$39 billion, setting a new record on Wall Street.

Many people think that the biggest winners of the AI era will be model companies like OpenAI and Anthropic.
But in reality, the most profitable are still those quant machines armed with mathematics, computing power, systems engineering, and capital efficiency.
And Jane Street is essentially a super AI agent in the financial world.
A company with over 3,000 employees, it is one of the world's most important quantitative market makers, active in 45 countries and over 200 trading platforms, covering ETF, stocks, options, bonds, forex, and other asset classes.

In 2025, Jane Street paid out $9.38 billion in compensation to its employees.
Based on approximately 3,500 employees, the average salary is about $268,000, equivalent to roughly 18.29 million RMB.
Jane Street’s per capita salary is about seven times that of Goldman Sachs.
Even for newcomers, the quantitative traders positions for fresh graduates at Jane Street can have a base salary of around $300k, not including bonuses.
After DeepSeek became popular, Jane Street is often discussed alongside Liang Wenfeng and Fantasia Quant.
Because their underlying qualities are too similar.
Both are low-key.
Both started from quant.
Both believe in mathematics, models, engineering, and computing power.
Both do not follow traditional internet narratives.
Behind them are groups of people accustomed to modeling, calculating, and betting in uncertainty.
Liang Wenfeng ultimately incubated DeepSeek.
Jane Street did not develop large models on its own but chose to heavily invest in the AI industry chain.
It invested in Anthropic and also appears behind AI companies like CoreWeave and Thinking Machines Lab.
