Jane Street, the famously secretive Wall Street trading firm, is undergoing a strategic rebrand as it tries to become a major artificial intelligence player. The company, founded 26 years ago and now employing about 3,500 people, plans to hire 500 more this year while using AI to improve its trading models, even if that means giving up some of the discretion that long defined it. The shift was reported Saturday by The Wall Street Journal.
The firm, whose profits now exceed those of giants such as Goldman Sachs and Morgan Stanley, is trying to signal to top technology talent that it has the computing power to support advanced AI work. In April, Jane Street agreed to invest $1 billion in CoreWeave and committed to spend another $6 billion on the company’s cloud platform. Unlike its usual approach, it insisted the deal be announced publicly, surprising even business partners.
Jane Street has also built a $20 billion private investment portfolio that includes a stake in Anthropic. Its core business is market-making across assets including stocks, bonds, options, commodities and crypto, using algorithms to find price gaps, including discrepancies between exchange-traded funds and their underlying holdings. That strategy helped it post a record $10.3 billion profit in the first quarter of 2026.
The company’s move into public visibility is not without risk. In recent years it has faced accusations of market manipulation, employee poaching disputes, insider trading claims, all of which it has denied. It also dealt with reputational damage after one co-founder said he was duped into funding a failed attempted military coup in South Sudan. Founded in 2000 by three former Susquehanna trading executives and an IBM developer, Jane Street now sees openness as necessary to compete in a world where more data and more computing power are becoming essential.
