The Bitcoin derivatives market is facing its most significant concentration event of 2025, with over $55 billion in options contracts set to expire on December 26. This unprecedented positioning, combined with unique gamma mechanics, could force a decisive showdown around the psychologically critical $100,000 level.
Market Context: The December 26 expiry represents not just another options expiration, but the largest single-date concentration of Bitcoin derivatives risk in 2025. With a put/call ratio of just 0.37 (indicating extreme bullish positioning), the stage is set for potentially explosive volatility.

"This concentration is unprecedented for 2025. The 0.37 put/call ratio shows overwhelming bullish bets, but the real story is in the gamma profile. Market makers could be forced into a feedback loop of buying if Bitcoin sustains above $119,000."

Understanding Gamma Mechanics and Price "Pinning"
Current analysis reveals Bitcoin's price is being influenced by the hedging activities of market makers—entities that provide liquidity in the options market. These players dynamically adjust their spot market positions based on changes in "gamma," creating what traders call "pinning" effects.
The gamma profile for December 26 is unusually flat compared to near-term expiries. This means as we approach the expiry date, the mechanical "pinning" effect weakens, potentially allowing for explosive volatility in either direction. The critical trigger level is $119,000—a sustained break above could initiate a gamma squeeze.
The December 26 Expiry: Asymmetric Positioning Analysis
Deribit data reveals extreme asymmetric positioning for the December 26 expiry. Calls dominate with a put/call ratio of just 0.37, indicating overwhelming bullish expectations. However, the distribution of these bets creates specific price levels that could act as volatility triggers.
Call Wall Concentrations: The options chain shows massive call open interest at $119,000 (first major resistance) and between $124,000-$130,000 (highest concentration zone). A break above these levels could trigger cascading hedging buys from market makers.

The Gamma Squeeze Scenario: Path to $130,000+
The current options configuration creates conditions for an accelerated upward move—a "gamma squeeze." Here's the potential sequence if bullish momentum builds:
Phase 1: Break $119,000 - Market makers who sold calls at this strike become exposed to upside risk and must buy Bitcoin to maintain delta neutrality. This hedging creates additional buying pressure beyond organic demand.
Phase 2: Momentum to $124,000-$130,000 - As price approaches the next major call concentration, the hedging feedback loop intensifies. Each upward move forces more hedging buys, creating a "snowball effect" that could accelerate the rally.
Phase 3: Speculative Targets in Play - If $130,000 is breached, attention shifts to the $150,000 and $170,000 calls. While these have less immediate hedging impact, they represent psychological targets that could attract additional momentum buying.
Conversely, a move below $108,000-$111,000 would encounter the wall of puts. However, the rapid time decay (theta) of these options as expiry approaches could absorb some selling pressure, unless triggered by significant external catalysts.
Supportive Macroeconomic Context
This technical options setup coincides with improving macroeconomic conditions. Markets are anticipating potential Federal Reserve policy easing in 2026, creating a favorable environment for risk assets like Bitcoin.
Supportive Fundamental Factors

The December 26, 2025 Bitcoin options expiry represents a convergence of unprecedented technical positioning and supportive macro fundamentals. With $55 billion concentrated on this single date and a put/call ratio of just 0.37, the setup favors bullish resolution—particularly if Bitcoin sustains above $119,000 and triggers gamma squeeze mechanics. While puts provide support between $105,000-$111,000, the asymmetric positioning suggests any breakout could be explosive, potentially setting Bitcoin's trajectory toward the $130,000-$150,000 range in early 2026.
