BlackRock’s iShares Bitcoin Trust (IBIT) has overtaken Coinbase’s Deribit to lead the global Bitcoin options market. Following last Friday’s contract expirations, IBIT’s open interest in options climbed to nearly $38 billion, compared to $32 billion on Deribit. Traded on Nasdaq, the fund now manages $84 billion in assets, cementing its place as the world’s largest Bitcoin ETF. The milestone underscores the growing dominance of institutional products in shaping Bitcoin’s trading landscape.
