- Bitcoin price gained roughly 7% in September, outperforming a largely flat S&P 500 as December gold futures fell 6.6%
- Strategy bought another 1,665 BTC, while renewed Bitcoin ETF inflows supported the recovery heading into Q4
- Peter Brandt sees a possible price prediction of $300K–$600K for Bitcoin by late 2029, but warns of an October pullback toward $65K–$66K
Bitcoin price gained roughly 7% in September, giving traders a stronger finish to a month that has often disappointed them. Gold lost ground, while stocks struggled to keep pace with crypto’s latest recovery. The move has renewed interest in Bitcoin Q4 prospects, but Peter Brandt’s latest forecast comes with a near-term warning. Before the market gets anywhere close to his six-figure targets, he thinks late buyers could face another uncomfortable drop.

Bitcoin’s September Price Gain Comes With Fresh Buying

Santiment’s market comparison put Bitcoin’s September gain at roughly 7%, against a largely flat S&P 500 and a decline of more than 6% in gold. Separate Dow Jones data showed December gold futures finished the month down 6.6% at $4,186.70 an ounce. The gold price decline offered a sharp contrast to Bitcoin’s recovery.
Bitcoin was also heading into the quarter-end with a gain exceeding 40% since July, putting it on course for its strongest quarter since Q4 2024. Corporate buying continued alongside the rally. Strategy announced another 1,665 BTC purchase on September 28.
Bitcoin ETFs have attracted renewed inflows, adding another source of demand. Their ability to keep drawing money after the recovery will matter more than a single strong session. September’s gains give October a firmer starting point, though they leave buyers entering now at substantially higher prices than those available in June.

Brandt’s $600K Forecast Includes a Pullback Warning
In a recent interview, Peter Brandt said Bitcoin’s late-June decline toward $58,000 may have marked the cycle bottom. His Bitcoin price prediction places the next peak between $300,000 and $600,000 in late 2029. He added,
“There’s a good possibility we have seen the low and now are entering a new bull market cycle in Bitcoin. If Bitcoin’s $350,000 in late 2029, I’m not gonna be a million-dollar bull.“
He also outlined a possible retreat toward $65,000 or $66,000 in early October. His concern is that traders who rushed into the recovery have become too heavily positioned, leaving them vulnerable to a reversal.

Brandt’s outlook assumes a new bull market has begun and that historical cycle patterns remain useful. His higher target is therefore conditional. It sits along with a willingness to buy gradually rather than commit his entire planned allocation immediately.
For October, the question is whether fresh demand can absorb selling after September gains. Continued ETF inflows would strengthen that case. A sharp reversal would give Brandt’s pullback warning more immediate relevance than his 2029 target.
