Jane Street Compared With Citadel Securities for New Graduates

Jane Street offers breadth across asset classes while Citadel Securities offers depth in equities and options, and the interview process previews the fit.

Jane Street and Citadel Securities are both electronic market makers, but they are not the same business. Jane Street trades ETFs, equities, options, fixed income, and commodities from one integrated desk built around a rotational training model, while Citadel Securities is narrower and deeper, standing among the two or three largest market makers in United States equities and listed options. The choice between them separates breadth in the first two years from depth in the first two years, and both are legitimate ways to start a trading career.

Jane Street's edge comes from running the same pricing and risk infrastructure across dozens of product lines at once, so a strategy built for a single stock option can be adapted to a corporate bond ETF within the same quarter. A first-year at Jane Street rotates through desks before settling, and the firm treats that rotation as part of the training rather than a delay to productive work.

Citadel Securities concentrates on equities and options market making with heavy technology investment aimed at winning the queue at the exchange matching engine, and the firm's own year is measured in market share and spread capture in the products it already dominates. A first-year at Citadel Securities sees fewer product lines but a faster path into production grade market microstructure work.

At Jane Street, a first-year is evaluated on trading judgment shown across the desks they rotate through, and feedback is qualitative, delivered by senior traders who worked alongside them that week. There is no single number a first-year is chasing early on, since the rotational period exists so judgment can be assessed before a permanent desk assignment is made.

At Citadel Securities, a first-year on a market making desk is closer to a live profit and loss from the first months, because the strategies they support are already running in production, and small improvements to a pricing model show up in that day's numbers. The measurement is faster and more numeric than Jane Street's early rotation model.
