U.S. spot Bitcoin ETFs attracted over $1 billion in net inflows this week.

This marks the first time weekly inflows crossed the $1 billion threshold since January. BlackRock’s iShares Bitcoin Trust (IBIT) captured the majority of the new capital.

IBIT drew approximately $721.5 million over the last three trading days. The fund recorded $134.6 million in inflows on Wednesday while some competitors saw outflows.

Bitcoin currently trades above the $81,000 level. The surge signals robust institutional interest in regulated crypto products.
