The crypto derivatives market is approaching one of its most important year-end events, as Deribit prepares for a record-setting options expiry worth roughly $28.5 billion on Dec. 26. The size of the expiry has turned the final trading days of the year into a key test for bitcoin price discovery, institutional positioning, and short-term market sentiment.
According to the report, the upcoming expiry represents more than 50% of Deribit’s total options open interest, making it the platform’s largest expiry on record. Deribit, now a subsidiary of Coinbase, is expected to see a major reset in positioning as traders close, roll, or re-establish exposure ahead of January’s macro and index-related catalysts.
Bitcoin dominates the expiry
Of the total notional value set to expire, around $24.3 billion is tied to bitcoin options, while about $4 billion is linked to ether contracts. The overall scale is nearly double last December’s year-end expiry, underlining how much larger the market for crypto options has become over the past year.
Deribit Chief Commercial Officer Jean-David Pequignot said the size of the event reflects a maturing market increasingly shaped by institutional participation rather than speculative retail excess. That distinction matters because large expiries can influence hedging behavior, dealer positioning, and near-term price dynamics even when spot volumes appear thin, especially during holiday trading conditions.
Large expiry, but volatility remains relatively contained
Despite the headline size of the event, volatility has not surged into the expiry. The report notes that bitcoin’s DVOL Index is hovering near 45, suggesting that implied volatility remains relatively restrained even as holiday liquidity becomes thinner. In other words, the market is facing a very large derivatives event, but not in an environment of outright panic.
That contrast is important. A giant expiry does not automatically mean dramatic price swings, but it does raise the odds that positioning changes after settlement could influence the next directional move. With a significant portion of open interest rolling off at once, traders are watching whether the event leads to a sharp repricing or simply clears the decks for January.
Why the $96,000 “max pain” level matters
As of 3:30 p.m. EST on Dec. 22, bitcoin was trading at approximately $87,981, below the $96,000 max pain level associated with the expiry. In options markets, max pain refers to the price where the greatest number of contracts expire worthless, making it a closely watched reference point into settlement windows.
The report also highlights a put-to-call ratio of 0.37, indicating that overall positioning remains more call-heavy than put-heavy. That is generally interpreted as a sign that medium-term sentiment still leans bullish. However, the market is not positioned for a one-way move. A substantial open-interest cluster of roughly $1.2 billion at the $85,000 strike could act as a short-term magnet for price action, particularly if liquidity remains limited.
Call-heavy medium-term bets meet near-term caution
Pequignot said options skew has softened after strength seen in late November and early December. One-week and one-month put-call skews remain in positive territory above 3%, but that is down from roughly 8% to 9% seen just a few weeks earlier. The shift suggests traders have repriced downside protection somewhat lower, even if defensive demand has not disappeared.
This creates an important divergence in the market. On one hand, medium-term positioning remains notably bullish, with traders using calls and call spreads to target the $100,000 to $125,000 range. On the other hand, protective puts are still relatively expensive in the near term, showing that traders are not fully comfortable heading into year-end without downside hedges.
That combination points to a market that still sees upside potential in the months ahead, while also acknowledging that the path there may be uneven. It is a classic late-year setup: directional optimism beyond the immediate horizon, paired with tactical caution into a major expiry and a seasonally thinner market.
Resistance may build near $100,000 to $102,000
The report says call-side positioning is concentrated near the $100,000 to $102,000 area. That concentration could create a zone of heavy resistance if bitcoin attempts a late-year rally. Unless trading volume accelerates meaningfully, those option strikes may cap upside in the near term as dealers and market participants manage exposure around settlement.
Such strike clusters often matter because they shape how hedging flows develop as spot approaches key levels. While the report does not claim a guaranteed price outcome, it does suggest that the structure of the options market could make upward progress more difficult unless there is enough momentum to break through those concentrations.
Traders are already looking past December
Another notable takeaway is that traders have been rolling defensive positions forward. Instead of keeping all downside hedges in December maturities, some market participants are moving protective puts into January structures. That behavior indicates the market is not focused solely on the Dec. 26 event itself, but also on what comes immediately afterward.
Pequignot pointed to several January catalysts, including the Federal Reserve’s late-January policy decision and an MSCI-related ruling tied to digital asset treasury exposure. These are the types of events that can reshape macro expectations, asset allocation flows, and risk appetite across crypto and traditional markets alike.
According to CME’s FedWatch tool cited in the report, there are 36 days until the next Fed meeting, and the probability that the central bank will leave the federal funds rate unchanged stands at 80%. While that implies relative stability in rate expectations for now, traders still appear eager to preserve optionality into the new year.
A defining moment for crypto price discovery
Whether the Boxing Day expiry produces fireworks or a quieter reset, the event underscores a broader trend: crypto derivatives are now central to market price discovery. The sheer scale of this expiry suggests that institutional positioning, hedging flows, and strike-based exposure have become increasingly influential in shaping short-term price action.
That matters for bitcoin in particular. With most of the notional value tied to BTC options, the market is effectively using this expiry as a major year-end clearing event. Spot price, dealer hedging, option skew, and post-expiry reallocation could all play roles in determining whether bitcoin enters 2026 with renewed momentum or pauses before the next macro catalyst.
In that sense, the significance of the expiry extends beyond a single trading session. It offers a snapshot of how the crypto market has evolved: less driven by retail hype, more influenced by institutional derivatives activity, and increasingly sensitive to the intersection of macro policy, index decisions, and structured positioning.
For traders, the message is straightforward. The Dec. 26 expiry is not just another calendar event. It is one of the largest option resets the crypto market has seen, and its aftermath may help define the tone for bitcoin and the broader digital-asset complex as January begins.
