BlackRock’s IBIT Options Surpass Deribit in Open Interest, Signaling Institutional Shift

The landscape of Bitcoin derivatives has shifted significantly, with open interest (OI) for options linked to BlackRock's iShares Bitcoin Trust (IBIT) on the Nasdaq now exceeding the total Bitcoin options trading on Deribit. This milestone marks a pivotal moment in the institutionalization of the cryptocurrency market, as regulated U.S. infrastructure moves from a secondary role to a primary driver of liquidity. While Deribit has dominated the offshore options space since 2016, IBIT options have closed the gap in just two years. According to data from Volmex, IBIT options open interest reached $27.61 billion on Friday, slightly edging out Deribit’s $26.90 billion. This growth provides U.S. retail and institutional investors with regulated access to leverage and hedging strategies that were previously confined to offshore platforms. The positioning within these markets reveals a strongly bullish outlook among U.S. investors. IBIT call options indicate expectations for Bitcoin to rally toward $109,709—approximately 41% above the current market price of $77,400. In comparison, positioning on Deribit is slightly more measured, suggesting a rally target of $106,000. Analysts note that the U.S. market is currently dominated by retail upside speculation and systematic call overwriting programs. Furthermore, the preference for longer-dated contracts—specifically October 2026 expiries for IBIT compared to August expiries on Deribit—suggests a shift toward long-term strategic positioning by Wall Street participants.
