Bitcoin options are capturing the attention of traders as they gear up for the year-end $8.8 billion options expiry, scheduled for December 26. Intriguingly, more than $1 billion in Bitcoin options would come into play if Bitcoin’s price surpasses $200,000. But what are the real odds of this happening, and what do traders actually expect?
Understanding Bitcoin Options for a Year-End Rally
Currently, call options dominate, with total open interest standing at $6.45 billion compared to $2.36 billion in put options. Despite this, bearish traders seem comfortable with Bitcoin remaining below $120,000. Some call options have strike prices set at $170,000 or higher, which will expire worthless unless Bitcoin gains 46% from its current level. This shows that while there is optimism, expectations for a massive Bitcoin rally are measured.
Call Diagonal Spread Strategy
Professional traders often employ highly bullish call options as part of strategies that don’t rely on a 70% year-end rally. One such strategy is the Call Diagonal Spread. This involves buying a $200,000 December call and selling a $200,000 call with an earlier expiry, typically in October. The strategy profits most if Bitcoin exceeds $146,000 by October 31, as the long-dated call appreciates while the short-term call expires worthless. However, Bitcoin prices above $200,000 could negatively impact this strategy.
Inverse Call Butterfly Strategy
Another strategy is the “Inverse Call Butterfly,” which involves buying one $140,000 call, selling two $160,000 calls, and buying one $200,000 call—all with December expiries. This position profits most if Bitcoin lands near $160,000 on December 26, netting a substantial profit. However, losses begin if Bitcoin climbs past $178,500, though the $200,000 call helps cap potential losses.
Market Sentiment and Probability
The presence of nearly $900 million in put options targeting $50,000 to $80,000 for December shows that bearish bets are also in play, albeit with lower odds. For instance, the $140,000 call is priced around BTC 0.051, implying a 21% probability based on the Black-Scholes model, while the $200,000 call has an implied probability below 3%. Although these aggressive strike prices may grab attention, they are primarily tools within structured strategies offering limited risk and leveraged upside.
Unlike the options market, Polymarket indicates a 13% chance of Bitcoin reaching $200,000 this year. Traders are not betting everything on a 72% rally; instead, they’re using strategic approaches to maximize potential gains with minimized risks.
