Option Greeks measure how iShares Bitcoin Trust ETF (IBIT) option prices respond to changes in the stock price (delta and gamma), the passage of time (theta), implied volatility (vega), and interest rates (rho). These charts plot each Greek by strike, so you can see where an expiration's price risk, time decay, and volatility exposure are concentrated.

IBIT Option Greeks FAQ
What are option Greeks?
Option Greeks measure how an option's price responds to changes in the stock price (delta and gamma), time (theta), implied volatility (vega), and interest rates (rho).
How do I read the IBIT Greeks charts?
Gamma, theta, and vega are largest for strikes near the IBIT stock price and shrink for strikes far above or below it. Theta grows as expiration gets closer, while vega is larger for expirations further out. Call delta runs from 0 to 1 and put delta from -1 to 0, near 0.50 and -0.50 at the money, and roughly estimates the chance that an option finishes in the money.
How does implied volatility affect IBIT's Greeks?
IBIT IV rank is 10, so implied volatility is near the bottom of its one-year range. Higher implied volatility raises option premiums and daily time decay (theta), and spreads delta and gamma across a wider range of strikes. Over the past year, 30-day implied volatility ranged from 32.4% to 85.7%. See the IBIT implied volatility history for a longer view.
How much gamma and delta do IBIT options carry in total?
Across all open IBIT options on Nov 11, 2026, net gamma exposure was $2.94M and net delta exposure was $422.55M per 1% move in the stock. The IBIT gamma exposure chart shows where that gamma sits by strike.
