As of October twenty-first, twenty twenty-six, Volmex data showed that bitcoin options accounted for just under 60% of the cryptocurrency’s derivatives open interest last week, up from around 50% at the start of the year. The majority share marks a change in the market’s composition: contracts that can manage risk, generate income or express views on volatility now outweigh futures by this measure.
Key Takeaways
- Options represented a majority of bitcoin derivatives open interest, according to Volmex, rather than merely approaching that threshold.
- U.S. bitcoin ETF options held about $36 billion in open interest, with BlackRock’s IBIT accounting for nearly $35 billion.
- BlackRock has introduced an options-based income fund and filed for a buffer ETF; the latter remains a proposed offering.

What the Bitcoin options majority measures
The figures measure open interest—the value of contracts opened but not yet closed—not trading volume. Volmex’s comparison covers bitcoin futures, perpetual futures, crypto-native options and options tied to exchange-traded funds.
Volmex, the issuer of the bitcoin volatility index BVIV, described the growing options share as a structural shift toward risk management. Unlike a straightforward directional position, an option can express a view on price direction, the size of a move and when it will happen.
That flexibility matters for holders who want to hedge existing exposure or collect option premiums. Options also allow traders to position for a large move without borrowing, and their pricing reflects expected volatility. Their growing share does not, however, identify how much exposure represents hedging rather than speculation.

ETF contracts are a substantial part of the market
The snapshot as of the Friday preceding October twenty-first, twenty twenty-six, shows how ETF-linked contracts have become a substantial part of bitcoin options activity. They accounted for about 47% of options open interest, while Deribit remained the main venue in the broader options market.
Within the U.S. ETF segment, activity was heavily concentrated in IBIT. Its options open interest had tripled from about $11 billion in January 2025, reaching nearly the entire reported U.S. bitcoin ETF options total.
The figures below distinguish ETF options from the wider options pool and the full derivatives market. These are overlapping categories, not separate amounts to be added together.
BlackRock’s fund lineup shows the trade-offs
The change is also visible in product design. In June, BlackRock introduced the iShares Bitcoin Premium Income ETF, or BITA. It seeks monthly income by selling call options on a portion of its IBIT holdings, giving up some potential upside in return for premiums.
During the week of October twenty-first, twenty twenty-six, BlackRock also filed to offer a bitcoin buffer ETF. That proposed fund would use options to limit losses during a downturn while capping potential gains. The filing is distinct from a completed launch.
These strategies serve different objectives: BITA seeks income, while the proposed buffer fund targets limited downside. Neither offers those features without a corresponding restriction on participation in gains.
Conclusion
The clearest change is in the contracts investors hold: options now represent the larger share of bitcoin derivatives open interest. ETF-linked activity is a substantial contributor, with IBIT overwhelmingly dominant within the U.S. ETF options segment.
