Ethereum entered September after one of its strongest monthly performances of 2026. The original altcoin gained about 32.6% in August, rising from roughly $1,860 at the start of the month to a high near $2,556 before closing around $2,466.
The rally continued into September, although price action became more volatile. ETH opened the month near $2,419 and briefly fell to about $2,358 on Sept. 3 before recovering through the middle of the month.
The strongest moves came later in September. ETH rose 6.7% on Sept. 18 to around $2,612, followed by another 4.9% gain on Sept. 21 that pushed the price above $2,775. The token briefly reached approximately $2,805 that day, its highest level of the month.
By Sept. 29, ETH was trading around $2,690. Despite the pullback from the monthly high, the token remained roughly 11% above its September opening level. The main question is, will there be an Uptober rally for Ethereum?
Ethereum rally: Institutional buying and profit-taking
The September price structure has been characterized by a sharp recovery followed by consolidation rather than a sustained one-way advance.
ETH has spent much of the past week between approximately $2,650 and $2,750, leaving the $2,700 to $2,800 area as an important zone for traders watching the next move.
Market sentiment has also improved from the September lows, although it remains mixed. One sentiment tracker put the average September reading at 59 out of 100, classified as "Neutral." Sentiment briefly reached "Greed" around Sept. 20 before weakening again.
Institutional demand has provided another source of support. Data from Arkham Intelligence shows that BlackRock's spot Ethereum ETF products have purchased more than $1.5 billion worth of ETH over a 20-day period.
The firm's ETHA fund accounted for approximately $1.27 billion of those purchases, while the newer ETHB product recorded around $296.5 million in ETH inflows during the same period.
BlackRock held approximately 3.56 million ETH, worth about $8.69 billion, as of Sept. 17, according to the data cited.
At the same time, some long-term holders have begun realizing gains following Ethereum's rally.
One early Ethereum investor recently reactivated a wallet that had been dormant for about nine years. The address originally acquired 3,000 ETH at an average price of $18.80 in 2017, for a total investment of approximately $56,500.
The wallet owner has since sold 2,000 ETH at an average price of about $3,096, generating approximately $6.19 million in proceeds. Another 1,000 ETH, worth roughly $2.67 million at the cited price, remains in the wallet.
Other large transactions have also pointed to profit-taking. During the final week of September, an investor whose Ethereum position dates back to 2023 transferred more than 112,000 ETH, valued at approximately $300 million, to Bitfinex. Separately, about 42,005 ETH, worth roughly $111.9 million, was reportedly sold through an over-the-counter transaction.
According to CryptoRank's quarterly data, Ethereum's Q3 2026 return stood at approximately 72.7%, which would make it the strongest third-quarter performance in the dataset. That follows declines of 29.1% in Q1 and 25.3% in Q2.
Ethereum price prediction: Can ETH break above $2,800?
Technically, Ethereum's structure has improved substantially since the June lows. ETH has moved above its previous $2,400 to $2,550 consolidation range, while shorter-term moving averages have risen below the current price.
The $2,350 to $2,400 area now represents an important short-term support zone, while a larger cluster of longer-term moving averages sits between approximately $2,180 and $2,250.
The next significant resistance area is around $2,700 to $2,800. ETH's ability to establish itself above this range could determine whether the September recovery develops into a broader fourth-quarter advance.
Momentum indicators remain elevated but have not reached the extreme levels seen during some previous rallies, suggesting that the latest move has not yet produced the same degree of overheating.
Technical analyst Ali Martinez, known as Ali Charts, has pointed to a previous breakout from a similar formation that was followed by a 31% gain over three days. In his analysis, a move above $2,474 could open a path toward $3,000. This remains a technical scenario rather than a guaranteed price target.
On-chain data has also provided a potentially supportive signal. Large holders previously withdrew more than $300 million worth of ETH from exchange addresses to cold wallets, reducing the amount of immediately available supply on exchanges.
For October, the main question is whether September's recovery can develop into a broader fourth-quarter rally. The "Uptober" narrative remains popular across crypto markets, but Ethereum's historical October performance has been mixed, meaning seasonality alone does not provide a reliable signal for the month ahead.
As of Sept. 29, Ethereum's market structure is considerably stronger than it was at the beginning of September.
However, ETH still faces resistance around $2,700 to $2,800, while profit-taking by large holders and the ability of institutional demand to continue absorbing supply could influence the next phase of the rally.
