My analysis focuses on the structural mechanics of the Deribit options market and the specific statistical properties of the “maximum absolute deviation” metric. As of July 7, 2026, Bitcoin is trading near $63,000, significantly below its 2025 peak of approximately $126,000. This price history is critical because Deribit maintains a strike grid that includes “legacy” high-strike options—calls with strikes at $150,000, $200,000, and even $300,000—that were listed when the market was significantly higher or more bullish.
When a trader’s account reaches the maintenance margin threshold, the Deribit risk engine does not just liquidate at-the-money positions; it executes incremental or total portfolio takeovers. This process forces the liquidation of all positions in an account, including deep out-of-the-money (OTM) “wings.” Because the formula for deviation is ((Strike - Index) / Index) 100, the mathematical ceiling for negative deviations is -100% (since a strike cannot be below zero). However, the ceiling for positive deviations is effectively unbounded by the exchange’s listing policy. A liquidation of a $200,000 call against a $60,000 index produces a +233% deviation. Given that the question resolves to the event with the maximum absolute* value, these large positive deviations will almost always “outcompete” negative ones.
I have weighted the forecast toward positive values (roughly 85-90% probability) because for a negative value to win, there would have to be zero liquidations of any option with a strike higher than roughly 1.8x the spot price over the entire 28-day window. This is statistically unlikely given the $9 billion in open interest and the recent history of $1 billion+ daily liquidation cascades in June 2026.
The primary component of my forecast (the 50% HDI) is centered between 19.3% and 139.7%. This range reflects the most active OTM call clusters ($75,000 to $150,000) being liquidated while Bitcoin trades in its projected $47,000 to $78,000 range. The upper tail of the 80% HDI (extending to 224.5%) accounts for the liquidation of longer-dated, extremely high strikes ($200k+) or a significant drop in the index price during a liquidation event, which mechanically inflates the Strike/Index ratio. I assigned a small weight (~8-10%) to a resolution of 0, representing the possibility that no qualifying option liquidations are recorded in the REST API, though the ongoing SignalPlus trading competition makes this outcome less likely.
Question: whether any Deribit BTC option trade in the July 15–Aug 11 window will be flagged as a liquidation, and if so which flagged option trade has the largest signed strike/index gap. Forecasters agree this is a sparse trade‑tape event with a large atom at exactly 0: a historical scan of 24 non‑overlapping 28‑day windows found 13/24 (≈54%) had no qualifying BTC option liquidations, so about half the probability mass should sit at 0, though teams downweight that a bit because current options OI is large and markets have been somewhat stressed. If at least one liquidation appears, all teams expect an asymmetric distribution biased positive: July 31 shows heavy high‑strike call OI (70k–120k strikes) that can produce +25% to +90% signed deviations at current ~63k spot, while common put clusters are concentrated nearer -20% to -35% and thus produce smaller absolute negative gaps. Typical nonzero outcomes are therefore in roughly -30% to +70%, with historical nonzero maxima from about -20% to +110% and small open tails for very far wing events (tiny mass beyond -80% or above +500%). Key operational caveats agreed by forecasters: resolution depends on Deribit’s optional one‑hour delayed liquidation flag (don’t treat an early empty REST pull as definitive) and public retention limits mean frequent snapshots or an enterprise historical feed are needed for robust adjudication. For live monitoring, focus on flagged option trades in the REST recent‑trades/historical tape, deduplicate by trade_id, apply the one‑hour delay, and watch July 31 expiry strike clusters and realized/IV‑driven stress that could push short option accounts into liquidation.
Forecast: Probability distribution:
We are forecasting an extreme-value statistic: among all Deribit BTC option trades flagged as liquidations (“M”,”T”,”MT”) between 2026-07-15 and 2026-08-11, take the single event with the maximum absolute value of ((Strike−Index)/Index)*100, and report its signed value (tie in absolute value resolves positive).
Key drivers:
Synthesis: I place most mass on a positive outcome in roughly the ~50% to ~250% range (maximum over the window, not a typical liquidation), with a meaningful but not dominant chance of 300%+ if a liquidation occurs in a very high-strike instrument when spot is much lower. I keep a small lower tail into the open-below bin (below -80%) representing a strong upside move with liquidation in very low strikes, and a small open-above tail (above 500%) for rare combinations of large strike/spot ratios plus a liquidation occurring in such an instrument.
An amateur forecast commonly (i) confuses this with option-price slippage or premium deviations (yielding single-digit answers), and/or (ii) ignores the ‘maximum absolute deviation over many events’ aspect, which pushes the distribution’s upper tail much higher than a typical liquidation’s deviation. My forecast explicitly models (a) the extreme-value selection, (b) the strike-vs-index mechanics from the resolution criteria, (c) asymmetry/bounds (floor at -100%, open right tail), and (d) the operational consideration that liquidations may concentrate in strikes that matter for margin (tempering the most extreme claims). Confidence is moderate because the dominant uncertainty is empirical: how often liquidation-flagged option trades occur in far-wing strikes on Deribit during such a window.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the dominant reasoning is that the signed strike-vs-index deviation is likely to be positive and right-skewed, with a meaningful chance of 0% if liquidation flags are missing or not preserved in the data.
Asymmetric option strike space
Liquidation mechanics
Data/flag uncertainty
The collective reasoning points to a strong positive skew, with the most likely non-missing outcome coming from a high-strike call liquidation rather than a put. Still, the forecasts retain a meaningful 0% fallback due to data limitations, and a smaller but real negative branch tied to crash-driven put liquidations.
— Iteration 2 — Across the forecasts, the dominant view is that the liquidated Deribit BTC option with the largest absolute strike-to-index deviation will most likely have a positive signed deviation—that is, it will probably be a far out-of-the-money call with a strike well above the BTC index.
The collective reasoning points to a positive signed deviation most likely, driven by the tendency for far-OTM call liquidations on Deribit BTC options to generate the largest absolute strike-index gaps. The distribution is expected to be asymmetric, with limited negative downside, substantial upside tail risk, and a non-trivial chance that no qualifying liquidation occurs at all.
— Iteration 3 — Across the forecasts, the core reasoning is consistent:
Positive deviations are favored over negative ones.
The main driver is the structural asymmetry in Deribit BTC options: calls can have strikes far above the index, while puts are limited much closer to spot. That means the largest absolute deviation is more likely to come from a high-strike call than from a low-strike put.
The maximum-absolute-deviation event is likely to be a deep out-of-the-money call liquidation.
Several rationales emphasize that if any liquidation occurs in the 28-day window, the biggest one by absolute deviation will probably be a call with a strike multiple of the index price, producing a large positive signed % deviation.
Negative outcomes are bounded and less extreme.
Put-driven liquidations can only generate deviations down toward about -100% at most in theory, and in practice likely somewhat less negative because listed put strikes are not extremely low. This makes the negative side less competitive for the “max absolute deviation” selection.
There is still meaningful uncertainty about whether a liquidation occurs at all.
One recurring caveat is that if there are no eligible liquidations, or if activity is unusually sparse, the realized outcome could be near zero or otherwise not strongly positive. Still, the prevailing view is that at least one liquidation is likely over a 4-week window.
The size of the positive tail is the main disagreement.
The forecasts differ mostly on how extreme the positive result could be: some expect a moderate positive deviation around +115% to +145%, while another sees a much larger central value around +318%. All allow for very large upside tails under sharp BTC price moves and very high-strike listings.
Bottom line: the collective reasoning points to a likely positive signed deviation, driven by call-strike asymmetry and the possibility of deep-OTM call liquidations, with the main uncertainty being how extreme that positive deviation will be.
Mathematical Asymmetry of the Deviation Formula The rationales universally agree that the mathematical structure of the deviation formula structurally biases the outcome toward a positive number. Because option strikes cannot fall below zero, the maximum absolute deviation for out-of-the-money (OTM) put options is strictly capped. Conversely, OTM call options have theoretically unbounded strike prices, allowing their absolute deviations to easily exceed the mathematical limits of puts. Since the question resolves based on the maximum absolute deviation, the liquidation of a single deep OTM call will almost certainly overpower any put liquidation, resulting in a heavily positive signed deviation.
Deribit’s Margin and Liquidation Mechanics Deribit’s incremental auto-liquidation system targets under-margined accounts to neutralize risk. Both Standard and Portfolio Margin accounts holding naked short OTM options are highly vulnerable to margin breaches caused by underlying asset price swings or sudden spikes in implied volatility (IV). When an account falls into deficit, the risk engine forcefully buys back these deep OTM “lottery ticket” calls, officially registering them as liquidations on the exchange.
Market Positioning and Strike Availability Forecasters note a massive concentration of open interest at extreme upper-wing call strikes. This is driven by retail and institutional traders selling deep OTM options to generate yield. Because the exchange previously minted highly elevated strikes during past market highs, options with strikes significantly higher than the current index price are actively held and remain prime targets for auto-liquidation.
Macroeconomic and Volatility Catalysts The resolution window overlaps with a dense cluster of expected volatility catalysts. These include major central bank interest rate decisions (FOMC, BOE, BOJ), key US economic data releases (Non-Farm Payrolls), and scheduled cryptocurrency bankruptcy estate distributions. This environment practically guarantees sudden market movements and IV expansions, making an absence of liquidations highly improbable and elevating the likelihood that extreme OTM calls will be liquidated.
Edge Cases While the overwhelming consensus points to a large positive outcome, the rationales acknowledge remote edge cases where the signed deviation could resolve negative or flat. This could only occur in the highly unlikely event that the liquidation engine completely bypasses illiquid high-strike calls—leaving a deep OTM put to claim the maximum absolute deviation—or in the unprecedented scenario where absolutely zero options are liquidated over the four-week period.

The research reviews July 2026 market context (MicroStrategy’s early-July sale of 3,588 BTC, elevated futures open interest near $20.6B, extremely positive perpetual funding spikes, and large recent leveraged liquidations) and options-market metrics (Deribit DVOL showing moderate expected volatility, put-to-call premium ~1.15, and Max Pain near spot). It also notes ETF flow dynamics (a June net outflow of ~$4.5B with a $223M inflow on July 3) and frames the market as fragile with crowded leverage that makes liquidations in a four-week window likely.
It then analyzes Deribit mechanics and the resolution formula ((Strike - Index) / Index * 100), emphasizing that only short options get liquidated and that cross-margin/portfolio margin liquidation can force closure of short positions into illiquid books. Mathematically, deep OTM puts are bounded at -100% while OTM calls are unbounded on the positive side; because market participants often sell very high-strike calls to pick up yield, the study concludes the maximum-absolute-deviation trade is overwhelmingly likely to be a deeply OTM Call. Using current strike availability and an assumed index range of ~$60k–$75k for the July 15–Aug 11 window, the research projects the signed percentage deviation for the max-absolute-deviation liquidated Deribit BTC option will be a positive number likely in the +100% to +300% range and recommends checking the highest available 2026 strikes (e.g., $150k–$250k) as candidates.

Hello! As your assistant, I have compiled a comprehensive rundown of the current market news, predictive metrics, and the underlying mathematical base rates to help you forecast this Metaculus question accurately.
To forecast Deribit option liquidations, we must first assess the current volatility and leverage in the crypto market leading into the July 15–Aug 11 window:
While there are no direct prediction markets (like Polymarket) trading on this hyper-specific Deribit API metric, we can anchor our expectations using options market data:
To generate a precise forecast, we must look at the mechanics of the Deribit risk engine and the mathematics of the resolution criteria:
1. How Options Liquidations Work on Deribit: Buyers of options cannot be liquidated (they only risk their initial premium). Therefore, only short (written) options can be liquidated [17]. Furthermore, Deribit heavily utilizes cross-margin (portfolio margin) [11][12]. When a trader gets liquidated—often because a heavily leveraged futures position moved against them—the risk engine forcefully closes all of their positions, including their short options, forcing orders into potentially illiquid order books.
2. The Mathematical Asymmetry of the Formula: The resolution formula is: ((Strike - Index) / Index) * 100 We are looking for the trade with the maximum absolute deviation, which means we want the largest distance from zero, whether positive or negative. However, the math creates a massive structural bias:
(10,000 - 60,000) / 60,000 = -83.3%. Because the lowest possible Strike is theoretically near $0, the absolute deviation for a put is mathematically capped at 100%.(200,000 - 60,000) / 60,000 = +233%. The absolute deviation for a call is mathematically uncapped.3. The “Outside View” Anchor: Because retail traders frequently sell extremely deep OTM options to harvest yield [12], and because portfolio liquidations drag these deep OTM options into the liquidation engine, the maximum absolute deviation is almost guaranteed to be a deeply OTM Call.
Given the formula’s mechanics, you should expect this question to resolve as a highly positive number. Unless absolutely no liquidations occur (which is incredibly rare for a 4-week window in a market with $20B+ in open interest and recent daily liquidations [2][6]), the maximum absolute deviation will stem from an out-of-the-money Call option with a strike price exponentially higher than the index price.
Base rates suggest you should look at the highest strike prices currently available on Deribit for 2026 expiries (e.g., $150,000 to $250,000 strikes). Assuming an index price hovering between $60,000 and $75,000 during the July/August window [14], your signed percentage deviation will likely land somewhere in the +100% to +300% range.
Conditioning on not annulled.
I accept the critic’s central point: the distribution should be pulled down from my earlier forecast because the liquidation sample is highly selected. Deribit’s liquidation process is incremental; it can stop after partial risk reduction, and standard-margin liquidations generally try futures/perps before options, calls before puts, and earlier expiries before later expiries, while USDC/cross/PM regimes target high maintenance-margin contributors rather than simply “farthest strike.” This makes “far-wing strikes exist” much weaker than “far-wing strikes will be liquidated.” (support.deribit.com)
I still think the sign and skew are right. The API resolution is feasible: Deribit’s trade endpoint includes instrument_name, index_price, and the optional liquidation field with "M", "T", or "MT" for liquidation-caused trades, and Deribit says public liquidation fields become available after a one-hour delay. (docs.deribit.com) The formula is mechanically asymmetric: high-strike options can create very large positive deviations, while negative deviations are bounded near -100%. Also, the market is big enough that “at least one BTC option liquidation in 28 days” remains my modal assumption: a recent Loris snapshot showed roughly 878 active BTC option instruments, about $23.2B notional OI, and $1.8B 24h notional volume. (loris.tools)
The main update is that the modal max should probably be a mid/high but not absurd strike. BTC is currently around $63k, and public positioning reports emphasize large OI around the July $80k call and Dec. 2026 $120k call, not primarily $250k–$400k strikes. (news.bitcoin.com) At $63k, strikes of $100k, $120k, and $140k imply about +59%, +90%, and +122%, respectively. That makes a median around +110% more plausible than +123% or +132%. The right tail stays fat because a single dust liquidation in a $200k–$320k strike, especially if BTC is lower during stress, can dominate the statistic.
New nuance I now weigh more: a BTC crash does not naturally force far-OTM short calls to be liquidated, since they become less risky; the crash path more naturally touches puts or futures-heavy portfolios. But because the formula ignores option type, high-strike puts can also resolve positive, and PM/cross/USDC liquidation rules still leave pathways to unusual far-strike liquidations. I also raise the boring/no-qualifying-option-liquidation mass slightly, but not dramatically.

I agree with the critic’s main correction: the forecast should not be “highest listed strike wins.” The resolving object is narrower: a BTC option trade that actually appears in REST historical trade data with liquidation: "M", "T", or "MT", using that trade’s own instrument_name and index_price. Deribit’s docs confirm the relevant trade fields include instrument_name, index_price, and an optional liquidation flag with exactly those values. (docs.deribit.com)
The critic is also right that liquidation mechanics reduce the odds of the deepest wing being touched. Deribit’s liquidation process is incremental; for BTC/ETH-settled standard-margin instruments, futures/perps are generally liquidated before options, calls before puts, and earlier expiries before later expiries. Portfolio-margin accounts can instead close risk-matrix contributors or delta-hedge with futures. So a high strike existing or having OI is much weaker than a high strike printing as a liquidation trade. (support.deribit.com)
I still defend the core positive-skew view. The sign formula ignores option type; a high-strike put and high-strike call score the same. But since negative deviations are capped near -100% while positive deviations can be much larger, even a modest chance of a high-strike liquidation dominates the right tail. With BTC currently in the low/mid-$60ks — Deribit’s index lookup showed about $63.3k, while Xoomar showed spot around $65.0k — a $120k strike gives roughly +85% to +90%, $140k gives roughly +115% to +121%, and $200k gives about +208% to +216%. (deribit.com)
Current market size still makes “some relevant option liquidation” more likely than not: Loris shows Deribit BTC options at roughly 878 active instruments, $23.22B notional OI, and $1.81B 24h notional volume, while Xoomar shows BTC options OI around 362k contracts, put/call ratio around 0.55, and DVOL around 38.8. That supports liquidation opportunity, but not necessarily a deep-wing liquidation. (loris.tools)
New insight I am incorporating: Deribit’s strike policy is explicitly dynamic, based on volatility, underlying price, liquidity, and demand, so stale or newly added high strikes remain a real tail risk. Linear BTC_USDC options also broaden edge cases if the resolver includes all BTC-base options. But the Strategy/MicroStrategy BTC sale is only a volatility/tail catalyst, not a direct reason to raise the median. (support.deribit.com)
So I am moving slightly downward in the center, adding more mass to negative / zero / low-positive outcomes, while keeping a fat but sub-1%-ish >500% tail. My rough implied view: ~3% no relevant option liquidation, ~6–7% at or below zero, ~0.3% below -80%, and under 1% above +500%.

Model’s Answer:
Step one: Understanding the metric
The signed deviation = ((Strike - Index) / Index) × 100. The strike is fixed from the instrument name; the index is BTC’s spot price at the moment of liquidation. The question asks for the single liquidation with the maximum absolute deviation across the entire July 15–August 11 window.
Step two: Characterizing the distribution structure
BTC is currently trading around $62,000. Deribit lists options spanning extremely wide strike ranges — from perhaps $20k puts to $300k+ calls. The maximum absolute deviation will come from whichever liquidation event involves the most extreme OTM strike relative to BTC’s price at that moment.
Negative deviations are bounded (max -100% if index went infinite), while positive deviations are unbounded — highly deep OTM calls can produce triple-digit deviations.
Step three: Identifying key assumptions and their failure probabilities
Assumption A: Most liquidations are in moderately OTM instruments, not extremely deep OTM strikes (failure probability ~40%). If deep OTM calls with $200k+ strikes get liquidated, positive deviations of 200-400% become plausible. The current call-heavy positioning and interest in $75k-$100k+ strikes makes this non-trivial.
Assumption B: The sign of the max-abs-deviation comes from a call (positive). Given call-heavy positioning, this is likely but uncertain. Probability of failure ~30% (where a deep OTM put dominates).
Assumption C: At least some BTC options liquidations occur in the 28-day window. Given the recent $600M+ liquidation event on July 1 and general activity, this is nearly certain (failure probability <5%).
Step four: Positive vs. negative reasoning
Low outcome scenario (deeply negative, around -60% to -80%): A massive put position at a very low strike (say $15k-$25k) gets liquidated, e.g., a hedge fund that sold deep OTM puts. With BTC at ~$62k, even a $25k strike gives only -60%. Probability ~10%.
High outcome scenario (200%+): A leveraged long position in far OTM calls (strikes $150k-$400k) forces liquidation. With BTC at $62k, $250k calls give +300%. The 28-day window and call-heavy market increases likelihood. Probability ~25%.
Step five: Calibrating the distribution
The 28-day window is meaningful — with multiple liquidation events per day, the single maximum across thousands of trades will pull toward extremes. The market is call-heavy, BTC has high volatility potential, and Deribit lists extremely deep OTM calls. I expect the median to fall around +60-80% (a moderately deep OTM call), with significant right skew.

Listed strike grid runs far beyond current index, creating an asymmetric payoff scale that favors large positive strike/index gaps over equally large negatives.
Downside deviations are bounded by the lowest available strike and by -100%, while upside deviations can multiply many-fold as listed strikes extend into the high hundreds of thousands.
Recent tape shows many forced trades clustered near spot but a single far-wing call liquidation already exceeded all negative events by absolute magnitude.
Volatility and order-book withdrawal compress liquidity and raise the likelihood that a small far-OTM position will execute at a large signed distance from index.
If index drifts lower during the window, any existing high-strike call liquidation will produce a larger positive deviation; if index rallies, positive deviations shrink and the most extreme event can move to a lower strike.
A rare liquidation of an ultra-high strike or a sudden index collapse are the primary inflection points that would push the maximum absolute deviation into the far-right tail.
The short historical sample and lack of account-level exposure data leave the tail mass and strike-probability allocation most uncertain.
Outcome sensitivity is highest to (1) which extreme strike is actually liquidated, (2) contemporaneous index moves at execution, and (3) the thinness of far-wing order-books.
Forecast: median signed deviation = 19.9891%
I treated this as an extreme-value question over all BTC option trades on Deribit with liquidation flags during 00:00:00 UTC on July 15, 2026 through 23:59:59 UTC on August 11, 2026. Deribit’s REST trade endpoints expose
instrument_name,index_price, and an optionalliquidationfield whose valuesM,T, orMTmark liquidation trades, so the prompt’s resolution mechanics line up with the exchange API. (docs.deribit.com)The market structure matters a lot. Deribit says liquidations are incremental and, assuming liquidity exists, are executed in real time at roughly one round per second. For BTC/ETH-settled standard-margin accounts, bought options cannot be liquidated; the engine first targets positions contributing to delta exposure, then futures/perpetuals before options, then calls before puts, then earlier expirations before later expirations. For portfolio margin, the engine instead analyzes which instrument contributes most to the margin/risk matrix, and Deribit explicitly notes that even a portfolio made up solely of long options can be liquidated. (support.deribit.com)
BTC inverse options currently span 1-4 dailies, 1-3 weeklies, 1-3 monthlies, and 1-4 quarterlies, and Deribit says it initially lists strikes around 0.1 to 0.9 delta while adding extra strikes as the underlying moves. BTC strike spacing is tighter in the front end and wider in the wings, with the quarterly policy using up to $10,000 wing increments. (support.deribit.com)
That means the realized maximum deviation is a contest between front-end liquidation ordering and the much wider long-dated strike universe. The right tail is especially important because Deribit’s portfolio-margin framework explicitly stress-tests extended moves of -66%, -33%, +50%, +100%, +200%, +300%, +400%, and +500%, which is exactly the sort of regime where far-wing options start to matter for liquidation/risk. (support.deribit.com)
As of July 7, 2026, a spot proxy for BTC is about $63,423. Deribit’s homepage snapshot today shows active BTC option volume in strikes such as 56k, 65k, and a Dec 25, 2026 120k call, while web-indexed Deribit pages show that at least a Sep 25, 2026 280k call exists; Deribit commentary earlier in the year also referenced fresh Dec 170k calls and Jun 40k puts. At the current spot, those example strikes map to about -11.70% (56k), +2.49% (65k), +89.21% (120k), +168.04% (170k), +341.48% (280k), and -36.93% (40k) deviations. (deribit.com)
Recent market context argues against a trivial distribution. A June 11, 2026 Deribit Insights note said BTC had fallen back toward the ~$60k area and that realized volatility had surged to 70, and Deribit’s Industry page shows a June 21 follow-up piece titled “Crypto Options Reset as Macro Support Meets Defensive Positioning.” That pushes me toward expecting at least some meaningful liquidation risk in the four-week window, though not certainty because inverse BTC liquidations in standard margin often stop after futures/perpetuals and earlier positions are reduced. (insights.deribit.com)
My base case is therefore: about a 14% chance of no qualifying BTC option liquidation at all (so the market resolves to 0), a moderate left tail from low strikes below index, a much larger mass on moderately positive outcomes from strikes above index, and a fat right tail because the contract universe already contains very high upside strikes and the question asks for the single liquidation with the maximum absolute deviation over four weeks. Because documented upside strikes currently extend much farther above spot than documented downside strikes extend below spot, I think the signed winner is more likely to be positive than negative. My best single-number estimate is +60%.
I treated the target exactly as written: the signed value of (Strike - Index) / Index * 100 for the single BTC option trade on Deribit with liquidation flag M, T, or MT that has the largest absolute deviation during 2026-07-15 through 2026-08-11. Deribit’s market-data docs confirm those liquidation flags on the public trade endpoints, and the public by-currency-and-time endpoint only returns the last 24 hours; Deribit’s support article says historical retrieval is supported on private user-history endpoints via a historical parameter, not as a simple public archive of flagged market-wide liquidations. That means there is no easy official public time series of comparable past BTC-option liquidation flags for me to fit directly, so I am keeping a wider-than-usual forecast distribution. (docs.deribit.com)
The liquidation mechanics matter a lot. Deribit says liquidations are incremental. For BTC/ETH-settled standard margin, positions that contribute to delta exposure are handled first, futures and perpetuals are liquidated before options, then calls before puts, and earlier expirations before later ones. For portfolio margin, Deribit says the engine analyzes the risk matrix and liquidates the instrument contributing most to margin requirements, with delta hedging via futures/perpetuals also possible. My inference from those rules is that the winning trade is more likely to be a strike that still matters for current delta or maintenance margin than a random ultra-far wing with negligible risk contribution. (support.deribit.com)
The market backdrop as of Tuesday, July 7, 2026 is mixed but calmer than the June stress episode. BTC is about 63,423 USD now. Deribit research described early June as a genuine breakdown phase, with BTC retreating to the 60k area, realized volatility surging to roughly 70, and a possible test of 50k if support failed. By June 17, BTC had bounced back above 67k and 7-day ATM implied volatility had fallen to around 33 percent, and by June 21 realized volatility had compressed back into the high-30s even while short-dated put skew stayed defensive. Deribit’s support statistics page shows May 2026 BTC option turnover of 643,963 contracts and about 50.31 billion USD notional, and the official homepage says Deribit has about 85 percent share of the BTC and ETH options market. From that combination, I infer that at least one BTC-option liquidation during a 28-day window is more likely than not, but not close to certain. (insights.deribit.com)
Strike structure also matters. Deribit lists 4 dailies, 3 weeklies, 3 monthlies, and 4 quarterlies for inverse BTC options, with strike spacing that ranges from 500 USD in the shortest tenors to 10,000 USD in 3-month wings, and it adds new strikes when spot trades above the highest or below the lowest listed strike. In March, Deribit commentary highlighted downside protection concentrated around 61k-64k and large open interest at 75k and 125k call strikes. On July 7, the official homepage’s high-volume list included BTC-10JUL26-56000-P, BTC-10JUL26-67000-C, and BTC-25DEC26-120000-C. Relative to current BTC at 63,423 USD, those are about -11.7 percent, +5.6 percent, and +89.2 percent away, while a 75k strike is about +18.3 percent away. This is why I think the right tail has to stay meaningfully open even though the center of the distribution should be much lower. (support.deribit.com)
My core judgment is that the modal winner should still be moderate rather than enormous. Because liquidation focuses on risk-contributing positions, the max-absolute trade is usually more likely to come from an active nearby wing or a moderately out-of-the-money strike with nontrivial delta or margin impact than from the single furthest long-dated strike on the board. I lean somewhat positive on sign: upside call strikes currently extend farther above spot than the visible downside hedge strikes extend below it, and the resolution rule also breaks exact absolute-value ties in favor of the positive side. But I do not want to overstate that tilt, because recent Deribit research still shows persistent defensive put skew and downside hedging, so a negative winner remains very plausible. (support.deribit.com)
So I encoded a mixture distribution with about 9 percent mass at exactly 0 for the no-liquidation case, a near-ATM or small-liquidation cluster around low single digits, a larger positive cluster centered in the low 20s, a smaller negative cluster centered in the low teens below zero, and thin tails for rare deep-crash-put or long-dated high-call liquidations. My best single-number estimate is +12.6 percent. That is deliberately far below the current +89.2 percent distance to the active Dec 120k call, because I think the max-absolute liquidation trade is much more likely to come from a nearer, more liquid, higher-delta strike than from the most extreme long-dated wing. (deribit.com)
I treated this as an extreme-value question: over all BTC option trades on Deribit during 2026-07-15 00:00:00 UTC through 2026-08-11 23:59:59 UTC, what is the most extreme strike/index ratio among trades explicitly flagged as liquidations. The relevant Deribit trade endpoint exposes instrument_name, index_price, and an optional liquidation field whose values are M, T, or MT, and Deribit’s inverse BTC option symbol format is BTC-DDMMMYY-STRIKE-SIDE, so the resolution variable is directly recoverable from the trade record itself. (docs.deribit.com)
The first thing I looked at was the strike universe that can even exist during the window. Deribit currently lists BTC options across 1, 2, 3, 4 dailies, 1, 2, 3 weeklies, 1, 2, 3 monthlies, and 1, 2, 3, 4 quarterlies, and says it introduces call strikes in roughly the 0.1 to 0.9 delta range and put strikes in the -0.1 to -0.9 delta range, adding new strikes as the underlying moves. For BTC, the strike ladder widens with maturity, up to 10,000 USD wing spacing at the 3-month bucket. That means the July 15-August 11 window can contain both very near-dated strikes and far OTM long-dated wings. (support.deribit.com)
Scale argues against assuming the answer will be trivial. Deribit’s own monthly statistics show 643,963 BTC option contracts traded in May 2026, representing 50,311,738,593 USD of BTC options turnover. So even if liquidation-flagged option trades are much rarer than ordinary trades, the exchange is large enough that a four-week window can plausibly produce at least one unusual options liquidation. (support.deribit.com)
At the same time, options liquidations are clearly less automatic than perp liquidations. Deribit says bought options on Standard Margin cannot be liquidated, and for Standard Margin liquidations involving BTC/ETH-settled instruments it generally liquidates delta-contributing positions first, futures and perpetuals before options, calls before puts, and earlier expiries before later expiries. On the other hand, Deribit also states that in Portfolio Margin even portfolios made up only of long options can be liquidated, and its PM risk matrix includes an extended table with stress moves such as -66%, -33%, +50%, +100%, +200%, +300%, +400%, and +500% specifically to account for large far-out-of-the-money short-option risk. My read is: BTC option liquidations are not guaranteed, but once they happen the tail can be quite wide, and there is a mild structural tilt toward upside-call prints showing up before equally deep puts in some liquidation paths. (support.deribit.com)
Current market context makes the positive tail more interesting than the negative tail. BTC is about 63,423 USD as of 2026-07-07. Deribit’s live site currently shows BTC-25DEC26-120000-C among active high-volume contracts, and Deribit-hosted market commentary from March highlighted large open interest at the 75k and 125k call strikes while also saying short-dated downside protection was concentrated around 61k-64k. At today’s BTC price, a 120k strike is a +89.20580861832458% deviation and a 125k strike is a +97.08938397742143% deviation. Recent June commentary on Deribit also described BTC as having fallen back to the 60k area, with discussion of a possible test of 50k, plus front-end downside hedging pressure. That combination matters: the downside strikes most clearly in focus are much closer to spot than the long-dated upside call strikes already visible in live trading and open-interest commentary. (asia.deribit.com)
I also sanity-checked this with the listing policy rather than relying only on visible strikes. Using Deribit’s 10-delta strike-introduction rule and the 2026 volatility regime described on Deribit-hosted research, a long-dated 10-delta call can easily land at a bit above 2x spot, while a comparable 10-delta put is much closer to about one-half to three-fifths of spot. That asymmetry is an inference from Deribit’s policy plus current spot/vol conditions, not a direct exchange statistic, but it lines up with the observed 120k/125k upside interest. (support.deribit.com)
Putting it together, my forecast has three main pieces. First, I leave a meaningful 12% point mass at exactly 0 for the case where no BTC option liquidation meeting the flag criteria occurs in the full window. Second, conditional on a nonzero resolution, I think the most likely winner is an upside call rather than a downside put, because the observable long-dated upside strikes are farther from spot than the downside strikes most clearly being discussed, and because Standard Margin liquidation order slightly favors calls over puts once options are reached. Third, I keep a fat right tail because Portfolio Margin explicitly recognizes extreme far-OTM option risk and because the question resolves to the single most extreme liquidation trade over nearly a month, not to a typical liquidation. My best point estimate is around +70%, with the median of my distribution also near that area, and with meaningful mass from roughly +50% to +110%, a smaller left tail centered around about -10% to -50%, and a thinner but real right tail beyond +150%. (support.deribit.com)
As of July 7, 2026, the resolution mechanics are straightforward. Deribit’s public trade-history endpoints expose instrument_name, index_price, and the optional liquidation flag, and the documented liquidation values are M, T, and MT. For inverse BTC options the symbol format is BTC-DDMMMYY-STRIKE-SIDE, and for linear BTC options it is BTC_USDC-DDMMMYY-STRIKE-SIDE, so the strike needed for resolution is recoverable from the instrument name while the relevant index comes from the same trade object. (docs.deribit.com)
Market context argues against an extremely high probability on 0. Recent Deribit monthly statistics show 643,963 BTC option contracts traded in May 2026, worth about $50.31B notional. A current market snapshot puts Deribit near $22.6B of BTC options open interest with about 13 expiries, 908 instruments, ATM IV around 31.6%, and a put/call ratio of 0.557. The July 15, 2026 to August 11, 2026 window also overlaps repeated expiry events: BTC options expire daily at 08:00 UTC, weekly on Fridays, monthly on the last Friday, and quarterly on the last Friday of the quarter; current OI is especially large around the July 17 and July 31 expiries. (support.deribit.com)
The biggest structural clue is strike geometry. Deribit says BTC strikes are introduced across roughly the 0.1 to 0.9 delta range and new strikes are added when the underlying moves beyond the highest or lowest listed strike. Official Deribit snippets currently show 30k and 35k puts plus 120k and 130k calls, and recent indexing shows a Sep. 25, 2026 140k call page and a 20k put page. With BTC at $63,423 today, those strikes correspond to about -52.69854784541885% for 30k, -68.46569856361256% for 20k, +89.20580861832458% for 120k, +104.97295933651829% for 130k, and +120.74011005471202% for 140k. So the visible upside wing is materially farther from spot than the visible downside wing. (support.deribit.com)
Liquidation rules strengthen that positive bias. On BTC/ETH-settled standard-margin accounts, bought options cannot be liquidated, futures and perpetuals are liquidated before options, and if Deribit does liquidate options it goes calls before puts and earlier expiries before later expiries. On portfolio margin it targets the largest risk contributors and can hedge delta with futures or perpetuals. That means option liquidations are less certain than futures liquidations, but when they do occur on inverse BTC books the rules lean somewhat toward calls. Combined with the current put/call ratio below 1, I think the max-absolute-deviation winner is more likely positive than negative. This sign call is an inference from the documented mechanics and the current surface, not a directly observed historical count. (support.deribit.com)
My distribution therefore leaves a discrete 9% mass at 0 for the no-BTC-options-liquidation case, about 13% on a negative winner centered on deep-put liquidations, and the remaining 78% on positive outcomes concentrated around roughly 90% to 120%, with a thinner right tail beyond that. I keep that right tail because Deribit commentary has previously discussed accumulation in Dec. 75k-150k calls, so extreme upside-wing strikes are not hypothetical. In plain English: I think the most likely resolution is that at least one BTC option liquidation occurs between July 15, 2026 and August 11, 2026, and the most extreme strike/index separation is more likely to come from a far-OTM call than from a crash put. (insights.deribit.com)
I could verify the resolution fields and the current chain context, but I could not directly enumerate the live historical liquidation tape from the REST API in this environment, so the event-rate part of the forecast is judgmental rather than backtested. (docs.deribit.com)
I interpret the question literally: resolve from BTC option trades on Deribit between 2026-07-15 00:00:00 UTC and 2026-08-11 23:59:59 UTC, consider only trade objects whose liquidation field is M, T, or MT, and compute deviation from the option strike embedded in instrument_name and the index_price in that same trade object. Deribit’s API docs confirm both the liquidation-flag semantics and that BTC inverse option names encode the strike in the BTC-DDMMMYY-STRIKE-SIDE format. (docs.deribit.com)
As of July 7, 2026, BTC spot was in the low-to-mid $60k area: the finance feed showed about $63.4k, while Deribit-linked option snapshots from July 4-7 showed spot around $65.0k-$65.9k. The BTC options complex on Deribit is large enough that I think a zero-liquidation month is possible but not the base case: a recent options dashboard snapshot showed roughly $20.4B of BTC option open interest, about 930 active instruments, and ATM IV near 27%, while expiry-level pages showed very large open interest in the main expiries, including 87,747 contracts on July 31, 2026, 87,974 on September 25, 2026, and 86,567 on December 25, 2026. Those same pages also show call-heavy positioning in key expiries, for example put/call OI of 0.39 on July 31 and 0.564 on December 25. (loris.tools)
Strike availability is asymmetric, but not unlimited. Deribit’s contract-introduction policy says BTC strikes are introduced around the 0.1 to 0.9 delta region, with tighter intervals for short expiries and wider intervals for longer expiries, and that new strikes may be added if price moves or user demand warrants it. In current snapshots, the July 17 expiry tops out at $70k, July 24 at $75k, July 31 at $120k, August 28 at $110k, and the longer-dated September 25, December 25, March 26, 2027, and June 25, 2027 pages reach $140k; the low end is $30k on September, December, and June, and $35k on March. Open interest is not just clustered near spot: July 31 has 6,954 calls at $80k, 1,798 at $100k, and 1,062 at $120k; September 25 has 2,266 calls at $125k, 1,435 at $130k, and 1,182 at $140k; December 25 has 6,017 calls at $120k and 1,437 at $140k. (support.deribit.com)
That asymmetry strongly favors a positive signed resolution. At a $65.9k index, a $120k strike is +82.09408194233687%, a $140k strike is +112.44309559939303%, and a $30k strike is only -54.47647951441578%. Even if BTC rallies to $80k, a $30k put is only -62.5%, while if BTC sells off to $55k a $140k call becomes +154.54545454545453%. So the maximum possible absolute deviation from currently listed strikes is materially larger on the positive side than on the negative side, and the question’s tiebreak rule also favors the positive sign.
However, I do not think the right answer is simply the current highest listed call wing. Deribit liquidations are incremental and stop once maintenance margin drops back below 100%. For BTC/ETH-settlement instruments in segregated standard margin, Deribit says futures and perpetuals are liquidated before options, calls before puts, and earlier expiries before later expiries; it also says bought options in standard margin cannot be liquidated. That matters because the earlier weekly expiries visible right now are much tighter than the long-dated wings: July 17 only reaches $70k and July 24 only $75k, while July 31 reaches $120k and August 28 reaches $110k. So the exchange’s own liquidation order biases the sign positive, but it also tempers how often the engine would have to reach the farthest-dated $140k wing before the account exits liquidation. (support.deribit.com)
I still leave a meaningful right tail because not every liquidation is on BTC-settled standard-margin accounts. Deribit’s support docs say cross-collateral and portfolio-margin liquidations are broader, can prioritize positions with the highest maintenance margin, and in PM accounts can analyze the risk matrix and close open options positions as part of the liquidation process. Also, short options are genuinely liquidatable exposures: for inverse options, long options in standard margin have no further margin requirement beyond premium paid, while short calls and short puts do carry maintenance margin. Since every open contract necessarily has a short side, the sizable open interest in $100k-$140k calls represents real short-option inventory that can appear in forced trades. (support.deribit.com)
Putting that together, my base case is: small exact-zero mass for no qualifying BTC option liquidations; a small negative tail for rare cases where the max-absolute trade is a low-strike put; but a clearly dominant positive distribution, centered below the raw current maximum of the $140k wing because of incremental liquidations and the preference for earlier expiries, yet still well above ATM because the question asks for the single liquidation with the maximum absolute deviation over almost four weeks. My central estimate is around +77%, with roughly a one-in-four chance the result is above +100%, and a smaller but real chance of +150% or more if a later-dated wing call is liquidated during a selloff or in a broader cross-collateral / portfolio-margin event. The CDF code encodes that view as a right-skewed mixture with 5% point mass at exactly 0.
