US spot bitcoin ETFs lost a net $643.2 million on Friday, 30 Oct, according to Farside data, the largest daily outflow since 25 Jun. CryptoWatchDesk’s last ETF Desk covered Thursday’s $17.2 million inflow, the fourth day of a run that Friday ended.

Five funds accounted for all of it. BlackRock’s IBIT lost $233.7 million, Fidelity’s FBTC $201.0 million, ARK 21Shares’ ARKB $129.5 million, Grayscale’s GBTC $53.3 million and Bitwise’s BITB $25.7 million. Every other bitcoin fund reported no flow.

Ether funds lost a net $155.7 million, a fifth straight day of outflows, led by $76.6 million from BlackRock’s ETHA. Solana funds lost $10.8 million.

Friday was the first full US session after the Binance hack, which began after Thursday’s close. Farside’s data show what moved, not why.
