Posting monthly gains in September has been no easy feat for bitcoin over the years. According to CoinGlass data, "Red September" could be a thing of the past:

Bitcoin closed September in the red in eight of the 13 years from 2013 through 2025, including six in a row from 2017 to 2022. Even after this year's gain, September's average return is negative 2.34%, the worst of any month, per data from CoinGlass.

But the tide has been turning. Bitcoin finished September up 3.91% in 2023, 7.29% in 2024 and 5.16% in 2025. This year would make it four in a row, the month's longest green streak in the data.
