Bitcoin price ended the third quarter of 2026 with a gain of roughly 43%, briefly reclaiming the $85,000 level 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 inflows into spot Bitcoin ETFs and another large purchase by Strategy added to a growing list of demand indicators, while softer-than-expected PCE inflation reduced market pricing for another Federal Reserve rate hike in October.

Strongest Third Quarter Since 2017

Bitcoin has been showing significant strength relative to other traditional assets, outperforming U.S. equities and gold. In September alone, the BTC rally continued with a 7% gain, while the S&P 500 remained flat and gold prices declined by more than 6%, according to analysts at Santiment. The analytics firm noted the divergence between Bitcoin and traditional assets during the month.

With U.S. PCE inflation — the Federal Reserve's preferred inflation gauge — easing in August, Bitcoin quickly moved above $85,000 on September 30. Institutional demand for the asset has remained robust. U.S. spot Bitcoin ETFs attracted billions of dollars in September, including several large inflow days late in the month, while Michael Saylor's Strategy, the software company formerly known as MicroStrategy, resumed strong buying, adding 1,665 BTC earlier this week. Spot ETFs hold bitcoin directly and trade on U.S. exchanges, which makes their daily flow data a widely followed gauge of institutional participation. Taken together, the ETF inflows and Strategy's latest purchase point to a return of institutional demand for Bitcoin.

Looking ahead to the fourth quarter, Santiment pointed to several factors that could support a Bitcoin rally, noting that continued ETF demand, corporate accumulation, improving regulatory clarity, and renewed altcoin participation could underpin overall market momentum.

Macro Conditions Align in Bitcoin's Favor

In Q3 2026, Bitcoin price registered a gain of approximately 40%, putting it on track for its strongest third quarter since 2017. The rally follows two consecutive negative quarters and marks one of the fastest recoveries for the asset in recent years.

Macro indicators are aligning favorably as well. As inflation showed signs of cooling off, the odds of a Federal Reserve rate hike in October fell to 38.2%, down from 50.4% a day earlier. Markets now assign a 61.8% probability to the Fed holding rates steady at its October meeting, according to data from AskClash. The declining odds of a hike point toward better liquidity conditions heading into the final quarter. Rate expectations carry extra weight in crypto markets because dollar liquidity conditions shape the backdrop against which risk assets trade.

Seasonal patterns may also lend support. Historical monthly return data show that October has traditionally been one of the stronger months for Bitcoin, with BTC closing higher in 10 of the 13 years since 2013 — a record of positive monthly returns that has earned the month the nickname "Uptober."

Long Positions Build Up

Crypto analyst CW said net buying of Bitcoin (BTC) long positions is continuing, pointing out that Bitcoin open interest (OI) and net position delta are steadily increasing. According to CW, the trend follows the conclusion of short covering, with fresh buying now driving growth in long positions.

The odds of Bitcoin reaching $100,000 are currently around 35%. It remains to be seen which catalysts can support a further BTC rally in the weeks ahead. Near-term markers include the Federal Reserve's October rate decision, the pace of spot ETF flows, and whether corporate buyers such as Strategy keep adding to their holdings — the same factors Santiment flagged as potential supports for fourth-quarter momentum.
