Bitcoin is closing in on an unwanted historical first: two consecutive calendar years of losses. After finishing 2025 down 6.34%, the largest cryptocurrency had lost another 15.65% in 2026 by November 10, trading around $73,850. To avoid a second straight red year, Bitcoin would need to recover above its 2026 opening price of roughly $87,500 before December 31, a gain of about 18.5% from current levels.
The combined decline across 2025 and 2026 is approximately 21% after compounding. That is far smaller than Bitcoin's 73.56% crash in 2018 or its 64.27% drop in 2022, but the peak-to-trough damage looks more severe. Bitcoin reached about $126,000 in October 2025 before falling below $58,000 during 2026, a drawdown of more than 50%. Analysts have pointed to a more institutional investor base, spot exchange-traded funds and deeper liquidity as reasons why bear-market drawdowns may be becoming less extreme.
The weakness has also undermined popular seasonal narratives. According to Kaiko research, October delivered Bitcoin's highest median return of 15.4% across 13 years through 2025, earning the month the label Uptober. Yet Bitcoin fell 7.3% in October 2026 after dropping about 4% in October 2025, producing the first consecutive October losses in the modern sample. Andrew Yang of Kaiko noted that Bitcoin's typical monthly price swing has shrunk from 14% between 2013 and 2016 to 9.6% since 2024, reducing the scope for sharp seasonal rallies. The October 2026 decline coincided with $643 million in single-session outflows from United States spot Bitcoin ETFs.
September's Rektember reputation is also cracking. Bitcoin averaged a September loss of about 3% through 2025, but it closed September green for four straight years from 2023 through 2026. Coinbase institutional research published in September 2025 tested calendar-month effects using multiple statistical methods and concluded that calendar month is not a reliable predictor of whether Bitcoin monthly returns will be positive or negative. Instead, path dependency may matter more: KuCoin Research found that in the 2016-2025 sample, years with negative first-half returns, 2018 and 2022, also finished lower. Bitcoin's first quarter in 2026 was down approximately 22.2%, reinforcing that bearish start.
