Key Takeaways
BlackRock’s $1.01 billion Bitcoin sale was driven by investor redemptions from its IBIT ETF, not by the firm abandoning Bitcoin.
A record $1.29 billion IBIT dark pool block trade intensified fears of institutional de-risking in the crypto market.
Around 15,000 BTC were transferred to Coinbase Prime in daily batches to settle ETF withdrawals.
BlackRock’s $1 billion Bitcoin sell-off last week sparked panic across crypto markets, prompting traders to question whether the world’s largest asset manager was turning bearish on Bitcoin.
However, blockchain data and ETF flow figures suggest the reality is far less dramatic: the selling largely reflected investor withdrawals from BlackRock’s iShares Bitcoin Trust (IBIT), not a strategic retreat from crypto by the firm itself.
The wave of redemptions came during the heaviest week of US spot Bitcoin ETF outflows in 2026, with investors pulling roughly $1.26 billion from the market between May 18 and 22.
At the same time, BlackRock continued expanding its digital asset footprint, with its tokenized fund business surpassing $2.5 billion in assets, underscoring the company’s long-term commitment to blockchain-based finance despite short-term turbulence in Bitcoin markets.
BlackRock’s IBIT accounted for the majority of last week’s ETF withdrawals, with approximately $1.01 billion worth of Bitcoin sold to settle investor redemptions.
On-chain tracker Arkham reported that nearly 15,000 BTC were transferred in daily batches to Coinbase Prime, the institutional trading platform commonly used for ETF settlements.
The transactions fueled speculation on crypto social media after Arkham posted that BlackRock had sold Bitcoin every day during the week.
However, analysts noted that the sales were not initiated by BlackRock itself. Instead, the firm was carrying out routine ETF redemption processes as investors exited the fund.
The broader ETF market also experienced significant pressure. US spot Bitcoin ETFs recorded eight consecutive trading days of net outflows, with Tuesday alone seeing net outflows of more than $333 million. IBIT represented nearly $192 million of that figure.
Bitcoin briefly dropped to around $74,300 during the sell-off before recovering toward the $77,000 level. Analysts said the rebound appeared to be driven more by speculative futures activity than by long-term spot-buying demand.
Despite the heavy selling, ETF markets remained orderly, with liquidity holding up across major products. Spot Bitcoin ETFs collectively still hold roughly 1.3 million BTC, equivalent to nearly 7% of Bitcoin’s circulating supply.
Market attention intensified after a massive $1.29 billion block trade involving IBIT shares crossed Nasdaq through a dark pool transaction on Tuesday.
According to Bloomberg ETF analysts Eric Balchunas and James Seyffart, the trade involved approximately 29.2 million IBIT shares sold at around $43.16 per share.
Dark pool trades are privately negotiated transactions executed outside public exchanges, typically used by institutions seeking to move large positions without disrupting markets.
Balchunas described the transaction as one of the largest Bitcoin ETF trades ever recorded, noting that the market “absorbed it well” despite the size of the order.
Galaxy Digital Head of Research Alex Thorn called it the largest dark pool Bitcoin ETF trade he had personally observed. Some analysts interpreted the transaction as a sign of institutional de-risking amid broader macroeconomic uncertainty and declining appetite for risk assets.
The trade coincided with a sharp intraday decline in Bitcoin’s price. Data showed BTC fell nearly 1.5% within minutes of the block trade, then extended losses later in the day.
Institutional sentiment toward Bitcoin ETFs has softened in recent months. Jane Street reportedly reduced its Bitcoin ETF holdings by roughly 70% during the first quarter of 2026, while Goldman Sachs also trimmed exposure.
Even as Bitcoin ETF flows weakened, BlackRock continued advancing its broader blockchain strategy.
The asset manager recently filed paperwork for another tokenized investment product with the US Securities and Exchange Commission, while its existing tokenized fund business surpassed $2.5 billion in assets under management.
The milestone reinforces BlackRock CEO Larry Fink’s increasingly vocal support for tokenization, which he has repeatedly described as the future of capital markets.
Tokenized funds use blockchain technology to represent traditional financial assets digitally, enabling faster settlement and potentially broader market access.
Industry analysts say BlackRock’s continued investment in tokenization suggests the firm remains committed to digital assets even as Bitcoin faces cyclical volatility.
For now, market watchers are closely monitoring ETF flows as a key indicator of institutional demand. Analysts say Bitcoin’s ability to hold above critical support levels despite multi-billion-dollar outflows may indicate that the recent selling reflects temporary risk reduction rather than a structural collapse in institutional crypto adoption.
