BlackRock's Bitcoin ETF bleeds $405.3M in a day, its worst exit in four months

BlackRock's spot Bitcoin ETF lost $405.3M to outflows on Nov. 2, Cointelegraph reported. It's the largest single-day exit the fund has logged in more than four months. Money didn't just trickle out — it left in a lump.

The fund, the iShares Bitcoin Trust (ticker IBIT), has been the heavyweight of the U.S. spot Bitcoin ETF lineup since the category debuted in January 2024. Sitting at the top of that pile means its flow numbers get read as a temperature check on how big-money investors feel about bitcoin exposure.

What makes the Nov. 2 print stand out is the gap. Four-plus months without a daily drawdown that large means this wasn't routine churn — it's the kind of number that gets flagged the moment it hits. Cointelegraph's report didn't say what drove the exit, and no cause was given.

Now the question is whether this is a one-day blip or the front edge of something bigger. The next round of flow reports will tell the story, and everyone watching the ETF complex will be staring at BlackRock's number first.
