Bitcoin (BTC) is ending the third quarter of 2026 with its strongest summer performance in nine years.
The world's largest cryptocurrency has gained 43% since the start of July.
That makes it Bitcoin's best third quarter since 2017, when prices jumped 80.4%, and its best quarter of any kind since late 2024.
The rally stands out because it came right after two straight quarterly losses, during what is usually one of Bitcoin's weakest stretches of the year.

A break from bitcoin's usual summer slump
Historically, Q3 hasn't been kind to Bitcoin. CoinGlass data shows the quarter ended in the red in 2014 (-39.74%), 2015 (-10.05%), 2016 (-9.41%), 2019 (-22.86%), 2022 (-2.57%) and 2023 (-11.54%).
Recent years were flat at best: Bitcoin gained less than 1% in Q3 2024 and 6.3% in Q3 2025.

Institutional demand did much of the work this quarter.
U.S. spot bitcoin ETFs pulled in about $2.4 billion in the week ending Sept. 25 alone, and Michael Saylor's Strategy returned to buying after a 10-week pause, adding about 7,200 BTC since late August and bringing its holdings to 847,666 BTC.
Regulatory news helped too. Though the CLARITY Act stalled in the Senate, new SEC and CFTC rules lifted sentiments.
The SEC introduced its five-year “Innovation Exemption,” on Sept 17. It created a pathway for qualifying platforms to trade tokenized U.S. stocks onchain. The framework allows tokenized securities to retain the same shareholder rights as their underlying stocks while giving issuers the ability to object.
The CFTC submitted “Regulation Crypto Asset Transactions and Regulation Crypto Asset Markets” to the White House Office of Information and Regulatory Affairs for review.
However, Bitcoin wasn't the quarter's top performer.
Ether gained nearly 71%, Solana rose about 59% and Chainlink roughly doubled. But, most major cryptocurrencies are still down for the year.

Rally loses steam
The rally lost steam late in the quarter. Bitcoin hit an eight-month high near $87,400 in September, then slipped as the 10-year Treasury yield climbed above 5.2% and the Federal Reserve raised interest rates on Sept. 16 for the first time since 2023.
Wednesday's softer-than-expected PCE inflation report gave some relief. Traders cut back bets on another Fed rate hike in October after the data came out.
The Fed's upcoming Oct. 27-28 meeting will likely set the tone. Slowing ETF inflows also suggest bitcoin may need fresh demand to extend its rally.
