Bitcoin ETFs Just Lost $643 Million in One Day — the Biggest Exit Since June

U.S. spot Bitcoin ETFs lost $643.2 million in a single day on Friday, October 30 — their biggest daily withdrawal since June — while spot Ether ETFs lost another $155.7 million, capping a $1.61 billion October exit. The combined $798.9 million one-day outflow, tracked by Farside Investors, wiped out four straight days of Bitcoin ETF buying and turned the whole week negative, in the clearest sign yet that institutional crypto demand cracked at the end of October.

What happened, in one paragraph

Investors pulled $643.2 million from U.S. spot Bitcoin ETFs on the final trading day of October, according to Farside Investors data reported by crypto.news and other outlets. It was the largest one-day exit since the $691.7 million withdrawn on June 25, and it narrowly beat the $635.6 million pulled on October 22. Ether ETFs were hit at the same time: $155.7 million left on Friday alone, and U.S. spot Ether funds have now recorded 23 consecutive outflow sessions, the longest streak since they launched, according to Glassnode data reported by Blockonomi.

Which funds lost the most?

Three issuers accounted for $564.2 million — about 87.7% — of Friday's Bitcoin ETF withdrawals. BlackRock's IBIT, the largest spot Bitcoin fund, led with $233.7 million in outflows, followed by Fidelity's FBTC at $201 million and ARK 21Shares' ARKB at $129.5 million. Grayscale's GBTC lost $53.3 million and Bitwise's BITB lost $25.7 million, and none of the other Bitcoin products in Farside's table recorded a positive flow that day. On the Ether side, BlackRock's ETHA lost $76.6 million on Friday, Grayscale's Ethereum Mini Trust lost $34.1 million, its ETHE product lost $21.5 million, BlackRock's ETHB shed $19.5 million, and Fidelity's FETH lost $3.3 million.

One bad day erased a good week

The timing is what makes the number sting. Bitcoin ETFs had collected $440.8 million across October 26–29 — $110.3 million on Monday, $176 million on Tuesday, $137.3 million on Wednesday and $17.2 million on Thursday. Friday's exit was bigger than all four days combined, leaving the week at minus $202.4 million. October as a whole ended at about $515.9 million in net Bitcoin ETF outflows, even though IBIT alone took in $932.1 million during the month while the other funds together lost roughly $1.45 billion. Ether funds finished every session of the final week negative, losing $431.4 million in five days — almost double the previous week's $220.7 million — and about $1.607 billion across October.

Why it's blowing up

The outflow landed at the end of a brutal week for risk assets. Stocks had just posted their worst October finish in months, and crypto was still dealing with the fallout of the $6.3 billion Binance hack disclosed on Thursday, the largest crypto theft on record. Ether faced an extra overhang: wallets linked to the hack were estimated on Saturday to hold about 525,200 ETH, according to reporting cited by Blockonomi, a potential supply risk if any of it is sold — though Binance says it has already replenished 90% of the stolen assets and will absorb the financial impact rather than passing it to users. Against that backdrop, the ETF numbers gave traders a hard, dated measure of something they had only suspected: the steady institutional bid that supported crypto through the autumn is, for now, going the other way.

The price level everyone is watching

Bitcoin traded near $77,364 on October 31, according to CoinGecko figures cited by crypto.news, after touching a 24-hour low of $76,337.84. That is below the $81,500 average purchase price Glassnode estimates for Bitcoin held by U.S. spot ETFs, and close to the $77,900 level Glassnode calls the True Market Mean — the average cost basis of active investors. Ether traded near $2,240 to $2,250 on Saturday after falling more than 5% on Thursday, with several outlets flagging $2,200 as the level traders are defending. None of that changes the long-term ETF picture yet: cumulative net inflows into U.S. Bitcoin ETFs since their January 2024 debut still stand above $57 billion, with IBIT's cumulative intake at $66.31 billion against GBTC's $28.05 billion of lifetime withdrawals.

What's next

The next test comes quickly. U.S. midterm elections fall on Tuesday, November 3, Binance has said withdrawals are set to resume on November 1, and traders will watch Monday's Farside table to see whether Friday was a one-day flush or the start of a longer exit. A return to inflows would suggest October ended with position-clearing; another large red day, especially from IBIT, would confirm that institutional demand has genuinely turned.
