The buzz around Ethereum staking ETFs is heating up as we head into October 2025, with regulatory green lights and product launches signaling a potential breakthrough for institutional crypto adoption.
While the SEC has delayed several key decisions on staking features for major Ethereum ETFs—pushing deadlines to mid-to-late October— October 18–23 for filings like 21Shares Core Ethereum ETF with staking, and October 30 for BlackRock’s iShares Ethereum Trust—the landscape is shifting positively.
This comes after a pattern of extensions rather than outright rejections, with prediction markets like Polymarket pegging approval odds for related assets (e.g., Litecoin and XRP ETFs) above 75%.

A major milestone already hit in late September: REX-Osprey™ launched the first U.S.-listed Ethereum staking ETF (ESK: REX-Osprey™ ETH + Staking ETF) on September 25, 2025, under the 1940 Act structure.
This fund offers spot ETH exposure plus monthly staking rewards, bypassing some SEC hurdles via a Cayman Islands subsidiary for staking operations. It follows their Solana staking ETF (SSK) debut in July, which has amassed over $300M in assets.
Grayscale Ethereum Trust (ETHE) shareholders also voted overwhelmingly over 90% approval on September 26 to amend their trust for ETH staking, paving the way for implementation pending regulatory nods.
Staking could add ~3% yield on top of existing basis trades already ~7% annualized, potentially driving massive inflows and reshaping ETH demand—possibly rivaling Bitcoin ETFs.
With ETH trading around $4,100 in September amid spot ETF inflows, approvals could catalyze an “altcoin season” by easing access to yield without direct node management.
Leveraged BMNR ETF Hits the Ground Running
BitMine Immersion Technologies (BMNR), the Ethereum-holding powerhouse with 2.4M ETH ~$9.6B at current prices, is making waves through its new leveraged ETF wrapper.
T-Rex’s 2X BitMine ETF (BMNU), which delivers 2x daily leveraged exposure to BMNR stock, exploded onto the scene on September 26, 2025, with $32M in first-day volume—ranking as the third-best ETF debut of the year among ~650 launches.
Over its first three trading days through September 29, BMNU racked up approximately $200M in cumulative volume, fueled by retail and institutional hunger for amplified crypto-tied plays.
This outperforms most 2025 launches, trailing only niche hits like the XRP ETF and Dan Ives-themed fund. BMNR itself saw massive liquidity, with average daily volumes exceeding 47M shares and a 52-week range from $3.92 to $161, reflecting its role as a “MicroStrategy for ETH” accumulator aiming for 5% of total ETH supply.
The surge underscores broader trends: Leveraged single-stock ETFs on crypto-adjacent firms are drawing speculators seeking volatility without direct coin custody. BMNU’s structure 2x daily reset amplifies BMNR’s moves, but remember the risks—compounding can erode returns over time, especially in choppy markets.
If BMNR hits its ETH hoarding goals, this could be just the start. By enabling passive yield generation typically 2.5–3.5% annually alongside spot ETH exposure, these products address a key barrier: the complexity of direct staking for institutions.
This isn’t just incremental; it could catalyze a feedback loop of demand, yield enhancement, and network security, with ripple effects across markets and regulation. Analysts forecast staking could supercharge the existing basis trade spot ETH ETFs vs. futures, yielding 7% annualized by layering on staking rewards, potentially drawing billions in new capital.
In late September, 10 wallets scooped up 210K ETH ($863M) via OTC desks like Kraken and Galaxy Digital, avoiding slippage and hinting at ETF positioning. Grayscale’s 90%+ shareholder approval for staking its 1.5M ETH holdings worth ~$6B on September 26 further underscores this, positioning it as a potential first-mover among spot ETFs.
If BlackRock, Fidelity, and 21Shares get the green light by October 30, inflows could rival or exceed Bitcoin ETFs’ $140B+ AUM, pushing ETH toward $7,500 by year-end per Standard Chartered forecasts—a 55%+ rally from September’s $4,100 highs.
Staking ETFs would make ETH a more compelling yield play than non-staking peers, attracting conservative allocators like pensions and endowments. This could reduce ETH’s volatility premium while amplifying upside during bull runs, as seen with Solana’s SSK ETF amassing $300M AUM since July.
Prediction markets like Polymarket now price XRP/Litecoin ETF odds at 75%+, suggesting broader altcoin momentum if ETH staking succeeds. With 29.45% of ETH supply already staked (35.3M ETH), ETF inflows could lock up more validators, slashing exit queues currently 910K ETH, ~$3.9B and stabilizing the Proof-of-Stake consensus.
However, the 9–50 day unbonding period poses liquidity risks for ETFs, requiring custodians like Coinbase to buffer reserves—potentially introducing minor sell pressure during high-activity periods.
Delays to October reflect scrutiny on custody, manipulation, and reward classification, but the pattern favors extensions over denials—echoing Bitcoin’s path. A Trump-era pro-crypto tilt could accelerate approvals, legitimizing staking as a commodity feature and paving for Solana/XRP variants.
Rejection, though, might cap ETH’s yield appeal, prolonging outflows like Fidelity’s $272M FETH dip in August. Centralization fears loom if ETFs control >50% of stake via a validator cartel, risking attacks or fraud. ETH price could dip short-term on uncertainty, as seen post-delays.
BMNR’s stock 52-week: $3.92–$161 saw 47M+ daily shares traded, trading at NAV premiums that could balloon with ETH’s rally—positioning BMNU as a retail/institutional bridge to crypto volatility.
Peter Thiel’s Founders Fund staking 9.1% 5M shares in July validates BMNR’s model, mirroring MSTR’s BTC playbook. The ETF could fuel BMNR’s ETH buys +135K ETH in August, tightening supply and pressuring prices upward—especially if staking ETFs approve, synergizing with BMNR’s yield-agnostic hoarding.
BMNU democratizes 2x bets on ETH treasuries, drawing traders eyeing AI/crypto convergence via holdings like CoreWeave. It outperforms vanilla ETH ETFs for short-term conviction, but compounding erodes long holds in sideways markets—ideal for directional swings.
Fundstrat’s Tom Lee envisions ETH treasury firms (BMNR, SBET, BTCC) merging into a “super-entity,” amplifying ETF flows and creating a $50B+ ETH vehicle. Granny Shots ETF ($GRNY) hitting $1B AUM in six months shows precedent for niche leveraged success.
BMNR risks flipping to NAV discounts if ETH corrects, crushing BMNU’s 2x leverage a 10% ETH drop could mean 20%+ ETF loss, plus decay. High volume masks this, but dilution from raises remains a drag.
