What Jane Street does
Jane Street operates a principal trading and market-making model. It commits firm capital to quote, buy and sell financial instruments, captures trading spreads and execution economics, and manages the resulting inventory and market risk. Its proprietary electronic platforms distribute this liquidity directly to institutional counterparties through FIX connectivity, systematic internalisation and wholesale execution relationships.
Category differentiation
Jane Street is a principal quantitative trading and market-making firm, not an advertising technology vendor, media business or consumer investment platform. Its client-facing systems provide institutional access to proprietary liquidity rather than general-purpose retail trading software.
