Bitcoin’s 10% September Gain Puts Three-Month Streak Since 2012 in Reach

Bitcoin has gained 10% during September, placing it within reach of a three-month winning streak it has not recorded since 2012, according to a CoinDesk market brief dated Sept. 23, 2026.

A monthly gain with historical weight

A 10% monthly rise is the strongest concrete figure in the report. A calendar-month streak is determined by returns at successive month-ends rather than by any single daily price move. September therefore supplies the latest leg of the sequence, while the final monthly result still depended on how Bitcoin closed after the Sept. 23 report.

To complete the run, Bitcoin must finish September higher than it began, after registering positive returns in the two preceding calendar months. That combination would give the asset three consecutive positive monthly closes, matching the rare pattern last seen in 2012. The available brief does not provide the exact July or August gains, making 10% the only precise monthly return cited.

What the 2012 comparison establishes

The historical comparison gives the move more context than a one-month percentage alone. CoinDesk identifies 2012 as the most recent occurrence, but the brief does not compare current volatility, market structure, or returns with that earlier period. It would therefore be unsupported to attach a specific valuation thesis or forecast to the streak itself.

The report also leaves the cause of the advance unresolved. It provides no figures for trading volume, open interest, funding rates, spot exchange flows, or spot Bitcoin ETF flows. Those measures would help distinguish broad demand from a move driven by narrower positioning, but the available text does not support such a conclusion.

The final September close

September’s final close will determine whether the streak becomes a completed three-month sequence. If Bitcoin ends the month in positive territory, the run would match the most recent multi-month winning streak identified by CoinDesk. Until that close, “on track” is the precise description; declaring the milestone achieved would move ahead of the evidence.
