Ethereum (ETH) Price Prediction: Analysts Forecast a Monster Rally Following the Fusaka Upgrade Launch

Ethereum’s next major upgrade, Fusaka, isn't just another protocol tweak—it's the catalyst analysts claim could detonate a historic price surge.

The Upgrade Engine

Fusaka targets the blockchain's perennial pain points: transaction fees and finality speed. By implementing a refined data-sharding model and optimizing consensus mechanisms, the upgrade slashes network congestion and bypasses previous scalability ceilings. It’s a technical overhaul designed for one outcome: superior network performance.

Market Mechanics in Play

This isn't speculative hopium. The upgrade directly impacts Ethereum's fundamental value proposition. Enhanced throughput and lower costs attract more developers and high-volume applications—driving real utility and demand for ETH. Analysts point to this surge in network activity as the primary fuel for a potential monster rally, where price follows proven utility. Of course, in crypto, sometimes the rally happens first and the utility scrambles to catch up—a classic case of the tail wagging the dog.

The Bottom Line

Fusaka shifts Ethereum from a 'proof-of-concept' powerhouse to a streamlined execution layer. If it delivers, the stage is set. Watch the upgrade, watch the metrics, and watch the charts. The next leg up might just be built on code.

TLDR

• Ethereum’s Fusaka upgrade launched on December 3, 2025, introducing PeerDAS technology that reduces node storage requirements by 80% while enabling up to 8x scalability for Layer 2 rollups.
• The upgrade caps individual transactions at 16.8 million gas to prevent network congestion and implements improved blob fee mechanisms tied to actual network demand.
• PeerDAS allows nodes to store only one-eighth of blob data while maintaining full data availability, directly reducing costs for Layer 2 solutions.
• Fusaka adds native support for passkey authentication through secp256r1 signatures, eliminating seed phrase requirements for institutional users.
• One analyst predicts Ethereum could rally over 100% following the upgrade, though experts note Fusaka focuses more on infrastructure than user-facing features compared to May’s Pectra fork.

Ethereum activated its Fusaka upgrade on December 3, 2025, at 21:49 UTC. The upgrade introduces Peer Data Availability Sampling, known as PeerDAS, which changes how the network handles data storage and processing.

PeerDAS allows network nodes to store just one-eighth of blob data. This reduces storage requirements by approximately 80%. The technology maintains full data availability through distributed sampling across the network.

The upgrade enables theoretical scalability improvements of up to 8x for Layer 2 rollups. These rollups depend on ethereum to publish transaction data on-chain. Lower storage demands mean rollups can process more transactions at potentially lower costs.

Fusaka represents Ethereum’s second major network enhancement in 2025. The previous Pectra fork launched in May and triggered a 29% price increase in ETH.

The hard fork merges two separate improvements. The Osaka execution LAYER upgrade combines with the Fulu consensus layer update. Together they deliver changes focused on scalability, security, and network stability.

Gas Caps and Fee Improvements

Ethereum Improvement Proposal 7825 caps each transaction at 16,777,216 gas units, roughly 16.8 million. This prevents any single transaction from consuming an entire block. The cap helps maintain network stability during high traffic periods.

In Fusaka, Ethereum gets several upgrades to protect it against coordinated attacks.

One is EIP-7825 – which introduces a ~16.7M gas limit on transactions to prevent a single massive transaction taking up an entire block.

Most regular users won’t notice the change. Teams running complex smart contracts will need to adjust their code to stay within the new limit.

The upgrade also refines how blob fees work. EIP-7918 ties blob pricing to actual network congestion. This protects the network’s economic security while making costs more predictable for developers.

Node operators are preparing for a higher block gas target of 60 million. This allows the network to handle more overall activity.

Authentication and Security Updates

Fusaka adds native support for secp256r1 curve cryptography. This enables passkey-style logins using Apple Secure Enclave and Android Keystore. Users can authenticate without managing seed phrases.

Sharplink CEO Joseph Charom described Fusaka as “a massive milestone for Ethereum and its institutional adoption journey.” The passkey feature could accelerate institutional use by removing technical barriers to entry.

The upgrade introduces Blob-Parameter-Only forks. These allow developers to adjust blob capacity targets and limits without requiring a full network hard fork. Ethereum can now respond faster to changing rollup demand.

The Ethereum Foundation documentation explains that PeerDAS lets nodes verify data availability by sampling small data portions across the network. This reduces bandwidth requirements while supporting greater blob capacity.

The network will add capacity in stages. More changes are scheduled for December 9 and January 7. The phased approach helps developers adjust gradually.

Market Reaction and Price Outlook

One crypto analyst posted a bullish forecast following the upgrade announcement. He expects ethereum price to climb more than 100% and called the setup “the biggest ETH outperformance this cycle has seen.”

Ethereum will surge more than 100% after the Fusaka update

The next week's will be the biggest ETH outperformance this cycle has seen, and this cycle will top with new ETH ATH's like I've been saying for 2 years now.

The analyst’s chart shows Ethereum breaking out of a descending channel that controlled price movement for weeks. The token now trades above the $3,000 level, which has flipped from resistance to support.

He wrote that “Q1 2026 is our time” and encouraged heavy positioning across the Ethereum ecosystem. He predicts the cycle will end with new all-time highs for ETH.

Other analysts remain cautious about drawing direct comparisons to Pectra. That May upgrade coincided with broader market tailwinds, including a US-UK trade deal. Fusaka’s impact may depend more on sustained Layer 2 growth than immediate speculation.

Core developers say the update sets the stage for cheaper scaling. Teams running Ethereum-based services have been told to update their software and test changes on test networks.

Ethereum currently holds above the $3,000 support zone with sideways price movement. The chart shows rising demand and buyers stepping in on small dips. A clear break above the next resistance area could trigger faster gains.
