BlackRock to skim 18% of staked Ethereum ETF rewards from investors — and ETHB exits could take weeks
BlackRock has sharpened the staking posture for its iShares Staked Ethereum Trust ETF (ETHB), outlining a plan to preserve most of the fund’s ETH staked and incomes rewards fairly than held in custody.
In its newest amended filing, the sponsor stated that below regular market circumstances, it might search to preserve 70% to 95% of the fund’s ETH staked.
The the rest would sit in what it calls a Liquidity Sleeve, an unstaked buffer designed to deal with day-to-day creations, redemptions, and bills.
The change clarifies the product’s intent. ETHB packages spot ETH publicity into an exchange-traded fund whereas additionally incorporating Ethereum staking throughout the similar ETF construction.
By embedding staking, the product strikes nearer to a carry-oriented technique wherein yield kinds a core part of anticipated returns.
Staking ambition meets ETF liquidity math
ETHB is structured to situation and redeem shares in 40,000 share baskets.
The belief primarily holds ETH in custody and makes use of a main execution agent, Coinbase, to facilitate staking by means of permitted validator preparations.
The purpose is to preserve the bulk of ether working whereas preserving the fundamental ETF promise, shares that may be created and redeemed in a predictable approach.
That promise turns into harder when most of the portfolio is staked. Staked EtherEUM remains to be an on-chain asset, however the course of of placing it to work and pulling it again out runs on Ethereum’s guidelines, not Wall Street’s settlement expectations.
The submitting addresses that rigidity by formalizing a liquidity plan alongside the 95% staking goal.
The sponsor stated it intends to keep a Liquidity Sleeve of 5%-30% of unstaked ETH, sizing it dynamically based mostly on anticipated flows and community situations.
If the buffer is depleted throughout heavy redemptions, BlackRock contemplates utilizing money in lieu of redemptions, and it additionally describes the chance of delayed settlement for in-kind redemptions in careworn eventualities.
That is a technical level with a sensible that means for arbitrage. Staking introduces a liquidity clock into the mechanism meant to preserve an ETF’s market value aligned with the worth of its holdings.
For investors used to considering of ETFs as clear plumbing, the submitting is a reminder that this product is attempting to do two jobs without delay. It should behave like an ETF, even because it operates a staking e book that retains most of its ETH deployed.
The queue turns staking into time to yield
Ethereum staking isn’t instantaneous. Validators enter and exit by means of rate-limited queues which might be designed to shield consensus stability.
ETHB’s submitting makes that protocol design a headline danger issue as a result of it immediately impacts when the fund can start incomes rewards on newly deposited ether.
The prospectus notes that staking activation requires becoming a member of an activation queue and then ready a further 4 epochs (about 25 minutes) earlier than rewards start accruing. It additionally lists a most activation throughput of roughly 57,600 ETH per day.
As of Feb. 5, 2026, the submitting cited an activation queue of roughly 4 million ETH, which might take roughly 70 days.
If ETHB experiences a surge of inflows and makes an attempt to stake the majority of newly deposited tokens, a significant portion of the belongings could stay in line for weeks earlier than producing staking rewards.
That delay is a cloth structural characteristic for a product designed to preserve 70% to 95% of its belongings staked. It introduces a ramp-up interval wherein the fund is allotted for staking however has but to generate staking rewards.
The doc additionally spells out the mechanics on the way in which out.
It outlines exit and withdrawal steps that embody an exit delay, a withdrawability delay of roughly 27 hours, and a withdrawal sweep that may take roughly 7 to 10 days. It provides that the method can take weeks to months in periods of congestion.
Those constraints matter most within the eventualities ETFs are constructed to face up to: quick value strikes and shifting flows.
Investors should buy and promote shares all through the day, however the fund’s capacity to modify its stake place or restore its liquidity sleeve after massive flows is constrained by the community’s queues and timing.
The price of turning protocol yield right into a regulated wrapper
ETHB’s submitting additionally makes the economics of staking inside an ETF specific.
The belief can pay a Staking Fee, which incorporates remuneration for the sponsor and a share for the prime execution agent, together with quantities payable to staking suppliers.
As of the prospectus date, the submitting said that these parts represent 18% of the gross Staking Consideration, with the belief retaining the rest.
Alongside that staking payment, ETHB fees a conventional sponsor payment of 0.25% yearly on web asset worth, with a 12-month waiver to 0.12% for the primary $2.5 billion of belief belongings.
For crypto native investors, that payment stack is a central query.
Staking returns on Ethereum are not fixed and can differ with community participation, charges, and the broader staking combine.
A regulated wrapper could make staking accessible by means of acquainted brokerage rails, however it could possibly additionally scale back the portion of rewards that in the end reaches shareholders, even earlier than contemplating any delay brought on by the activation queue.
ETHB would pull in tens of millions in income for BlackRock
The submitting’s 95% staking ambition invitations an investor query that’s widespread in conventional finance, what does this imply for payment income if the product scales.
BlackRock’s spot ETH ETF, ETHA, gives a reference level. This is the largest spot Ethereum fund.
As of Feb. 13, 2026, BlackRock’s iShares product web page listed ETHA with $6.58 billion in web belongings and 425.4 million shares excellent.
It additionally listed a Basket ETH Amount of 302.14 ETH per 40,000 share basket. Those figures indicate ETHA holds about 3.21 million ETH.
If ETHB have been half as profitable as ETHA by dimension, that might translate to roughly $3.29 billion in belongings below administration and about 1.61 million ETH held.
Using the mechanics described within the ETHB submitting, and retaining the assumptions specific, the potential staking economics might be sketched as a spread fairly than a single level.
Assume the fund maintains an aggressive posture, with 95% of its ETH staked.
For staking yield, use two public reference factors that bracket current situations, Coinbase’s estimated ETH staking reward fee of about 1.89% APY and ValidatorQueue’s community APR snapshot of about 2.84%.
We will use the prospectus’s ETH value reference of $1,918 because the conversion baseline.
Under these assumptions, a half-ETHA-scale ETHB could generate gross staking rewards, in regular state, of about 28,800 ETH per yr at 1.89%, or about 43,300 ETH per yr at 2.84%.
Apply the submitting’s 18% skim pool, and the combination quantity carved out for the sponsor, the prime execution agent, and staking suppliers could be about 5,200 ETH per yr at 1.89%, or about 7,800 ETH per yr at 2.84%.
Using the $1,918 reference, these figures correspond to about $10.0 million and about $15.0 million.
Meanwhile, calculating the sponsor payment is less complicated.
On about $3.29 billion of belongings, a 0.25% annualized sponsor payment implies about $8.2 million per yr after the waiver interval. In yr one, if the product totally qualifies for the 0.12% waiver on the primary $2.5 billion, the sponsor payment could be roughly $5 million.
Taken collectively, a steady-state income goal at half the ETHA scale might be framed as roughly $11 million to $20 million per yr, combining the sponsor payment with an assumed share of the staking skim pool.
A brand new suggestions loop between ETF flows and the community
BlackRock’s ETHB submitting factors to a second-order impact that could matter if staking ETFs develop.
If a number of US-listed funds start staking at scale, Ethereum’s activation queue becomes a market variable alongside ether’s value and ETF circulate knowledge.
ValidatorQueue’s snapshot confirmed about 3.9 million ETH within the queue, with an estimated 67-day entry wait and an APR of about 2.84%.
In that setting, the connection between demand and yield turns into extra mechanical. Bigger ETF inflows that chase staking rewards can lengthen the queue, delaying yield realization.
Over time, bigger staking participation may also put stress on yields, as a result of the identical reward circulate is distributed throughout a bigger staked base.
The reverse can occur in risk-off intervals. If exits rise, entry queues can shorten, however the identical situations can stress ETF liquidity.
The submitting’s dialogue of cash-in-lieu redemptions and delayed settlement underscores that when investors prioritize redemption mechanics, community congestion and withdrawal timing can change into extra consequential.
BlackRock’s plan to stake up to 95% of ETHB’s belongings is due to this fact much less a easy yield add-on and extra a shift in how investors may have to consider ETH publicity in an ETF wrapper.
