Bitcoin gained 43.88% in Q3 2026 after losses of 22.2% in Q1 and 14.09% in Q2, putting it on course for its strongest quarter since 2024. Over roughly the same period through Sept. 29, the Nasdaq Composite rose about 5%, the S&P 500 roughly 4% and gold less than 2%. US spot Bitcoin ETFs shifted from roughly $5 billion in year-to-date net outflows at the end of July to about $1 billion in inflows by late September, a $6 billion reversal.
Why it matters
The rally has continued despite an approximately 81-basis-point rise in the 10-year Treasury yield over the quarter. ETF buying has supplied capital while leveraged traders have pulled back: aggregate Bitcoin futures open interest fell from more than 700,000 BTC on Sept. 21 to about 644,000 BTC. Less leverage reduces the fuel for a liquidation-driven selloff, but also leaves less speculative buying to drive a sharp advance.
Seasonality adds to the bullish case, not a price guarantee. Bitcoin's historical average fourth-quarter gain is roughly 77% to 85%, depending on the dataset. BloFin Research calculates that repeating its 77.07% average from current levels would put Bitcoin near $147,000; its 47.73% median would imply about $123,000. Both figures are mechanical projections.
Market impact
Spot demand must first contend with supply closer to the market. Bitfinex estimates that investors acquired about 1.39 million BTC between $84,000 and $86,500, creating a potential selling zone. It estimates ETF demand of roughly $190 million a day, or five times daily miner issuance, would help absorb that supply more quickly.
A break through $86,500 would bring Bitcoin toward its yearly open near $87,700 and another supply concentration around $88,000 to $90,000. Bitfinex identifies $81,300 as a threshold below the recovery; sustained trading beneath it alongside renewed ETF outflows could expose the realized-price region near $77,000. The Oct. 2 US payrolls report and the Fed's Oct. 27-28 meeting will test the rate backdrop as Bitcoin enters its historically strongest quarter.

The funds moved from roughly $5 billion in year-to-date net outflows at the end of July to about $1 billion in inflows by late September, a swing of about $6 billion.
-
Why does falling Bitcoin futures open interest matter?
Aggregate open interest fell from more than 700,000 BTC on Sept. 21 to about 644,000 BTC. Less leverage can limit liquidation-driven selling, but it also reduces speculative buying that can accelerate gains.

No. BloFin Research calculated it by applying Bitcoin's historical average fourth-quarter return of 77.07% to current levels. It is a mechanical projection, not a guaranteed outcome.
