Background and Impact
According to SoSoValue data, on October 30, U.S. Eastern Time, U.S. Bitcoin spot ETFs had combined net outflows of $643 million. Odaily Planet Daily published the data at 04:22 on October 31, 2026, and PANews followed up with a report at 04:29 the same day. The core figures from the two sources are consistent: BlackRock's IBIT had single-day net outflows of $234 million, the largest net outflow among Bitcoin spot ETFs that day; Fidelity's FBTC had single-day net outflows of $201 million, ranking second. Neither report disclosed the daily details of the other individual products, nor did they explain the composition of each product's net asset value changes and subscription/redemption transactions.
From the cumulative data, the single-day outflow did not change the fact that both products' historical net inflows remained positive. Reports show that IBIT's cumulative historical net inflow was $66.311 billion, and FBTC's cumulative historical net inflow was $10.172 billion. As of press time, the total net assets of Bitcoin spot ETFs were $98.140 billion, the ETF net asset ratio (the proportion of ETF market value to Bitcoin's total market value) was 6.34%, and cumulative historical net inflows were $56.980 billion. The above metrics are all provided by SoSoValue, and the two sources cite the same set of numbers. The only visible difference is at the wording level: in PANews' summary, FBTC's outflow amount was truncated and displayed as "2.0," while its main text and the Odaily report both say $201 million, which does not constitute a data discrepancy.
In terms of scope of impact, $643 million is a single-day flow metric, and it is on a different time scale from the $98.140 billion total net assets of the ETFs and the $56.980 billion cumulative historical net inflows. Neither report gave reasons for the outflows or mentioned comparative data for other trading days; therefore, the available material is insufficient to support a judgment on whether the single-day data can represent a trend. It should be noted that ETF fund flow data is disclosed by data platforms such as SoSoValue and belongs to a different category of search demand from entry-point information on trading platforms. For example, some readers may look up pages such as Huobi HTX registration APP download, Zhima Gate.io registration APP download, Bitget registration APP download, Binance registration APP download, and OKX registration APP download; these pages are not directly related to ETF subscription and redemption data and should not be substituted for or mixed with each other.
Subsequent points to watch include: ETF net inflow/outflow data for October 31, U.S. Eastern Time, and later trading days, and whether total net assets and the net asset ratio adjust with price and subscription/redemption changes. As of the publication time of both sources, none of the above follow-up data had been disclosed.
Frequently Asked Questions
### Does a $643 million net outflow mean institutional funds are withdrawing from Bitcoin as a whole?
The available material only supports the conclusion of "a single-day net outflow of $643 million." The same set of data shows that cumulative historical net inflows into Bitcoin spot ETFs remain $56.980 billion, and total net assets are $98.140 billion. Neither source provided reasons for the outflows or a trend judgment.
### Will BlackRock IBIT's cumulative historical net inflow of $66.311 billion be erased by this outflow?
No. The $234 million is IBIT's single-day net outflow on October 30, U.S. Eastern Time, and its cumulative historical net inflow is still recorded in the reports as $66.311 billion. The two are metrics on different time scales and cannot be directly subtracted from each other or substituted for each other.
### Which data points should be watched next?
First, ETF net inflow/outflow data for October 31, U.S. Eastern Time, and later trading days; second, changes in total net assets and the ETF net asset ratio (currently 6.34%). As of press time, neither report disclosed data for subsequent trading days.
