Ethereum: Why ETH faces October reversal risk after 70% Q3 rally

Ethereum [ETH] has started October facing a FUD vs. FOMO battle.

According to AMBCrypto, this ongoing battle could determine ETH’s October outlook. Interestingly, ETH’s Q3 rally pushed the asset into the spotlight, with a 70%+ ROI, marking the best Q3 performance in history. That means Ethereum is going into October on a bullish note, with FOMO likely to sustain the HODLing and buying.

However, the latest Santiment data shows a diverging trend. In particular, Ethereum’s sentiment meter reading has declined to 0.89 bullish comments per one bearish across the X, Telegram, Reddit, and other social media platforms. The key takeaway? It is the ETH’s lowest ratio since the 7th of June.

For context, the ratio below 1.0 makes the bearish talk prevailing as compared to the bull runs. As a result, there may be a bearish turnaround for Ethereum after a stellar third quarter.

However, analysts point out that this could be a contrarian setup.

Pessimism could create a contrarian setup for ETH. In a situation where traders become fixated on the idea of prices going down, most of the panic selling has probably already occurred. Santiment’s social analysis indicates that rising fear and lower optimism can create a better entry setup than the classic “buy the dip” narrative.

The key question at this point is whether on-chain data supports this bullish outlook. Given Ethereum’s classic FUD-vs.-FOMO environment, the bigger question is whether on-chain data is flashing warning signs of weakness, or if the bears are simply getting ahead of themselves.

Is Ethereum’s Q3 setup now facing a reality check?

Ethereum’s Q3 surge may be skewing the FOMO vs. FUD battle towards the bears.

Notably, recent on-chain developments suggest just that. ETH traders are shifting towards a more bearish stance. This is evident in Binance’s weekly Taker Buy/Sell Ratio, which dropped to 0.95, the lowest level in over four months, indicating that taker sells outnumbered taker buys.

Meanwhile, co-founder Joseph Lubin has shifted a further 133,298 ETH (worth over $356 million) to a new wallet, adding further uncertainty over the outlook for the altcoin in October.

But the bearish scenario has not ended yet. According to the chart below, the exit queue for Ethereum has climbed to 773,447 ETH, hitting the highest level since the beginning of 2026. This means that over 773k ETH are waiting to exit staking and enter the market if the conditions allow. Moreover, Ethereum ETFs have recorded a 1-day net outflow of 5,171 ETH, or $13.89 million.

Combined, the signals suggest that FUD around Ethereum is not only originating from social sentiment but is also now starting to emerge in the on-chain positioning.

This is clearly different from the contrarian set up that analysts had identified. Given that ETH has already appreciated by more than 70% in Q3, the rise may well be due for a reality check in Q4. If the bearish on-chain trend persists, October is likely to become the turning point for Ethereum’s strong Q3 performance and the broader reversal.

Final Summary

• Ethereum faces rising selling pressure as bearish signals build.
• Could the 70% Q3 rally reverse and trigger an October pullback?
