In the world of cryptocurrency, subtle yet powerful forces often shape market movements beneath the surface. One such force emerged after Ethereum’s Shanghai upgrade—an event that quietly reshaped the dynamics of ETH staking, options trading, and volatility. This shift has given rise to a mysterious market participant whose actions are now central to understanding ETH’s price behavior.
The Hidden Current: Ethereum’s Shanghai Upgrade Impact
Three months ago, a historic transformation began in the Ethereum ecosystem—the ability to withdraw staked ETH post-Shanghai upgrade. Like an oceanic undercurrent redistributing heat across the globe, this change triggered a chain reaction in market structure.
Staking activity surged by approximately 38% following the upgrade, as users gained liquidity for their previously locked assets. But beyond simple capital movement, a deeper structural shift occurred—one reflected in derivatives markets, particularly options trading on platforms like Deribit.
This change didn’t just affect supply and demand for ETH; it altered the very mechanics of volatility pricing.

Why Is ETH Volatility Compressing?
At first glance, Ethereum’s price hasn’t become dramatically less volatile. However, implied volatility—the market’s forecast of future price swings—has been consistently suppressed. This phenomenon is captured by the Deribit Volatility Index (DVOL), which shows a steady decline in ETH’s expected volatility.
According to Joe Kruyer of Paradigm, a single large-scale player appears to be behind this trend:
"A large systematic options trader rolled 90,000 March-expiry $1,800 calls into June-expiry $1,800 calls, injecting around 125,000 net vega into the market, alleviating the natural shortage of upside buyers in ETH."
To break this down: when an entity sells call options, they’re effectively betting against sharp upward moves in price—and against rising volatility. In options terminology, this is known as being short vega. Vega measures sensitivity to changes in implied volatility. Selling calls makes you short vega; buying them makes you long.
By selling tens of thousands of call options at key strike prices—such as $1,800 and $2,200—the entity floods the market with volatility supply. This dampens premium prices and suppresses overall implied volatility.
Further evidence points to ongoing activity:
"Post-Shanghai, there was significant selling in June/September $2,200 calls (net -200k vega), followed by additional pressure from September/December $2,300 calls (-45k vega) and mixed maturities (-45k vega)."
This consistent pattern suggests a deliberate, repeatable strategy: sell calls when volatility dips, accumulate premium income, and maintain a short-volatility posture across multiple expiries.
When volatility does rise or prices approach sold strikes, the seller must hedge—often by selling ETH futures or buying puts—creating downward pressure on price and further reinforcing low-volatility conditions.
Yet recently, signs of reversal emerged. Over one weekend, the same entity reportedly bought back 100,000 June contracts, signaling a potential unwind. Still, open interest remains high—especially at the $1,800 strike—indicating that the position isn’t fully closed.
"Q2 appears to be witnessing major microstructural changes in crypto options markets."
What’s Driving This Behavior?
The timing is no coincidence. The Shanghai upgrade didn’t just unlock staked ETH—it unlocked new financial engineering possibilities.
As Paradigm notes:
"The surge in ETH volatility supply stems from two factors: Ethereum’s transition to proof-of-stake and the implementation of the Shanghai upgrade. Withdrawals enabled a significant increase in staking activities aimed at harvesting validator yields."
This leads to a compelling hypothesis: a large staking entity is using its ETH holdings as collateral to generate additional yield through options writing.
Imagine a validator with hundreds of thousands of ETH. They earn ~3–5% annually from staking rewards. But by selling call options against their holdings (a covered call strategy), they can boost returns—especially in a low-volatility environment where premiums are still attractive.
But here’s the catch: staked ETH cannot be moved instantly. To execute such trades off-chain, there may be special arrangements with exchanges like Deribit to avoid automatic liquidation during volatile spikes.
"We speculate unique arrangements exist between underwriters and Deribit to prevent auto-liquidation during spot rallies or volatility surges."
Could this entity be one of the major Liquid Staking Derivatives (LSD) providers? Candidates include stETH (Lido), cbETH (Coinbase), rETH (Rocket Pool), and frxETH (Frax)—all representing large pools of staked ETH.
On-chain analysis reveals no single vault or protocol holding enough LSD tokens to match the scale of these trades. There's no $100M Ribbon Finance-style vault dominating the landscape. This implies the operations may be off-chain, possibly managed directly by centralized custodians or institutional validators.

Who Is This Mysterious Entity?
While definitive identification remains speculative, all evidence points toward a large validator or staking pool operator—one with deep access to staked ETH and direct relationships with derivatives exchanges.
Key indicators:
- Massive, repeated vega-selling across multiple expiries
- Timing aligned with Shanghai upgrade and increased staking
- Off-chain execution suggesting institutional infrastructure
- Lack of on-chain footprint despite enormous market impact
Such an entity benefits from:
- Scale: Control over hundreds of thousands of ETH
- Stability: Long-term holding horizon due to staking commitments
- Market Access: Direct integration with options desks and margin systems
Their influence extends beyond volatility suppression. By systematically reducing upside exposure via call sales, they indirectly cap price momentum—creating a feedback loop where rising prices trigger hedging sales, dampening rallies.
Moreover, their risk isn’t limited to spot ETH. Additional revenue streams could come from MEV (Maximal Extractable Value), node operation fees, or even secondary DeFi strategies—making their total upside exposure broader than pure price appreciation.
FAQ: Understanding the ETH Market Shift
Q: What is vega in crypto options?
A: Vega measures how much an option’s price changes in response to shifts in implied volatility. Being short vega means you profit when volatility decreases.
Q: How does selling call options reduce volatility?
A: Large-scale call selling increases supply in the options market, lowering premiums and implied volatility. It also forces hedging behavior that stabilizes price movements.
Q: Could this strategy backfire?
A: Yes—if ETH surges past sold strike prices without hedging, losses could mount. High leverage or margin calls could trigger forced selling, amplifying downturns.
Q: Is this legal or manipulative?
A: These are standard derivatives strategies used globally. While influential, they operate within exchange rules and do not constitute market manipulation if transparently executed.
Q: Can retail traders replicate this?
A: Partially—through covered calls or yield vaults—but without institutional scale or margin advantages, impact and returns are far smaller.
Q: Will this continue in 2025?
A: As long as staking remains profitable and volatility stays moderate, such strategies are likely to persist—and possibly expand.

Final Thoughts: A New Era of Crypto Market Structure
The Shanghai upgrade did more than restore liquidity—it unlocked a new layer of financial engineering in Ethereum’s ecosystem. What we’re seeing isn’t just technical evolution; it’s the emergence of institutional-grade market-making behavior driven by staking economics.
This mysterious entity may remain unnamed, but its fingerprint is clear across options flows, volatility curves, and price action. As their position grows, so does their influence on ETH’s trajectory.
For investors and traders alike, understanding these hidden currents is no longer optional—it's essential for navigating the next phase of crypto markets.
