Bitcoin short sellers have intensified their positions as the year-end approaches, with selling pressure surpassing levels seen during Trump's 2025 tariff wars. The Taker Buy Sell Ratio has significantly declined, indicating a bearish trend. U.S. Spot ETFs have experienced daily outflows since December 18, and CME Open Interest has fallen below $10 billion for the first time since September 2024. Institutional demand has weakened, with basis trade yields dropping from 10% to 5%. Market analysts predict a potential decline below $80,000 in early 2026, posing risks for leveraged short positions if Bitcoin prices rise. Options trading volumes are concentrated at $85,000, $88,000, and $90,000, as major players hedge against a possible drop to $85,000.
