How High Could Ethereum Price Go When Fusaka Launches? History Gives a Clue

ETH-USD +5.12%

Key Takeaways

• Ethereum’s Fusaka upgrade launches Dec. 3.

• Past upgrades have triggered rallies.

• Analysts remain unconvinced.

Ethereum is preparing to implement its next major network upgrade, known as Fusaka, on Dec. 3, 2025, a shift that developers say will boost blockchain capacity and lower transaction costs.

The launch comes at a pivotal moment for Ethereum, with ETH’s price hovering near key technical levels that analysts say will decide whether we see renewed strength or further downturn.

Fusaka Overview

Ethereum’s network overhaul, known as the Fusaka upgrade, is scheduled to go live on Dec. 3, 2025, marking a significant development in the blockchain’s long-term scaling roadmap.

One of the main additions will be increasing the block gas limit from approximately 45 million to 60 million, thereby expanding transaction capacity per block.

It also introduces Peer Data Availability Sampling, which allows validators to verify data by sampling portions rather than downloading full blobs.

Additional changes target Layer-2 rollup efficiency, aiming to make decentralized applications cheaper and faster to use.

The upgrade, which is designed to make the network faster and cheaper, is being watched closely to see how it will affect Ethereum’s price.

Upgrades Have Caused Rallies Before

Earlier in 2025, the network’s May Pectra upgrade caused a price increase of over 30% within days.

While market conditions differ today, Fusaka is seen as a more substantial infrastructure improvement, potentially signaling another rally.

The upgrade will appeal to institutional investors such as BitMine, which announced on Monday it had bought another 96,798 ETH ahead of the upgrade.

As of the time of reporting, Ethereum traded at around $2,839.

Tom Lee’s Bullish on Ethereum, But Cautious

Lee warned that while Ethereum could dip to around $2,500 in the near term, he believes a potential surge of between $7,000 and $9,000 by early 2026 is likely.

Despite the crypto market continuing to bleed, Lee has remained bullish on his outlook.

“In the near-term, there is downside to $2,500, but that is minor compared to the upside,” he said.

Current Market Conditions

Analysts say ETH is positioned at a crucial level ahead of the December upgrade.

According to CCN analyst Valdrin Tahiri, ETH recently broke out of a descending wedge pattern but failed to sustain the rally. It is now attempting to validate the wedge as support.

A successful retest could open the door to a move toward $3,500, a resistance zone defined by long-term horizontal levels and the 0.382 Fibonacci retracement.

However, Tahiri noted that this rally “seems unlikely based on Ethereum’s long-term readings.”

“Traders should be prepared for more volatility unless ETH reclaims higher resistance levels with conviction,” he wrote.
