OKX recorded $2.1 billion in options notional volume on March 26 — a new all-time record for the exchange. The volume was concentrated in BTC calls at $100K and $105K strikes for April 25 expiry, suggesting institutional desks are positioning for a continued rally. OKX's new real-time volatility surface tool (launched March 24) appears to be driving engagement from sophisticated traders previously exclusive to Deribit.
ETH options on OKX also hit $480M — up 3× month-over-month.
