Bitcoin ETFs Shed $635.6M in a Day as BTC Slides Toward $80,000

U.S. spot bitcoin ETFs bled $635.6 million on October 22, Farside Investors data show — a $1.16 billion one-day swing from the prior session’s $524.8 million inflow, and the largest single-day outflow of October. Bitcoin slid to $80,939.54, within 1.2% of the $80,000 level, as a 2.6% Nasdaq rout drained risk appetite across markets.

The flow reversal

The institutional bid for bitcoin snapped on Thursday.

Farside Investors’ daily flow table shows U.S. spot bitcoin ETFs recorded a combined $635.6 million net outflow for the October 22 session, with every major fund in the red: BlackRock’s IBIT lost $254.1 million, Fidelity’s FBTC $217.5 million, ARK 21Shares’ ARKB $109.4 million and Grayscale’s GBTC $29.5 million. The figures were published in Farside’s end-of-day update at 19:47 UTC on October 22, and the total was corroborated by a second reading of the same dataset published October 23.

U.S. spot bitcoin ETF net flows ($ millions)

Fund	October 21	October 22
IBIT (BlackRock)	+235.0	-254.1
FBTC (Fidelity)	+212.7	-217.5
ARKB (ARK 21Shares)	+9.8	-109.4
GBTC (Grayscale)	+32.6	-29.5
Total net flow	+524.8	-635.6

The scale of the reversal is the story. One session earlier, the same complex had taken in $524.8 million — IBIT drew $235 million and FBTC $212.7 million, with seven funds positive and none in the red. TECHi’s calculation puts the one-day swing at $1,160.4 million, from inflow to outflow. At the fund level the whiplash is even starker: FBTC reversed $430.2 million (from +$212.7 million to -$217.5 million) and IBIT reversed $489.1 million (+$235 million to -$254.1 million). The three-session inflow streak of $1.0747 billion from October 19 to 21 — $526.7 million on the 19th, $23.2 million on the 20th, $524.8 million on the 21st — lost well over half its total in a single day.

Thursday’s print also stands out against the month’s earlier damage. The funds had lost a net $484.9 million on October 7 and $261.4 million on October 14, in a stretch that saw weekly withdrawals reach $679 million in early October. The October 22 outflow of $635.6 million exceeds both of those daily prints, making it the heaviest single-day redemption of the month — and a reminder that the mid-month rebuild was built on just three sessions.

The price action

Bitcoin fell with the flows. It traded at $81,683.93 at about 05:30 UTC on October 23, down 1.4% from the previous close of $82,840.06, after touching $80,939.54 in the session — 1.17% above the psychologically key $80,000 level, and the day’s low on the Binance feed. Live pricing is tracked on CoinGecko’s bitcoin page.

The $80,000 line matters because it has become the market’s shorthand for whether the October bounce has failed. Bitcoin had climbed back toward $84,800 earlier in the week as the ETF inflow streak ran; Thursday’s slide erased that cushion in a single session. A sustained break below $80,000 would reopen the lower part of October’s range and test whether any dip-buying remains outside the ETF complex.

Ether fared worse in percentage terms: $2,396.87 at the same timestamp, down 1.97% from $2,444.93, with a session low of $2,360.32. The second-largest cryptocurrency has now given back its entire mid-week recovery, and it trades more than 11% below its late-September levels.

Ether ETFs bled too

The selling was not confined to bitcoin products. U.S. spot ether ETFs recorded a $110 million net outflow on October 22, with BlackRock’s ETHA losing $75.5 million and ETHB $17.2 million, according to the same Farside dataset. Ether funds had already endured a difficult October, shedding $542.2 million in the week of October 5–9, and Thursday’s print shows the pressure has not lifted even as bitcoin products briefly stabilized.

Why it happened

Equities set the tone. The Nasdaq Composite fell 2.6% to 26,008.86 on Thursday — its steepest single-session drop since June 5 — while the S&P 500 lost 1.2% to 7,663.43, its worst day since July. The Philadelphia Semiconductor Index dropped 6.72%, Brent crude settled at $113.17 — its highest since May 4 — the VIX jumped 14.09% to 19.03, and the 10-year Treasury yield slipped below 5% to 4.96% as money sought safety.

The proximate trigger sat inside the AI trade itself. Meta’s third-quarter results, which TECHi covered here, put the AI capital-spending boom back under the microscope: the day after the report, investors repriced how the spending gets financed, and chipmakers led the retreat, with Lam Research falling 11.8% and Nvidia 4.4%. When the Nasdaq sheds roughly $1 trillion of market value in a session, bitcoin — which trades around the clock and has no circuit breakers — absorbs the de-risking first and fastest.

Oil added a second headwind. Brent’s settlement at $113.17 raises the inflation path the Federal Reserve must price against at its October 27–28 meeting, and a higher-for-longer rate outlook has historically pressured non-yielding assets like bitcoin as fixed income offers a safer carry.

What the flows actually say

What the flows actually say about institutional demand is narrower than the headline suggests — and more fragile. Farside puts cumulative net flows into the U.S. spot bitcoin products at $58.02 billion, with IBIT accounting for $66.50 billion of that and GBTC sitting at negative $27.97 billion. Against that base, a $635.6 million day is about 1.1% of the all-time total: meaningful as a signal, small as a stock.

The signal is concentration. The same two funds that supplied roughly 85% of October 21’s inflow — IBIT and FBTC at a combined $447.7 million — accounted for the bulk of the next day’s outflow. When two products drive the complex in both directions, the “institutional bid” is really a handful of allocation decisions, and it can reverse in a single session. The steep bitcoin rallies since these funds launched were built on months of steady buying; the pace since July has fallen well short of that, and October’s flow chart now reads as two steps forward, one large step back.

Fund flows, it bears repeating, measure money entering or leaving the vehicles. They do not capture every bitcoin trade, reveal each buyer’s holding period, or establish that an investor has no offsetting position elsewhere. A daily creation figure is not a timetable. But direction matters: when the two largest ETFs swing by nearly half a billion dollars each in 24 hours, the institutional bid is not a floor — it is a weather vane.

The broader crypto market felt the same wind even as networks kept shipping. Solana’s Alpenglow upgrade went live this week, Ethereum’s Hoodi testnet upgrade for Glamsterdam was postponed to a date to be announced, and Zcash set its NU7 activation block as ZEC rallied — yet prices followed macro, not milestones. TECHi’s Bitcoin stock page tracks the price action.

What to watch

• Friday’s session flow print, due Saturday morning UTC: does the outflow extend into a streak, or was Thursday a one-day flush?
• The $80,000 level: a sustained break would put October’s lows back in play and test dip-buying outside the ETF complex.
• The Federal Reserve’s October 27–28 meeting, with Brent above $113 complicating the inflation path and the rate outlook for non-yielding assets.
• The November 30 MSCI decision on whether Strategy stays in its indexes — the next test of institutional crypto demand.
