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

A notable development occurred on Friday, indicating the accelerated institutionalization of the bitcoin market, which has long been driven by individual investors. This is evident in the growth of options linked to BlackRock's bitcoin exchange-traded fund (ETF), IBIT, which have become slightly larger on Nasdaq than the total bitcoin options trading on the offshore platform Deribit. It is striking that 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 dollar value of open IBIT options contracts on Nasdaq, also known as open interest, reached $27.61 billion, surpassing the $26.90 billion in Deribit's bitcoin options, according to data from decentralized crypto volatility protocol Volmex. This milestone signifies that the regulated, institutional-grade bitcoin investment and derivatives infrastructure in the US 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. 'US retail cannot easily access platforms like Deribit, so iShares Bitcoin Trust (IBIT) options provide them with direct access to regulated leverage and options exposure. This is further supported by the current macro environment, with supply chain uncertainty, energy shocks, and broader geopolitical risks, which naturally drives demand for hedging and options strategies,' Fariq told CoinDesk. 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 additional 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 simultaneously 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 sentiment. 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, roughly 41% higher than the current market price. In contrast, positioning in Deribit options is bullish but slightly more measured, indicating expectations of a rally to $106,000. The onshore call open interest is concentrated further out-of-the-money than offshore, with a slightly lower average delta, consistent with onshore flow being dominated by retail upside speculation and systematic call overwriting programs. ETF holders tend to be more patient, with options expiry dates extending to October 2026, while Deribit's expiries are more concentrated in August. Lastly, IBIT's implied volatility is higher than Deribit's, which Volmex attributes to the demand for put options from ETF holders who cannot easily short bitcoin directly. Overall, IBIT's rapid rise in the options market is striking, and it now appears to rival Deribit in scale. However, 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. If anything, it expands the market. As more participants get comfortable trading options via IBIT, it ultimately feeds into the broader ecosystem, and venues like Deribit benefit from increased sophistication and flow,' Fariq said.
