Three data points show synchronized fluctuations, with Bitcoin short pressure mounting; BTC may experience a sharp rebound.

Bitcoin continued to experience high volatility in early January, with the price once approaching the $90,000 level. Behind this oscillation, the derivatives market is signaling a noteworthy development: short positions are building up pressure. Analysts point out that negative funding rates, rising open interest, and high leverage are creating a market structure unfavorable to shorts. Once a rebound is triggered, it could lead to a classic short squeeze.

Three Key Anomalies in the Derivatives Market

Funding rates turn negative, short dominance but fragile structure

According to analyst Burak Kesmeci, the funding rate for BTC perpetual contracts on mainstream CEXs has turned negative on a daily chart (currently around -0.002), the first time since late November 2025. Negative funding rates indicate short dominance, but there’s an important detail behind this signal: the funding rate remains negative while the price has not experienced a deep breakdown, often implying that short positions are starting to weaken.

Historical data offers reference. After the last time the funding rate turned negative, Bitcoin rebounded from $86,000 to the $93,000 range. This suggests that when the funding rate reaches extreme negative levels, the market has usually accumulated enough momentum for a rebound.

Open interest increases, shorts are accumulating positions

The second signal is more straightforward. Recently, as BTC price retreated, open interest (OI) in the futures market continued to rise. What does this “price decline coupled with increasing OI” imply? It indicates that new short positions are being concentrated, rather than longs exiting.

This structure has particular technical implications. Once the price rebounds, the crowded short positions can easily trigger forced liquidations, amplifying the upward move. This is a typical mechanism of a short squeeze.

Leverage ratio rises to near-month highs, risk triggers imminent

According to CryptoQuant data, Bitcoin’s estimated leverage ratio has risen to near a one-month high. In a high-leverage environment, even a small rebound could trigger chain liquidations. Once liquidations begin, shorts are forced to buy BTC to cover, further pushing up the price. This structural risk is especially evident in the derivatives market.

Market Structure Assessment: Risk Tilted Toward Shorts

The combination of these three indicators suggests that the market has accumulated sufficient conditions for a potential short squeeze. Negative funding rates reflect short dominance, but the crowded short structure and high leverage environment make this strength vulnerable.

Conditions for Rebound and Expectations

Currently, BTC is around $90,826.60, a critical level for understanding subsequent movements. Rebound is not guaranteed but requires clear driving factors. Possible triggers include:

• Resurgence in spot demand (institutional or bulk buying)
• Macro-level positive catalysts (policy, economic data, etc.)
• Technical breakthroughs (price breaking through key resistance levels)

Once these conditions materialize, chain liquidations in a high-leverage environment could rapidly amplify the upward move. Historical data shows that similar signals often lead to rebounds of 5-10% or more.

Summary

The three anomalies in the derivatives market are constructing a structure unfavorable to shorts. Negative funding rates, rising open interest, and high leverage together suggest that the market has accumulated enough rebound energy. While a rebound is not certain and depends on clear triggers, the current risk balance in the BTC market is gradually tilting toward the upside. For traders, key considerations include whether clear driving factors emerge and how the support near $90,000 holds. If support remains firm and positive catalysts appear, the risk of a swift rebound warrants close attention.
