Key Points
On Tuesday, May 27, 2023, at 2:30 PM UTC, an institutional participant sold 29.2 million shares of IBIT through BlackRock's iShares Bitcoin Trust ETF, totaling $1.3 billion. This transaction was executed via a dark pool, which allows large investors to complete substantial orders without revealing their intentions.
The market reacted swiftly. According to TradingView data, Bitcoin dropped 1.5% within just ten minutes of the trade, sliding from $77,875 to $76,720. Subsequently, the digital asset continued to decline, reaching a 24-hour low of $75,600 approximately 12 hours after the trade, marking a total daily drop of 2.8%.

Alex Thorn, head of research at Galaxy Digital, described this transaction as the largest dark pool Bitcoin ETF trade he has ever seen. Bloomberg ETF expert Eric Balchunas noted that the size of this sell order exceeded the second-largest IBIT trade of the day by more than 22 times.
Cryptocurrency analyst Daan Crypto Trades shared his thoughts on social platform X: “This trade is a clear retest of the April 2025 low, and the rebound has performed well so far. However, the key level for continued upward movement remains in the low $80K range. If it falls below $74K, I believe the bears will regain control of the market.” His analysis highlights market participants' focus on critical price ranges.
Continued Outflow of ETF Capital
The U.S. spot Bitcoin exchange-traded funds (ETFs) have experienced negative net outflows for eight consecutive trading days. On Tuesday alone, $333.6 million was withdrawn, with IBIT contributing $192.4 million. Since May 14 (the last day of positive inflows), over $2 billion has exited these investment vehicles.
Institutional trading firm Jane Street reduced its Bitcoin ETF allocation by approximately 70% in the first quarter. Meanwhile, Morgan Stanley also decreased its Bitcoin ETF exposure by 10% during the same period. These strategic reductions indicate a more cautious approach from institutions regarding Bitcoin-related investment products.
The broader cryptocurrency investment environment is facing similar challenges. According to CoinShares analysis, digital asset investment products saw an outflow of $1.47 billion last week, with Bitcoin-related products accounting for $1.315 billion and Ethereum products losing $223 million. This marks the third-largest weekly capital outflow in 2026.
