BlackRock's Bitcoin ETF Achieves Major Milestone, Signaling Widespread Adoption of Crypto

A significant development occurred on Friday, marking the accelerating growth of institutional involvement in the bitcoin market, which has long been driven by individual investors. This is evidenced by the fact that options linked to BlackRock's bitcoin exchange-traded fund (ETF), IBIT, have surpassed the total bitcoin options trading on Deribit, a major offshore player. 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, slightly exceeding the $26.90 billion in Deribit's bitcoin options, according to data from Volmex. This milestone indicates that the US is no longer secondary to offshore markets in terms of regulated, institutional-grade bitcoin investment and derivatives infrastructure. The growth of a 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, providing US retail investors with direct access to regulated leverage and options exposure. Options are derivative contracts that grant the purchaser the right to buy or sell an 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 use 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 sentiment. According to Volmex, the bulk of open interest in IBIT call options is concentrated at strike levels equivalent to bitcoin trading around $109,709, or roughly 41% above the current price. In contrast, Deribit options positioning is more conservative, with call open interest clustered around levels equivalent to roughly $106,000 in BTC terms. Additionally, IBIT options have expiry dates, with October 2026 expiries being preferred, whereas August expiries dominate on Deribit. Volmex notes 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, attributed 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 while it may rival Deribit in scale, the two are not direct substitutes, catering to different investor bases and markets.
