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

A significant development occurred on Friday, indicating the rapid growth of institutional investment in the bitcoin market, which has been driven by individual investors for years. This is evident in the fact that options linked to BlackRock's bitcoin exchange-traded fund (ETF), IBIT, have surpassed the 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 open interest in IBIT options contracts on Nasdaq reached $27.61 billion, exceeding the $26.90 billion in Deribit's bitcoin options. This milestone signifies that the US's regulated, institutional-grade bitcoin investment and derivatives infrastructure 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 driven by the current macro environment of supply chain uncertainty, energy shocks, and geopolitical risks," Fariq stated. Options are derivative contracts that grant the purchaser the right to buy or sell the underlying asset at a predetermined price. 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. The two markets, although now matching in scale, are positioned differently, revealing 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. Positioning in Deribit options is also concentrated on the higher side but is slightly more conservative. "Onshore call OI is concentrated roughly 4 percentage points further out-of-the-money than offshore, and the onshore average delta is slightly lower," Volmex noted. Put positioning is largely aligned across venues, with open interest concentrated around the $63,500 strike. ETF holders tend to have a longer-term perspective, with October 2026 expiries preferred in IBIT, while August expiries dominate on Deribit. Lastly, IBIT's implied volatility is higher than the implied volatility derived from Deribit's BTC options, attributed to a structural quirk where ETF holders cannot easily short bitcoin directly. Overall, IBIT's rapid rise in the options market is striking, and the two markets 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. 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.
