- Bitcoin is set to close September with a rare positive gain of 4.5 percent.
- Historically, a green September has preceded an average fourth-quarter surge of more than 50 percent.
- If the pattern holds, Bitcoin could be eyeing the $170,000 region by year-end.
In a powerful and unusual challenge to its own grim history, Bitcoin is poised to finish September in positive territory.
This is significant. September has long been the harshest month on the crypto calendar, a steady sea of red that earned it the ominous label “Red September.”
But this year, a 4.5 percent uptick has shifted the narrative and may have ignited the fuse for an explosive rally in the final quarter of the year.
A pattern written in the charts
History may not repeat exactly, but it often rhymes—and in Bitcoin’s world, the rhyme of a green September is a powerful, bullish signal.
Historical data show that in the rare years when Bitcoin closed September in positive territory—2015, 2016, 2023 and 2024—the fourth quarter delivered spectacular returns, averaging more than 53 percent.
In those years, Q4 gains ranged from a strong 45 percent to an impressive 66 percent.
If that historical pattern repeats this year, Bitcoin could be targeting the roughly $170,000 range before the calendar flips to 2026.
Data indicate that October often serves as the launchpad for these powerful moves, posting an average gain of 21.8 percent, with November typically continuing the ascent.
This seasonal effect has been particularly potent in post-halving years, when a combination of fresh capital inflows and bullish market positioning tends to push the asset into a new phase of price discovery.
On-chain outlook: a bullish tide is shifting
This bullish seasonal setup is not merely a statistical quirk; it’s being corroborated by deep, underlying flows visible on the blockchain itself.
Key on-chain metrics are now flashing green, signaling a meaningful shift in market momentum.
The Spot Taker Cumulative Volume Delta (CVD)—an important indicator that measures the net difference between buy and sell volumes in the market—has turned positive over the past 90 days for the first time since mid-July.
That is a clear and direct sign that a “taker buy-dominant phase” is underway, a period in which buying pressure decisively outpaces selling activity.
At the same time, Coinbase’s premium metric has highlighted steady and aggressive accumulation by U.S. investors during the third quarter.
The robust alignment of these two key on-chain signals supports the view that a new wave of buying momentum is not just approaching—it is already present.
The stage is set, signals are aligning, and the last quarter of the year could once again prove decisive and explosive for the world’s leading digital asset.
