US spot crypto ETF flows split sharply in October 2026. Bitcoin ETFs are roughly flat for the month, while Ether ETFs have seen outflows on 15 of 18 trading days. We totalled the daily figures published by Farside Investors for 1 to 26 October 2026 and compared them with August and September.

Key numbers

• Bitcoin ETFs: net outflow of $203.2 million over 18 trading days (10 inflow days, 8 outflow days). In September the same funds took in $2,647.7 million, in August $3,539.1 million.
• Ether ETFs: net outflow of $1,264.4 million, with only 3 inflow days (13, 21 and 23 October). September was a net inflow of $831.3 million, August $1,851.5 million.
• One fund carries Bitcoin: BlackRock’s IBIT took in $865.5 million, while all other US spot Bitcoin ETFs together lost $1,068.7 million. Fidelity’s FBTC (minus $588.5 million) and ARK’s ARKB (minus $314.5 million) had the largest outflows.
• One fund drives Ether outflows: BlackRock’s ETHA lost $1,134.1 million, about 90% of the Ether ETF total. Grayscale’s ETHE lost $82.1 million.
• Prices: on CoinGecko, bitcoin fell from about $83,576 (1 October, 00:00 UTC) to about $80,029 (27 October, 00:00 UTC), minus 4.2%. Ether fell from about $2,685 to about $2,321, minus 13.6%.

Bitcoin ETFs: big swings, flat total

Bitcoin ETF flows moved in large blocks. The two biggest inflow days were 19 October (plus $526.7 million) and 21 October (plus $524.8 million). They were almost cancelled by the two biggest outflow days, 22 October (minus $635.6 million) and 7 October (minus $484.9 million). On Monday, 26 October, IBIT reported plus $110.3 million and every other fund reported zero. Since the first US spot Bitcoin ETFs launched in January 2024, cumulative net inflows stand at about $57.36 billion on Farside’s table.

Ether ETFs: a steady drip

Ether ETF outflows were smaller per day but very consistent. The worst day was 6 October (minus $201.9 million) and the biggest inflow was only $24.8 million on 13 October. Cumulative net inflows into US spot Ether ETFs fell from about $13.92 billion at the end of September to about $12.66 billion, a drop of roughly 9% in under four weeks. Ether also underperformed bitcoin on price over the same period.

What it means for spot buyers

ETF flows show what US institutional and advisory money is doing, not where prices must go next. Flows often follow price rather than lead it. If you buy coins directly rather than through an ETF, your own costs matter more: trading fees, spreads and how you fund your account. Our bitcoin spread test across 9 exchanges shows that the fee tier usually decides the cost of a normal-sized buy.
