Jane Street Capital

Jane Street is a technology-driven proprietary trading firm and liquidity provider active across exchange-traded securities, derivatives, and digital-asset markets. Quantitative research, automated execution, arbitrage, and inventory management shape its participation rather than a conventional venture-capital mandate. Coverage should examine trading operations, market-making relationships, technology, counterparties, regulatory matters, risk controls, and any disclosed investments relevant to crypto. Individual exchanges, instruments, and portfolio companies retain separate entries unless Jane Street's execution or capital is central to the event.
