The Ethereum blockchain is set to undergo its highly anticipated Shanghai upgrade (Shapella) in just 18 hours—specifically at 6:27:35 AM Taiwan time on April 13, 2025. This pivotal network upgrade will unlock withdrawal functionality for staked ETH, allowing validators to finally withdraw both rewards and principal. While the technical milestone marks a major leap forward for Ethereum’s usability and decentralization, market participants remain divided on its potential price implications.
Institutional voices are split. On one side, JPMorgan analysts warn of looming sell pressure. On the other, Fidelity’s digital asset researchers argue the impact will be negligible. Let’s unpack both perspectives, assess the real risks and opportunities, and explore what this means for ETH holders and the broader crypto market.
What the Shanghai Upgrade Enables
The Shapella upgrade—combining “Shanghai” and “Capella”—introduces critical changes to Ethereum’s consensus layer. Most notably, it enables:
- Full withdrawal of staked ETH and staking rewards
- Flexibility for validators to exit the network after years of lock-in
- Enhanced liquidity across staking ecosystems
Since the Merge in September 2022, over 26 million ETH (roughly $50 billion at current prices) have been locked in staking contracts with no way to withdraw. Post-upgrade, validators can finally access their capital—a long-awaited relief for early adopters and institutional stakers alike.

JPMorgan: Expect Short-Term Sell-Pressure
JPMorgan analysts recently published a report highlighting concerns about post-upgrade market dynamics. Their central argument? A wave of selling could follow.
They estimate that more than 1 million ETH in accumulated staking rewards will become liquid immediately after Shapella goes live. Validators who’ve patiently waited since the Merge may now choose to cash out profits—especially those who staked when ETH was trading at much lower levels.
“If we also factor in potential additional selling pressure from distressed entities holding staked ETH balances, near-term downside risks increase… We expect ETH performance to underperform BTC in the coming weeks.”
This view aligns with traditional financial logic: when illiquid assets suddenly gain liquidity, some portion of holders take profits. JPMorgan also points to historical precedents in equity markets and private investments, where unlocking events often trigger short-term volatility.
Moreover, certain high-profile entities—like bankrupt crypto lenders or over-leveraged funds—may have large amounts of staked ETH on their balance sheets. If these organizations are under financial strain, they might be forced to sell immediately upon withdrawal access.
But does this narrative hold up under deeper scrutiny?
Fidelity: Impact Likely to Be Minimal
Fidelity Digital Assets offers a counterpoint, arguing that the market impact of Shapella will be muted—and possibly even bullish over time.
Their analysis rests on several key observations:
1. Low Operational Costs in PoS
Unlike proof-of-work systems that require expensive mining hardware and electricity, Ethereum’s proof-of-stake model has minimal ongoing costs for validators. This reduces the incentive to sell staking rewards just to cover operational expenses.
2. Many Stakers Are Still in Loss
Before the recent price rebound, a significant portion of staked ETH positions were underwater. Validators who staked during or after The Merge at higher average entry prices may prefer to hold rather than realize losses.
3. LSDs Already Provide Liquidity
Over one-third of all staked ETH is held through liquid staking derivatives (LSDs) like Lido’s stETH or Rocket Pool’s rETH. These tokens are already tradable on decentralized and centralized exchanges, meaning holders have had liquidity options for months—if not years.
As Fidelity notes:
“Much of the economic value behind staked ETH has already been priced into the market via LSDs. True ‘new’ supply hitting the market may be smaller than feared.”
4. Re-Staking and Long-Term Lockups Are Rising
New protocols enabling re-staking—such as EigenLayer—are incentivizing users to lock up their ETH again, even after withdrawal rights are enabled. This creates a structural demand layer that could absorb potential outflows.
Fidelity concludes that while there may be some short-term volatility, the net sell pressure is unlikely to significantly disrupt ETH’s price trajectory.

Market Sentiment Ahead of the Upgrade
Despite institutional disagreements, broader market sentiment appears cautiously optimistic. On-chain data shows:
- Staking participation continues to grow, now representing over 23% of total ETH supply
- Daily net deposits into staking contracts remain positive
- Options markets show elevated call volume, suggesting bullish positioning
Moreover, developer activity around Ethereum remains robust. The ecosystem continues to lead in DeFi TVL, NFT volume, and Layer 2 innovation—providing fundamental support beyond speculative narratives.
Frequently Asked Questions (FAQ)
Q: Will all staked ETH become withdrawable at once?
Yes—after the Shapella upgrade activates, validators can initiate partial or full withdrawals. However, due to network queueing mechanisms, mass exits may experience slight delays depending on validator load.
Q: How much ETH could be sold immediately after the upgrade?
Estimates vary. While over 1 million ETH in rewards are unlockable, analysts believe only a fraction—perhaps 10–20%—may be sold in the first few weeks. Most long-term holders are expected to retain their positions.
Q: Does this mean Ethereum is no longer deflationary?
Not necessarily. While withdrawals add liquidity, Ethereum’s burn mechanism (via EIP-1559) continues to remove base fees from circulation. Net issuance depends on transaction volume and gas prices—making ETH’s monetary policy dynamic rather than purely inflationary or deflationary.
Q: Can I stake ETH now and withdraw immediately after Shapella?
If you stake after the upgrade, you’ll still need to go through the standard activation queue (usually a few days). Once active, you can withdraw at any time—but new stakes won’t benefit from retroactive reward claims.
Q: Could this upgrade trigger a price rally?
While short-term pressure is possible, many see Shapella as a bullish catalyst long-term. Unlocking staking flexibility improves user experience, attracts institutional participation, and strengthens Ethereum’s value proposition as a yield-generating asset.

Final Outlook: A Milestone, Not a Market-Mover
The Shanghai upgrade is undoubtedly a technical triumph for Ethereum—one that enhances decentralization, user sovereignty, and financial flexibility. But as history often shows, major upgrades don’t always lead to dramatic price moves.
Instead of viewing Shapella as an isolated event, it should be seen as part of Ethereum’s broader evolution: transitioning from a simple smart contract platform to a scalable, secure, and sustainable financial infrastructure.
Whether JPMorgan’s caution or Fidelity’s calm prevails in the short term, one thing is clear—Ethereum continues to mature, innovate, and consolidate its position at the heart of the decentralized economy.
For investors, the best strategy may not be timing the market around Shapella, but understanding the long-term shift toward programmable money with real yield—a future that Ethereum is actively building.
