U.S. spot bitcoin ETFs lost $244.1 million on Thursday 8 October 2026, their second consecutive outflow day, following a $484.9 million exit on Wednesday. Together the two sessions took out $729.0 million — more than twice the $321.6 million the funds had gathered in the first four sessions of October, which this desk reported a day earlier (ETF flows update, 8 October). Month-to-date net flow is now −$407.4 million, according to Farside Investors' daily table, and Fidelity's FBTC alone (−$408.1 million) matches the whole net outflow.
The eight-session table
All figures below are net flows in millions of U.S. dollars from Farside; parentheses in the source mean outflows, shown here with a minus sign. “Others” is the total minus IBIT, FBTC and GBTC, calculated by this desk.
| Date | Total | IBIT | FBTC | GBTC | Others (calc.) |
|---|---|---|---|---|---|
| 29 Sep | +66.2 | +51.1 | 0.0 | 0.0 | +15.1 |
| 30 Sep | −148.7 | −9.5 | −125.6 | 0.0 | −13.6 |
| 1 Oct | +102.7 | +195.6 | −60.7 | −31.4 | −0.8 |
| 2 Oct | +189.9 | +158.2 | +29.3 | 0.0 | +2.4 |
| 5 Oct | −89.8 | +69.9 | −74.5 | 0.0 | −85.2 |
| 6 Oct | +118.8 | +122.0 | 0.0 | 0.0 | −3.2 |
| 7 Oct | −484.9 | −207.7 | −105.1 | −39.3 | −132.8 |
| 8 Oct | −244.1 | −5.5 | −197.1 | −8.2 | −33.3 |
| 1–8 Oct | −407.4 | +332.5 | −408.1 | −78.9 | −252.9 |
What changed on Thursday
The composition of the outflow shifted. On Wednesday BlackRock's IBIT led the exits with −$207.7 million. On Thursday IBIT was nearly flat at −$5.5 million, and the selling came from Fidelity's FBTC (−$197.1 million, its largest single-day outflow in this eight-session window; the previous largest was −$125.6 million on 30 September), plus about $33 million from the smaller funds and $8.2 million from Grayscale's GBTC. The smaller funds in the “Others” group include BITB, ARKB, BTCO, EZBC, BRRR, HODL, BTCW, MSBT and the Grayscale Mini Trust, per TFTC's fund list.
Across the month so far, the picture is a split. IBIT has taken in $332.5 million net. Everything else combined has lost $739.9 million (FBTC −$408.1 million, other funds −$252.9 million, GBTC −$78.9 million). In other words, the month's net outflow is not a broad exodus from the largest fund; it is concentrated in the other issuers.
Price context: the outflow days were the down days
Bitcoin fell 2.65% on Wednesday to close at $83,275.06 and 1.90% on Thursday to close at $81,692.79 (Coinbase Exchange, UTC days), touching $80,314.70 intraday, its lowest since 20 September. The two outflow days therefore coincided with the two biggest down days of the month. The ETF flow figures are for the U.S. trading day, while the bitcoin candles run midnight to midnight UTC, so the alignment is approximate. It also does not establish cause: Thursday's decline accompanied a 1.25% Nasdaq drop on a report about OpenAI's revenue (our news report) and about $1.16 billion of liquidations (how to read that number). ETF redemptions can follow price falls as well as contribute to them.

Two data sources, small differences
This desk cross-checks flows against a second tracker. TFTC's October page, which had data through 7 October when we read it, shows −$487.1 million for Wednesday against Farside's −$484.9 million, and +$189.8 million for 2 October against Farside's +$189.9 million. The gaps come from per-fund rounding and do not change any conclusion; we use Farside's totals throughout because its table already included Thursday. Neither source states a cumulative figure for the funds' lifetime net inflow in the pages we read, so we do not quote one.
What flow data can and cannot tell you
- It shows net creations and redemptions, not motives. A fund losing money on a day could reflect long-term holders selling, traders reducing exposure, or arbitrage positions being unwound; the table does not distinguish them.
- It is a daily snapshot. Two outflow days after a strong run of inflows (+$66.2 million, +$102.7 million, +$189.9 million and +$118.8 million on the positive days) is a change in direction, not yet a trend.
- It is a lagging indicator. Flows are reported after the U.S. close, so they describe what funds did while bitcoin was already moving.
What to watch next
- Friday 9 October flow print: published after the U.S. close. A third straight outflow day, with bitcoin near $82,400 this morning, would extend the run; an IBIT-led inflow would suggest the largest fund is again the marginal buyer.
- Wednesday 14 October, 8:30 a.m. ET: U.S. consumer prices for September (BLS schedule).
- Wednesday 28 October, 2 p.m. ET: the FOMC decision (FOMC calendar).
