A $415 Million Bitcoin Gamma Flush is on the horizon, and the upcoming eight days are critical, according to market analyst David Eng. As we approach Christmas week, the focus in Bitcoin’s options market has intensified. In a recent analysis posted on Thursday, Eng highlighted that the period from December 19 to December 26 could significantly influence Bitcoin's near-term trajectory—not due to any major economic news or a sudden surge in exchange-traded funds (ETFs), but rather because a substantial amount of dealer gamma exposure is set to roll off during this time.
As of now, Bitcoin is priced at approximately $86,928, having fluctuated between about $84,461 and $89,230 throughout the day. Eng's perspective is straightforward, emphasizing the mechanics of options trading: the market is currently being artificially constrained, but this pressure has a deadline to meet.
What’s Really Holding Back Bitcoin Prices?
Eng pointed out that the situation extends beyond just the immediate future. "We are confronting what I term a 'Double-Barreled' Liquidity Event, which will eliminate 67% of the entire derivatives board by December 26," he stated. Currently, Bitcoin is trading near $88,752, which places it well within the -25% Value Zone (with a trend value estimated at $118,000). He suggests that while the potential for price movement exists, two significant structural weights are preventing it from rising.
These "weights" are tied to two key expiries with considerable gamma attached: roughly $128 million expiring on December 19 (accounting for 21% of the total he monitors) and an additional $287 million set to expire on December 26, which he describes as the "boss level" ceiling for the market. He refers to this combined total of $415 million as a forthcoming "Gamma Flush," claiming that once this pressure is lifted, the hedging constraints currently stifling spot price movements will begin to dissipate.
In simpler terms, if dealers are holding substantial gamma around a tight cluster of strike prices, their delta-hedging activities can reduce volatility and keep the price hovering around certain levels until that exposure either decays or expires. This situation creates a frustrating experience for traders who may wonder why prices seem stuck in place.
Eng has drawn specific lines in the sand, identifying $85,000 to $90,000 as the "mud zone," where hedging pressure keeps pushing prices back down, and $90,616 as the critical flip level to monitor as we approach the expiration on December 19. He elaborated:
"Stage 1: The Spark (Tomorrow, Dec 19)—$128 Million in Gamma expires tomorrow (21% of total). This acts as the 'Appetizer.' It removes the immediate suppression that has kept us below $90,000," he explained. "Keep an eye on the $90,616 flip level; if we surpass this point, the intraday restraints will be lifted."
However, Eng's main focus lies on the week following the first expiry. "Stage 2: The Floodgate (Next Friday, Dec 26)—$287 Million in Gamma expires next week," he continued. "A remarkable 46.2% of all dealer gamma exposure is concentrated on this one date. This gives dealers a powerful incentive—over a quarter of a billion dollars—to maintain low volatility and keep prices near $85,000 to $90,000 through Christmas in order to protect their premiums."
In essence, his outlook suggests that before December 26, the market is experiencing "thick mud," whereas after this date, the restrictions will lift, allowing prices to move more freely. "When you combine these two dates, a staggering $415 million of gamma—representing two-thirds of the entire market structure—will vanish in the next eight days," Eng noted. "Before December 26: The market is struggling through thick mud... After December 26: The mud dries up. The limiting factors will disappear, allowing the gravitational force of the Power Law ($118,000) to prevail without the opposing dealer flows."
Eng also mentioned a controversial ratio circulating within derivatives discussions this year: the strength of dealer mechanics compared to ETF demand. He observed, "Dealer Gamma forces are currently about 13 times more robust than ETF Flows," noting that dealer gamma stands at approximately $507.6 million compared to ETF flows of about $38 million. This disparity explains why the market is currently adhering to the technical gamma levels of $85,000 and $90,000 while largely disregarding ETF activity.
When some skeptics questioned the significance of the $287 million figure, Eng clarified its meaning, explaining, "The $287 million refers specifically to dealer gamma exposure (GEX), not the total size of options. GEX indicates how much Bitcoin dealers might need to buy or sell to remain delta-neutral amid price fluctuations. Therefore, it reflects hedging pressure rather than notional value."
Ultimately, Eng's thesis presents a clear trading implication: anticipate continued price stabilization heading into Christmas, and then observe whether the anticipated shifts in volatility materialize following the expirations. This will indicate whether Bitcoin can break free from its repetitive price patterns that feel as though they are hitting an invisible barrier.
At the time of writing, Bitcoin was trading at $87,953.
