Neptune Networks operates Neptune, an institutional fixed-income pre-trade data platform that delivers real-time dealer axes and bond inventory directly into buy-side workflows. Aggregating structured data from 34 global banks, the network surfaces roughly 110k bonds per day at around $2.2T daily gross notional across 33 currencies, helping asset managers identify liquidity opportunities before they trade. Originally an independent, bank-owned utility backed by Anthemis, Neptune is now operated as RealQ, the data-solutions arm of Liquidnet Fixed Income (part of TP ICAP Group). Connectivity is institutional and permissioned - a browser web app, OMS/EMS integrations, FIX, a REST API, FTP/SSH drop copy, and AWS cloud data transfer - with no public developer portal, published OpenAPI, or open SDKs.
