U.S. spot Bitcoin funds see $643.2 million in outflows on Oct. 30
Key Facts
U.S. spot Bitcoin funds recorded net outflows of $643.2 million on Oct. 30, 2026, according to Farside Investors’ data, reversing the inflows that preceded the session. The withdrawals followed four consecutive days of positive flows, from Oct. 26 to 29. The largest single outflow came from BlackRock’s IBIT, at $233.7 million. Fidelity’s FBTC saw outflows of $201.0 million, while Ark Invest’s ARKB recorded $129.5 million in outflows. Another $53.3 million flowed out of Grayscale’s GBTC and $25.7 million from Bitwise’s BITB. The withdrawals coincided with pressure on the cryptocurrency market following a security incident announced by Binance, but the timing does not prove that the incident caused the fund flows.
The funds had attracted $110.3 million on Oct. 26, followed by $176.0 million on Oct. 27. Net inflows reached $137.3 million on Oct. 28, before slowing to $17.2 million on Oct. 29. The Oct. 30 session broke that streak, with net outflows exceeding the total inflows in each of the previous four sessions. Farside’s figures show differences among the funds, with IBIT accounting for the largest share of withdrawals that day. FBTC followed, then ARKB, while GBTC and BITB recorded smaller outflows. The data did not identify why investors withdrew money from the funds.
In the broader market, the Associated Press said Bitcoin fell 3.2% on Thursday evening, Oct. 29, to below $79,000. A Reuters report said the cryptocurrency had hit a six-week low and was down 3% at $76,469.82 at the time of the report on Oct. 30. Ether also fell more than 3% to $2,185.83, according to the same report. EL7 data showed Bitcoin against the dollar closing at $77,368.77 on Oct. 30, then at $77,543.01 on Oct. 31. These figures are readings recorded at different times, including two daily closes and a price snapshot at the time of the Reuters report. Coinbase shares also fell 4.8%, while Strategy shares dropped about 6% in extended U.S. trading on Oct. 30, Reuters reported.
Binance announced a security incident and estimated its total impact at about $6.3 billion, saying it had frozen about $3 billion in affected on-chain assets. The agency said the company’s initial investigation indicated the incident may have been linked to a compromised laptop belonging to an engineer on the development operations team, which gave the attacker access to a service container and enabled unauthorized withdrawal transactions. Binance said it had found no evidence that the wallet’s private key was leaked. In a later report, the company’s co-CEO confirmed that Binance’s hot wallet was affected, while the company said most user assets are held in cold wallets. Binance temporarily suspended all deposits and withdrawals during security checks, the freezing of funds and cooperation with law enforcement. These details, or their timing, do not establish whether the incident caused the U.S. fund outflows.
Binance said it would cover losses related to the incident through its SAFU fund and company funds, noting that it had allocated more than $6.34 billion, including $5 billion in assets matching those affected. The company said its technical team was targeting a gradual resumption of withdrawals within about 34 hours, subject to completion of security checks. It also said it planned to conduct an initial proof-of-reserves snapshot within 12 hours, with the result expected by Nov. 2, 2026. These timelines remain targets announced by the company on Oct. 30, and it tied the resumption of withdrawals to completion of the checks. A Reuters report quoted a Standard Chartered analyst as saying negative price pressure could persist until frozen assets are released and details of the breach become clear. The analyst said: "We will not find a new base until the assets are unfrozen and more details about the breach emerge."
