The Bitcoin Rainbow Chart predicts Bitcoin price for September. The chart indicates that Bitcoin ($BTC) could trade around $63,800 at the start of September 2026, based on the model’s current trajectory.
With Bitcoin changing hands at $63,258 at press time, the prediction implies a modest gain of less than 1% over the next two weeks.
The Rainbow Chart is a long-term valuation model that maps Bitcoin’s historical price action against a logarithmic growth curve to indicate whether $BTC appears overvalued or undervalued relative to past market cycles.
Following the chart’s current trajectory, Bitcoin is trading near the lower end of its historical valuation range, with the model implying a price of roughly $63,800 by early September. However, the Rainbow Chart is best viewed as a long-term valuation tool rather than a precise forecasting model.

The Rainbow Chart categorizes Bitcoin’s valuation using color-coded bands that reflect various market conditions.
The model's outlook for September 2027 shows that ‘Maximum Bubble Territory’ begins around $1.83 million and signals extreme market euphoria often associated with cycle tops. ‘Sell. Seriously, SELL!’ starts near $1.34 million and indicates substantial overvaluation.
