U.S. spot Bitcoin exchange-traded funds (ETFs) experienced a significant influx of capital on Thursday, drawing a net $608.3 million. This substantial intake elevated the total net inflows for the week to more than $1.6 billion.

The strong performance on Thursday marked the fourth consecutive session of positive net flows for Bitcoin funds. Data from SoSoValue indicates that the streak began with $297.6 million in net inflows on Monday, followed by $189.3 million on Tuesday and $517.2 million on Wednesday.

This figure surpasses the previous monthly high for 2026, which was set in April at $1.97 billion. The cumulative net inflows for these Bitcoin products have now reached a total of $53.4 billion.

These substantial inflows have coincided with a sustained rally in the cryptocurrency markets.

During the same period, Ether appreciated by 4.6%, trading at approximately $2,357.

In a parallel development, spot Ether ETFs also saw a notable surge in investor interest.
