Bitcoin options market volatility: $1.4 billion in put bets reveal downside and negative gamma risks

In early April 2026, the Bitcoin options market showed a series of noteworthy anomaly signals. According to Deribit’s position distribution data, both the put options around a $60k strike price and the call options around an $80,000 strike price accumulated about $1.4 billion in notional open interest, forming a large-scale “troop deployment” pattern at both ends of the price range. Meanwhile, Bitcoin’s implied volatility continued to trend downward: 30-day implied volatility first dipped below 50% since February. Between conservative positioning in the options market and the price rebound in the spot market, a divergence is forming that is worth watching warily.

What does the core meaning of this divergence imply? What kind of risk is the “smart money” trying to prevent? Is the market preparing for a deep pullback, or is it only carrying out routine hedging within a range-bound environment? This article will systematically break down the anomaly signals in the current options market and their possible transmission paths from four dimensions: data, structure, sentiment, and scenario analysis.

Based on Gate market data, as of April 7, 2026, the Bitcoin price was $68,811.9, with a 24-hour trading volume of $13.3k, a market cap of approximately $1.33 trillion, and a market share of approximately 55.27%. The price change over the past 24 hours was -0.5%.

Deribit’s Position Distribution Shows Structural Imbalance

The Bitcoin options market has recently exhibited a typical “heavy positions at both ends” structure. On the Deribit platform, the total open interest for put options with target prices below $60,000 has reached about $1.44 billion. Although some of the bets at extreme strike levels (such as $40,000 and $45,000 strike puts) may belong to calendar strategies or components of ratio spread combinations and therefore may not represent pure speculation on a price collapse, the defensive tendency of the overall put option positioning is still very clear.

At the same time, the open interest of put options with target prices at $72,000 and above is also about $1.15 billion. This scale is enough to offset the strength of existing call options. In the options market, defensive positioning of puts is being significantly strengthened. The gap between implied volatility and realized volatility remains persistent: the former stays in the 48% to 55% range, while realized price volatility is relatively restrained.

More worth noting is that this defensive setup is not an isolated phenomenon. The total open interest in the Bitcoin futures market has also been contracting, and the funding rate once entered negative territory. Overall, the derivatives market is transitioning from the bullish structure of the past few months toward a more balanced, and even more defensive, direction.

A Structural Turning Point: From Calls to Defense

To understand the anomaly in the current options market, it is necessary to look back at how the Bitcoin market structure has evolved over the past three months.

From February to early March 2026, Bitcoin traded around $75k to $76,000. Market sentiment was relatively optimistic overall, and the proportion of call option positioning was relatively higher. After mid-March, the spot price began to pull back, but there was no clear sign of profit-taking. Meanwhile, the flow of options market positioning started to change—traders began systematically buying put options and setting up put spread combinations expiring from March to April.

In the last week of March, defensive signals were further reinforced. The market saw a large number of out-of-the-money “crash puts” structures, including $55,000/$60,000 put options expiring in March, as well as $50,000 put options expiring in April. At the same time, some traders used combination strategies of “selling call options” financed to “buy put options” for hedging—for example, a $62,000 put option expiring in April was hedged using funds from selling an $85,000 call option.

On April 3, 2026, Bitcoin and Ethereum experienced an options expiration event of about $14 billion—one of the largest derivatives expiration events of the 2026 fiscal year. After expiration, a clear bearish shift emerged among the largest participants. Whale accounts began aggressively shifting toward protective put options. In early April, the proportion of put option trading volume continued to rise: on Deribit, the share of put option成交量 within 24 hours reached 54.87%, while calls were 45.13%.

Entering the second week of April, the most actively traded contract in the options market evolved into a put option expiring on April 24 with a $62,000 strike. Its trading volume significantly led other contracts. Bitcoin implied volatility continued to fall, first breaking below the 50% level since February.

From Position Distribution to Volatility Pricing

Options Position Distribution: A Duel Structure with Heavy Positions at Both Ends

The most striking feature of the current Bitcoin options market is heavy positioning at both ends. On Deribit, puts near the $60,000 strike and calls near the $80,000 strike each hold about $1.4 billion in notional open interest. This structure implies that market participants are highly divided in their assessment of the future direction: one portion of funds is buying $80,000 strike call options, betting on an upside breakout; another portion is heavily buying put options near $60,000, providing hedging protection for downside moves.

Notably, in terms of the absolute value of open interest, the call option share (56.71%) is still higher than puts (43.29%), but actual trading volume shows the opposite tendency—put option trading volume share is 54.87%, clearly higher than call options’ 45.13%. This divergence—“a long-biased position structure but a short-biased flow”—typically indicates that the market is switching from existing positioning to incremental defensive positioning.

From the perspective of Max Pain, Deribit’s largest pain point for the April 24 expiration concentrates at around $70,000, which is about $3,000 to $4,000 higher than the current spot price. In historical experience, when the spot price is below the max pain point, market makers and large participants may have incentives to push the price back toward the settlement region as expiration approaches. To a certain extent, this reduces the probability of a rapid, short-term crash, but it also means the spot price faces a pull toward that region.

Implied Volatility Breaks Below 50%: A Shift in Pricing Logic

Bitcoin implied volatility (BVIV) first fell below 50% since February. 30-day implied volatility remains in the 48% to 55% range. A decline in implied volatility means the options market’s expectations for future price volatility are narrowing, but this does not equate to reduced market risk.

On the contrary, the persistent gap between implied volatility and realized volatility suggests a contradictory structure: traders are paying a premium for downside protection even if the spot market looks calm. This combination of “low realized volatility + relatively higher implied volatility” indicates that the market is pricing tail risk rather than making aggressive bets on short-term direction.

The Put Skew (put risk reversal) remains at a relatively high level, showing that market participants are still paying an excessive premium for downside risk. When implied volatility declines but Put Skew stays elevated, it usually means the demand for downside protection has not weakened due to the volatility drop.

Negative Gamma Environment: A Trigger Mechanism for Structural Risk

Below $68k, the market has already formed a “negative gamma” environment. In this region, market makers who sold put options face forced adjustments to risk exposure. When the price falls, market makers need to sell additional Bitcoin to hedge their short put positions.

This dynamic forms a self-reinforcing feedback loop: price drops → market makers are forced to sell → selling further pushes down the price → triggers more hedging demand. If Bitcoin breaks below $68,000, these hedging flows may shift from selling pressure into accelerated selling pressure, creating a chain reaction.

Glassnode data shows that market makers carry heavy negative gamma risk in the $68,000 to $50,000 range. Within this range, any downward price break could trigger systemic hedging actions by market makers, causing the price to accelerate toward the $60,000 level in the short term.

Three Main Lines of Market Divergence

There is a clear divergence of views regarding how to interpret the anomaly signals in Bitcoin options. Mainstream views mainly revolve around the following three lines.

Defensive positioning dominates: a “fragile equilibrium,” not “healthy digestion”

Bitfinex’s latest report defines the current market as a “fragile equilibrium,” not healthy consolidation. The core argument is that spot buy-side momentum has visibly cooled: corporate institutions, previously viewed as stable buyers, have recently shown reduced participation. Although there are still enterprises accumulating on dips, some institutions have chosen to take profits and close positions at higher levels, and clear divergence has emerged across institutional strategies.

Within this framework, the current Bitcoin range-bound action resembles a temporary equilibrium state rather than a convincing display of strong consolidation. With weakening spot demand, differentiated institutional buying, and increased defensive positioning in the options market, behind the apparent price stability lies the risk of volatile swings exceeding expectations.

Negative gamma structure amplifies downside risk; market makers may become a source of sell pressure

A second view focuses on the derivatives structure itself. Analysts generally believe that the negative gamma range formed below $68,000 is the largest structural risk source in the current market. Market makers that have sold downside protection options need to sell additional Bitcoin to hedge their risk when prices fall. This process could amplify a normal pullback into accelerated selling.

Recently, there has been about $247 million in long-position liquidations, but analysts believe the overall positioning adjustment is still insufficient. Under the existing structure, if key support levels collapse, Bitcoin could quickly probe toward the $60,000 level.

Volatility pricing divergence: implied volatility falling does not mean risk has cleared

A third view focuses on the divergence between implied volatility and realized volatility. Current implied volatility stays in the 48% to 55% range, but the realized price move has been relatively limited. This discrepancy suggests that traders are willing to pay a premium for hedging, even if the spot market appears calm.

From the perspective of volatility pricing, the combination of falling implied volatility and a sustained high Put Skew usually means the market is dealing with pricing uncertainty but has not entered an out-of-control panic state. To a certain extent, this lowers the probability of a sudden cascade of liquidation triggers. However, it also means that direction and tail risk tilt to the downside, which may present as a phase characterized by “weak oscillation dominated by protection.”

Industry Impact Analysis: Derivatives Structure Is Rewriting Price Transmission Mechanisms

The anomalies in the current options market are not just a trading-layer signal—they are changing the underlying mechanisms of Bitcoin price transmission.

First, the pricing weight of the derivatives market is increasing. The total amount of Bitcoin options open interest has surpassed $30 billion, and the impact of structural changes in the derivatives market on spot prices has become significantly stronger. Factors that were previously limited to professional trading circles—gamma hedging, max pain gravity, and market maker position adjustments—are becoming core variables driving short-term market direction.

Second, the divergence between spot demand and derivatives defense increases market fragility. On the spot side, corporate buy-side momentum is cooling, and some institutions have started shifting from accumulation to profit-taking. On the derivatives side, put option trading volume continues to exceed call option volume. When the spot market’s buyer base is shrinking while the derivatives market’s defensive positioning is increasing systemic sell pressure, the market’s equilibrium point becomes even more fragile.

Third, changes in volatility pricing are reshaping the choice of trading strategies. After implied volatility breaks below 50%, the attractiveness of directional trading declines. Strategies that enhance returns and volatility arbitrage strategies begin to show relatively more value. This shift suggests that the market may move from a “directional duel” phase into a “structural duel” phase.

Multi-Scenario Evolution Projections

Based on the current options market positioning structure, volatility pricing, and negative gamma environment, multiple scenarios can be used to project future price movements. It should be made clear that the following content is a projection based on existing data models and does not constitute a certain judgment about future direction.

Scenario 1: Range-bound consolidation continues

If spot demand holds at current levels and corporate buying and institutional accumulation behavior do not undergo large-scale reversal, Bitcoin’s price could continue to oscillate in the $64,000 to $74k range. In this scenario, the max pain point (around $70,000) will play a role in pulling the price back, limiting large deviations. The defensive put option positioning will continue to serve a hedging function, but it will not trigger a chain reaction of negative gamma.

Scenario 2: Upside breakout attempts resistance

If the macro environment improves or market sentiment warms, Bitcoin’s price could test the supply-dense area around $74k to $75,000. What needs to be watched is that around $74,000 there is a large amount of potential sell pressure. Investors who bought at high levels have a strong desire to reduce exposure in this area, which will significantly cap upside space. In addition, if the price breaks upward, the recently accumulated short positions may face squeezing, potentially triggering a period of short-covering rallies.

Scenario 3: Break below $68,000 triggers a negative gamma chain reaction

If the spot price breaks below $68,000, the negative gamma environment may be activated. As prices fall, market makers need to sell additional Bitcoin to hedge their short put positions. This hedging action turns into additional sell pressure, forming a self-reinforcing downward cycle. In this scenario, the price could accelerate in the short term toward the $60,000 level. About $247 million in long positions has already been liquidated recently; if this process accelerates, it may trigger larger-scale liquidation cascades.

Scenario 4: External shocks trigger tail risk

External shocks (such as macroeconomic data exceeding expectations, changes in regulatory policy, geopolitical events, etc.) could become catalysts that break the current fragile equilibrium. In this scenario, the presence of the negative gamma structure would amplify the impact of the external shock. Notably, Bitcoin and the Nasdaq 100 index show a high correlation (about 90%). Volatility in technology stocks would transmit to the Bitcoin market through the risk appetite channel.

Conclusion

The signals currently released by the Bitcoin options market are not a simple warning in a single direction, but a complex combination of structural signals. The $1.44 billion 60,000 strike put open interest and the $1.4 billion 80,000 strike call open interest together outline a pattern of deploying forces at both ends of the price. The combination of implied volatility breaking below 50% and Put Skew staying high suggests that while the market is narrowing directional bets, it has not relaxed its vigilance toward tail risk.

The negative gamma environment below $68,000 is the weakest link in the current market structure most worth focusing on. The existence of this structure means that once the price breaks through a key support level, the downward trend may no longer evolve at a linear speed—it could accelerate under the push of hedging flows.

For market participants, understanding the shift in options market structure is more important than simply tracking price movement. The derivatives market’s position layout and volatility pricing are redefining Bitcoin’s price transmission mechanism. With the spot buy-side base narrowing and defensive positioning in derivatives increasing, the market’s fragility may be far higher than what price action alone suggests.
