Ethereum Fusaka Upgrade Impact on ETH Price: Is 80% Rally Next?

1 Day To Ethereum Fusaka Upgrade: Will ETH Rally 80% and Beat Pectra?

The countdown has started. Only one day is left before the Ethereum Fusaka Upgrade goes live on December 3, 2025 at 21:49 UTC. This is one of the biggest events for the altcoin this year, and the crypto community is waiting with huge excitement. 

As per the latest Ethereum Fusaka news, it has already passed testing on Holešky, Sepolia, and Hoodi, and the network is ready for mainnet activation. A live watch party by ethStaker will begin at 21:20 UTC.

This upgrade is important because many traders believe tomorrow can change the asset’s speed, fees, and adoption in a major way. Let’s now uncover what traders should know, what will be the ETH fusaka price impact and prediction going forward.

Why Big Finance Is Watching the Ethereum Fusaka Upgrade Closely

This week, Amundi, a massive $2.75 trillion asset manager, launched a tokenized money-market fund on the asset. Last week, Fidelity ($6 trillion AUM) said the Fusaka Upgrade eth is “pivotal” for altcoin’s future.

This signals a clear trend: large financial institutions are moving onchain. With RWAs (Real World Assets), tokenized funds, and enterprise adoption rising, many people believe Fusaka Upgrade Ethereum price impact will be huge once the mainnet goes live.

Key Points Every Trader Should Know Before December 3

It is a major scaling and performance revision. It will make the asset faster, cheaper, and easier for users and developers. The strongest feature is PeerDAS, which increases data capacity by 8× and helps reduce L2 fees below $0.01.

Main Features:

• PeerDAS → 8× data scaling

• L2 transaction fees drop to under $0.01

• Gas limit may rise from 45M → ~60M

• Blob Base Fee Fix stops blob fees from dropping too low

• History expiry removes old data and improves node performance

• MODEXP security update prevents heavy transactions from slowing the chain

• Max transaction gas cap (16,777,216 gas) protects block space

• Block size cap (~8 MiB) for better network health

• P-256 passkeys bring password-free wallets

• CLZ opcode improves smart contract efficiency

All these changes directly support the upcoming mainnet, because the network now becomes more scalable and secure, fueling questions like, will it fuel ETH rally or make crash go deeper? 

What’s The Market Trend? Rally or Crash Analysis

On the TradingView chart, the token recently fell toward $2,720, then bounced back to around $2,812, forming a higher low, and higher highs pattern.  As per my Ethereum price analysis being a crypto expert, it is often an early sign of trend reversal.

• MACD turned bullish, showing early strength

• Key resistance: $2,880–$2,900

• Important support: $2,750

If token breaks above $2,900 on mainnet, the next major rally may target higher levels. 

Upgrade Effect: Ethereum Price Prediction December 2025 and Beyond

After the last major Pectra update, the asset jumped +58%. Analyst Merlijn believes Ethereum Fusaka upgrade may bring an even stronger reaction because it improves throughput, security, L2 fees, and enterprise support.

Here are the three price scenarios based on the above chart:

1. Conservative Move (+40% to +55%): It may rise from $3,000 to $4,650.

2. Same as Pectra (+58%): It could reach about $4,740, very close to its previous ATH of $4,953.73.

3. Stronger Reaction (+65% to +80%): With cheaper fees, RWAs, and institutional interest, it may hit $4,950 to $5,400 and enter new all-time highs.

Final Outlook: Last Chance Before a Major Pump

Everything from technology, fees, speed, RWAs, institutional interest, and whale activity, is aligning around the Ethereum Fusaka Upgrade going live tomorrow, December 3, 2025. 

With 8× scaling, L2 fees, and enterprise-grade improvements, many cryptocurrency top analysts believe ETH rally could see a 40% to 80% price jump after activation.
