NYDIG reveals: A whale used $29.5 million to exchange for the “fastest Bitcoin sell-off”: The truth behind the 1.3 billion IBIT dark pool liquidity

NYDIG Research Director Greg Cipolaro pointed out that last week's $1.3 billion IBIT dark pool trade shows a whale willing to pay $29.5 million in discount for immediate exit, reflecting active liquidation rather than passive investor outflows.

NYDIG research head Greg Cipolaro, in a research report, noted that the $1.3 billion BlackRock IBIT dark pool sell order last week was very likely from a large directional holder eager to exit concentrated positions. This trader was willing to forgo a $29.5 million discount for immediate execution, highlighting urgency through private trading platforms.

Why are whales willing to "spend money to buy speed"?

According to Cipolaro’s Friday memo, multiple indicators point to "large directional holders exiting concentrated positions," rather than unwinding basis trade positions. The seller accepted a price of $44.16 (market price $44.17), below market value, indicating a near $29.5 million premium sacrificed for "immediate execution."

Cipolaro states in the report:

"While the trading details themselves can't answer this question, they do show that at least one mature holder is willing to pay about $29.5 million to immediately eliminate a $1.3 billion Bitcoin-related position."

He added that the key unresolved question is whether the seller is responding to specific financial constraints or expressing a broader investment view. He speculates it could be forced selling triggered by redemptions, or an effort to reduce risks associated with multi-day exits. However, technical weakness, ongoing ETF fund outflows, and willingness to pay large execution premiums better align with "voluntary liquidation" rather than investor outflows or portfolio rebalancing.

Background of continuous Bitcoin ETF fund outflows

According to Farside Investors, US-listed Bitcoin ETFs have experienced net outflows for 11 consecutive trading days, with $334 million leaving on the same day. Since the last significant inflow on May 14, over $2.9 billion has been withdrawn from these ETFs.

US Bitcoin ETFs face severe capital outflow pressure, reflecting a shift in institutional investors’ stance toward Bitcoin holdings.

Market sentiment-wise, the Crypto Fear & Greed Index fell to 29/100 on Monday, in the "fear" zone. The overall mood in May also leaned toward fear.

Market impact analysis of dark pool trading

Large trades typically influence market sentiment, but Bitcoin only dropped 2.8% after this trade. Bloomberg ETF analyst Eric Balchunas noted that the market absorbed this significant sell pressure. This may reflect the nature of dark pool trading, conducted via private platforms to avoid excessive impact on public markets.

NYDIG’s research indicates that such large dark pool operations reflect institutional investors actively adjusting their Bitcoin positions, possibly related to macroeconomic changes, liquidity expectations, or portfolio rebalancing. The proliferation of dark pools allows large traders to flexibly adjust holdings without alerting the public market.

Market observers believe dark pool data can serve as a "leading indicator" for institutional investors, helping to gauge the true buying and selling pressure from whales outside the public eye.
