According to latest industry reports; BlackRock’s iShares Bitcoin Trust (IBIT) has surpassed Deribit to become the largest Bitcoin options by open interest. According to Bloomberg, as of the latest contract expiry, IBIT had $38 billion in options open interest, while Deribit had $32 billion. This is less than a year after IBIT options launched.
The Rise of BlackRock IBIT From Launch to Market Leader
IBIT was launched by BlackRock in January 2024 to give investors exposure to Bitcoin in a regulated, exchange-traded vehicle without self-custody.
The U.S. Securities and Exchange Commission (SEC) approved options trading on IBIT in September 2024. This opened the door for institutional hedging via options in a regulated framework.
BlackRock IBIT’s assets grew fast; within 341 trading days, it passed $70 billion in assets under management (AUM), as a result of a favorable cost structure; initially, a 0.12 % discount, then a 0.25 %, and strong inflows.
This created a self-reinforcing liquidity cycle because as more capital flowed in, trading depth improved, which in turn attracted more institutional participation.

IBIT vs Deribit in Options Open Interest
Open interest (OI) is the volume of outstanding option contracts not yet settled. As of the most recent expiry, IBIT had $38 billion in options open interest vs $32 billion for Deribit.
This is especially impressive given BlackRock IBIT options only started trading in November 2024. In early 2025, IBIT’s options open interest was already about half of Deribit’s, within just two months of launch.
On-chain and trading data also shows the trend. IBIT’s option open interest is growing fast and its put/call ratio is lower, showing dominant call-side interest. On the other hand, Deribit which has been the long offshore derivatives king since 2016 has reportedly seen its grip loosen as liquidity moves to more regulated venues.
Why Institutional Flows Prefer IBIT Options Venue
Several structural advantages explain why institutional investors are moving to IBIT. IBIT is in the regulated U.S. markets, under SEC oversight. That’s safer for institutional capital concerned with compliance and governance.
Using IBIT means no need to manage private keys or crypto wallets. Coinbase Prime handles custody under institutional standards. As more capital flows in, bid-ask spreads tighten and opportunities get more efficient. Larger orders incur less slippage.
As more institutions allocate to IBIT, more flows follow. This creates a self-reinforcing cycle of capital, liquidity and market depth.
George Mandres of XBTO Trading summed it up saying; “Wall Street players bring substantial capital and trading expertise” which increases liquidity and narrows spreads.
But that doesn’t mean Deribit disappears; a dual ecosystem will likely persist with regulated venues dominating large capital flows and offshore/DeFi venues serving speculative and high-risk participants.

Conclusion
Based on the latest research; The BlackRock IBIT is currently the top Bitcoin options venue for the crypto derivatives markets. In less than a year since options launched on IBIT, open interest has surpassed Deribit.
This means institutional capital and regulated vehicles are now the anchor of derivatives liquidity and the center of gravity in Bitcoin markets has moved to Wall Street.
But risks remain; liquidity stress, regulatory changes and competition from DeFi platforms will be challenges.
