Jane Street, a global heavyweight in quantitative trading and market making, is set to significantly expand its office footprint in Hong Kong. According to sources with direct knowledge of the matter, the New York-based firm is currently in advanced negotiations with property owner Hongkong Land over leasing two additional floors in Chater House, a prominent office tower in the Central business district. If the deal comes to fruition, Jane Street will occupy six floors in a 30-story building, boasting a total office space of over 10,000 square meters—an impressive leap from the 2.5 floors it occupied just a year ago. Both Jane Street and Hongkong Land have declined to comment on the discussions.
