Key takeaways:
- Roughly half of the $6 billion in Bitcoin options open interest is concentrated in low-probability trades commonly used for hedging and market-neutral strategies.
- Meanwhile, the 9% premium on put (sell) options suggests that professional traders remain cautious about the risk of a Bitcoin price decline.
Bitcoin (BTC) bulls are pinning their hopes on the massive Dec. 25 year-end options expiry, where nearly $6 billion in contracts is set to mature. A 33% rebound from the Feb. 6 yearly low of $60,130 has helped revive bullish sentiment across the market. Still, the large concentration of call (buy) options targeting $115,000 and beyond by Dec. 25 is raising concerns that traders may be becoming overly optimistic.

Bitcoin options on Deribit account for 92% of December’s total open interest, representing roughly $5.5 billion in contracts. Still, the amount ultimately settled at expiry is expected to be far smaller, as many of these positions were designed as hedges or market-neutral trades that do not rely on major price swings to generate returns.
Call (buy) options continue to heavily outweigh put (sell) options on Deribit, with puts trailing by 56%. That imbalance is not unusual in crypto markets, where traders generally maintain a bullish bias. Even so, the $1.85 billion in open interest tied to call options targeting $115,000 and above stands out. The positioning highlights the need to compare just how aggressive bullish bets are relative to bearish ones.

The large concentration of put options targeting $55,000 and below is equally striking, with open interest reaching nearly $1 billion. As a result, both bullish and bearish positions contain a similar share of low-probability bets, accounting for about 50% of the open interest on each side. In other words, if bulls are being criticized for excessive optimism, bears appear just as extreme in their downside expectations.

In addition to acting as a hedge within strategies that use different expiry dates, a $120,000 call option gives traders relatively inexpensive exposure to a major upside move. Based on Deribit pricing on May 7, investors could pay $2,202 for unlimited upside exposure tied to one full Bitcoin if its price reaches $120,000 or more by Dec. 25.
To better understand how professional traders view potential upside and downside risks, analysts often turn to the options skew metric, which offers a clearer picture of market sentiment and risk appetite.

Put options are currently trading at a 9% premium over comparable call options, reflecting moderate concern among traders about potential downside risk in Bitcoin. In a balanced market environment, the options skew indicator typically stays within a range of -6% to +6%. Despite Bitcoin’s rally toward $80,000, derivatives data suggests investor sentiment did not become significantly more euphoric.
As a result, the $1.85 billion in December call options should not necessarily be viewed as evidence of excessive bullish speculation.
