Xantium

Xantium is Paul Tudor Jones's bet that quants and fundamental analysts belong in the same room. Spun up inside Tudor Investment Corporation in 2020 by four of its veterans, it deliberately keeps human discretion alongside systematic research rather than going pure-machine, pricing securities and building portfolios across asset classes globally.

The division is now preparing to leave the nest: reports point to a standalone launch around early 2027 with roughly five billion dollars, which would rank among the larger recent hedge fund debuts. Core teams sit in London and New York, with people in Salt Lake City and Stamford and a planned Abu Dhabi office. In the UK it trades as Tudor Capital Europe LLP.
