Bitcoin (CRYPTO:BTC) closed the second quarter of 2026 at $58,524 on June 30 and has since surged to $81,214 as of September 19, marking a remarkable 39% increase. To achieve its first green quarter in a year, the Bitcoin price must close above its June 30 position on September 30.

The last instance of Bitcoin finishing a quarter with a positive return was in Q3 of 2025. After peaking at an all-time high of $126,198 on October 6, 2025, Bitcoin has trended downward for three consecutive quarters, making this quarter’s close particularly critical for holders.

Despite its recent gains, Bitcoin remains in negative territory overall for the year, down 7.18% from its $87,498 close on December 31, 2025. The best outcome for September 30 is a green quarter that still falls within a red year. What factors must hold for this to happen, and what could derail it?
