Bitcoin rose 42.8% and Ethereum 71.1% in Q3 2026. It was BTC's best third quarter since 2017 and the best third quarter in ETH's history.
So nothing has changed: BTC and ETH once again closed the September monthly candle in the green, wrapping up a very strong third quarter for the market.
Bitcoin: best Q3 since 2017
- BTC rose 42.8% in Q3 2026, its highest Q3 gain since the 2017 cycle (Q3 2017: +80.4%).
- The price broke out of a mid-term accumulation range that had lasted for several months.
- Strong support sits around 82,000 USD, with resistance around 86,000 USD.
- Note: because of the sharp declines in Q1 (−22.2%) and Q2 (−14.1%), BTC is still about 5% below its 2026 yearly open.
Ethereum: best Q3 in its history
- ETH rose 71.1% in Q3 2026, beating the previous Q3 record of +66.6% set in 2025.
- The ETH/BTC pair formed a clear reversal bottom, suggesting capital is flowing back into ETH.
Macro backdrop
- After the Sep 30 PCE inflation data, the probability of the Fed holding rates at its October meeting rose to 52.9%, according to CME FedWatch.
- The US–Iran conflict and oil prices remain risk factors to watch in Q4.
