In a notable leadership shift at one of the UK’s most profitable financial firms, Hans Buehler has officially resigned from his role as Co-Chief Executive Officer of XTX Markets. Buehler, who joined the electronic trading powerhouse in 2022 as Deputy CEO and was elevated to Co-CEO in 2023 alongside founder Alex Gerko, has also vacated his position on the board of XTX’s corporate entities.
During his tenure, Buehler played a pivotal role in steering XTX’s growth trajectory, helping solidify its reputation as a leading market maker and proprietary trading firm. His departure marks the end of a chapter that saw XTX’s profitability soar, with Gerko now ranked among the UK’s wealthiest individuals and top taxpayers.
Prior to his time at XTX, Buehler spent 14 years at JPMorgan in Hong Kong and London, where he held senior roles including Global Head of Equities Analytics, Automation, and Optimization. He also previously led equity derivatives quantitative research at Deutsche Bank.
According to an XTX spokesperson, Buehler plans to return to academia, building on his previous experience as a Visiting Professor at the Technical University of Munich. He holds a PhD in Financial Mathematics from Technische Universität Berlin.
His exit leaves Gerko as the sole CEO, with industry watchers keen to see how XTX navigates its next phase of innovation and expansion.
