Major Capital Positioning: BTC Options Show Bullish Bias as Implied Volatility Contracts, Negative Skew Signals Shifting Risk Appetite

Market activity reveals significant institutional positioning in BTC and ETH options ahead of Friday’s settlement, which will unlock approximately $2.1 billion in notional exposure. The most telling indicator is a substantial block trade execution: buyers accumulated BTC call options at the 100,000 strike (BTC-300126-100000-C), representing roughly 3,225 BTC with approximately $3.05 million in net premium paid—a clear signal that sophisticated capital is constructing upside structures.

Implied Volatility Compression Points to Calmer Pricing Environment

BTC implied volatility has contracted to 43%, while ETH IV stands at 60%, both reflective of moderating expectations for near-term price swings. This compression represents a notable shift from recent elevated volatility regimes, suggesting the market is repricing downside risk scenarios.

The Critical Negative Skew Narrative

BTC’s 25-Delta negative skew across multiple expiration dates has shown convergence over the past week, with negative values tightening across different maturities. ETH skew similarly maintains negative posture but demonstrates ongoing compression. This negative skew environment is particularly significant—it indicates that while downside protection remains priced in, the intensity of tail-risk concerns is gradually easing.

What It Means for Market Direction

Mainstream funds are clearly favoring bull call spread constructions above established support levels, allocating capital to capture potential upside moves while maintaining defined risk profiles. The combination of lower implied volatility, converging negative skew, and aggressive call buying suggests institutional players are rotating from defensive positioning toward constructive positioning in the current market cycle.
