Analysts linked Tuesday’s Bitcoin slide to a huge private sale of BlackRock’s IBIT that landed just before the market turned lower. The article also points to eight straight days of ETF outflows and weaker institutional demand.
A huge investor sold a giant pile of Bitcoin fund shares very quickly, but did it in a quiet private market. Right after that, Bitcoin’s price dipped, like a seesaw tipping when one heavy person gets off.
The story says this was not just one small wobble. Bitcoin funds have been losing money for several days in a row, which means some big investors may be stepping back.
Think of it like a popular toy store where a few giant shoppers suddenly return lots of toys. Other people see that and worry the toy is losing popularity, so they stop buying as much too.
Analysis
ETF flow pressure
Cointelegraph reports that an unknown trader sold 29.2 million shares of BlackRock’s iShares Bitcoin Trust ETF, or IBIT, on Tuesday at 2:30 p.m. UTC through a dark pool, a private venue often used for very large trades. The trade was valued at about $1.3 billion and coincided with a fast drop in Bitcoin’s price.
TradingView data cited in the article shows BTC falling 1.5% from $77,875 to $76,720 in the 10 minutes after the sale, then sliding further to a 24-hour low of $75,600 roughly 12 hours later. Galaxy Digital’s Alex Thorn said on X that it was the largest dark-pool trade he had seen. Bloomberg ETF analyst Eric Balchunas added that the IBIT sale was far larger than any other sell order in that fund on Tuesday.
Broader institutional signal
The piece frames the move as part of a wider weakness in Bitcoin ETF demand. US spot Bitcoin ETFs have now seen eight straight trading days of net outflows, including $333.6 million on Tuesday and $192.4 million from IBIT alone. Since May 14, more than $2 billion has reportedly left the funds.
Cointelegraph also notes that large institutions have trimmed exposure: Jane Street cut its Bitcoin ETF holdings by about 70% in the first quarter, while Goldman Sachs reduced its position by 10%. The article’s broader point is that Bitcoin is trading more like a macro asset now, with ETF flows and institutional positioning helping steer short-term price action.
