Bitcoin price ended the third quarter with a roughly 43% gain after briefly reclaiming $85,000 following the latest U.S. inflation report.
The advance marked Bitcoin’s strongest third quarter since 2017 and its best quarter overall since late 2024.
Late-September ETF inflows and another Bitcoin purchase by Strategy added to demand indicators. Meanwhile, softer-than-expected PCE inflation reduced market pricing for another Federal Reserve rate hike in October.
Bitcoin Price Posts Strongest Q3 Since 2017
Bitcoin has been showing significant strength relative to other traditional assets, outperforming US equities and Gold. In September itself, the BTC rally continued with 7% gains, while the S&P 500 remained flat and gold prices declined by more than 6%, reported analysts at Santiment.

With the easing of US PCE inflation in August, Bitcoin quickly moved above $85,000 on September 30. On the other hand, the institutional demand for Bitcoin remains robust.
U.S. spot Bitcoin ETFs attracted billions of dollars in September, including several large inflow days late in the month. On the other hand, Michael Saylor’s Strategy resumed strong buying, adding 1,665 Bitcoins earlier this week.
Looking ahead to Q4, Santiment pointed out a few factors that could support a Bitcoin rally. It noted that continued ETF demand, corporate accumulation, improving regulatory clarity, and renewed altcoin participation to support overall market momentum.
