Ethereum Fusaka Upgrade: Could It Spark an 80% ETH Price Rally?

Ethereum's next major evolution is here. The Fusaka upgrade just landed on the mainnet, promising to reshape the network's economics and performance. For traders and holders, one question drowns out the technical chatter: what does this mean for ETH's price?

The Bull Case: Fueling the Fire

Proponents see Fusaka as a direct catalyst. The upgrade slashes base transaction fees and introduces a more predictable fee-burning mechanism. That cuts costs for users and potentially makes ETH more scarce—a classic bullish combo. If network activity surges post-upgrade, the deflationary pressure could tighten supply just as demand picks up. Analysts pointing to the 80% rally target aren't just reading tea leaves; they're betting that improved fundamentals finally get priced in.

The Skeptic's Corner: Upgrade ≠ Guarantee

Not so fast. The crypto market has a PhD in 'buy the rumor, sell the news.' Major upgrades often trigger short-term volatility, not sustained rallies. Furthermore, while Fusaka tackles scalability, it doesn't bypass the broader market's dependence on Bitcoin's momentum and macro sentiment. An 80% move requires more than just a tech improvement—it needs a tidal wave of fresh capital, something no single upgrade can summon on command. Remember, in traditional finance, they'd call this 'pricing in perfection'—and we know how that usually ends.

The Verdict: A Catalyst, Not a Cause

Fusaka makes Ethereum stronger, faster, and more efficient. That builds a better foundation for long-term value. But expecting an automatic 80% surge confuses a necessary condition with a sufficient one. The upgrade provides the spark; the market must provide the fuel. Watch the on-chain data—the real story will be written by adoption, not just by code.

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.It may rise from $3,000 to $4,650.

2.It could reach about $4,740, very close to its previous ATH of $4,953.73.

3.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.
