US spot Bitcoin and Ether ETFs moved in opposite directions on Tuesday, October 6. Bitcoin funds drew fresh money even as the price slipped, while Ether funds posted a sixth straight session of outflows.
What happened to Bitcoin and Ether ETF flows on October 6?
US spot Bitcoin ETFs took in about $119 million net on October 6, according to SoSoValue data reported by Cointelegraph . That reversed about $90 million of outflows on October 5. On the same day, spot Ether ETFs had their sixth straight session of outflows, which brought the six-day total to about $408 million .
Quick Answer: On October 6, 2026, US spot Bitcoin ETFs took in about $119M net while BTC fell below $84,000. Spot Ether ETFs lost $201.89M that day, their sixth straight outflow session, which brought the six-day total to roughly $408M (SoSoValue data via Cryptopolitan).
Cryptopolitan puts the exact Bitcoin figure at $118.86 million. The Ether side is the number that stands out. Ether ETFs lost $201.89 million on October 6, more than three times the size of any of the five sessions before it .
The Bitcoin inflow came while the price was falling. BTC dropped from above $86,600 to below $84,000. It traded at $83,971 when Cointelegraph published, down 2.1% over 24 hours .
Here is a snapshot of both fund groups at Tuesday's close:
- Bitcoin ETF net assets: about $110.68 billion
- Bitcoin ETF trading volume: about $1.84 billion
- Ether ETF net assets: about $17.36 billion, down from $17.69 billion on Monday
- Ether ETF trading volume: $719.91 million
The two asset groups pulled apart on the same day. For traders, the question is whether the split shows money rotating within crypto or reflects a small number of large allocators. TokenPost and CryptoBriefing both trace most of the activity to BlackRock's funds.
Why did Bitcoin ETFs gain $119M while the price fell?
Bitcoin ETFs gained $119 million while the price fell mainly because one fund drove the buying: BlackRock's IBIT. Investors bought into the dip. The flows did not follow the price. Cointelegraph reported that the October 6 inflow reversed roughly $90 million of outflows from Monday, October 5 .
The fund-level breakdown shows how concentrated the day was:
- BlackRock IBIT: about $122 million in, which is more than the net total for the whole sector .
- Morgan Stanley MSBT: $7.84 million in .
- Grayscale Bitcoin Mini Trust: $10.97 million out, which offset part of those gains .
The price did not respond to the inflow. According to Cointelegraph, BTC fell from above $86,600 to $83,971, down 2.1% over 24 hours . On-chain data helps explain why. BTC trades well above the estimated cost basis of active traders, which is about $68,900. That leaves many holders sitting on profits they can sell.
"Sustaining the recovery would depend on whether fresh demand could absorb that selling," — MorenoDV, contributor at CryptoQuant (source: Cointelegraph)
Not all of the inflow is new money. Cryptopolitan noted that lower thresholds for in-kind transfers have "opened the floodgates" for holders who want to move bitcoin they hold directly into ETF shares . An in-kind transfer means delivering actual coins to the fund instead of cash. When that happens, ownership changes form, but no new buying reaches the spot market. As a result, part of Tuesday's $119 million may be a change in how existing holders keep their bitcoin rather than fresh demand.
How big is the Ether ETF outflow streak, day by day?
The Ether ETF outflow streak totals about $407.8 million over six sessions . Most of it arrived in one day. The first five sessions were modest, and none of them lost more than $60 million. Then October 6 alone took out more than three times the size of any earlier day, according to Cryptopolitan, which used SoSoValue data.
| Session | Net Ether ETF outflow |
|---|---|
| Sept 29 | $2.81M |
| Sept 30 | $59.58M |
| Oct 1 | $55.37M |
| Oct 2 | $37.36M |
| Oct 5 | $50.76M |
| Oct 6 | $201.89M |
| Total | ~$407.8M |
All of Tuesday's $201.89 million came from BlackRock's iShares Ethereum Trust (ETHA). No other Ether ETF recorded net flows that day . That means a single fund accounts for almost half of the six-day total (source: CryptoBriefing, 2026-10).
Cryptopolitan calls Tuesday the largest daily Ether outflow since September 16. The comparison depends on which measure you use:
- Sector-wide: all Ether ETFs lost $224.11 million on Sept 16 . That is the measure behind "largest since."
- ETHA only: BlackRock's fund lost about $110 million on Sept 16 . On that single-fund basis, Tuesday's ETHA redemption was much larger.
The streak started right after a period of strong buying. Ether ETFs took in about $690 million during the week of September 21 , according to 24/7 Wall St. So far, the six sessions have reversed a bit more than half of that inflow.
The price has fallen with the flows. ETH dropped below $2,600 and traded near $2,562 on October 7, down about 5.5% over 24 hours , per GNcrypto.
Is this a rotation into Bitcoin or one big seller?
The data supports both readings, and neither is proven yet. The flows look like money moving within crypto: Ether left through ETHA on the same day IBIT led Bitcoin fund inflows. However, a single ETHA redemption of $201.89M made up nearly half of the six-day Ether total . That means one allocator could be driving the headline numbers.
The rotation argument comes from two outlets. CryptoBriefing sees the split as investors reallocating within crypto, not leaving the asset class. The Currency Analytics describes it as a possible move toward Bitcoin, which investors may treat as the safer asset when markets are volatile .
The streak is small compared with the total size of the Ether funds. Ether ETFs still have about $13.55 billion in cumulative net inflows since they launched in July 2024, and ETHA alone accounts for about $13.04 billion of that . Because ETHA holds so much of the sector, a redemption at BlackRock shows up as a sector-wide outflow.
Ether ETF assets now equal about 5.27% of ETH's market cap . A six-day outflow of $408M is a meaningful drop, but it does not mean institutions are leaving Ether.
Other signals give mixed hints:
- Leverage: Ethereum's estimated leverage ratio fell to a seven-month low, which suggests less speculative positioning in ETH , according to PrimeXBT.
- Other altcoin ETFs: XRP ETFs took in a net $3.1M and Solana ETFs lost about $3.7M on October 6 . That is too small to show a broad move out of altcoins.
Rotation fits the data best for now. Still, as long as one ETHA holder can account for half a week's outflows, the evidence for a sector-wide shift is limited.
What should traders watch next?
Traders should watch three things: whether the Ether outflow streak ends, whether Bitcoin ETFs keep drawing money while the price is weak, and where BTC trades relative to the cost basis of active traders. On October 6, IBIT took in about $122 million while ETHA lost $201.89 million , according to Cryptopolitan. Whether that split continues will decide if the rotation explanation holds.
- ETHA flows: One day of inflows at BlackRock's fund would break the six-session streak. ETHA holds about $13.04 billion of the sector's $13.55 billion in cumulative inflows , so its flows largely set the sector's direction (source: CryptoBriefing, 2026-10).
- IBIT with BTC below $84K: BTC traded near $83,371 on October 7 . If IBIT keeps taking in money at that level, the buying looks like steady demand rather than one session of dip-buying.
- Cost-basis gap: CryptoQuant's MorenoDV estimates active traders' cost basis at about $68,900 . While BTC trades well above that level, holders still have profits to take, so new ETF demand has to absorb that selling (source: Cointelegraph).
Treat ETF flows as a daily signal, not a price forecast. Check SoSoValue after each US session, and keep sector-wide totals separate from single-fund figures. One ETHA redemption made up nearly half of the six-day Ether total. The practical takeaway: wait for two or three sessions in a row of matching flows before reading them as a trend.

How much have Ether ETFs lost during the six-session streak?
US spot Ether ETFs lost about $408 million over six straight sessions, from September 29 to October 6, 2026 . The last day was the largest. On October 6 the funds lost $201.89 million, and all of it came from BlackRock's iShares Ethereum Trust (ETHA), according to CryptoBriefing . None of the first five sessions lost more than $60 million.
Why are Bitcoin ETFs seeing inflows while the BTC price falls?
Several things could explain Bitcoin ETF inflows during a price drop, and daily flow data can't show which one is behind them. Some buyers may be purchasing the dip. Others may be moving money out of Ether and into Bitcoin. Existing holders may also be converting bitcoin they hold directly into ETF shares, since Cryptopolitan notes that lower in-kind transfer thresholds have made this easier. During the inflow, BTC slipped below $84,000 and traded at $83,971, down 2.1% over 24 hours .
Does an Ether ETF outflow streak mean investors are leaving crypto?
Not necessarily. The single ETHA redemption on October 6 makes up nearly half of the six-day total, so one holder or allocator can drive the headline number. Since the July 2024 launch, Ether ETFs still hold about $13.55 billion in cumulative net inflows . Both CryptoBriefing and The Currency Analytics read the split as money moving from Ether to Bitcoin, not money leaving the asset class.
