a bridge between traditional finance and the digital asset market. Both Bitcoin and Ethereum ETFs have become increasingly popular as investors seek regulated, transparent exposure to major cryptocurrencies.
Analysts note that such inflows can positively influence market sentiment, contributing to price rallies and attracting further institutional and retail participation.
