Ethereum gained roughly 60.62% in the third quarter of 2026 after breaking above $2,600 from a multi-month range between $1,800 and $2,000. The performance followed declines of 29.26% in Q1 and 25.28% in Q2 and far exceeded the historical average Q3 return of approximately 12.28%. The source initially described the gain as Ethereum’s best Q3 performance, but later ranked it second-best on record behind the 66.55% return in Q3 2025 and ahead of the 59.5% gain in Q3 2020. Institutional demand included more than $10 billion in cumulative spot Ethereum ETF inflows, nearly $4 billion in August alone, and over $15 billion in corporate ETH purchases. Ethereum’s total value locked across its network and Layer-2 networks reached approximately $88 billion. ETH later traded above $4,000 and approached $5,000 before a late-September pullback, while analysts said the earlier breakout needed sustained support above $2,550 to confirm a durable higher range.
