What Are the Latest Large Bitcoin Short Positions by Major Traders?
Large Bitcoin short positions recently surged as a prominent trader expanded bearish bets, opening positions valued at approximately $119 million in Bitcoin on December 29, 2025. This activity included additional shorts of $106 million in Ethereum and $43 million in Solana, all placed through perpetual futures within five hours.

How Does Weak Spot Demand Impact These Bitcoin Short Positions?
The trader’s timing aligns with persistent softness in U.S. spot markets. Data from the Coinbase Bitcoin Premium Index stood at -0.086, reflecting Bitcoin’s discount on Coinbase compared to offshore exchanges. This negative premium historically points to limited buying from U.S. investors and institutions relying on regulated platforms.

Such conditions mean sell pressure from leveraged positions encounters minimal counterbalance from spot buyers. Experts note that sustained negative premiums often precede periods of range-bound or downward price drift, as derivatives markets gain dominance. According to market analysts, this dynamic favors bears until fresh spot inflows materialize.
