3 Reasons Why September Could Be Bullish for Ethereum (ETH)

If ETH closes this month in positive territory, it would be the first time ever it posts back-to-back gains in August and September.

August has been the best month for the second-largest cryptocurrency so far this year, and now bulls have set their attention on September, expecting additional gains in the next four weeks.

Check out what suggests that a further green wave could indeed be in the cards.

The Positive Factors

As of this writing, ETH trades at around $2,380 (per CoinGecko), representing a 28% monthly pump. Its strong performance comes on the back of a broader market resurgence witnessed during the second half of August. Recall that BTC briefly jumped past $81,000; one can explore the exact catalysts in our detailed article here.

For its part, ETH temporarily climbed above $2,550, while growing institutional demand suggests the local peak may be surpassed this month. SoSoValue’s data shows that spot ETH ETFs have closed 12 consecutive green days, attracting over $1.5 billion in capital within that period. The last time the funds recorded such a sustained run was in July 2025.

Next on the list is the amount of ETH stored on cryptocurrency exchanges. Just a few days ago, the figure dropped to around 14.9 million coins, the lowest since the summer of 2016. Currently, it stands at around 14.99 million, which is quite close to the depicted bottom. Such a development signals that investors have abandoned centralized platforms in favor of self-custody, thereby reducing immediate selling pressure.
