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 Tuesday, 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 Tuesday, 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.

XRP (XRP) stood out with $4.64 million in inflows, the first gains since March 4. The ETFs saw $56.8 million in outflows in the period from March 5-16.

Despite $33.5 million in outflows so far in March, XRP ETFs remain in the green year-to-date, supported by $73.7 million in inflows during January and February.
Solana leads all crypto ETFs year-to-date with $223 million in net inflows.
