Bitcoin ETF inflow streak nears October run, but totals still lag

US spot Bitcoin exchange-traded funds (ETFs) extended their inflow streak to seven consecutive days, marking the longest run since October 2025.

Spot Bitcoin (BTC) ETFs added $199.4 million on Monday, bringing their seven-day streak to around $1.2 billion, according to data from SoSoValue. The latest inflows suggest continued institutional interest, though total inflows remain far below the roughly $6 billion seen during the October 2025 run.

Total trading volumes fell to $2.6 billion on Monday, while total assets under management in Bitcoin ETFs climbed to $96.7 billion. Net year-to-date flows remain negative, following $1.8 billion in cumulative monthly outflows and $1.7 billion in cumulative inflows.

The ETF rebound has coincided with broader strength in crypto investment products, which drew about $2.7 billion over three straight weeks, lifting year-to-date inflows to roughly $1.2 billion, according to CoinShares.
