Bitwise's Jeff Park said open interest in BlackRock's IBIT options has overtaken offshore derivatives for the first time, framing the shift as the setup for a volatility-driven Bitcoin rally led by IBIT options.
Why it matters
The crossover is structurally significant: until now, leveraged BTC exposure primarily cleared through offshore perps and CME futures. A US spot ETF options book leading the complex changes the dealer-flow map — market makers hedging IBIT options will increasingly have to trade spot BTC or microstrategy proxies to manage gamma, pulling new liquidity into the on-chain and ETF market plumbing.
Market impact
The near-term read is higher realized and implied volatility around BTC price discovery, not directional in itself. A growing dealer short-gamma position tends to amplify moves in whichever direction spot breaks; a flat tape punishes option sellers. Park's framing is that the IBIT options complex is now large enough to be the volatility engine for Bitcoin itself, with offshore perps reacting to moves the ETF options book initiates rather than the other way around.
