The approval of a spot Ethereum ETF could be a watershed moment for the crypto market — but will it actually push prices higher, or could it spark another sharp correction?
Historically, financial markets often react unpredictably to major regulatory milestones. While anticipation can drive prices up, the actual event may trigger profit-taking, especially when large holders are involved. In the case of Ethereum, one looming concern stands out: GrayScale’s massive 2.96 million ETH holdings, valued at over $6 billion, could replicate the sell-off seen with its Bitcoin Trust (GBTC) after Bitcoin ETF approval.
The Bitcoin Precedent: When Approval Meant Decline
When the U.S. Securities and Exchange Commission (SEC) approved multiple spot Bitcoin ETFs in early 2025, the market celebrated a historic win for crypto adoption. Institutional validation was finally here — and Bitcoin briefly surged past $49,000.
But the rally didn’t last.
Within weeks, BTC dropped below $39,000, marking an 11.6% decline in just 14 days. What caused this sudden reversal?

Two key factors emerged:
- GrayScale’s GBTC Negative Premium Reversal
Prior to ETF approval, GBTC traded at a steep discount (negative premium) of over 40%. Investors bought in hoping to profit when the trust converted to an ETF and the discount closed. Once conversion happened, that arbitrage opportunity vanished — and so did the incentive to hold. - High Management Fees & Outflows
GBTC charges a 2% annual fee — significantly higher than competing ETFs like those from BlackRock and Fidelity, which charge as low as 0.12%-0.25%. This fee disparity made GBTC less attractive post-conversion, prompting large-scale redemptions.
According to Arkham Intelligence, GrayScale moved nearly 113,000 BTC — worth over $4.5 billion — out of its wallet within days of approval. These outflows likely contributed to downward pressure on Bitcoin’s price.
Could Ethereum Repeat the Same Pattern?
Now, all eyes are on Ethereum.
GrayScale currently holds approximately 2.96 million ETH, representing roughly 1.5% of Ethereum’s total circulating supply. If the SEC approves a spot Ethereum ETF, and ETHE (GrayScale’s Ethereum Trust) follows GBTC’s path, history could repeat itself.
Here’s what might unfold:
- Arbitrage-Driven Selling: Like GBTC, ETHE currently trades at a significant discount. As of recent data from YCharts, ETHE’s negative premium sits at 16.49%.
- Fee Disadvantage: ETHE also carries a 2% management fee — again, much higher than expected fees from future low-cost competitors.
- Conversion Incentive: Once ETHE becomes a spot ETF, investors may rush to redeem shares for ETH and sell into the open market, especially if they bought during the discount phase.
This scenario raises a critical question:
Will Ethereum spot ETF approval act as a “sell-the-news” event?
While long-term fundamentals remain strong, short-term volatility is almost guaranteed if GrayScale begins large-scale ETH withdrawals.
Why the ETHE Discount Could Be a Golden Opportunity
Despite risks, the current ETHE discount presents a strategic entry point for long-term investors.
Consider this:
- Investors who bought GBTC at a 30–40% discount before conversion realized substantial gains once the premium normalized.
- A similar move in ETHE could offer double upside: capital appreciation from narrowing discount and potential ETH price growth.
However, timing is crucial. The window may close quickly once the ETF is approved — so positioning early could make a significant difference.

Still, caution is warranted. Unlike Bitcoin, Ethereum’s ecosystem is more complex — with staking, layer-2 scaling, and ongoing upgrades playing pivotal roles in price dynamics.
The Dencun Upgrade: A Bullish Catalyst on the Horizon
One of the most anticipated developments in 2025 is Ethereum’s Dencun upgrade, set to roll out with EIP-4844 (Proto-Danksharding).
This upgrade aims to dramatically reduce transaction costs on Layer-2 networks like Arbitrum, Optimism, and zkSync by introducing blobs — temporary storage units for off-chain data.
What This Means for ETH:
- Lower L2 Fees: Rollups could see transaction costs drop by 90% or more, making Ethereum far more scalable and user-friendly.
- Increased Adoption: Cheaper transactions mean broader usage — from DeFi to gaming and social apps.
- Higher Demand for ETH: As network activity grows, so does demand for gas and staking — both of which support ETH’s value.
Market sentiment already reflects optimism around Dencun. Analysts believe this upgrade alone could propel ETH to new all-time highs — if macroeconomic conditions cooperate.
Key Factors Influencing Post-ETF Price Action
Beyond GrayScale and technical upgrades, several forces will shape Ethereum’s trajectory post-ETF approval:
1. Institutional Inflows vs. Outflows
Will new ETFs attract enough institutional capital to offset potential ETHE redemptions? The answer depends on:
- Fee competitiveness
- Custodial solutions
- Tax efficiency
2. Regulatory Clarity
SEC approval of an Ethereum ETF signals clearer regulatory treatment — possibly reinforcing ETH’s status as a commodity rather than a security.
3. Macro Environment
Interest rates, inflation trends, and risk appetite in traditional markets will heavily influence crypto flows in 2025.
4. Staking Yields
Over 27% of ETH supply is staked. With average yields around 3–5%, ETH offers income-generating potential rare in digital assets — adding a floor to selling pressure.
Frequently Asked Questions (FAQ)
Q: Has the SEC approved a spot Ethereum ETF yet?
A: As of mid-2025, no spot Ethereum ETF has been officially approved. However, multiple applications are under review, and market expectations remain high for approval later this year.
Q: Why did GBTC’s price drop after ETF approval?
A: The decline followed massive outflows due to high fees and arbitrageurs cashing in on the closure of GBTC’s long-standing discount to net asset value.
Q: Is ETHE a good buy now?
A: For long-term investors, ETHE’s current 16.5% discount may offer value — especially if an ETF conversion occurs. But it carries risks similar to GBTC, including fee disadvantages and potential sell-offs.
Q: How does the Dencun upgrade affect ETH price?
A: By slashing Layer-2 costs via EIP-4844, Dencun could accelerate Ethereum adoption, increasing network usage and demand for ETH — bullish in both short and long term.
Q: Could GrayScale dump 3 million ETH at once?
A: Unlikely. Sales would be gradual due to market impact concerns. However, even slow outflows could weigh on price if not offset by strong inflows elsewhere.
Q: What happens to ETHE after an ETF conversion?
A: Similar to GBTC, ETHE would likely transition into a regulated spot ETF. Existing shareholders can expect redemption options, but may face tax implications depending on jurisdiction.

Final Thoughts: Prepare for Volatility, Focus on Fundamentals
The potential approval of a spot Ethereum ETF is both exciting and risky. While it marks a milestone in crypto legitimacy, it also opens the door to short-term turbulence — especially with GrayScale’s massive holdings at play.
History suggests that “buying the rumor, selling the news” could apply here. Yet unlike Bitcoin, Ethereum has stronger utility drivers — from staking rewards to upcoming scalability upgrades like Dencun.
For investors, the key is balance:
- Recognize the risk of post-approval sell-offs
- Leverage strategic opportunities like ETHE’s current discount
- Stay aligned with long-term network developments
Ultimately, while GrayScale’s 3 million ETH loom large, they don’t define Ethereum’s future. The real story lies in adoption, innovation, and how well the network continues to evolve.
As always in crypto: expect volatility, plan accordingly, and invest with conviction.
