Historic Summer Rally Defies Seasonal Trends
Bitcoin has gained approximately 43.5% during the third quarter of 2026, climbing from around $58,500 at the start of the quarter to approximately $84,000. This performance puts the quarter on track to become bitcoin's second-best Q3 on record, behind only the roughly 80.4% surge recorded in 2017.
Ethereum has delivered even stronger results, rising 71% during Q3 according to Coinglass data. This marks ethereum's best third quarter performance ever, exceeding its previous Q3 record of approximately 66.5% set in 2025.
The combined performance breaks historical seasonal patterns. July, August, and September have traditionally been inconsistent months for crypto, often producing flat or modest returns compared with stronger fourth-quarter periods.
Market Fundamentals Support the Rally
The price gains have been accompanied by improving market conditions beneath the surface. Bitcoin has moved back above several investor cost-basis levels that had capped earlier recovery attempts. ETF demand has strengthened, spot trading volume has increased, and profit-taking remains relatively restrained.
Bitcoin successfully held through the large September 25 quarterly options expiry, an event that carried substantial open interest and had the potential to generate short-term volatility.
Q4 Outlook and Resistance Levels
The next major onchain resistance level sits near the mean MVRV price around $96,700. A move toward that zone would bring bitcoin within striking distance of the psychological $100,000 level.
Bitcoin is entering the final quarter with stronger ETF demand and improving spot activity, while ethereum is carrying record Q3 momentum. The immediate question is whether buyers can continue absorbing supply as bitcoin trades in the mid-$80,000 range.
