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

A significant development occurred on Friday, marking a milestone in the accelerating institutionalization of the bitcoin market, which has long been driven by individual investors. This is because options linked to BlackRock's bitcoin exchange-traded fund (ETF), IBIT, have grown to surpass total bitcoin options trading on the offshore platform 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 dollar value of open IBIT options contracts on Nasdaq, known as open interest, reached $27.61 billion, slightly higher than Deribit's $26.90 billion in bitcoin options, according to data from Volmex. This achievement indicates that the US's regulated, institutional-grade bitcoin investment and derivatives infrastructure 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, 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 investors can access regulated leverage and options exposure through iShares Bitcoin Trust (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 to measure 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, allowing 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 positioning, revealing 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, Deribit options positioning is bullish but more measured, indicating expectations of a rally to $106,000. 'Onshore call open interest 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 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 October 2026 expiries are preferred in IBIT, while August expiries dominate on Deribit. 'IBIT options are approximately two months longer-dated on an open interest-weighted basis, reflecting the underlying holder base of longer-horizon ETF investors onshore versus more tactical positioning offshore,' Volmex observed. Lastly, IBIT's implied volatility is higher than the implied volatility derived from Deribit's BTC options, which Volmex attributes to a structural quirk where ETF holders cannot easily short bitcoin directly, leading to demand for put options and elevated implied volatility. 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, with IBIT options catering to regulated, onshore investors and Deribit remaining 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 feeds into the broader ecosystem, and venues like Deribit benefit from increased sophistication and flow,' Fariq said.
