NYDIG Suggests $1.3B IBIT Sale Was Whale Exiting Directional Trade
NYDIG says a $1.26 billion IBIT block trade looked like a large holder paying up to exit fast, not a basis-trade unwind.

NYDIG’s Greg Cipolaro argued that a huge BlackRock IBIT sale on a dark pool looked like a sophisticated trader choosing speed over price. The note pointed to ETF outflows, weak market sentiment, and a large execution discount as signs of a deliberate exit.
A very big bitcoin fund owner wanted out fast. Instead of selling slowly and maybe getting a better price later, that person paid extra to leave right away.
Think of it like a person selling a huge pile of concert tickets. If they care most about speed, they may accept less money just to finish the sale now.
NYDIG thinks this was not a normal cleanup trade. It looked more like someone who no longer wanted a big bet tied to bitcoin and chose the quickest exit.
Analysis
What happened
NYDIG’s head of research, Greg Cipolaro, said a $1.26 billion sale of BlackRock’s iShares Bitcoin Trust looked more like a whale leaving a concentrated directional bet than a routine basis-trade unwind. The trade involved 29.2 million IBIT shares sold on a dark pool, which is a private venue used by institutions for large transactions.
Why NYDIG read it that way
Cipolaro pointed to the seller accepting a price about $1.01 below the market level of $44.17. That meant giving up roughly $29.5 million to get the position off the books immediately. In NYDIG’s view, that kind of urgency is more consistent with a holder trying to exit quickly than with a normal portfolio rebalance.
Market backdrop
The timing mattered. U.S.-listed bitcoin ETFs had already logged 11 straight trading days of net outflows, and the same day as the IBIT block trade saw another $333.6 million leave the funds, according to Farside Investors. More than $2.9 billion had flowed out since May 14, the last day of net inflows across multiple funds.
Cipolaro said the public data cannot prove whether the seller was under pressure from redemptions, balance-sheet constraints, or simply changing conviction. Still, he said the combination of weak technical conditions, ongoing ETF outflows, and the willingness to pay up for speed fit discretionary liquidation more than a tidy unwind. Bitcoin fell 2.8% on the day after the trade, while Bloomberg ETF analyst Eric Balchunas said the market handled the sale better than many expected.
