Bitnomial is a Chicago-based derivatives exchange company that owns and operates U.S. CFTC-regulated subsidiaries — a Designated Contract Market (exchange/DCM), a Derivatives Clearing Organization (clearinghouse/DCO), and a Futures Commission Merchant (clearing brokerage/FCM). It offers leveraged spot, perpetuals, futures, options, and prediction markets on a single regulated venue with crypto margin and settlement. For developers, Bitnomial publishes a public HTTPS REST API (products, orders, fills, block trades, indexes, funding rates, market stats), a real-time WebSocket market-data feed (trade, book, block, status channels), a low-latency binary order-entry protocol (BTP), and a FIX 4.4 API with dropcopy. REST authentication uses HMAC-SHA256 request signing with per-connection credentials. Surfaced as a portfolio company of Electric Capital and enriched by the API Evangelist pipeline.
