Ethereum ETF vs Bitcoin ETF: both iShares funds charge 0.25%, so cost doesn’t separate them. Risk and liquidity do. Ether ETFs posted eight straight outflow days through October 8, 2026, losing $641.3 million per Farside, while ETHA fell 35.47% over 12 months versus IBIT’s 26.80%. For a single crypto ETF, the bitcoin fund wins on every measurable attribute except upside volatility.
Key takeaways
- Ether ETFs lost $641.3 million in eight straight outflow days, September 29 to October 8.
- IBIT holds $67.3 billion in net assets, about 7.8 times ETHA’s $8.7 billion.
- Over 12 months to September 30, ETHA returned -35.47% versus IBIT’s -26.80%.
What happened to Ethereum ETF flows this week?
US spot ether ETFs logged their eighth consecutive day of net outflows on Thursday, October 8, 2026. According to Farside Investors, the streak that began September 29 removed $641.3 million. BlackRock’s ETHA alone accounted for $450.0 million of it, roughly 70%.
The worst day was Tuesday, October 6. ETHA shed $201.9 million and no other ether fund moved. That was a single-fund exit, not a category-wide one.
Bitcoin funds bled too, but less in relative terms. Farside shows US spot bitcoin ETFs lost $484.9 million on October 7 and $244.1 million on October 8, a two-day total of $729.0 million. Fidelity’s FBTC took $197.1 million of Thursday’s outflow on its own.
Scale matters here. Per SoSoValue data cited by Cryptopolitan, bitcoin ETFs held $104.91 billion at Thursday’s close, while ether ETFs held $15.64 billion. A $641 million exit is about 4% of the ether complex. The bitcoin two-day exit is under 1% of its base.
Is an Ethereum ETF or a Bitcoin ETF cheaper to hold?
Neither, if you compare the flagship funds. IBIT and ETHA both carry a 0.25% sponsor fee, per BlackRock’s fund pages. The real cost gap shows up in trading: IBIT’s 30-day median bid/ask spread was 0.02% as of October 7, 2026, versus 0.05% for ETHA. The cheapest funds in each category tie at 0.14%.
The fee table below uses Farside’s fee row and the IBIT and ETHA issuer pages.
| Attribute | Bitcoin ETFs | Ethereum ETFs |
|---|---|---|
| Flagship fund | IBIT | ETHA |
| Flagship sponsor fee | 0.25% | 0.25% |
| Flagship net assets | $67.31B (Oct 7, 2026) | $8.68B (Oct 8, 2026) |
| Flagship 30-day median spread | 0.02% (Oct 7, 2026) | 0.05% (Oct 7, 2026) |
| Lowest fee in category | MSBT, 0.14% | MSSE, 0.14% |
| Highest fee in category | GBTC, 1.50% | ETHE, 2.50% |
| Cumulative net flows, all funds | $57.16B | $13.35B |
| Category assets (Oct 8, 2026) | $104.91B | $15.64B |

What a $10,000 position costs per year
The arithmetic is simple: position size times the sponsor fee. Add one round trip through the bid/ask spread for the trading cost.
- IBIT or ETHA at 0.25%: $10,000 × 0.0025 = $25 a year.
- MSBT or MSSE at 0.14%: $10,000 × 0.0014 = $14 a year.
- GBTC at 1.50%: $10,000 × 0.015 = $150 a year.
- ETHE at 2.50%: $10,000 × 0.025 = $250 a year.
- Round-trip spread: about $10,000 × 0.0002 = $2 for IBIT versus $10,000 × 0.0005 = $5 for ETHA.
Between the two flagships, the cost gap is $3 per round trip. That is noise. The legacy Grayscale ether trust is the outlier: at 2.50%, ETHE costs $236 a year more than MSSE on the same $10,000.
Which has fallen more: ether or bitcoin?
Ether, by a wide margin. On October 9, 2026, CoinGecko priced ETH at $2,482.80, about 49.8% below its $4,946.05 all-time high. Bitcoin, at $82,508.10, sat about 34.6% below its $126,080 peak. In the past seven days ETH dropped 7.0% while BTC fell 2.2%.
The fund returns tell the same story. iShares reports ETHA’s NAV total return at -10.00% year-to-date and -35.47% over one year, both as of September 30, 2026. IBIT returned -4.30% and -26.80% over the same windows.
Put in dollars, $10,000 in ETHA a year earlier was worth about $6,453 on September 30. The same amount in IBIT was worth about $7,320. That $867 gap dwarfs any fee difference in this comparison.
Why the drawdown gap matters more than the fee
Identical fees mean the choice comes down to the underlying asset. Ether has delivered deeper drawdowns and faster outflows in this cycle. You pay the same 0.25% for a wider ride.
That is not a forecast. Higher volatility cuts both ways, and ether has outrun bitcoin in past rallies. But on the measured record of the last 12 months, the bitcoin fund lost less.
Are Ethereum ETF flows more fragile than Bitcoin ETF flows?
Yes, on two measures. Ether ETFs have a much smaller base, so each redemption moves the category more. And flows are concentrated: ETHA accounts for $12.85 billion of the category’s $13.35 billion cumulative net inflows, per Farside. When ETHA holders leave, the whole category goes red.
Bitcoin has the same concentration, in fact more. IBIT’s cumulative net inflow of $65.71 billion exceeds the $57.16 billion total for all bitcoin funds. That is possible only because GBTC shows $27.94 billion in cumulative net outflows.
Here is the skeptical read. “Record inflows” headlines for either asset mostly measure one BlackRock fund absorbing money from older, pricier products. Net new demand is smaller than the flagship numbers suggest. Grayscale’s ETHE still shows -$5.47 billion in cumulative flows while charging 2.50%, which means holders who stay are paying for inertia or a tax bill they don’t want to trigger.
Where the money moved on October 8
Thursday’s split is instructive. Per Farside, ETHA lost $71.1 million while Fidelity’s FETH took in $5.5 million and Morgan Stanley’s MSSE added $1.3 million. On the bitcoin side, FBTC lost $197.1 million and IBIT just $5.5 million. Outflows rotate between issuers; they rarely hit every fund at once.
Our earlier pieces on the cheapest bitcoin ETF and bitcoin ETF vs self-custody cover the bitcoin-only cost math in more detail.
Ethereum ETF vs Bitcoin ETF: which fits which investor?
The answer depends on three things you can name: how much volatility you accept, whether you want staking income, and how often you trade. A bitcoin ETF fits a single, low-maintenance crypto sleeve. An ether ETF fits a deliberate second position. Staked ether funds fit investors who want yield and accept extra structure.
| Investor profile | Better fit | Measurable reason |
|---|---|---|
| One crypto ETF, buy and hold | Bitcoin ETF | Smaller 12-month loss (-26.80% vs -35.47%), larger asset base |
| Frequent trader or large orders | Bitcoin ETF | 0.02% median spread vs 0.05% |
| Lowest possible fee | Tie | MSBT and MSSE both at 0.14% |
| Wants staking income inside an ETF | Staked ether ETF | Spot ETHA is a separate product from BlackRock’s staked ETHB |
| Already holds ETHE | Review cost | 2.50% fee, 2.36 points above MSSE |
| Tolerates deeper swings for a second crypto asset | Ethereum ETF, sized small | ETH is about 49.8% below its peak vs BTC’s 34.6% |

How do rising Treasury yields affect both funds?
They raise the bar for both. The 10-year Treasury yield hit 5.31%, near its highest since 2002, according to KuCoin’s October 9 market report. Neither ETF pays income, so a risk-free 5% is the opportunity cost of every dollar parked in them.
The same report showed the Nasdaq down 1.25% and the S&P 500 down 0.47% in the October 8 session. Higher-beta assets have tended to take the larger hit when rates climb, and this week ether fit that pattern.
Analysts are framing a range, not a breakout. QCP Capital’s Q4 outlook, cited by The Block, sets a base case of $80,000 to $90,000 for bitcoin and a bear case below $68,000 to $70,000 if oil and further Fed hikes bite.
What to watch next
Three dated events could change the flow picture for both fund families before November.
- October 27, 2026 (tentative): Ethereum’s Glamsterdam upgrade is tentatively set for the Hoodi testnet, per KuCoin. A mainnet date is not confirmed.
- October 27–28, 2026: FOMC meeting, per the Federal Reserve calendar. The decision comes October 28.
- November 4, 2026: Treasury refunding announcement, flagged by QCP Capital as a rate catalyst.
Watch whether the ether outflow streak breaks before the Fed decision. Farside had posted no October 9 figures for ETHA when this article was written.
FAQ
Do Ethereum ETFs and Bitcoin ETFs charge the same fee?
The flagships do. IBIT and ETHA each charge 0.25%. The cheapest funds in each category, MSBT and MSSE, both charge 0.14%, per Farside.
How much did Ethereum ETFs lose in the recent outflow streak?
$641.3 million over eight trading days from September 29 to October 8, 2026, according to Farside. ETHA accounted for $450.0 million.
Which is more liquid, IBIT or ETHA?
IBIT. It had $67.31 billion in net assets on October 7 and a 0.02% median spread, versus $8.68 billion and 0.05% for ETHA.
Has ETHA or IBIT performed better over the past year?
IBIT lost less. Its one-year NAV return was -26.80% versus -35.47% for ETHA, both as of September 30, 2026.
Does ETHA pay staking rewards?
BlackRock offers staked ether exposure through a separate fund, the iShares Staked Ethereum Trust (ETHB). Check each prospectus for how rewards are handled.
Why is Grayscale’s ETHE so expensive?
ETHE charges 2.50%, the highest fee among US spot ether ETFs on Farside’s list. The fund has recorded $5.47 billion in cumulative net outflows.
The bottom line
Fees don’t decide this comparison: both flagships charge 0.25%. Everything else measurable favors the bitcoin ETF. It is 7.8 times larger, trades at a tighter spread, lost 8.67 points less over 12 months, and its outflows are smaller relative to its base.
An ether ETF only makes sense as a deliberate, sized-down second position for someone who accepts deeper drawdowns. If you hold one, the cost lever is fund choice: 0.14% versus 2.50% is the gap that matters, not ETHA versus IBIT.
