#ETH $ETH ‌ETH Rises 30% in a Week: Early Signal of a Major Rally or Mere Euphoria?

Ethereum has just delivered a rarely seen signal. Within a week, ETH surged around 29–30%, marking its largest weekly gain since May 2025. The move even saw ETH outperform Bitcoin, which rose around 21% over the same period.
For Tom Lee, that figure is more than just a statistic. He believes historical patterns show that when ETH manages to post a gain of around 30% in one week, a major move may only be getting started.
The two previous examples are particularly interesting: after a similar weekly surge in July 2021, ETH subsequently rose around 167%. In May 2025, the pattern emerged again and ETH continued rising around 170%.
What is different this time: capital is beginning to follow the price
ETH's current rise is not happening in isolation.
U.S. spot Ethereum ETFs recorded strong inflows, while BitMine—the company led by Tom Lee—just purchased 32,447 ETH worth around $81 million, its largest weekly purchase since early July. BitMine's total holdings have now reached around 5.85 million ETH, equivalent to around 4.8% of Ethereum's circulating supply.
This gives the latest rally a different character:
Price rises → ETFs absorb ETH → corporate treasuries continue accumulating → liquid supply could become increasingly tight.
On the other hand, ETH is also beginning to gain new momentum as infrastructure for asset tokenization, stablecoins, and blockchain-based AI applications. Lee previously estimated that capital rotation from Bitcoin into Ethereum began after ETH lagged for years.
But history is no guarantee
There is one trap that must be avoided.
A 30% rise in a short period also makes ETH vulnerable to profit-taking and a technical correction. Some market data even indicates that momentum conditions have become overheated after ETH reached the area around $2,500.
Therefore, Tom Lee's signal should be interpreted as a probability indicator, not an automatic target.
More important to monitor is whether ETH can sustain its breakout after the euphoria subsides.
Conclusion
30% is not the finish line. It could instead be an alarm that the market is entering a new phase.
If the 2021 and 2025 patterns recur, ETH's upside could still be far greater than the rally of the past week. But this time, there are additional factors that differ from previous cycles: ETFs, corporate accumulation, staking, and Ethereum's growing use as financial infrastructure.
The biggest question now is not “has ETH already risen too high?” but whether the price increase is opening the door to a much larger phase of institutional accumulation.
If the answer is yes, then a 30% rise may not be the peak, but an early signal.
