BlackRock's Bitcoin ETF Reaches Major Milestone, Solidifying Crypto's Mainstream Status

A significant development occurred on Friday, marking the acceleration of bitcoin's institutionalization, a market that has been driven by individual investors for years. This milestone was achieved as options linked to BlackRock's bitcoin exchange-traded fund (ETF), IBIT, surpassed the total bitcoin options trading on Deribit, a major offshore player, in terms of open interest on Nasdaq. Notably, IBIT options have bridged the gap with Deribit's bitcoin options market, which has been in operation since 2016, in just two years. On Friday, the open interest in IBIT options contracts on Nasdaq stood at $27.61 billion, slightly higher than Deribit's $26.90 billion, according to data from Volmex. This achievement signifies that the US's regulated, institutional-grade bitcoin investment and derivatives infrastructure is no longer secondary to the offshore market. Furthermore, a thriving, regulated market in the US could encourage more Wall Street institutions to explore digital assets, ultimately leading to more mature price discovery. Deribit's Global Head of Retail Sales and Business, Sidrah Fariq, views IBIT's rise as a positive development for the broader crypto derivatives ecosystem, stating that it provides US retail investors with direct access to regulated leverage and options exposure. Fariq attributes this demand to the current macro environment, characterized by supply chain uncertainty, energy shocks, and geopolitical risks, which drives the need for hedging and options strategies. Options are derivative contracts that grant the purchaser the right to buy or sell the underlying asset at a predetermined price at a later date. Analysts use open interest as a measure of market size and participation, with higher open interest indicating a deeper and more liquid market. Traders utilize options to hedge existing positions, speculate on price direction, and generate income on coin or ETF holdings. One popular income-generating strategy involving IBIT ETF and IBIT options is the covered call strategy, which allows investors to profit from BTC's implied volatility by holding the ETF and shorting IBIT calls at levels above the ETF's current market price. Although the two markets now match each other in scale, they are positioned differently, revealing distinct trader sentiments. According to Volmex, the majority of open interest in IBIT call options is concentrated at strike levels equivalent to bitcoin trading around $109,709, roughly 41% above the current price. In contrast, positioning in Deribit options is slightly more conservative, with call open interest clustered around levels equivalent to approximately $106,000 in BTC terms. Volmex notes that onshore call open interest is concentrated roughly 4 percentage points further out-of-the-money than offshore, consistent with onshore flow being dominated by retail upside speculation and systematic call overwriting programs. Put positioning is largely aligned across venues, with open interest concentrated around the $63,500 strike. ETF holders tend to be more patient, with options having expiry dates and contracts being settled based on IBIT or spot BTC prices at that time. Analysis of activity across both markets suggests that IBIT options are approximately two months longer-dated on an open interest-weighted basis. Lastly, IBIT's implied volatility is higher than the implied volatility derived from Deribit's BTC options, which Volmex attributes to a structural quirk: ETF holders cannot easily short bitcoin directly, so they buy put options as their only available hedge, keeping IBIT's implied volatility slightly elevated. Overall, IBIT's rapid rise in the options market is striking and now appears to rival Deribit in scale, although the two are not direct substitutes, as IBIT options primarily cater to regulated, onshore investors accessing bitcoin exposure through traditional brokerage channels, while Deribit remains the go-to platform for global investors.
