In September 2025, Bitcoin’s price exhibited notable volatility while maintaining an overall upward trajectory. Starting from a close of $109,250.59 on September 1 (following a close of $108,236.71 on August 31, 2025, which marked a modest initial gain of about 0.9% into the month), BTC quickly climbed to a monthly peak of $117,137.20 on September 18 amid strong bullish momentum and elevated trading volumes (peaking at over 75 billion USD on September 25). This surge represented a roughly 8.2% increase from the August 31 close.
Mid-month, prices stabilized in the $115,000 – $117,000 range, reflecting sustained investor interest possibly driven by broader market dynamics.
