BlackRock's Bitcoin ETF Achieves Major Milestone, Marking Mainstream Crypto Acceptance

A significant development occurred on Friday, highlighting the accelerating institutionalization of the bitcoin market, which has been driven by individual investors for years. This is due to the growth of options linked to BlackRock's bitcoin exchange-traded fund (ETF), IBIT, which have become more prominent on Nasdaq than total bitcoin options trading on Deribit. Notably, IBIT options have closed the gap with Deribit's bitcoin options market in just two years, despite Deribit's head start since 2016. On Friday, the open interest (OI) of IBIT options contracts on Nasdaq reached $27.61 billion, surpassing Deribit's bitcoin options open interest of $26.90 billion, according to data from Volmex. This milestone indicates that the regulated, institutional-grade bitcoin investment and derivatives infrastructure in the US is now on par with the offshore market. Furthermore, a thriving, regulated market in the US could encourage more Wall Street institutions to explore digital assets, 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. "US retail investors can access regulated leverage and options exposure through IBIT options, which is supported by the current macro environment of supply chain uncertainty, energy shocks, and geopolitical risks, driving demand for hedging and options strategies," Fariq stated. 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. The two markets, though similar in scale, differ in shape, revealing distinct trader sentiments. According to Volmex, the bulk of open interest in IBIT call options suggests expectations of an ETF rally to levels equivalent to BTC trading at $109,709 in the near-term, approximately 41% higher than the current market price. In contrast, Deribit options positioning is bullish but more measured, indicating expectations of a rally to $106,000. "Onshore call OI is concentrated roughly 4 percentage points further out-of-the-money than offshore, and the onshore average delta is slightly lower, consistent with onshore flow being dominated by retail upside speculation and systematic call overwriting programs," Volmex noted. ETF holders tend to be more patient, with options expiring in October 2026 being preferred in IBIT, while August expiries dominate on Deribit. Lastly, IBIT's implied volatility is higher than Deribit's, which Volmex attributes to a structural quirk where ETF holders cannot easily short bitcoin directly, leading to increased demand for put options and elevated implied volatility. Overall, IBIT's rapid rise in the options market is striking, and it 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. "I don't see this as competition; it expands the market. As more participants become comfortable trading options via IBIT, it ultimately benefits the broader ecosystem, and venues like Deribit benefit from increased sophistication and flow," Fariq said.
