Patrick Chi: From Applied Math Prodigy to Wall Street’s New-Age Trader

In the high-velocity world of quantitative trading, few names emerge as quickly as Patrick Chi’s. A young professional whose academic grounding and early career choices set him on a trajectory toward the heart of Wall Street’s algorithmic ecosystem, Chi is now a trader at Citadel Securities, one of the most influential market-making firms in the world. His story is one of rigorous preparation, smart internships, and decisive entry into a competitive field.

Early Life & Education

While details of Patrick Chi’s family background remain private, what is clear is his rapid academic progress. Chi graduated from Columbia University with a Bachelor of Science in Applied Mathematics in 2020. His choice of discipline was strategic and forward-looking: applied mathematics provides not just theoretical grounding but also practical skills in problem-solving and quantitative analysis, essential in the world of finance and algorithmic trading.

Even before graduation, Chi had built an impressive portfolio of internships. In 2016, he served as a research intern at Reach Advisors; in 2017, he was a quantitative trader at Blackmar Capital LLC; in 2018, he completed a trading internship at Optiver — a globally known market-making and derivatives firm; and in 2019, he interned at Susquehanna International Group (SIG), another major player in quantitative finance.

These experiences immersed him in live trading environments, introduced him to complex financial instruments, and honed his analytical thinking. By the time he graduated, Chi had already experienced some of the most advanced trading floors and analytical cultures in finance — an invaluable edge for a young graduate entering the market.

Entry into Citadel Securities & Career Development

In August 2020, shortly after completing his degree, Patrick Chi joined Citadel Securities. For most aspiring traders, this would be the defining career break — and for Chi, it marked the beginning of a journey into one of the most demanding and technologically advanced trading environments on the planet.

Within Citadel Securities, Chi became part of a generation of mathematically-driven traders who rely on real-time data and algorithmic precision. His role involved analyzing market trends, managing risk, and executing trades across various global markets.

Reports from within the industry describe his typical day as starting before sunrise — reviewing global overnight activity, monitoring pre-market data, and coordinating with international trading desks as the U.S. markets open. It’s an environment defined by speed, constant analysis, and teamwork, where every second and every decimal point can make a difference.

Chi’s specialization reportedly includes American Depositary Receipts (ADRs) and international equities — instruments that bridge global capital markets and require not only strong analytical skills but also a deep understanding of market structure, liquidity, and regulation.

This combination of applied mathematics, strategic internships, and exposure to global market dynamics has made Patrick Chi a strong example of the modern quantitative trader: part mathematician, part engineer, and part strategist.
