The U.S. Options Open Interest dataset provides daily open interest information for U.S. equity and index options, derived from Options Price Reporting Authority (OPRA) open interest publications. The dataset consolidates open interest across all U.S. equity options exchanges, delivering contract-level visibility into the number of outstanding option positions at the end of each trading day. Open interest values are provided per option contract, enabling analysis of market participation, liquidity concentration, positioning trends, and risk exposure across strikes, expirations, and option types.
