Key Takeaways
- • Options accounted for just under 60% of open interest across all bitcoin derivatives last week, up from around 50% at the start of the year, according to Volmex, issuer of the BVIV volatility index.
- • Options tied to U.S. bitcoin ETFs carried about $36 billion in open interest, with BlackRock's IBIT accounting for nearly $35 billion; the total options market reaches roughly $76 billion and the full bitcoin derivatives market about $129 billion.
- • IBIT options open interest has tripled since January 2025, when it was about $11 billion.
- • BlackRock expanded its options-based product lineup, launching the iShares Bitcoin Premium Income ETF (BITA) in June and filing this week for a bitcoin buffer ETF that caps both losses and gains.
- • Volmex argues the shift signals a structural move toward managing bitcoin risk rather than directional speculation, and suggests bitcoin volatility may keep declining.
Summary
Bitcoin options are taking a growing share of the cryptocurrency's derivatives market, a development Volmex, issuer of the bitcoin volatility index BVIV, characterizes as a structural shift toward risk management. According to Volmex, options accounted for just under 60% of open interest among all bitcoin derivatives last week, up from around 50% at the start of the year. Open interest measures the total value of contracts opened and not yet closed, and the market encompasses bitcoin futures, perpetual futures, and both bitcoin-native and ETF-based options.
As of Friday, options tied to U.S. bitcoin spot ETFs had about $36 billion in open interest, with BlackRock's IBIT accounting for nearly $35 billion. Including options on crypto-native platforms raises the figure to roughly $76 billion, and adding bitcoin futures, including perpetual and dated contracts, brings the overall market to about $129 billion. ETF options now represent about 47% of the bitcoin options market, which is mainly owned by Deribit. IBIT options open interest has tripled since January 2025, when it stood at about $11 billion.
The article draws a parallel with U.S. equities, where options on the S&P 500 Index accounted for nearly 75% of index-linked derivatives as of last year. Options allow holders to hedge holdings, generate additional income, or position for large moves without borrowing, and their longer expiries make them less susceptible to the funding pressures of leveraged perpetual positions.
BlackRock's product lineup reflects the trend. In June the firm introduced the iShares Bitcoin Premium Income ETF (BITA), which seeks monthly income by selling call options on a portion of its IBIT holdings, trading some upside for option premiums. This week BlackRock filed for a bitcoin buffer ETF that uses options to limit losses during a downturn while also capping potential gains.
CoinDesk notes that these developments suggest bitcoin's volatility could continue to decline, a trend underway since spot bitcoin ETFs launched in early 2024.
