The iShares Bitcoin Trust (IBIT), a spot Bitcoin ETF managed by BlackRock, has experienced its largest daily outflow in its history. According to SoSoValue, investors withdrew $523.15 million from the fund on November 18, a record high since the product's launch in the US market.
This negative trend has been ongoing for several weeks. Since the end of October 2025, cumulative outflows from IBIT have exceeded $2 billion on a weekly basis. A similar situation is evident across the entire US spot Bitcoin ETF sector: analysts have recorded a negative balance of capital inflows and outflows for the fifth consecutive day. These trends are unfolding amid a general decline in Bitcoin's price, which began after a major sell-off in early October and has yet to be offset by the market.
IBIT remains the largest spot Bitcoin ETF in the market, controlling approximately $72.76 billion in assets. Industry participants attribute the massive withdrawals to investors' attempts to lock in profits or mitigate potential losses amid ongoing uncertainty about the price dynamics. However, some experts believe such a significant outflow does not indicate a loss of interest in the asset.
Vincent Liu, CIO at Kronos Research, commented to The Block that the current processes resemble a fundamental restructuring of institutional portfolios rather than a panic sell-off. He argued that large investors are temporarily reducing risk, awaiting clearer signals from the macroeconomic environment. Liu emphasized that institutional demand for Bitcoin remains robust, and investment activity could resume once the market situation stabilizes.
Bloomberg Intelligence analyst Eric Balchunas expressed a similar position. He emphasized that the observed outflow should not mislead the market: funds had accumulated significant Bitcoin holdings even before the October correction, and the sector as a whole is showing relatively stable performance. According to him, the current dynamics appear to be more of a technical correction than a fundamental problem.
Therefore, the record withdrawals from IBIT reflect tension in the cryptocurrency market, but do not necessarily indicate a decline in institutional interest in Bitcoin. While investors await clearer signals, the sector continues to adapt to the changed market conditions, which inevitably impacts the short-term performance of the largest funds.
