BlackRock's Bitcoin ETF Achieves Significant Milestone, Solidifying Crypto's Mainstream Presence

A notable development occurred on Friday, marking the accelerated institutionalization of the bitcoin market, led by individual investors over the years. This is evident in the growth of options linked to BlackRock's bitcoin exchange-traded fund (ETF), IBIT, which has surpassed the total bitcoin options trading on Deribit, a major offshore player. The fact that IBIT options have closed the gap with Deribit's bitcoin options market in just two years is particularly striking, given that Deribit has been operating since 2016. On Friday, the dollar value of open IBIT options contracts on Nasdaq, also known as open interest, reached $27.61 billion, slightly higher than the $26.90 billion in Deribit's bitcoin options, according to data from Volmex. This milestone signifies that the regulated, institutional-grade bitcoin investment and derivatives infrastructure in the US is now on par with the offshore market. The rise of a booming, 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 growth 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 further 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 from 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 in scale, they differ in shape, revealing distinct trader sentiments. According to Volmex, the bulk 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 more conservative, with call open interest clustered around levels equivalent to approximately $106,000 in BTC terms. '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. 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 that depend on the settlement price of IBIT or spot BTC. Analysis suggests that IBIT options are approximately two months longer-dated on an OI-weighted basis, reflecting the underlying holder base of longer-horizon ETF investors onshore versus more tactical positioning offshore. 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. The rapid rise of IBIT in the options market is striking, and while it rivals Deribit in scale, the two are not direct substitutes, as IBIT options cater to regulated, onshore investors accessing bitcoin exposure through traditional 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.
