Summary
Options are taking a growing share of bitcoin's derivatives market, a shift that Volmex, the issuer of the bitcoin volatility index BVIV, describes as a structural change in how the asset is traded. According to Volmex, options accounted for just under 60% of open interest among all bitcoin derivatives last week, compared with around 50% at the start of the year. Volmex argues this signals that trading bitcoin is increasingly about managing risk rather than simply betting on price direction.
Open interest data as of Friday illustrates the scale of the market. Options tied to U.S. bitcoin exchange-traded funds held 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 alone represent about 47% of the bitcoin options market, which is mainly concentrated at Deribit. IBIT options open interest has roughly tripled since January 2025, when it stood at about $11 billion.
The article notes that options let holders hedge positions, generate additional income, or take leveraged-free exposure to large moves, with positions able to last longer than leveraged perpetual bets. Options are priced on expected volatility, which is what indices such as BVIV measure. The trend parallels U.S. equities, where options on the S&P 500 accounted for nearly 75% of index-linked derivatives as of last year, according to the article.
BlackRock's product lineup reflects this demand. In June it launched 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 to offer a bitcoin buffer ETF that uses options to limit losses during a downturn while capping potential gains.
Volmex suggests bitcoin's volatility could continue to decline, a trend underway since spot bitcoin ETFs debuted in early 2024.
