Ethereum (ETH 9.18%) is approaching what might be another one of its glowing moments. Its next network upgrade, called Fusaka, is so far on track for a launch on Dec. 3, building on the successes of this spring's upgrade called Pectra.
Much like with the features included in Pectra, Fusaka is very likely to be a catalyst for higher prices, and durably so. Here's what you need to know about it, and why it's going to be an instrumental part of the chain's future.

This network is scaling up even more
Pectra shipped in early May, and it bundled a handful of improvements together. Those improvements increased the usability of its wallets and increased the chain's ability to process transactions cheaply at scale, which has traditionally been one of Ethereum's major bugbears despite many prior upgrades. Fusaka is thus the next step in the scaling process.
While Pectra was a success in terms of accomplishing what it set out to do on the scaling front, Fusaka will probably prove to be even more important in the long run.
It adds a hard cap on gas (user) fees per transaction, which should in theory rule out the perseverance of Ethereum's extremely frustrating habit of charging obscene gas fees in the range of dozens of dollars per transaction when the network gets congested. For the record, doing a simple token swap costs about $1.20 as of Oct. 30, with transactions settling in roughly 30 seconds -- which is much slower and more expensive than on other similarly sized blockchains, despite there being average to low traffic.

Key Data Points
The technical tidbits are worth appreciating here, at least from the 10,000-foot level. The core idea of Fusaka is to prevent single, bloated transactions from crowding blockspace, and to prepare the network for implementing safer forms of parallel execution later.
Ethereum already sets a base fee, but it does not limit the size of a single transaction. A per-transaction ceiling adds predictability, which is to say, it lowers the chance that one whale-sized transaction degrades everyone else's experience.
So if Fusaka improves blockchain strength and smooths transaction execution today, it sets the stage for significantly better throughput tomorrow while significantly improving the user experience in the meantime. If the chain ultimately builds out the ability to process transactions in parallel, it could potentially solve its scaling pains once and for all. And, it will be happening right on time, precisely when Wall Street and major asset managers are tokenizing their real-world assets (RWAs) and looking to networks like Ethereum to help with their capital management.
What could go wrong?
So Fusaka aims to make Ethereum into a more valuable platform by virtue of increasing its throughput and lowering its costs for users. That makes the setup fairly bullish, and, when taking into account all the other aspects of Ethereum's investment thesis, it's also a new reason to buy the coin, preferably before Fusaka launches in December.
But it's still worth stepping back and thinking about some of the risks here. Don't expect Fusaka to immediately juice prices, though it still might. Pectra delivered real functionality gains, but its immediate price impact was muted. Furthermore, it might not launch on time, and a delay would probably depress the price, at least a tiny amount, for a while.
Assuming a clean launch as planned, developer and user momentum will tilt a bit more in Ethereum's favor heading into 2026. There will still be fierce competition, and it is reasonable to assume that some of its competitors will still be significantly better at delivering fast and cheap transactions.
Nonetheless, progress is progress, and it's hard to believe that Ethereum will be less valuable in the future than it is today, given how much its underlying technology is being improved every couple of quarters.
